  "It is better to take responsibility for cyberspace and the digital economy than to worry about it. In recent years, almost all over the world are worried about the new technology era and technology, worried that machines will take away job opportunities, worried that machines will control human beings, and worried that human beings will be destroyed in their greatest inventions. In fact, the new technology is not to make people unemployed, but to make people do more valuable things, to make people not repeat themselves, but to innovate, so that their work can further evolve. I believe that machines will make people’s work more dignified, valuable and creative. "

May knowledge illuminate everyone and discover a bigger world together. "

  Liu Qiangdong, CEO of JD.COM: drones solve the last mile problem of rural logistics

  Photography/Xinhua News Agency reporter Huang Zongzhi

  "Logistics leads to poorer, more remote and backward areas, but the value of industrial products that consumers have to pay is much higher than that of rich areas such as Beijing and Shanghai. At the same time, because of the high logistics cost, a large number of high-quality agricultural products can’t leave the village. After they come out, they arrive in Beijing and Shanghai, and the prices are too high for consumers to consume. It took us 10 years to establish a huge logistics network covering the whole country. We are still investing a lot of money in developing the latest logistics technology, the most important of which is the drone, which is to solve the problem of the last mile of rural logistics. "

Li Keqiang cultivates "double innovation ecosystem": China is becoming a global "maker paradise"

  Giving up a high-paying job in San Francisco and starting a business in Shenzhen, China, Canadian Lawrence’s choice won the support of many friends around him.

  "They are very envious when they know that I am coming to China, because they think that China has the most imaginative market at present." Lawrence said, "The atmosphere of entrepreneurial innovation in China is very strong, and you have unlimited possibilities to achieve what you want to do."

  In fact, more and more overseas "makers" choose to come to China just like Lawrence, and what attracts them is the "mass entrepreneurship and innovation" advocated by Premier China.

  Go to China to start a business! ",the British" Financial Times "website that noticed this phenomenon reported on this topic. "Economist" magazine also said: "Shanzhai merchants are gone, and innovators are coming!" Taking Shenzhen as an example, the report points out that it is attracting all kinds of entrepreneurs around the world who are trying to make new products in new ways. Invention and innovation are transforming the whole Pearl River Delta into an advanced manufacturing cluster.

  Chen Siyu, Commercial Officer of the Swedish Consulate General in Shanghai, said that Sweden is a "country of innovation", and there are about 20,000 start-ups with a total population of 10 million. However, in recent years, Swedish entrepreneurs have come to China one after another, because most of them have to rely on their own development to start their own businesses in Sweden. In China, the government has invested a lot of manpower, material resources and financial resources to support entrepreneurial innovation, and with a relatively complete industrial chain in all walks of life, it is called "maker’s paradise".

  "internet plus" faces the whole world, and foreigners find new opportunities in China.

  "China is vigorously promoting ‘ Internet plus & rsquo; This is itself global. " On June 28th, Premier Li Keqiang’s statement during the dialogue and exchange with the representatives of international business circles attending the Davos Forum in the summer of 2017 was regarded as a "strong signal" released to foreign businessmen.

  China’s booming "internet plus" and consumption upgrading have already made more and more foreigners see the business opportunities of starting new businesses. And China’s superior "double innovation" environment is making their entrepreneurial dream come true.

  German Alberton founded Zanado Company in China, which not only provided online travel booking service, but also opened an offline VR experience store, bringing travelers a 360-degree virtual travel experience. Alberton said that China people are willing to "try early", while it may take 10 years for the United States and Europe to accept these.

  Lan Jili, founder of Vitas, a game and entertainment production company, believes that the China government is very friendly to entrepreneurs, and "we have the opportunity to bring new technologies into China". Jared, founder of R2Games, said: "In the era of mobile Internet, it is safe to say that China is ahead of Americans in this area. For a global Internet company, the opportunity is now in China. It won’t happen anywhere else, it can only happen here. "

  It takes two years in the United States and only half a year in China. China is the first choice for hardware entrepreneurship.

  The Economist also found that China is rewriting another rule, that is, embracing open innovation. Taking Shenzhen as an example, the report points out that China’s open innovators are not secretive, but are committed to providing solutions for the public. Analysts pointed out that the "double-innovation ecosystem" formed by the integration of China’s policy support and complete industrial chain is unmatched by many other countries.

  The world’s thinnest folding full-color touch screen produced by Rouyu Technology Co., Ltd. needs a lot of "integrated innovation" and "maker" ecosystems from early research to finished products. Bill Liu, the founder of the company, said that when he set out to establish Rouyu, it was clear that the company had to establish itself in Shenzhen to be successful.

  Jenny Lee, an investor in the hardware industry and a partner of GGV capital (GGV), said that in Shenzhen, it takes only half a year for a hardware startup to turn a concept into a product, which usually takes two years in the United States. When Revols, a Canadian "maker", tried to develop economical customized headphones in Montreal, he found that things there were slow and expensive. After he moved the company to Shenzhen, he quickly made a prototype and the product has been put into production.

  "China’s already blazing pace of innovation is still accelerating!" The Economist said. Many multinational companies have set up "observation posts" in China to pay close attention to the latest trends here. Shenzhen, China has become one of the global innovation centers of intelligent manufacturing, and is favored by all kinds of "makers".

  Scientific research results can land, and scientists bring "black technology"

  Many foreign "makers" said that overseas, many "black technologies" are only academic achievements, but coming to China, which is full of possibilities, can make it a reality.

  Professor Wusi Kaelte, an academician of the European Academy of Sciences, believes that China’s government and industry are actively promoting the application of artificial intelligence (AI) and big data, and starting a business in China is the best opportunity for its research results to land. The scientist in the field of artificial intelligence set up the Institute of Know Infinite Artificial Intelligence in Beijing in May this year, and cooperated with JD.COM, BOE and other enterprises to help China enterprises build an innovative ecosystem in the fields of AI visual recognition and translation.

  Liu Huijun, dean of the School of Electronic Engineering of the Korean Academy of Sciences, also settled in Dongguan with the whole team. Its "black technology" AI-AR smart glasses will be mass-produced locally, which can realize remote precision maintenance of automobiles and airplanes. As long as the staff wear this kind of smart glasses, they can see the maintenance scene and remotely maintain it. In the process, they can also see the analysis of the fault made by AI behind the glasses.

  In the article calling for starting a business in China, the Financial Times website wrote that overseas entrepreneurs who have successfully started a business in China have pointed out a new path for young people who are interested in starting a business.

  As Premier Li Keqiang said: "Our entrepreneurial innovation is open. We should sum up experience and attract enterprises from more countries to come with capital, technology and talents, so as to achieve a win-win situation in cooperation." (Beijing News special correspondent Mu Yi)

70 years of experience, 70 years of quality | Celebrate the 70th anniversary of the establishment of Kouzi Wine Industry!

  Chongqing morning post reporter Liu Bo reports.

  Is natural mineral water really natural and pollution-free? The more expensive the mineral water, the better the quality? Recently, chongqing morning post, together with Consumer Report magazine, sent 12 kinds of packaged drinking water of 10 brands to an authoritative third-party testing agency for inspection.

  Among them, there are 7 kinds of natural mineral water including Nongfu Spring, Kunlun Mountain, 5100 Tibet Glacier, Jingtian Baisui Mountain, Uni-President alkaqua, France perrier, Danone Yili, 4 kinds of infant water including Nongfu Spring, Jurassic, Bay Blue and Santa Anna, and one kind of natural water of Nongfu Spring.

  We will tell you that the quality of mineral water is not directly proportional to the selling price by comparing the results of N1 index, TOC, total phosphorus, sodium, taste index and total number of colonies.

  Evaluation report 1 is pollution-free.

  The water in 1.5 yuan is better than that in 27 yuan.

  In many people’s minds, the sign of good water is "natural and pollution-free". Therefore, we first determined the N1 index, total phosphorus and total organic carbon (TOC) of 12 kinds of packaged drinking water. According to WHO regulations, the sum of the ratio of nitrate measured value to standard value and the ratio of nitrite measured value to standard value in water should be less than or equal to 1.

  "A large number of data surveys have found that the total amount of nitrate nitrogen in natural high-quality mineral water and natural mountain spring water in nature is less than 0.5." Professor Li Fuxing, Director of Beijing Public Health Drinking Water Research Institute, introduced.

  "So we take 0.5 as the critical value of’ good water’. We named this formula N1 index. " Li Fuxing said that the conversion formula of N1 index is N1= nitrate measured value/standard value+nitrite measured value/standard value. The greater the value of N1, the more seriously the water quality of the water source is polluted.

  The results showed that the N1 index of 12 kinds of packaged drinking water was below 0.5, which met the requirements of WHO for good water. In addition, no total phosphorus and total organic carbon were detected in all the packaged drinking water, indicating that the water source was less polluted.

  The N1 index of Bay Blue natural mineral water from New Zealand was only 0.021, while the N1 index of Jurassic natural mineral water reached 0.376.

  The N1 index of Danone Yili’s drinking natural mineral water source, which is only sold in 1.5 yuan, ranks second, which is more pollution-free than perrier natural mineral water sold in 27 yuan.

  Evaluation Report 2 Taste

  Water with the right mineral content is really "a little sweet"

  The slogan "Nongfu Spring is a little sweet" has made many people begin to notice the taste of packaged drinking water. However, there are no relevant standards and quantitative tools for evaluating the taste of packaged drinking water.

  After investigating and analyzing the mineral components in tap water and drinks in the world and Japan, the scholars of Osaka University in Japan think that the taste index is closely related to five components: calcium, potassium, silica, magnesium and sulfate, and put forward a formula for evaluating the taste of drinking water: the taste index oi = (Ca2++K++SiO2)/(Mg2++SO4 2-) ≥ 2.

  According to the formula, the taste of water is positively correlated with the taste index. The higher the value, the sweeter the water is, and "2" is the critical value of taste.

  "The higher the content of calcium ions, the thicker the taste of water. A proper amount of potassium ions can make water sweeter, and silica is also conducive to improving the taste of water. Too high content of magnesium ions and sulfate will make water bitter and astringent. Only when the contents of these five ions are in a relatively balanced range will the water become sweet, thick and delicious. " Zhao Feihong, director of the Drinking Water Professional Committee of Beijing Health Protection Association, explained.

  According to the formula of taste index, we measured the taste of 12 kinds of packaged drinking water. The taste index of 9 kinds of water is higher than 2, and the best taste is Danone Yili drinking natural mineral water and Jingtian Baisuishan natural mineral water, with the taste indexes of 16.35 and 14.07 respectively.

  The taste index of Jurassic natural mineral water (infant water) was 0.31, and that of 5100 Tibetan glaciers was 1.43, which did not meet the minimum recommended index of taste index.

  Evaluation Report 3 Sodium Content

  Three kinds of water should not be drunk by special people for a long time.

  Scientific research shows that excessive salt intake is easy to cause diseases such as hypertension, myocardial infarction and cancer. The main component of salt is sodium chloride, so controlling salt intake is actually controlling sodium intake.

  "For special people, such as infants, the elderly, hypertensive patients, and people with low immunity, the sodium content in drinking water should not exceed 20mg/L. Only water with sodium content below 20 mg/L can be called low-sodium water." Professor Li Fuxing, director of Beijing Public Health Drinking Water Research Institute, said.

  After testing, the sodium content of 9 of the 12 kinds of packaged drinking water sent for inspection is lower than 20mg/L, of which the sodium content of natural mineral water of Bay Blue is only 1.32 mg/L..

  The sodium content of Jurassic, 5100 Tibet Glacier and Kunlun Mountain mineral water was higher than 20mg/L, among which the sodium content of Jurassic drinking natural mineral water reached 154 mg/L. For special people, if they drink it regularly, it will have a certain impact on their health.

  Evaluation report 4 Total number of colonies

  Is infant water a concept?

  In recent years, water under the banner of "mother and baby water" and "baby water" has quietly become popular in the market. However, in China, there is no relevant standard for such new concept aquatic products. Judging from the current market situation, the concept of "sterility" is the mainstay of most infant water. So, is "sterility" reliable?

  We specially sent four kinds of infant water, including Nongfu Spring drinking natural water (suitable for infants), Italian Santa Ana baby mineral water, Bay Blue natural mineral water and Jurassic drinking natural mineral water, and compared two kinds of packaged drinking water of Nongfu Spring within the brand.

  In fact, there are no restrictions on the total number of colonies in the existing national drinking water standards GB 8537-2008 Drinking Natural Mineral Water and GB19298-2014 Packaging Drinking Water. The only requirement for the total number of colonies is GB5749-2006 Hygienic Standard for Drinking Water, with a limit of 100cfu/ml.

  According to the test results, the total number of colonies in Santa Ana baby mineral water in Italy is less than 1cfu/ml. The total number of colonies in Bay Blue and Jurassic reached 176cfu/ml and 1900cfu/ml respectively.

  Interestingly, compared with the products in Nongfu Spring brand, the total number of colonies in natural water and natural water specially marked for infants and young children is less than 1cfu/ml. In other words, before Nongfu Spring introduced the concept of "aseptic" infant water, the products had been "aseptic".

State Administration of Radio, Film and Television: China’s game market earns nearly 100 billion yuan in half a year, 4 times the total box office of movies.

In the penalty shootout, Xin Feng missed the penalty, and the northern team beat the southern team 9-8 (with a total score of 16-15) to win.



  This is the fourth time that the China Football Professional League has hosted the Star Tournament. In 1994 and 1995, the North-South Star Tournament was held at the beginning of League A, but since then, this grand ceremony of China football was interrupted. Until last season, the Football Association held the first all-star match in the history of the Super League in Jinan. This year is the second all-star match of the Super League, and the powerful northern team is even more shining. At the same time, various awards of this year’s league will be awarded today.

  Before the competition, the China Football Association and sponsors held a donation ceremony to the Soong Ching Ling Foundation of China, and donated 800,000 yuan to the latter. The game was kicked off by the southern team, and the northern team scored in the first minute. Li Jinyu broke through on the right to the bottom line and returned to the middle road.

Because it is raining in Shanghai, the field is slippery, which affects the mutual communication and cooperation between the players. In the 21st minute, the Southern Team expanded the score again. Zou Yougen passed the ball to the front of the goal from the left in the restricted area. Rooney didn’t get greedy and continued to pass the ball back to the former.

  The backward northern team stepped up their offensive. In the 34th minute, Du Zhenyu stopped the ball in front of the restricted area, and volley and the goalkeeper punched the ball. This shot was very wonderful. Two minutes later, the Southern team expanded its lead, and Wang Yun passed the ball to Li Yan at the bottom line on the right.

In the 41st minute, the southern team organized an attack in the frontcourt, and Li Yan’s shot in front of the restricted area was higher than the crossbar. In the 43rd minute, the northern team got a chance on the left, and Zhikov made a high-quality cross to the goal. Unfortunately, Qu Bo’s header was slightly higher than the crossbar.

The ball was saved by the goalkeeper, and Dong Wang’s supplementary shot hit the defender out of the bottom line. Then the northern team seized the opportunity. Tao Wei faced the defense in front of the restricted area and dodged the empty shot. The ball entered the door against the far post, and the score became 6-6. In the 74th minute, the northern team made a quick counterattack. Wang Yun made a wonderful pass from the front of the restricted area to the back point, and Yang Lin’s header was first cleared. In the 78th minute, the Southern team expanded the score again. Sun Xiang made an assist from the left and made a cross to the frontcourt. Rooney grabbed a header in front of the door and the score became 7-6. Then Rooney once again showed his football talent, and an imaginative shot almost broke the door again. In the 82nd minute, the Northern Team equalized the score, and Tao Wei returned to the middle from the left. Zhao Junzhe took the ball with two steps and shot with his right foot. The ball crossed the goalkeeper and fell into the net, and the score became 7-7.

  In the penalty shootout, Diego first volleyed the goal, and Sun Xiang’s powerful long-range shot equalized the score for the South Team. In the second round of penalty, Tao Wei deceived the goalkeeper and sent the ball into the net. Wang Yun’s very tricky shot made the goalkeeper helpless. In the third round, Zhang Yaokun scored a goal and Lu Feng equalized for the southern team; In the fourth round, Dong Wang took the lead in sending the ball into the goal, and Rooney also easily broke the goal; In the fifth round, Du Zhenyu made a strong long-range goal, and Ma Cheng’s shot deceived the goalkeeper.

It became the number one hot spot after class overnight. How long can Tenghahe last?

Reporter Han Bing reports Going out at home in the League Cup is not a big deal, but losing more than 3 goals at home in a row, the worst record of losing at home in 61 years, is a key node that may push Tenghahe’s fate from quantitative change to qualitative change. Although Manchester United did not consider changing coaches when talking to the media, the act of making a statement itself has already made the outside world smell dangerous.

The 0-3 defeat against Newcastle United activated a series of dazzling shame records: half of the top 10 home games of the season were lost, the worst since the 1930/31 season; Lost 8 of the first 15 games, the worst since the 1962/63 season; There is also the highest loss rate (53%) in 90 years, which is not counting the previous 12 records of losing, conceding and losing in a row. The patience with Tenghahe is constantly consumed in this ever-increasing shame record, and the distance is getting closer and closer to being completely exhausted …

After the game, Tenghahe continued to complete the familiar "reversal" at the press conference, but his odds after class jumped to the second place in the Premier League within 24 hours after the game (odds of 3), second only to Sheffield United coach Hejin Barton (odds of 5/3) who scored only 1 point in 10 rounds. Chelsea coach Pochettino, who burns more money, has fewer events and fewer points, ranks fifth (odds are 17), which is much safer than Tenghah. In the early morning of Beijing time, just after Manchester United officially made a statement that it was not considered to change coaches, Tenghahe’s odds of class dismissal rose to the top of the Premier League (11/10), surpassing Hutchinson Barton (5/4), and Pochettino was even safer (20)! Overnight, Tenghahe entered the "extremely dangerous" zone from the "safe" position.

Since ancient times, there have been few gifts in the snow, and there have never been many people who have fallen into the rain. Tenghahe stressed that last season’s Carling Cup proved that he could turn the tide, but media such as Manchester Evening News and celebrities such as Neville made it clear that the Dutch coach had lost the support of the dressing room and it was only a matter of time before class was over. This season’s scandal-ridden dressing room of the Red Devils, after the turmoil of Sancho and Anthony, now players have completely lost confidence in Tenghahe himself. As early as after the Manchester derby, the British media revealed that players questioned Tenghahe’s tactics, including letting Lindelov, who is not good at wingers, play left-back, and Anthony, who is better at wingers, was not the first choice.

Tenghahe’s tough approach has also attracted the disgust of most players. Punishing Sancho is an example. After the Manchester derby, Tenghahe forced Manchester United players to stay to witness the celebration of Manchester City players and fans, canceled the original holiday and added extra homework, which was considered as disrespect for the players. The extra homework is to let the players watch the video edited by the coaching staff for themselves, which points out the mistakes made by the players. This kind of practice, like punishing primary school students, makes the stars feel "humiliated". The first person who didn’t buy it was Rachford. On the night after the derby, the Manchester United winger held a party in the nightclub until 3: 30 in the morning. At least for now, Tenghahe hasn’t given him a ticket.

Neville’s hint on the social media account is almost explicit: "We have seen such a situation before, we know how it ends, and we have had enough." Former Tottenham midfielder O ‘Hara also stressed: Manchester United is in chaos from top to bottom, the players don’t care about winning or losing, and the coach has lost the support of the players. This is similar to Neville’s definition of Tenghahe and Manchester United. Neville emphasized that both rivals of Manchester United have professional sports departments, but Manchester United doesn’t even have Sports director. In addition, after driving away Cristiano Ronaldo last year, Manchester United announced that it would consider new strategic choices, but there is still no clear direction today, which also makes Manchester United players feel insecure.

Tenghahe’s fate has changed from how to turn things around to when to finish class. The British media began to calculate the cost (15 million pounds) of firing Tenghahe for Manchester United. After Ferguson retired, this figure tied for the highest among the fired coaches. However, it has just been announced that last season’s revenue was as high as 640 million pounds, which is completely affordable for Manchester United, which set a new record for Premier League clubs. In addition, the media has even listed a succession candidate list for Manchester United: emeri of Aston Villa, Eddie Howe of Newcastle United, De Zerbi of Brighton, as well as the laid-off Zidane and the hot Bayer Leverkusen coach Alonso.

Different from last season, Manchester United’s dressing room is not only separated from Germany, but also the injury crisis has not improved. Casemiro’s new injury continues to weaken Manchester United’s already unbearable defensive end. Tenghahe wants to be what he calls a "fighter" and unite with the players to fight together, but he must first fully implement his tactics through the players-unfortunately, this is also the most difficult thing to do at present.

In order to save the situation, the British media revealed that Tenghahe would have a one-on-one conversation with Manchester United players to understand the situation and eliminate barriers. However, there is not much time left for Tenghahe, and the international competition day in November may be his last chance to breathe. At the end of November, Manchester United will play Galatasaray, Newcastle United, Chelsea and Bayern at home, and then Liverpool. How long can Tenghah last? It’s a good prize-winning quiz.

The maximum flow rate is 2180 cubic meters per second! Overwarning floods occurred in 84 rivers in 15 provinces in China.

  Cctv newsIn the past few days, many places in China have suffered from heavy rainfall. Floods exceeding the police occurred in 84 rivers in 15 provinces (autonomous regions and municipalities) in the northwest, Huanghuai, Jianghuai, Jiangnan and Southwest China.

China launches a super satellite: high-speed Internet access will be realized on the plane’s high-speed rail.

  CCTV News:The geostationary communication satellite represents the development level of a country’s satellite communication. It is an important resource that constitutes the foundation of the information superhighway and an important embodiment of a country’s comprehensive strength and technical level.

  People who often travel in China know that mobile phones and notebooks can’t get on the Internet on flying planes and ocean-going ships. Similarly, on high-speed high-speed trains, mobile phone signals are intermittent. However, with the development of a new generation of communication satellites in China, full coverage of online chatting, ocean-going video entertainment and remote mountain signals will become a reality.

  China’s independent research and development technology breaks the monopoly of foreign air communication

  Maritime video will no longer be a dream.

  On April 12, 2017, China successfully launched the Shijian-13 satellite in xichang satellite launch center using the long march 3b. After completing the on-orbit test, the satellite was named Zhongxing-16.This is the first Qualcomm communication satellite in China, with a total communication capacity of over 20G, which truly realizes the broadband application of autonomous communication satellites.

  Zhang Wei, Senior Engineer of the Fifth Academy of Aerospace Science and Technology Group:The development of Qualcomm measurement technology represents that we are now on the ground, and you can use our satellite to realize video. Originally, only one voice communication function can be realized. Now we can video, so there is still a great application direction, that is, our aircraft. This is the first time that China has used Ka-band broadband communication technology on communication satellites.

  Satellite capacity is actually like a highway. The original C-band and Ku-band capacity of communication satellites can only accommodate two cars at the same time, and the cargo they can carry, that is, information and data, is limited. However, the capacity of Ka-band satellite is much larger, it can drive 10 or more cars on the road at the same time, and the amount of information and data it can carry far exceeds that of other frequency bands.The breakthrough of this technology means that broadband internet access can be realized anytime and anywhere through communication satellites in the future, especially in areas that cannot be covered by ground communication networks, as well as on aircraft, high-speed rail, ships and other means of transportation.

  Zhang Wei:Now everyone on the plane knows that communication can’t be realized. After the technology of HTS (Qualcomm Communication Satellite) is popularized in the future, we can also realize our communication on the plane based on satellites, including high-speed rail, ships and so on. HTS is a very popular application direction.

  Zhang Wei told reporters that relying on Qualcomm’s satellite communication technology, a satellite broadband communication network will be built in the future. By then, no matter whether you are in an airplane at an altitude of 10,000 meters, a high-speed high-speed train, or a ship in the vast sea, or a deserted desert, deep mountain or island, you can browse the network and make video calls at high speed.

  At present, the Fifth Academy of Aerospace Science and Technology Group has developed satellite mobile communication terminal products for outdoor, high-speed rail, ships and other aspects based on the Qualcomm satellite of Zhongxing 16. The original satellite communication terminals, limited by satellite design, are relatively large in size, and are generally installed on buildings or large vehicles.Now, relying on Qualcomm satellite, the terminal receiving device of communication satellite can be miniaturized, and ordinary household SUV can be installed.Zhang Ge, a senior engineer of the Fifth Academy of Aerospace Science and Technology Group, demonstrated a portable satellite broadband communication system for reporters. This system has the function of one key to the satellite, and can quickly connect the network when the ground communication network is damaged or interrupted in the earthquake-stricken area.

  In addition to this portable satellite broadband communication system, the team led by Zhang Ge is still developing satellite broadband communication systems for high-speed trains and ocean-going ships.

  Zhang Ge, Senior Engineer of the Fifth Academy of Aerospace Science and Technology Group:At present, our equipment supports more than 500 people, that is, if you install such a device on a luxury oil tanker, all the people on board can access the Internet directly via satellite by taking your ordinary mobile phone and connecting to the ship’s WIFI.

  Combining technical test with demonstration application, Zhongxing-16 carried out high-speed laser communication test on the geosynchronous orbit satellite for the first time, with the highest speed of 2.4 G.. Satellite laser communication has the advantages of large communication capacity, long transmission distance and good confidentiality. If the test is successful, it marks that China has reached the international advanced level in this field.

  On August 6th, 2016, China successfully launched Tiantong-1 satellite 01 in xichang satellite launch center, which is the first star of China satellite mobile communication system, also known as the "China version of maritime satellite", and its successful launch marks that China has entered the "mobile phone era" of satellite mobile communication.

  After the Wenchuan earthquake in 2008, the ground communication network in the earthquake zone was completely paralyzed. At that time, China did not have its own mobile communication satellite system, so it could only rent foreign satellite phones for earthquake relief. The international mobile satellite system has formed a number of global or regional mobile communication systems, which are not only widely used in personal communication, ocean transportation, offshore fishing, air passenger transport and other fields, but also can realize barrier-free communication and determine the location in the case of natural disasters such as earthquake, flood and frost. After the Wenchuan earthquake, Tiantong No.1 was established.

  The reporter learned that the technical indicators and capabilities of Tiantong-1 satellite have reached the level of international mainstream mobile communication satellites, and it has completely independent intellectual property rights. In particular, Tiantong-1 satellite has solved the technical problem of deploying an oversized antenna, making the satellite telephone terminal used on the ground more miniaturized and mobile.

  The selfless dedication of several generations of researchers has been passed down from generation to generation.

  Make China’s satellite industry from scratch. From lagging behind to leading

  In recent years, our communication satellites have been successfully launched and put into use, covering the cutting-edge technologies and applications in the development of communication satellites, such as broadcast and television live broadcast, Qualcomm broadband satellite, mobile communication satellite and data relay satellite. Looking back, when we started to develop satellites, we were not only poor. Moreover, the foundation is weak. Under such conditions, our researchers insisted on self-reliance and selfless dedication, and finally embarked on a road of research and development of China communication satellites. Although this road was not smooth, it also experienced setbacks and hardships.

  In the exhibition hall of the Fifth Academy of China Aerospace Science and Technology Group, real products from Dongfanghong-1 to Dongfanghong-4 satellites are displayed, which have witnessed the development of communication satellites in China.

  Dongfanghong-1 was China’s first artificial earth satellite developed by the older generation of space scientists and technicians through self-reliance under the conditions of poverty and weak economic and technological foundation at that time. Due to the limitation of technical level at that time, it did not have communication function.

  Zhang Wei, Senior Engineer of the Fifth Academy of Aerospace Science and Technology Group:After the success of this satellite, it actually created a precedent for our country’s artificial earth satellite, but its significance only reflects from scratch, so our satellite will be put into use after all.

  After the successful launch of Dongfanghong-1, in order to make the communication satellite truly practical, the older generation of space science and technology personnel, represented by Sun Jiadong and Qi Faren, established the belief of "developing China people’s own communication satellite on their own". After nine years of hard work, Dongfanghong-2 communication satellite was finally developed successfully. On April 8, 1984, Dongfanghong-2 experimental communication satellite was successfully launched, making China the fifth country in the world to independently develop and launch geostationary orbit satellites.

  Constrained by the technical level of electronic component development and material science research at that time, Dongfanghong-2 satellite had a small load and a short service life. The C-band transponder of the satellite had only two channels, while the C-slope transponder of the international advanced communication satellite had reached 24 channels at that time, and its service life was as long as ten years.

  Zhang Wei:At that time, the power it could provide was very small, because there were so many solar cells, so it could provide so much power. Therefore, at that time, the on-orbit life of our country’s communication satellites was relatively short, that is, five years, and the effective power it could provide was very low, so the so-called transponder number was just a few transponders.

  The main load of communication satellite is transponder, and one transponder can transmit more than ten sets of standard definition TV programs. The greater the load of communication satellite, the more transponders, which means that more radio and TV programs can be transmitted and more communication capacity can be provided. Zhang Wei told reporters that because Dongfanghong No.2 could not meet the needs of customers at that time, there was also a debate about "buying stars" or "making stars" in China. Under the circumstances at that time, astronauts had no choice but to develop Dongfanghong-3 satellite according to the international level at that time under the condition of weak technical foundation and poor facilities.

  Zhang Wei:Dongfanghong-2 is a spin-stabilized satellite. By Dongfanghong-3, we have a three-axis stabilized satellite. With the adoption of the solar wing, the technology has a great leap forward, and we can only inherit about 20% of the technical foundation of Dongfanghong-2, and the remaining 80% is based on the independent innovation of our astronauts in China.

  From the national project in 1986 to the successful launch of Dongfanghong-3 satellite in 1997, researchers have solved hundreds of technical difficulties in 11 years, gnawed down more than ten "hard bones" and experienced the pain of the first satellite launch failure. Dongfanghong-3 satellite not only achieved a leap in the development technology of communication satellites in China, but also provided a highly reliable communication satellite platform for China’s space industry.

  In 2000, Dongfanghong-4, aiming at the international first-class level, began to be developed. The design life of the satellite platform was increased to 15 years, and the number of transponders carried was increased to 52. At that time, the market goal of Dongfanghong-4 communication satellite was not only to occupy the domestic market, but also to go out and seize the international market.

  While researching and developing the communication satellite platform of Dongfanghong-4, they are also exploring the market of Dongfanghong-4. In May 2002, they signed a purchase order contract for Xinnuo-2 satellite with Xinnuo Satellite Communication Co., Ltd.; In May, 2004, he participated in the bidding for the whole satellite development and launch project of Nigeria Communication No.1 satellite, and stood out from 21 companies including the United States, France and Britain, and won the bid successfully.

  Zhang Wei:Dongfanghong-4 satellite, its weight reached 5 to 5.5 tons, and its load capacity reached about 600 kilograms. This level was actually at the same level as the international advanced level at that time, so through Dongfanghong-4, we actually realized a transformation process from following to running together.

  In 2010, focusing on the demand of high-power communication satellites in the next 20 years, a new generation of Dongfanghong-5 satellite with high load, high power, long life and expandability began to be developed. At the same time, the Fifth Academy of Aerospace Science and Technology Group is also tracking the most advanced technology in the world and expanding the technical level of the original satellite platform. In order to improve the payload of communication satellites, they have to make the electronic system smaller and smaller.

  Gong Jianglei, deputy director designer of the Fifth Academy of Aerospace Science and Technology Group: These products are actually a hardware product based on the integrated electronic system on our entire communication satellite.Now these four products have actually replaced more than 20 previous products. The previous products were relatively large in quantity and volume, and we have reduced them by about 50%, which is also a relatively leading level in the whole world.

  It is an inevitable choice for the Fifth Academy of Aerospace Science and Technology Group to follow the world’s leading technology and achieve technological transcendence in some technical fields. After graduating from Ph.D. in 2008, Chen Yue came to the Fifth Academy of Aerospace Science and Technology Group to be responsible for the control and promotion of communication satellites. Just after working for more than two years, he proposed to the institute the research on electromagnetic propulsion of communication satellites without working medium, which was still controversial at that time.

  Chen Yue, deputy director designer of the Fifth Academy of Aerospace Science and Technology Group:Everyone’s main doubt is that this technology may be scientifically researched and developed in engineering before it is fully explained. Is it risky or is there a principled error? This is the main controversy.

  Communication satellites in space need to adjust their attitude and maintain their orbits, so satellites will carry a lot of propellant. The traditional chemical propulsion method is to generate thrust by propellant oxidation. At present, the electric propulsion method used in satellites is to ionize the carried working medium gas, and then spray the plasma to generate thrust. Both of these propulsion methods need to carry working medium, that is, propellant and gas.

  Chen Yue:Figuratively speaking, these liquids or gases stored in the tank, once these working fluids are used up, the engine can no longer be used, and its life is up. And our current propulsion mode, this electromagnetic propulsion, is that as long as there is electricity, as long as the equipment can work normally, it can work and generate thrust.

  There is no technology and experience to learn from, and there is no reference to any foreign materials. This technology is in the initial stage of technical experiment at home and abroad, and Chen Yue and his team are facing great challenges.

  In order to encourage young people to innovate, the Fifth Academy of Aerospace Science and Technology Group set up a special fund for R&D and a special fund for doctoral growth to give financial support. Moreover, the core R&D personnel were not assessed for three years, and they were given strong support in personnel and experimental equipment to ensure that they concentrated on technical research.

  Chen Yue:Through the independent research and development fund of the Science and Technology Committee of our institute and the independent research and development fund in our institute, we can support us, so that we can focus on this matter without worrying about the guarantee of conditions. It can be said that this is like an incubation. If there were no such incubation conditions at the beginning, we would not have this progress.

  The reporter learned that at present, many key technologies of Dongfanghong-5 satellite platform, which represents that China’s communication satellites have reached the international leading level, have made major breakthroughs and need to be verified in orbit. Dongfanghong-5 platform has a total satellite power of 30,000 watts, a payload of more than 2,000 kilograms, and 120 transponder circuits, and some technical indicators exceed the level of developed countries. Most of the products on Dongfanghong-5 platform can be truly localized, independently controllable and no longer dependent on imports.

  Half-hour observation: Aerospace, China’s brightest "business card"

  From the first Dongfanghong-1 satellite to the world-leading Dongfanghong-5 satellite, the development of China’s communication satellites has gone from scratch, from following to running in parallel.

  The development level of communication satellites represents a country’s scientific and technological level in the field of space science and technology, and it is also an important embodiment of a country’s comprehensive strength. Although we have experienced failures and setbacks in the development of communication satellites, we have finally been at the forefront of international communication satellites in just a few decades.

  This is the result of the silent and selfless dedication of the vast number of aerospace science and technology workers, and it is also a continuation of the spirit of the older generation of astronauts.

"Star" fruit cherries witness the world opportunities brought by the opening of China.

Original title: "Star" fruit cherries, witnessing the world opportunities brought by opening China.
During the Spring Festival holiday this year, entries such as "Top-flow of adult cherries" and "Freedom of cherries" rushed to Weibo for hot search.
"The children at home like to eat cherries, which are red in color, sweet and delicious, and just listed during the Spring Festival, which means that they are red and hot, and now the price is not expensive, so I will buy more food." Ms. Chen, a resident of Chengjiaqiao Street in Changning District, Shanghai, expressed the feelings of many consumers.
As a "star" in imported fruits, cherries have become one of the popular consumer fruits in the Spring Festival this year. From Chile across the ocean to China, the trip to the cherry market proves that opening China is always an important opportunity for world development.
Open the map of the world, China and Chile are separated by oceans, with a linear distance of nearly 20,000 kilometers. Delicate and beautiful fruits come from mountains and rivers, with delicious flavor and good quality and low price. What’s the story behind this?
Imported goods flew into the homes of ordinary people, which witnessed the breadth of China’s high-level opening up. In recent years, from new varieties of apples and bananas to new faces such as durian and avocado, more and more special fruits from all over the world have been brought to the table of China people. From promoting the negotiation of FTA to hosting China International Import Expo(CIIE), to continuously optimizing the convenience of customs clearance, open China and welcome the good things from all over the world with open arms. In 2023, the Customs granted 146 kinds of sub-high quality agricultural and food products from 51 countries and regions to be exported to China, constantly meeting the diversified needs of domestic consumption and people’s yearning for a better life.
Taking cherries as an example, in 2008, China and Chile signed the Protocol on Quarantine of Chilean cherries and plums exported to China, and Chilean cherries were officially allowed to enter the China market; Since 2015, 97% of goods in China and Chile have achieved zero tariffs, and cherries are one of them. At present, China has signed 22 free trade agreements with 29 countries and regions.
Opening up market access is the first step, and the continuous domestic circulation has set up a high-speed passage to the people’s table for imported cherries. Although cherries are delicious, they are perishable and have a short shelf life, which requires high transportation and storage conditions. E-commerce channels continue to sink, logistics timeliness continues to improve, and refrigeration technology continues to improve. A more sound and efficient circulation system allows cherries to get off the branches and serve on the table, reaching consumers in the north and south of the country in a short time, detonating market demand and becoming the "new favorite" of national consumption.
On the eve of the Spring Festival this year, the "Chile-Tianjin Cherry Express Line" opened for the first time in Beijing-Tianjin-Hebei region, with the fastest loading and unloading efficiency, the best customs clearance process and the shortest delivery time, achieved the coverage of Beijing-Tianjin-Hebei fruit wholesale market in about 5 hours, showing the efficient coordination effect of China’s unified big market.
The constantly optimized business environment proves the depth of China’s opening up. The milk produced in foreign pastures on Monday can get on the plane on Tuesday and go straight to the dining table of consumers in China on Wednesday … This shows China’s attitude of constantly optimizing the business environment through system innovation and process improvement.
Not only is it bought in, but under the mutual promotion of domestic and international double circulation, China’s super-large-scale market is playing a huge advantage of "demand traction supply". Today, more than 92% of Chilean cherries are exported to China. The vitality of China market has created new opportunities for the development of Chilean cherry agriculture. In recent years, many Chilean fruit farmers have introduced new planting techniques to improve the precision of industrial management, the industrial assembly line has become more mature, and the industrial scale has been rising, which has driven the cost and price of cherries down.
A small cherry, riding the warm current of promoting high-level opening to the outside world, and riding the domestic and international double-cycle express train, not only sweetened the tip of China people’s tongue, but also beautified the life of the residents in the country of origin. In the new journey towards Chinese modernization, more than 1.4 billion China people’s yearning for a better life will release more surging market momentum, drive more imported goods to fly from the other side of the ocean to the homes of ordinary people, and the price will gradually change from expensive to "close to the people", and more "cherries" stories will be staged.
If the world is good, China will be good; If China is good, the world will be better. China has been the second largest importer in the world for many years in a row. Super-large-scale import has strongly supported domestic production and supply, improved people’s livelihood, and promoted the economic development of various exporting countries.

"I got 66 in the English exam, and it was really terrible when I reviewed it!" Remember Wang Ping, a middle-aged candidate interviewed by Yangzi Evening News/Zi Niu News reporter on the first day of the 2024 postgraduate entrance examination? On the 26th, Wang Ping found his test scores. He was indignant, but he didn’t regret his efforts. "It is still a little short of the retest line of Nantah last year, but it has also worked hard." Wang Ping also had an opportunity to take a postgraduate study. "But at that time, I received an OFFER from my unit at the same time, and the salary offered made me very satisfied, so I gave up my postgraduate study and chose a direct job."
As an old man, he walked into the examination room again and took the exam with the students after 00. Wang Ping obviously had some difficulty in the review stage. "Struggle repeatedly in forgetting and reciting. Work, family and review cannot be ignored, and it is really difficult to take care of all three. " Will you take the exam next year? Wang Ping didn’t think it over, but there are more and more highly educated young people around him. It is not impossible for Wang Ping to "last stand" again.
Is it possible to adjust and reduce points?
"I heard that the score line will drop this year. I don’t know if it is true." Suqian candidate Xiao Jia’s scoring process is even more thrilling. Xiao Jia applied for the college of literature of a popular 985 university. "I got 366. According to the national line of previous years, I crossed the line!" I turned around and inquired about everyone’s situation in the "comrades-in-arms group" of the postgraduate entrance examination. Suddenly, I found that there were many partners with higher scores than myself. "This major has a total of 20 candidates, and some of them are exempted from students. There are really not many plans left for our postgraduate students." Xiao Jia began to give himself two hands. "This score is not low. Maybe there is hope for a change. It is not easy to review the postgraduate entrance examination once. If you can be admitted, try to give yourself an explanation. "

Postgraduate entrance examination is not the only thing in life.
Spring tricks are in place, and preparing for job hunting is also an option.
Li Muyuan, deputy director of the Student Affairs Office of Nanjing University of Finance and Economics and director of the Student Employment and Entrepreneurship Guidance Center, said in an interview that after the graduate examination scores are announced, students can make comprehensive analysis of their scores and rankings and actively prepare for the second interview. If there is a gap between the expected score and the online score, you can actively pay attention to the postgraduate adjustment information and face the reality and immediately start preparing for job hunting.
At present, the spring recruitment has been started, and many units have issued spring recruitment announcements. Li Muyuan suggested that students should make good use of the "Golden Three Silver Four" period, pay more attention to the employment information released by national and provincial education departments, local human resources departments and universities, and actively break the information gap. At the same time, the resume is modified according to the job requirements. At present, many enterprise job fairs adopt the mode of machine reading and screening resumes, which requires students to find the right keywords in their resumes to match. If a resume contains keywords that match the requirements, then the resume has a higher chance of passing the screening. "Opportunities are always reserved for those who are prepared", and I wish the students all the best!
