Be vigilant on United Nations Diabetes Day! Complications of diabetes are harmful

       CCTV News:Studies have shown that long-term hyperglycemia can cause organ dysfunction or failure in patients, so preventing complications has become a top priority. At the same time, standardized treatment and rational drug use are also very important.

       Complications of diabetes include retinopathy, uremia and foot disease. Diabetic retinopathy is the main cause of blindness in adult population; Diabetic nephropathy is one of the common causes of renal failure. In addition, the risk of cardiovascular and cerebrovascular diseases in diabetic patients is 2-mdash higher than that in non-diabetic people of the same age and sex; Four times.

       The medical staff suggested that diabetic patients with complications must be actively treated and used correctly, and the dosage should not be blindly increased because of complications, because increasing the use of hypoglycemic drugs is likely to cause hypoglycemia, and the harm caused by hypoglycemia is more serious than complications.

Read the article and release the annual original IP list, and the "post-90 s" writers contribute more than half of the online reading income.

On the evening of June 3rd, the 6th Reading Original IP Festival was held in Shanghai. As the "wind vane of IP development", Shengdian announced the annual heavy original IP list, including annual theme works, annual overseas works, annual top ten male/female popular works, annual adaptation expectation works and many other projects.

According to Cheng Wu, CEO of Reading Group, vice president of Tencent Group and CEO of Tencent Pictures, the value of IP development lies in "making good stories endless". "While good stories are constantly emerging, they also enrich the connotation and extension through various forms such as video games".

The newly released "Xinhua Cultural Industry IP Index Report" shows that at present, China’s Internet native IP is rising, potential writers and high-quality works are constantly emerging, and at the same time, the concentration effect of online literature IP incubation is strengthened, injecting new vitality into industrial development. The data shows that the online literature writers are constantly injecting fresh blood, showing the characteristics of being younger and more diverse. The "Z generation" writers and readers have become the mainstay of the industry.

Nearly 80% of the new writers in the reading platform in 2020 are "post-95 s", and the "post-90 s" writers have contributed more than half of the online reading income. Among them, the post-90s writers, Eagles Eat Chickens and Little Langjun Selling Newspapers, respectively, set a new monthly ticket and subscription record for online literature in the past 20 years with their two works, The Robbery of All Ethnic Groups and Da Feng Da Geng Ren.

That night, "Da Feng Da Geng Ren" included the four titles of "Best Works of the Year", "Top Ten Men’s Frequencies of the Year", "Oriental Fantasy Works of the Year" and "Expected Works of Film and Television Adaptation of the Year" in one fell swoop, making it one of the most eye-catching works on the list. "The author integrates common routines and uses excellent characterization and plot structure skills to create tension between characters and story clues, which brings readers a relaxed and pleasant reading experience." Zheng Zhang, an associate professor at Tsinghua University School of Journalism and Communication, commented.

Ye Feiye, a platinum writer of Reading Group, won the title of "Best Writer of the Year" and "Talking Elbow" won the title of "Honorable Writer of the Year". Ye Feiye won the first place in the monthly ticket list for girls in the original literature billboard for four years in a row, and her works have more than 10 billion hits on the Internet, which has set a new record for the electronic daily sales of single works for many times. Her representative works include I like tomorrow, I share half of my room with you, I like you, I decide, and my husband takes it home. Last year, "Talking Elbow" once again refreshed the popularity of works with the same theme with "The First Sequence", which was collected by the National Library together with his book "The King forgives his life". The new book "Naming of the Night" has also set a record for refreshing the first payment according to the number of hours since it was put on the shelves.

At the same time, the younger readers have also brought a new atmosphere in the field of online writing. The 2021 annual conference of reading articles held on the same day revealed that 70% of the active users of reading articles’ apps are under the age of 30, and the secondary theme loved by young people has risen, and the proportion of light novels has increased by 370% in three years. Young readers are keen on interaction and comments. In 2020, the number of "This Chapter" readings was nearly 100 million, which contributed more than 32% to the improvement of users’ per capita reading time and 10% to the improvement of users’ payment rate.

"To build an influential and vital IP, the key lies in long-term development planning." Zou Zhengyu, head of the copyright business of Yuewen Group, said that Yuewen platform has launched a series of plans in terms of audio content, physical book publishing, animation adaptation and game development. "For example, the audio work of" Da Feng Da Geng Ren "was launched for two months, and the broadcast volume of the whole network broke 40 million; The broadcast volume of "Men Out of Xianmen" reached 3.5 billion, and the audio works of "Waifu" also formed a very strong IP linkage effect during the TV series. "

In addition, in terms of comics, it is expected that more than 100 works, such as "The Dragon Shepherd" and "Above the Dome", will be developed simultaneously this year, and the first batch of more than 30 web IP’s that cooperate with Quick Watch Comics are also being changed. In terms of animation, IP content covers six series: legendary story, future fantasy, urban superpower, youth adventure, super-burning competition and heart-pounding. Recently, more than 50 films are being developed, including Da Feng Da Geng Ren, The First Sequence, Starting from the Red Moon, Ghost Blowing Lights and Global Martial Arts. In terms of games, IP-authorized games such as Douluo Mainland, Ghost Blowing Lights, Master of Secrets and Biography of Immortals will also be launched one after another.

"Reading will also take measures such as creative encouragement, work support, adaptation recommendation, etc., and within three years, the number of newly signed writers under the age of 30 will double, the remuneration will double, and the new gods will double. By supporting new writers and young writers, the creative ecology will be further activated." Yang Chen, vice president and editor-in-chief of Reading Group, said.

Meteorological Response in Agricultural Transformation Period —— Summary of Meteorological Service for Agriculture since the 18th CPC National Congress

 China Meteorological News reporter Niu Yanyuan Lai Min Intern reporter Zhang Hongwei Lai Yuwen

  Agriculture is always regarded as a basis for national stability and for people’s security.

  Since the 18th National Congress of the Communist Party of China, the pace of agricultural modernization has been accelerating.

  We have heard that the transformation and upgrading of agricultural development mode urgently calls for meteorological services.

  We have seen that the meteorological department has the courage to take responsibility and dare to transform, and in the journey of strengthening the modernization of meteorological service agriculture, ensuring national food security and the supply capacity of important agricultural products, it has handed over satisfactory answers during the agricultural transformation period.

  National Top-level Design Calls for Policy Landing —— Keep up with the trend of change and development, and implement practical measures to highlight actual results.

  On March 20, 2015, Bai Hongxia clearly remembered that there was a gratifying spring rain that day.

  Bai Hongxia is an agricultural technology information officer at the regional station of agricultural technology extension in Xindian Town, Luohe City, Henan Province. That morning, holding a microphone, she introduced the modern agrometeorological service platform to Wang Yang, Vice Premier of the State Council, who came to inspect. "As an important part of the Internet of Things system integrating soil, fertilizer, water and gas in high-standard grain fields, the modern agricultural meteorological service platform can integrate real-time farmland monitoring data, make targeted and refined agricultural meteorological service products, and then send them to farmers in various ways."

  On the same day, the National Conference on Spring Agricultural Production and Forest and Grassland Fire Prevention was held in Luohe. Wang Yang pointed out at the meeting that it is necessary to continue to strengthen meteorological capacity building and improve the service mechanism, especially to meet the new requirements of agricultural transformation and structural adjustment, and actively provide personalized, diversified and professional services while doing a good job in universal meteorological services. It is necessary to improve the accuracy of monitoring and early warning of abnormal weather and meteorological disasters in key agricultural seasons, and strengthen the direct meteorological service for new business entities and the whole agricultural production chain.

  Transformation has become a general trend.

  This is a five-year period of profound changes in the field of agriculture, rural areas and farmers, and a five-year period of constant changes in the demand for meteorological services for agricultural development.

  Keeping up with the development trend, the No.1 Document of the Central Committee, which guides the work of agriculture, countryside and farmers in China, continues to emphasize increasing investment in meteorological services for agriculture, and the requirements for meteorological services are more clear.

  In 2013, "accelerate the construction of rural meteorological information service and weather modification work system and capacity, and improve the level of agricultural meteorological service and rural meteorological disaster prevention".

  In 2014, "improve the rural grassroots meteorological disaster prevention and mitigation organization system and carry out direct meteorological services for new agricultural business entities".

  In 2015, "innovate the service mechanism of meteorology for agriculture and promote the integration into the agricultural socialized service system".

  In 2016, "strengthen the construction of meteorological service system for agriculture, vigorously develop the application of intelligent meteorology and agricultural remote sensing technology, and explore the pilot of weather index insurance".

  Take advantage of the situation and follow the trend. China Meteorological Bureau paid close attention to the implementation of the No.1 Document of the Central Committee, focused on the national "agriculture, rural areas and farmers" work, made continuous efforts in optimizing the system and mechanism, innovated the means of supporting agriculture and benefiting farmers by meteorology, improved the agricultural meteorological service system and the rural meteorological disaster prevention system (referred to as the "two systems" for short), built a long-term mechanism, and improved the national agricultural meteorological business system, etc., and outlined a clear path for the development of meteorological services for agriculture.

  Sit and seek, get up and go. In the hard work, a series of meteorological service initiatives for agriculture have landed.

  In the past five years, the meteorological department has taken it as its own responsibility to cope with climate change and escort food security, and issued the Blue Book of Assessment Report on the Impact of Climate Change on Agriculture in China twice, so as to create special meteorological services for the whole process of key farming seasons focusing on ensuring food security, and provide scientific reference for food production, management, supply and marketing scheduling, storage and transportation, and trade.

  In the past five years, the meteorological department has continuously promoted the deepening of departmental cooperation, established an agrometeorological expert alliance composed of experts in meteorology, agriculture, forestry, water conservancy, plant protection and other fields, and promoted the establishment of timely and effective information exchange network systems and data product sharing lines among departments; Realize the docking and integration with the service organizations and resources of grass-roots supply and marketing cooperatives, and incorporate new agricultural business entities such as agricultural and sideline products business enterprises, township grass-roots cooperatives and farmers’ cooperatives into the direct service targets of meteorological departments to promote service quality and efficiency.

  In the past five years, the meteorological department has actively served the construction of advantageous areas of characteristic agricultural products, and jointly promoted the establishment of a characteristic agricultural meteorological service center with "one province as the mainstay, multi-province participation and linkage between ministries and provinces" with the Ministry of Agriculture, and gradually established a characteristic agricultural meteorological service network with different varieties and regions to realize the intensification, standardization and branding of characteristic agricultural meteorological services.

  The real move is landing, and you can see the actual results-

  By 2016, 123 standardized modern agricultural meteorological service counties and 1009 standardized meteorological disaster prevention towns and villages have been built nationwide.

  Since 2011, the national public’s satisfaction with meteorological services has remained above 85 points, of which the rural public’s satisfaction with meteorological services reached 88.9 points in 2016.

  In the past five years, the accuracy of the national total grain output forecast has been stable above 99.9%, and the accuracy score of the provincial total grain output forecast has reached 98.1 points.

  The new agricultural structure calls for deep service-multi-department "ensemble" to enrich the connotation of "two systems"

  Only by going deep into the vast fields can we truly feel the "popularity" of direct meteorological services.

  In yushu city, Jilin Province, Chen Zhuo, head of Tian Feng Machinery Planting Professional Cooperative Association, and Xu Liping, head of Agricultural Meteorological Service Section of Municipal Meteorological Bureau, are old friends. "There is my contact information in the early warning information publishing platform. When there is unfavorable weather, I will receive the reminder at the first time." Chen Zhuo said. In Weichang County, Hebei Province, Ding Mingya, Chairman of Potato Industry Alliance, and Zhu Guoliang, Director of County Meteorological Bureau, are "iron buddies". "There are special observation stations in the plantation, and meteorological data will be transmitted to me in real time." Ding Mingya said. In Liupanshui City, Guizhou Province, Gu Yonglong, the head of the Red Heart Kiwi Industrial Park in Miluo Township, is very close to Chi Zaixiang, a senior engineer of the Municipal Meteorological Bureau. "The ulcer prevention and control system specially developed by the Meteorological Bureau can give an early warning one or two months in advance, which has reserved sufficient prevention and control time for us." Yan Yonglong said.

  In the new wave of comprehensive rural reform, new types of agricultural business entities are constantly emerging. These new agricultural business entities have large scale of operation, high yield level and greater losses due to disasters, so the demand for meteorological information and technical measures for disaster prevention and mitigation is more urgent. In 2014, the No.1 Document of the Central Committee explicitly requested the development of direct meteorological services for new agricultural operators.

  Subsequently, the China Meteorological Bureau and the Ministry of Agriculture jointly launched a direct meteorological service for new agricultural business entities, namely, agricultural meteorological service products changed from "universality" to "personalization", service delivery mode changed from "general style" to "direct style", and service language changed from "jargon" to "local accent". At present, 982,000 new agricultural business entities enjoy "point-to-point" direct meteorological services, and nearly 2.4 million registered users of intelligent agricultural meteorological terminals.

  Direct meteorological services can "spread branches and spread leaves", which is inseparable from the increasingly perfect fertile soil of "two systems" of meteorological services for agriculture.

  In the past five years, the connotation of the construction of "two systems" of meteorological service for agriculture has been continuously enriched:

  In 2013, efforts were made to establish standardized meteorology to serve agriculture in counties (cities, districts) and townships (towns).

  In 2014, the central government will drive local finance to jointly invest, strengthen the long-term mechanism construction of meteorological services for agriculture and direct meteorological services, build standardized meteorological services for counties (cities, districts) and townships (towns), and continue to promote the equalization of grassroots meteorological services.

  In 2015, we will innovate the meteorological service mechanism for agriculture, promote the integration of meteorological service for agriculture into the agricultural socialized service system, and serve agricultural modernization and new rural construction.

  In 2016, innovating the effective supply mode of meteorological services for agriculture, developing an intelligent and efficient meteorological service system with clear responsibilities and rights, and enhancing the ability of meteorological support for accurate poverty alleviation services have become the main lines of work.

  In the past five years, meteorological service for agriculture "two systems" construction has written a brilliant report card:

  Nowadays, China’s rural meteorological disaster monitoring and early warning information dissemination capabilities have been significantly enhanced, and a rural meteorological disaster prevention system has been basically established. By the end of 2016, 57,000 regional automatic weather stations had been built in rural areas nationwide, with a township coverage rate of 95.9%; Organize and complete the general survey of meteorological disaster risk in all districts and counties in China, and organize and complete the compilation and application of flood and flash flood risk zoning maps for more than one third of small and medium-sized rivers in China; In 2167 counties, meteorological disaster prevention and mitigation or meteorological services for agriculture were established, and in 2018 counties, meteorological disaster prevention plans were issued.

  Nowadays, China’s agricultural meteorological service business system is becoming more and more perfect, and the service level is steadily improving. By the end of 2016, China had built a modern agrometeorological observation network consisting of 653 agrometeorological observation stations, 2,175 automatic soil moisture observation stations and 1,895 farmland microclimate observation stations. Meteorological services were integrated into the construction of high-standard grain fields, and 1312 agricultural meteorological demonstration fields were built, and the demonstration and promotion area of agricultural meteorological disaster prevention and mitigation technology was nearly 50 million mu; The development of characteristic agrometeorological services is in full swing, and 28 agrometeorological sub-centers have been established in 10 provinces according to regions or crops.

  The construction of "two systems" of meteorological service for agriculture is an ensemble of many departments. China Meteorological Bureau and the Ministry of Agriculture jointly issued agricultural pest and disease disaster forecast, agricultural drought monitoring and forecast, jointly issued a document with the Ministry of Land and Resources to promote meteorological forecast and early warning of geological disasters, and jointly carried out meteorological grade forecast and visual consultation with the State Forestry Administration; The meteorological bureaus of all provinces (autonomous regions and municipalities directly under the Central Government) cooperate with civil affairs, women’s federations, public security, supply and marketing departments to build a team of meteorological information officers. The rural economic information network sponsored by governments at all levels, undertaken by meteorological departments and co-organized by agriculture-related departments covers more than 270 cities (districts) and more than 1,300 counties in 31 provinces … In the linkage of departments, the "two systems" of meteorological services for agriculture continue to grow and develop.

  It can be seen that a nationwide rural meteorological monitoring, forecasting and information service system network has been formed, and the "two systems" of meteorological services for agriculture are gradually becoming an important way for meteorological services to extend to the grassroots.

  The development of modern agriculture calls for the support of science and technology-gathering the strengths of many "technologies" to accurately cure the "pain points" of farmers

  Nowadays, agricultural production has already bid farewell to the passive situation of "facing the loess and facing the sky", high technology has become a new support for development, and the fruits of meteorological science and technology have benefited the whole country.

  In Jiangxi, to meet the needs of modern agricultural development, it is necessary to have the ability of self-perception, judgment, analysis, selection, action, innovation and self-adaptation in the whole process of agrometeorological business, service and management. The "Jiangxi Micro-farmers" developed by the local meteorological department can automatically match farmers and managers in different regions. It is not difficult to provide refined and targeted services. Using big data classification management technology, services can more accurately cure farmers’ "pain points".

  In Anhui, the meteorological department established the "Chuhe Network Community", and developed the "Huinong Meteorology" APP with the support of agro-meteorological Internet of Things technology.

  In Fujian, meteorological departments use technologies such as Internet of Things, wireless communication and software to provide farmers with services such as monitoring information inquiry inside and outside greenhouses, weather forecast and early warning, agricultural production suggestions and remote control of intelligent greenhouses.

  In Chongqing, the Municipal Meteorological Bureau has developed a refined intelligent service platform for agrometeorology, and set up a working subsystem, an intelligent service website, a "PDA" subsystem and a business monitoring system for agrometeorology …

  For science and technology departments, only by intensive cultivation around "technology", can the soil where meteorology serves agriculture be more fertile. In the past five years, meteorological science and technology elements have been integrated into all aspects of agricultural production:

  During various farming activities, the meteorological department provides agricultural producers with monitoring and forecasting information of agro-meteorological conditions and monitoring, evaluation and early warning information services of agro-meteorological disasters by making full use of technologies such as automatic observation of agro-meteorological based on the Internet of Things, gridded forecasting based on refined numerical weather forecasting products, and quantitative evaluation based on the fusion of crop models and remote sensing.

  In terms of adjusting industrial structure in response to climate change, the meteorological department carried out analysis based on high-resolution satellite remote sensing and radar detection data, and completed 7,205 detailed agro-climatic zoning and agro-meteorological disaster risk zoning.

  In the prevention and control of pests and diseases, meteorologists carry out joint research across departments to clarify the main types of pests and diseases that harm large crops and the index of damage degree, and provide decision-making services for agricultural departments to formulate pest control plans, adjust agricultural structure, and arrange crops.

  In the application of agro-meteorological applicable technologies, meteorological departments and agricultural departments have established an effective cooperation mechanism to carry out technology research and development and demonstration and popularization according to local conditions.

  The close-knit and intimate services in meteorological services for agriculture all reflect the concept that "it is necessary to strike while the iron is hot". Nowadays, the technology of agro-meteorological disaster lattice impact prediction and risk early warning developed by meteorological department has been applied in business, and the precision of remote sensing monitoring of crop growth and yield estimation, agro-meteorological disasters and pests and diseases has been continuously improved; 38 national agro-meteorological technical standards and business norms were compiled and revised, 5,548 local agro-meteorological indicators were formulated, and more than 60 applicable agro-meteorological technologies were developed and popularized.

  The supporting force behind this series of scientific and technological innovations is that meteorological, agricultural and other departments organize experts to design and popularize their applications. Colleges and universities participate in research and development, and the alliance of experts at home and abroad involved in agriculture acts as a "think tank". The essence and technology of industry and universities form a joint force in the field of meteorological services for agriculture to jointly improve service capabilities.

How do children "charge for 5 minutes and talk for 2 hours"

  I remember the first time I saw the slogan "charge for 5 minutes and talk for 2 hours", I immediately thought of those children who were alive and kicking all day. They are almost tireless in playing. They will be noisy in scenic spots or playgrounds until all the electricity is consumed. Then, in their parents’ arms or in the back seat of the car, they are still drinking or talking one second and falling asleep the next.

  Next, it may often take only an hour to rest, and they can "resurrect with blood" and continue to play wildly. The reason why the baby is so tired is also a great reason.

  However, although we all know this feature of children, do you know the reasons behind it? Why is there so much energy in their small bodies?

  Comparable to triathletes.

  At present, the most famous research on the amazing potential of children in anti-fatigue is an experiment done by researchers at the University of clermont-ferrand: they recruited three groups of volunteers, each with 12 people, who were national male athletes engaged in triathlon, cycling or long-distance running; 12 boys with an average age of 10 and a half; And 12 ordinary adult men who rarely engage in strenuous exercise participated in the study.

  These three groups of volunteers were asked by the researchers to do two sets of 7-second cycling sprints, and then pedal their bicycles as soon as possible for 30 seconds.

  After exercise, the researchers compared the energy production of different groups of volunteers, including aerobic exercise and anaerobic exercise. Among them, anaerobic exercise does not consume oxygen, but will produce a lot of lactic acid, which will cause muscle fatigue.

  After that, the researchers compared the recovery rate of heart rate, blood oxygen level and lactate clearance rate of different groups of volunteers after exercise. Finally, the researchers found that children are not easily exhausted by cycling, which is equivalent to the fatigue of professional athletes.

  In fact, in all tests, children’s physiological function performance is better than that of untrained adults, and their physical strength recovery speed is faster than that of professional athletes.

  Muscle structure has advantages.

  Although the experimental results are surprising, this advantage of children’s undeveloped body is not accidental, it is the result of children’s special body structure.

  Don’t treat children as miniature adults, they are all "Little Superman" — — As far as muscle composition is concerned, children’s muscles are composed of 70% red muscle fibers and 30% white muscle fibers, while in adults’ bodies, red and white muscles account for 50% respectively.

  This particularity of muscle structure means two completely different energy production mechanisms. White muscle fibers are mainly supplied with energy through anaerobic, that is, creatine phosphate (a high-energy molecule) and sugar (glucose) are directly supplied with energy, which can make muscles release strong explosive force in a short time. In contrast, red muscle fibers are powered by aerobic respiration.

  Red muscle contains a large number of "small factory" mitochondria, which can use more oxygen and make the production more efficient. Therefore, although it is inferior to white muscle in explosive power and strength, red muscle has stronger endurance.

  If an adult still has a lot of red muscle fibers, it is mostly inherited or the result of high-intensity training. But children do not benefit from training, but are born to be comparable to endurance athletes.

  Small body shape is more divided

  Children’s infinite energy not only comes from their unique muscle structure, but also benefits from their small body shape, which makes them have an extremely fast oxygen supply speed before their height soars in adolescence, and can deliver oxygen to all motor muscles in a short time to provide energy in time.

  "It’s like the difference between a mouse and an elephant. Mice are small in size and have high oxygen demand, mainly relying on aerobic energy supply system; Elephants that are huge and bulky rely on anaerobic energy supply systems. " Sebastian Ratel, the leader of the research project, said, "In small animals, it takes much shorter time to transport oxygen."

  As for the recovery speed, the experiment shows that the recovery rate of heart rate in children’s group is 85%, that of athletes is 60%, and that of untrained adults is only 40%.

  Researchers attribute this outstanding performance of children to a more effective acetylcholine inhibition mechanism — — This neurotransmitter can slow down the beating speed of the heart through the parasympathetic nervous system (controlling the autonomous operation of the body).

  Children also have outstanding performance in removing metabolic waste from the body. You know, metabolic waste is the culprit that disturbs muscle contraction. The research team tested the content of lactic acid in the blood of the tester — — Lactic acid is a metabolite produced by muscle fatigue. The test results show that compared with endurance athletes, children’s lactic acid disappears faster, and ordinary adults are far behind in this respect.

  "Lightning speed" is the wonder of researchers for children’s physical recovery ability. They analyzed that this may be because children are smaller and their muscles are closer to the oxygen-rich blood pumped by the heart, so they can use oxygen more effectively. Children’s extra energy comes from slow muscle fibers, which contract slowly, protecting children from being injured by excessive exercise.

  No need to exercise deliberately.

  Although the metabolic ability is not limited by body shape, children’s legs are not strong enough, coordination is insufficient, and the toughness repair ability of tendon system is weak, which leads to low body efficiency and limited mechanical movement ability. It is true that children’s quick recovery makes people feel never tired, but it is not the case when they exercise for a long time.

  After children enter adolescence, their bodies gradually turn to rely on anaerobic system, which, like their adult parents, makes them tired easily and slows down their recovery. Therefore, before puberty comes, it is best to focus on cultivating their sports skills and action effectiveness through coordinated exercise and motor function exercise, so as to improve sports efficiency, rather than focusing on improving aerobic metabolism, because children’s aerobic metabolism efficiency is already very high.

  Therefore, there is no need to deliberately do aerobic exercise in childhood. On the contrary, from adolescence, it is necessary to continuously improve the motor function and efficiency of the body. Since children’s bodies grow rapidly and have a brand-new body cognition after entering adolescence, it is necessary to focus on improving aerobic metabolism at this time to maintain the body’s rapid recovery ability, delay the onset of fatigue, and prevent diabetes, obesity, insulin resistance and cardiovascular diseases.

  Mentality and sleep also help.

  In addition to the characteristics of physiological function, children’s mentality is a model of "living in the present". They devote themselves wholeheartedly to the present activities, crying if they want to, smile happily, naive and carefree, while we adults bear all kinds of pressures and worries of life every day, and have a lot of depressed negative emotions, which is also a great consumption of physical vitality and energy.

  Needless to say, children can generally get much more abundant sleep recovery time than adults. According to the statistics of national data, the average sleep time of children under 5 years old is 10 ~ 12 hours, which is beyond our adults’ reach. (brown squirrel)

General Administration of Market Supervision: It will issue opinions with relevant departments to improve the consumption environment and start the establishment of a national demonstration city for a

Cctv newsThe State Council Press Office held a routine briefing on the State Council policy this afternoon (July 31). Kuang Xu, director of the Law Enforcement Inspection Bureau of the General Administration of Market Supervision, introduced at the meeting that as the lead department for protecting consumers’ rights and interests, the General Administration of Market Supervision thoroughly implemented the decision-making arrangements of the CPC Central Committee and the State Council, made great efforts to create a secure consumption environment and promote consumption quality and expansion. Specifically, it includes three aspects: building the system, keeping the bottom line and raising the line.

First, constantly improve the laws and regulations and consolidate the institutional foundation of the consumption environment.General administration of market supervisionFocusing on new situations and new problems in the field of consumption, we actively responded to consumers’ concerns, and revised a series of rules and regulations, such as the Measures for the Supervision and Administration of Online Transactions, the Provisions on Clearly Marking Prices and Prohibiting Price Fraud, the Measures for the Administration of Internet Advertising, and the Measures for the Administration of Contract Supervision, so as to promote the overall construction of a coordinated supervision pattern of the consumption environment. Focus on new formats such as blind box management, duty-free online shopping, and new energy vehicles, issue normative guidelines, carry out administrative guidance, and implement defective product recalls, and guide emerging fields such as home appliances, automobiles, duty-free, blind boxes, and e-commerce to improve after-sales service and boost consumer confidence.

The second is to continuously strengthen supervision and law enforcement and purify the market consumption environment. Safety is the premise of consumption. Market supervision departments continue to promote the "iron fist" action in the field of people’s livelihood, and severely crack down on the problems that the masses have strongly reflected, such as illegal food addition, fake and shoddy products, advertisements of "magical medicine" and medical beauty chaos. Since the beginning of this year, more than 350,000 cases in the field of people’s livelihood have been investigated. Focusing on consumers’ concerns, we have successively carried out special actions such as lighting up hundreds of e-commerce platforms, protecting the safety of children’s and students’ supplies, improving the quality of dairy products, and improving the quality of catering, so as to enhance the satisfaction of people’s daily consumption. This year, the General Administration will also comprehensively publicize consumer complaint information, promote the formation of a closed loop of consumption-evaluation-supervision, and guide operators to enhance their awareness of honesty and law-abiding and the quality of goods and services.

The third is to comprehensively carry out consumer confidence actions to enhance consumers’ sense of acquisition.General administration of market supervisionTogether with 26 departments, we will guide all industries and regions to improve the soft power of the consumption environment, fully mobilize the enthusiasm of operators and consumers, and build a large number of regional brands such as assured shops, assured markets, assured neighborhoods, assured scenic spots, assured villages and "satisfied consumption Yangtze River Delta" nationwide to stimulate urban and rural consumption. Actively explore the transformation of credit assets of assured consumers, and use financial "assured loans" to enhance the sense of acquisition of the real economy and small and micro enterprises. Continue to promote offline return without reason, local shopping in different places, advance payment and rapid return, and 654,000 physical stores across the country have returned about 5.38 billion yuan. Improve the online dispute settlement mechanism of the national 12315 platform, promote 132,000 enterprises to settle in the platform, and promote 16.5% of consumer disputes to be directly resolved at the source. Carry out the food safety "you check me" service to benefit people’s livelihood. More than 60 million people have participated in the spot check activities, and the sampling amount is close to 320,000 batches, building a "heart-to-heart bridge" to serve the people.

Kuang Xu said that in the next step, the General Administration will also issue opinions with relevant departments to improve the consumption environment, launch the creation of a national demonstration city for assured consumption, give play to the role of traction and incitement in the overall creation of the city, and drive the consumption environment in various places to further upgrade.

Basic knowledge of e-commerce: introduction of supply chain products

With the development of e-commerce, many people know that a very important competitiveness of enterprises lies in the supply chain, but what is the supply chain? Most articles on the Internet talk about some concepts, which makes it difficult for practitioners to implement them. This paper will talk about the understanding of e-commerce supply chain based on the author’s own experience, and welcome all interested parties to exchange and learn together.

Baidu Encyclopedia tells us: "Around the core enterprises, through the control of information flow, logistics and capital flow, starting from purchasing raw materials, intermediate products and final products are made, and finally the products are delivered to consumers by the sales network. It is a functional network chain model that connects suppliers, manufacturers, distributors, retailers and end users as a whole. "

Simply put, it is the process of goods from [supplier] to [seller] to [demander]. Of course, there are many roles involved in this process, and these roles are interrelated and form a complex network model. An enterprise may play multiple roles in both supplier and seller, so the chain of supply chain will be shortened. Logistics, from [supplier] to [demander]; Capital flow from [demand side] to [supply side]; Information flow, various roles pass each other.

What is a good supply chain? My understanding is: better goods (quality and price), faster transportation, better service and better cost.

Most of the articles on the internet now make you feel particularly reasonable, as mentioned above, but after reading them, I still don’t know how to apply them to my products.

The design of e-commerce supply chain, the most important thing is based on business. There are many types of e-commerce business. Here, I will talk about my own understanding only for the most common business. There are many ways to classify e-commerce business. Here, we will explain e-commerce business from the perspective of commodity source, commodity sales and warehousing and distribution.

Source of goods: self-production, self-mining, investment promotion, etc. Self-production means that goods are produced by themselves, such as herbs; Self-mining refers to purchasing goods from suppliers, such as most of the goods of Netease koala; Merchants, merchants enter the platform for sale, such as Tmall.

Commodity sale: own platform, third-party platform, wholesale, etc. Own platform, refers to the development of their own platform to sell goods, such as Gegejia; Third-party platforms refer to opening stores for sale on third-party platforms, such as Tmall and JD.COM; Wholesale, the downstream of this business does not actually reach the consumer, and it may reach the consumer through other sellers many times, so it is listed separately, such as dolphin supply chain.

Warehouse delivery: Do you build your own warehouse and deliver the goods yourself?

Of course, most companies include the above businesses, such as Netease koala, and the sources of goods include self-mining and merchants’ settlement; Commodity sales include self-owned platforms and third-party platforms; Warehouse delivery, including self-built warehouses and cooperative warehouses, is the responsibility of third-party companies.

Let’s assume that the e-commerce business is as follows

Source of goods: self-mining;

Commodity sales: own platform;

Warehouse delivery: self-built warehouse, third-party company delivery.

Then the positive process of e-commerce supply chain products is roughly as follows:

  1. The supplier is the supplier, and the goods are originally in the supplier’s place;
  2. Enterprise system (ERP) establishes purchase orders through purchase plans, and collects goods from suppliers into its own warehouses;
  3. The warehouse system (WMS) manages the inventory of goods in the warehouse system through transport documents/receipt documents, associated purchase orders, or other warehousing methods;
  4. After the enterprise system (ERP) obtains the commodity information and inventory information, it transmits the commodity information to consumers through its own platform for commodity sales.
  5. After receiving the order information, the order system (OMS) processes the order (customer review, financial review, warehouse selection, opening and closing, etc.) and monitors the order. After the order is processed, push the order information to the corresponding warehouse; (The most direct experience of users to e-commerce enterprises is logistics, so the processing and monitoring of orders directly affect the user experience, including the "full link of orders" proposed by Tmall, which aims to improve the user experience here)
  6. After receiving the order information, WMS performs operations such as billing, sorting, inspection and delivery, and delivers the order to a third-party courier company for distribution.
  7. Goods reach consumers through express delivery.

There are several systems involved here. Let me explain the terms first:

  • ERPEnterprise Resource Planning, which mainly refers to the internal systems of the company, including procurement management, commodity management, marketing management, CRM, after-sales work order management, financial management, employee management, etc.
  • WMS: Warehouse Management System, which mainly refers to the system used inside the warehouse, including the management of warehousing, warehouse distribution and delivery (billing, picking, inspection, delivery, etc.).
  • OMS: Order Management System, which mainly refers to the operation and monitoring of orders, such as customer orders, financial review, warehouse selection, opening and closing orders, etc. Monitor and deal with all kinds of timeliness and anomalies of orders. OMS is also a part of ERP system conceptually. Because it is particularly important in the supply chain system, it is listed separately here.

Another common type of e-commerce business

Source of goods: merchants settle in;

Commodity sales: own platform;

Warehouse delivery: there is no self-built warehouse, and the third party company delivers the goods.

Then the positive process of e-commerce supply chain products is roughly as follows:

  1. As the supplier, the settled merchants initially have the goods there;
  2. The settled merchants release commodity information and manage commodity inventory through the merchant background system;
  3. Enterprise system (ERP) examines the commodity information of merchants, and manages and sells the commodities of merchants;
  4. After receiving the order information, the order system (OMS) processes the order (such as customer review, financial review, merchant selection, order splitting and order merging) and monitors the order. After the order is processed, push the order information to the corresponding merchant;
  5. The settled merchants get the order information through the merchant background system, and operate and deliver the order;
  6. Goods reach consumers.

An excellent e-commerce supply chain not only means that we can get good goods (quality and price) offline, but also requires the close and efficient cooperation of all the roles on the chain (suppliers, sellers, warehouses, etc.) and various online systems (ERP, OMS, WMS, TMS, merchant systems) in order to achieve faster distribution, better service and better cost. This should be the core of e-commerce enterprises.

E-commerce supply chain system is a complicated system. Today is the first day of 2017. Let’s write a big framework first, and strive to improve each part step by step this year. Welcome interested friends to communicate!

Oral: Zhang Liangsheng, researcher of Chinese Academy of Sciences: the first postgraduate exam in 1978.

[Editor’s note]What subjects were there in the college entrance examination 60 years ago? How was the postgraduate exam conducted 40 years ago? The Paper interviewed Mr. Zhang Liangsheng, a researcher at the Institute of High Energy Physics, Chinese Academy of Sciences, and asked him to talk about two "big exams" in his life and his experiences and anecdotes in high energy physics research.

Zhang Liangsheng was born in June 1939 in Wuxi, Jiangsu. He participated in the college entrance examination in 1957 and entered the nuclear physics major of Nankai University. In 1978, he was admitted to the first postgraduate after the resumption of college entrance examination, and entered the Institute of High Energy Physics of Chinese Academy of Sciences, where he studied under Professor Zhang Wenyu, the founder of high energy experimental physics in China. Mr. Zhang Liangsheng devoted his life to the experimental research of high-energy physics in China.

Zhang Liangsheng is being interviewed.

Learn with one heart

Our family was very poor before liberation. My father was an apprentice at the age of 13 and worked as a clerk in a grocery store. Eldest brother is also about 13 years old (as an apprentice); The second brother is a little older and became an apprentice at the age of 16. After liberation, my father spent some money on a small stall, selling some soy sauce, salt and so on. He wanted to get rich.

My father asked me to inherit his career and run a small stall after I graduated from primary school. He taught me how to purchase goods, how to keep accounts and how to use abacus. I said I wouldn’t do this, but I had to go to school. Finally, my father and I reached an agreement. He said that if you were admitted to Wuxi No.1 Middle School, you would go to school. If you failed, you would work with me. No.1 Middle School is a public school, and the quality is very good. It doesn’t cost any money to get into No.1 Middle School, and there are state grants. As a result, I was admitted, and my father said, then go to school. At this time, it was just liberated, and tuition was free. Moreover, I applied for a grant after I went to school and went to high school.

I study very hard in middle school, and I like to study hard at ordinary times. I read my brother’s middle school physics book in primary school and was very interested. Once a classmate pulled a roller to repair the playground. The roller got stuck in the pit and couldn’t be pulled. He asked me what to do. I said you turned it upside down, pulled it back, and then jerked it forward and rushed over. They did it according to my method.

I took the college entrance examination in 1957, which was the most difficult one before the "Cultural Revolution". I was very stuck, and I volunteered before the exam. I’m afraid I won’t get into Tsinghua Peking University, so I’m conservative and applied for Nankai University. When I was in high school, I chose science. I took seven courses in Chinese, mathematics, foreign languages, politics, physics, chemistry and biology in the college entrance examination, and I got 96 points in physics. If I applied for Peking University, I could get into it.

In 1957, Zhang Liangsheng was photographed when he graduated from high school.

I studied nuclear physics in the physics department of Nankai University for five years. At that time, universities were all five years. Graduated in 1962, then stayed in school to tutor the basic course of nuclear physics, and then came to Lanzhou University, where he was promoted from a teaching assistant to a lecturer.

Want to go to Lanzhou to do something.

On October 16, 1964, our country exploded the first atomic bomb. At that time, the Ministry of Higher Education had planned to concentrate on two places in the north to engage in nuclear physics and radiochemistry, one was the Department of Physics of Peking University, and the other was the Department of Modern Physics of Lanzhou University, because Lanzhou was in the northwest and close to the nuclear test site. The Ministry of Higher Education intends to move some majors in nuclear physics and radiochemistry from Nankai University and Shandong University to the Department of Modern Physics of Lanzhou University.

Nankai took active action. In the summer of 1965, all the teachers, students and equipment of nuclear physics and radiochemistry were moved to Lanzhou. In order to move these equipment, the Ministry of Railways also specially prepared a special train, and the whole train was loaded with instruments and equipment.

There are about 100 students and teachers in the two classes going to Nankai. When moving, let everyone go home first, and then go to Lanzhou to concentrate, so everyone will arrive in Lanzhou early and late. I arrived in Lanzhou on August 23rd, and I was the first one to arrive in Lanzhou. At that time, I was in a state of mind, hoping to see what Lanzhou was like, hoping to do something in Lanzhou.

At that time, the whole country was preparing for war, and Lanzhou University had professional knowledge and technical conditions. The Lanzhou Military Region hoped to equip the PLA with some equipment for detecting nuclear radiation. The two sides hit it off, and we helped them to make a device called "automatic gamma ray alarm device". After the nuclear explosion, the gamma rays would whir to a certain extent, and the response was not bad. Later, a "automatic gamma ray recorder" was further developed, which was a little more advanced. It will record the intensity of gamma rays after the nuclear explosion by itself, and it has a wide range. It has four gears and will automatically shift gears as a daily monitor in the chief’s room to see if the radiation exceeds the standard. Later, these two devices won four awards at the National Science Conference in 1978, one was the Science Conference Award, the other was the Ministry of Chemical Defense, the Gansu Provincial Science and Technology Progress Award, and the other was the Lanzhou Military Region Award.

The other is to participate in nuclear tests. I won’t say much about this, but I have to keep it a secret. At that time, I also went to the proving ground. The school sent two people, one was me, who was engaged in nuclear physics, and the other was engaged in radiochemistry, both of whom were from Nankai University. However, we didn’t wear radiation masks, long boots and lead clothes like others, and after finishing half a bucket of sweat, it wasn’t that bad. We just tested gamma rays in the house, which was still a certain distance from the central area of the nuclear explosion, and it wasn’t as hard as their first line.

I also went to factories and rural areas to attend classes while taking part in labor. At that time, I chose three teachers, and I was one of them. I took a class of students to Xi ‘an 262 Factory to "open a school", where I gave them technical lessons. After I came back, the factory sent people to Lanzhou and invited me to give lectures to the students of 721 University in their factory. 721 University was very common at that time, which was equivalent to an enterprise university. Because enterprises should have their own technical talents, in order to cultivate talents, they chose some workers from the factory, did not study full-time, and hired teachers from outside to respond to Chairman Mao’s "721 instruction" and learn to work, learn agriculture and learn the army.

The level of students of workers, peasants and soldiers is uneven, some don’t understand, some don’t have enough to eat, so we should take care of everyone when teaching and be relatively relaxed when graduating. Teachers are also urging teachers to learn, so I have never given up my major. Moreover, in the late period of the "Cultural Revolution", the atmosphere on campus began to love reading. There are also some old intellectual families. Although the state does not attach importance to it, there are still some wishes and practical actions for children to learn. There is a kind of person who always has a desire to pursue knowledge no matter what social environment.

I also keep a hope that one day the country will be normal, and it can’t go on like this forever. There has been no enrollment for ten years. What will the country do after that? How can we do it when everyone is illiterate? I think the normal enrollment of college entrance examination will be resumed one day.

The First Postgraduate Examination after the Cultural Revolution

At the beginning of 1978, I was taking part in a nuclear test in our country when I knew I wanted to recruit graduate students. There were many people who took part in the nuclear test that time, and everyone communicated with each other. I heard the news of recruiting graduate students, but I didn’t know it in detail. Because the national college entrance examination for undergraduates was resumed in 1977, it was not surprising at all to get the news of resuming postgraduate recruitment, which was expected.

The Admissions Office in Lanzhou is located in a school in the city. I learned that it is really necessary to recruit graduate students, and the age range has expanded to 40, and my age is also included. I am very happy and feel that I have finally had a chance after waiting for so many years. The recruitment method is basically the same, that is, the process of registration, written examination and re-examination.

I came back and prepared an inch of photos, so I went to register. When you register, you should give the photo to the Admissions Office. After that, it will be posted. I went to see it, and it has my name, so that the formal registration is successful. After I signed up, I got an admission ticket, which I still have.

Admission ticket

There is basically no time to review before the exam. On the one hand, I have to work, and on the other hand, I have two children to take care of. It is because of my physical skills in college and my interest to take the exam. After the "Cultural Revolution", the country was not ready for the first postgraduate exam, but just wanted to open it, so there was neither an exam outline nor exam materials, and they were all in a hurry.

The formal exam is also in the school where I signed up. It seems that there is only one test center in Lanzhou, and there are only twenty or thirty people in an examination room. I am one of the oldest in it. I remember that my position is next to the north wall, the penultimate row. The exam is a table for one person, which is relatively apart to prevent looking at each other. There are two or three invigilators, the admission ticket is on the table, and the invigilators should check the photos so as not to be replaced by others.

In the middle of the exam, everyone is generally more disciplined and cherish this opportunity. During the "Cultural Revolution", some people basically lost everything they studied and did something else. Even if you asked him to take the exam, he didn’t have the heart to take it. However, there are still a small number of people who haven’t left their studies for so many years and hope to resume the exam one day. These people who took the exam basically belong to this category, that is, they usually study hard and have some foundations, so it is not easy to have such an opportunity, so they didn’t cheat in the exam.

I’m not too nervous during the exam. I think I’ll do whatever I get in the exam. I want to keep my mood relaxed. At that time, I took three exams, one political course, one foreign language course and one specialized course. My specialized course was high-energy physics, and I got 95 points.

I felt very uncomfortable when I took the physics exam. I still remember the general content, saying that there was a ball, and particles were emitted from the surface of the ball, and at the same time the ball fell. I asked how long it would take for the ball to fall in a vacuum. I think the conditions of this question are confused. If particles are sprayed in one direction, just like jets or rockets, they are different from spraying in all directions. If particles are sprayed in all directions, it is necessary to know how big, how much and how fast the particles are, and the results are different. These conditions were not given, so I simplified it at that time. After the exam, I always thought that there was something wrong with this question, so I wrote a letter to Gao Neng Institute, in which I wrote my calculations and some ideas. When I went to the High Energy Institute for a second interview, I heard that this question was cancelled. They might think it was reasonable after reading my letter. This question was simply left out, so I asked where I was wrong. They checked it for me and said that I didn’t have a particularly big mistake, that is, one point was deducted. Anyway, there were some omissions. In some places, the answer was incomplete, not a big problem, and finally I got 95 points.

The political examination is mainly about current events, such as the destruction of the Gang of Four, which brought the national economy to the brink of collapse. It was mainly based on the accumulation of reading newspapers and listening to the radio at ordinary times. At that time, everyone paid close attention to some political trends and knew about general state affairs.

There are some questions in the English exam that are similar to Shakespeare’s translation, and there are no textbooks, that is, I always read some English materials, and I go to attend the English class at school, and I read some physics journals in English, so I have never abandoned them. Besides, it was not difficult to do the first exam in good conscience.

After the written test, I wasn’t sure whether I could get in. At that time, the institute of high energy recruited 20 people, but hundreds of people signed up and later told me to go to Beijing for a second interview. At this time, I was a little sure in my heart. At that time, it happened that my wife was steaming steamed buns. I grabbed two steamed buns and left with a bag of paper, because the two steamed buns were still hot and covered, and I had diarrhea after eating them.

During the interview, I was asked why I took the postgraduate exam, why I took the high-quality college exam, and what I had done before. I chose the high-energy physics major of Chinese Academy of Sciences. One reason is that after I stayed in Nankai University, I was sent to the Institute of High Energy for a period of time. After that, I hope to go to the Institute of High Energy in the future. Another reason is that after the "Cultural Revolution", Deng Xiaoping made up his mind to grasp high-energy physics, and found more than 100 high-energy physics students from all over the country, and concentrated on recruiting them to Beijing, which was unprecedented in history, because it was very difficult to enter Beijing, but later I couldn’t be directly transferred to Beijing, so I had to enter the Institute of High Energy Studies of the Chinese Academy of Sciences by examination. I just like physics and want to study it all my life.

Later, someone asked me if you would like to be a graduate student of Director Zhang Wenyu, and I said of course I would. Zhang Wenyu is the first director of the Institute of High Energy Physics, and he has done pioneering work in muon atomic physics in the world. When Li Zhengdao and Yang Zhenning won the Nobel Prize, the state sent him to Sweden to do their work, and Yang Zhenning also publicly stated that Zhang Wenyu was his mentor.

Shortly after the interview, I received a letter saying that you have been officially admitted as a graduate student of Professor Zhang Wenyu. I was very excited after receiving the letter. I used to hear and see it in the illustrated newspaper on the radio. Now the relationship is so close, I went to the reference room of our department to find the relevant pictures. People’s Pictorial has a picture of Mr. Zhang Wenyu. I studied it for a long time and thought about it. I was very happy at that time.

In the summer of 1981, Zhang Liangsheng and his tutor Professor Zhang Wenyu (right) took a group photo in front of the main building of High Energy Institute.

When Lanzhou University took the exam as a lecturer, five people were admitted to each applicant. On September 29th, Lanzhou University held a school committee, which was equivalent to the highest-level meeting. At the meeting, it was discussed that five people were admitted to graduate schools, and Lanzhou University, as a school, would not let people go. Finally, it was considered that this was a major national policy and agreed to let people go and study with pay.

I joined the work in 1962, and by 1978, I had been waiting for 16 years. I was 39 years old when I took the exam. This was a very rare opportunity, and I seized it. By the second year, I was stuck.

Graduate student with Mr. Zhang Wenyu

After I arrived in Beijing, I studied basic courses first. I was old and my brain was failing. It was very difficult to learn. Other students were playing outside, so I studied in the house. People came back to see me studying there after playing, always sitting, always studying.

After finishing the basic course, I did my graduation thesis. At that time, there was no high-energy accelerator in our country, so it was not necessary to do high-energy physics experiments. Mr. Zhang Wenyu suggested that I do the work of high-energy detector-multi-wire detector, which is to detect the tracks of microscopic particles invisible to the naked eye.

Professor Zhang Wenyu particularly emphasized the need to do experiments. He said that "experiments are the basis of theory and the source of knowledge". He himself published an article in People’s Daily stressing the importance of experiments. Don’t sit there all day dreaming and don’t do practical things. He particularly emphasized this point. According to Zhang Wenyu’s teaching, I started from the basic things, including how to punch holes, how to draw wires, how to glue, how to package, how to ventilate, how to measure, how to record data, and finally analyze and write papers. These are all done by myself, and the experimental results are published in High Energy Physics and Nuclear Physics.

On this basis, I also quantitatively explained a new international experimental result, that is, the experimental group directed by Professor Xia Pake, who won the Nobel Prize in Physics in 1992, used the "multi-step avalanche chamber" filled with argon gas to let a high-intensity charged particle beam pass through it and make it run at a high counting rate, thus obtaining the breakdown data of the "multi-step avalanche chamber" when it was running at a high counting rate. They didn’t give a quantitative explanation for the result themselves, but only gave a qualitative explanation. I have a different view, so I established an equation for quantitative calculation. The calculation results confirmed my assumption that the decay life of the substances accumulated near the anode wire in the multi-step avalanche chamber is consistent with the metastable life of argon, which shows that the metastable state of argon plays a decisive role. After my explanation was published at home and abroad, an experimental group of Kyushu University in Japan made an experiment by experts to test whether my explanation was reasonable or that of Professor M.Atac in the United States. The experimental results supported my explanation and called it "Zhang Model".

In 1992, at CERN, Zhang Liangsheng (left) congratulated Xia Pake (right), winner of the 1992 Nobel Prize in Physics.

After the thesis defense, everyone thought that my level was higher than that of the master’s degree. An international experimental result was not explained correctly. I explained it quantitatively, but it was not appropriate to give it to my doctor directly, because our high-energy institute trained experimental high-energy physics, and I engaged in detectors, which are also in the category of high-energy physics, but there are still some differences when we talk about it carefully. The institute wanted me to continue my PhD, but my wife and I were separated, and I still had a child at that time. This situation made me stay for a few more years, which was really not good. I told the company that it was difficult to separate at home. So he graduated in 1981 and assigned work according to his master’s degree.

Dedicated to the research of high-energy physics all his life.

There have been many schemes or ideas for high-energy accelerators in China. There is a saying called "eight ups and seven downs", one of which was presided over by Premier Zhou during the Cultural Revolution. The scheme was put forward, and all the money was available, and it was ready to be done. As a result, the Gang of Four made trouble and failed to make it. It was called "eight ups and seven downs".

In 1978, Deng Xiaoping made up his mind to do it, and put forward a plan, namely the ring accelerator, which made a name for itself. After exploring the terrain in the Ming Tombs, he dismounted. The reason for dismounting this time was that the pace was too big and the national economy could not support it.

Later, Professor Li Zhengdao proposed an electron-positron collider to accelerate positrons and negative electrons respectively and focus them on one point for collision. Of course, the collision is worse than hitting a static target, and the electron itself is relatively small in mass, which is relatively easy to do. Everyone agrees to use the electron collision method. Finally, this project was completed. The state awarded a grand prize and held an award ceremony in Huairentang, Zhongnanhai. I was one of the winners in it, and the certificate was signed by Premier Li Peng at that time.

In 1984, Professor Ding Zhaozhong came to China to recruit students to engage in high-energy physics experiments in the Mark-Jay Group in West Germany. Ten people were found in the high-energy institute and asked to review before taking the exam. Two of them did not take the exam, and only one of the remaining eight people was admitted. Later, I recruited another batch, and this time I was recruited, and I was admitted alone; Later, I took the exam twice, and two more people were admitted. Ding Zhaozhong took several of our admitted students to Beijing Hotel for an interview, which was mainly about high-energy experimental physics. He asked me about "proton decay", and I replied that according to the "grand unification" theory, "baryon number" and "lepton number" are no longer conserved quantities, so protons can decay. Only by answering this sentence, he felt satisfied. He asked his mind to be clear and not verbose. The more you talk, the more confused you are, which means that you don’t understand. Simply point out the most critical points and he will know that you know the problem. So I went to West Germany in 1985.

In 1985, Zhang Liangsheng (first from the right) took a group photo with Ding Zhaozhong (second from the right) in the MARK-J group.

At the end of 1992, I was once again sent to work in a European nuclear research center for more than a year. After I came back, I worked in a high-energy institute until I retired. After I finished my studies, I made a contribution to my country.

High-energy physics is widely used in reality, and the Internet is one of them. At CERN, there was a group mainly engaged in the transmission of high-energy data. On this basis, a concept of high-energy network was gradually developed, and this concept gradually became the Internet. With the advice and help of Professor Li Zhengdao, the Internet established by our country with foreign countries through the Institute of High Energy is also for the purpose of transmitting high-energy experimental data. With this foundation, our country has invested heavily in developing the Internet, and China has a large population, a large base and a scale effect, so the Internet has developed rapidly in China, which is still very advanced internationally. Our country’s high-energy physics is now in the international leading position in some aspects.

In retrospect, taking the first postgraduate exam after the resumption of the college entrance examination was an opportunity for me to change my fate, and it was also the only opportunity for many students after ten years of interruption of the exam during the Cultural Revolution. Ten years of "Cultural Revolution", ten years of fault, talent training was abandoned in the "Cultural Revolution". Restoring the college entrance examination made everyone feel that there was hope and a way. They could gain a sense of accomplishment through their own efforts and have their own glory in it at a certain stage. This is a good thing that benefits the country and the people, and it is a major move after the country is on the right track.

If a country wants to stand on the top of the world, it must have world-class leading talents. Everything in exam-oriented education is to cope with exams, cramming and memorizing, which stifles learning enthusiasm. We should encourage everyone to study hard, have their own opinions, give full play to their strengths, be active and creative, have a strong thirst for knowledge and interest, and don’t become an examination machine.
