　　Xinhua News Agency, Beijing, May 5 (Reporter Meng Hanqi, Jia Yuankun and Xie Jiao) On May 5, China’s first large jet C919 with completely independent intellectual property rights rushed into the sky at Shanghai Pudong Airport, successfully completing its first flight mission, fulfilling the "airplane dream" that Chinese people had been waiting for for for half a century. The successful first flight of a large plane not only inspired the aviation industry, but also closely related to the lives of ordinary people.

　　The upgrading of aviation industry sounded the "first shot"

　　C919 large passenger plane is a large jet civil aircraft developed by China in accordance with international civil aviation regulations, with completely independent intellectual property rights. According to the advanced aerodynamic layout, structural materials and airborne system, the developers have planned 102 key technical problems, including the integrated design of aircraft engine, the control law design of fly-by-wire flight control system and active control technology.

　　Don’t think that C919 is just a cold code name, but this name has great expectations. The full name of C919 is COMAC919, in which "C" is the initials of China and the abbreviation of the English name of COMAC, the main manufacturer of China. The first "9" means everlasting, while "19" means that the first medium-sized passenger plane in China has a maximum capacity of 190 seats.

　　The reporter learned from China Commercial Aircraft Co., Ltd. that the first flight of the C919 lasted for more than one hour, the cruising altitude of the aircraft was about 3,000 meters, and the cruising speed was about 300 kilometers per hour.

　　It is generally believed in the industry that the successful maiden flight of C919 has sounded the first shot for the upgrading of China’s aviation industry, which will have a far-reaching impact on large aircraft manufacturing and even high-end manufacturing. With the introduction of relevant industrial policies, it will not only help to accelerate the formation of domestic large aircraft industrial clusters, but also expect long-term overall returns on related stocks. For example, machine integrators, system-level integrated suppliers and raw materials fields will usher in a broad market space.

　　Upstream and downstream industries "take off"

　　The big plane was successfully launched and cheers came from all over the country.

　　The production, matching and assembly of C919 large passenger aircraft involved more than 200 enterprises and 22 provinces and cities, involving nearly 200,000 people, and promoted the establishment of 16 joint ventures in airborne systems such as avionics, flight control, power supply, fuel and landing gear. Chen Shangyong, an external flight consultant of Yihang Aviation Group, said that the mass production of C919 will drive the development of upstream and downstream industries such as metal materials, metallurgical processing, CNC machine tools and power control, and its pull on related markets will exceed one trillion.

　　According to the forecast, China’s air transport market alone will need nearly 6,000 trunk passenger planes in the next 20 years, with a value of nearly 900 billion yuan.

　　The vigorous development of industry and increasing demand will directly affect employment. According to statistics, if the civil aviation large aircraft project forms an industry, there is a demand for 80 workers in the downstream parts field behind an aircraft factory worker; The civil aircraft project will provide 12 times the employment opportunities for related industries. For every $100 million invested in the aviation industry, aviation and related industries will produce $8 billion in 10 years.

　　As a "professional nose user", AVIC Chengfei Civil Aircraft Company has driven the development of more than 20 upstream enterprises around, some of which are providing accessories for star models such as Boeing and Airbus. Tang Jianzhong, deputy chief engineer of AVIC Chengfei Civil Aircraft Company, said that with the commercialization of domestic aircraft, more jobs will be created and the employment of a large number of high-tech talents will be solved.

　　It is matched with the improvement of the training mechanism of aviation high-skilled talents. It is understood that with the launch of the C919 project, the School of Aeronautics and Astronautics of Shanghai Jiaotong University set up a special class for civil aircraft design to train professionals. With the development of C919 project, GCAT, jointly organized by Comac of China, General Electric Company and Avionics International, has also been promoted.

　　When can the people "fly first"?

　　"C919 integrates the highest scientific and technological applications in the field of civil aviation manufacturing at home and abroad, with a high design starting point. I believe it will definitely become a star model. " Liu Shaoyong, chairman of China Eastern Airlines Group and a national super pilot, said.

　　"For the people, the success of the flight test of the C919 means that there will be new options in addition to Airbus and Boeing in the future, and it is a domestic model option." Chen Shangyong said. Netizens also praised it, saying that "the big plane has fulfilled the China aviation dream of ordinary people" and "domestic aircraft will be supported after commercial operation in the future".

　　When we are happy, many people secretly expect: When can we get on the C919 passenger plane?

　　At present, the market order for C919 large passenger aircraft has reached 570. In 2016, China Eastern Airlines became the first user of C919 large passenger aircraft in the world. Within one year after the first flight of C919 passenger plane, Comac China and China Eastern Airlines will start negotiations on the supply and demand of five aircraft.

　　Although the first flight was successful, it is still a long way from commercial operation. It is understood that the first flight is not a commercial operation of carrying passengers, but a step required to obtain various qualifications. After the first flight of C919 is successful, it needs to complete all kinds of forensic tasks before mass production. According to industry insiders, it takes about 3 or 4 years for civil aircraft to obtain evidence for flight test, and it will not enter the commercialization stage until the evidence is obtained.

　　"The agreement between China and Europe and the United States on airworthiness forensics has opened up a situation for the smooth forensics of C919 aircraft in the United States and the European Aviation Administration. We look forward to the early success of obtaining evidence for C919, and look forward to delivering it to us for commercial operation as soon as possible after completing various forensics." Liu Shaoyong said.

"In the past, participation in outdoor activities was led by the team leader. Now I hear a new name’ outdoor manager’. What is the difference between this and the team leader?" Recently, the reporter interviewed several senior managers in the circle with this question.

An Chenran, the manager of Wingray Frisbee, told the reporter: "The team leader and the outdoor manager are different in identity and work content. The work of the tour leader is to ensure the smooth progress of the activity and take care of the safety of each participant, including the prior route arrangement, departure time and itinerary. The outdoor manager has a wider scope of work, not only planning and executing activities, preparing sports equipment, setting up scenes, serving customers, making meals, etc., but more importantly, operating communities, managing daily affairs, customizing business customer activities, expanding the influence of brand activities and planning the future development of brand activities. "

With the rapid development of outdoor sports in China, outdoor managers came into being with the needs of the market. "After 2021, more and more people want to go out to exercise, but they don’t want to go far away. They hope to find a group of like-minded people and enjoy their leisure time together, and the outdoor manager becomes the person in charge of organizing this activity. " Lin Zhao, product manager of an outdoor travel platform, said, "The outdoor camp manager and outdoor mountaineering manager in the activity now … they undertake different projects but have the same job responsibilities. They generally have a stable job with good income, and the outdoor manager is only their part-time job. Doing this job requires strong activity planning skills and social communication skills. After a good plan is positively responded by everyone, it can quickly organize an event and competition. "

Recently, Liu Wei, the manager of Hangzhou Badong Women’s Frisbee Community, organized a special invitational tournament for women’s frisbee. In the early stage of the event, Liu Weixian posted relevant event information in the group and social media, and made an activity plan. On the opening day, she came to the stadium in advance to set up the corner of the Frisbee. "This competition has the first women’s frisbee team in China, the champion team of China Women’s Frisbee Open in 2023 and the third runner-up of China Women’s Frisbee Open in 2023. The competition is both intense and interesting. The fee for this competition is 80 yuan per person, with half price for students. Our team consists of team committees, accountants, designers, disciplinary committee members, etc. If we count the venue rental fee every time, sometimes it is a loss to hold a game. The income of the manager is mainly the total income of an activity MINUS the coach fee and venue fee. Although there is not much left in the end, I will always stick to it because I am willing to play, run and compete with you. " Liu Wei said.

In addition to organizing Frisbee competitions, Liu Wei’s outdoor manager work is also responsible for daily professional training of Frisbee. With 17 years’ experience in frisbee, she has participated in hundreds of domestic competitions and won more than 30 championships. As a coach of the China women’s team in the 2023 Asian Oceania Frisbee Championships (Philippine Station), she has carved her love for frisbee into her bones. "We organize training every Thursday, and the training content in the last two weeks is the practice of passing and receiving. To tell the truth, as an outdoor manager, the biggest feeling is fatigue after a day’s work, but I want more women to experience the happiness of Frisbee and let every participant become the leader of the competition. I hope the charm of women’s Frisbee events can attract more people to participate. " Liu Wei said this. (From March 21st, China Sports Daily, 07 edition)

The new rise of science and technology has also created the heyday of an era. With the growth of the global population, it has promoted the progress and development of industry invisibly based on the need for convenience. The problem of food and clothing for modern people has been basically solved, and the experience brought by science and technology has become people’s spiritual food, bringing more fun and convenience to life.

Looking at the past, no matter from the industrial field or the consumer electronics field, the thinking and manufacturing power of the Internet is relatively backward, and the consumption power is weak, so the application scale of electronic connectors is very different from the present situation. With the opening of the Internet, the new promotion of artificial intelligence and the Internet of Things has greatly changed the life around us.

Intuitive changes that can reflect the development of science and technology are constantly being popularized in life, and the application of smart home makes people sigh! Smart refrigerators, smart TVs, smart washing machines, smart speakers, smart lighting, smart air conditioners, smart door locks, intelligent curtain, etc., with the empowerment of the Internet of Things, have the ability to connect to the network, and have gradually become the new focus of the development of the Internet of Things in 2019.

The application of electronic connectors wins in the Internet of Things and artificial intelligence.

In the field of consumer electronics, whether it is smart home, service robot or smart wear, with the development trend of intelligence, the application of electronic connectors has increased dramatically, showing an unprecedented good trend, which is a new height for the past.

The application of electronic connectors wins in the Internet of Things and artificial intelligence.

According to authoritative statistics, the development of the Internet of Things is growing at an annual rate of 25%. It is estimated that by 2024, the market scale of the Internet of Things is expected to exceed 2.2 trillion yuan. Secondly, the application of the Internet of Things is more extensive, and it penetrates deeply in many industries such as electric power, transportation, industry, medical care, security and so on. In this new field, it will be a new blue ocean for the electronic connector market!

These are some of Xiaobian’s opinions. Readers can also discuss with Xiaobian what they think later.

Chelsea have been paying attention to Nkunku for a long time. As many teams are eyeing this Leipzig Red Bull general, the Blues hope to win him first in the winter window. In this way, you can avoid joining the fierce battle for Ming Xia. The Blues know that it is not easy to take such an important player from Leipzig Red Bull in the middle of the season, and I’m afraid it will cost more money than Ming Xia. However, Chelsea is willing to do so, rather than wait until next summer to fight with other teams.

Nkunku has started 14 games in 15 games so far in the new season, and is the regular main force of the team. The data performance of scoring 10 goals and assisting once and participating in the team’s 16 goals is enough to show that this general is still in an excellent state in the new season, which is not much different from last season. As far as Leipzig Red Bull’s player operation strategy is concerned, the price-in-place area is, uh, no sale, but the club prefers to let Nkunku go at the end of the season, not in the middle. There was a player trade between Chelsea and Leipzig Red Bull. Werner is an example. At the beginning, the Blues met the buyout request of Leipzig Red Bull, and directly won Werner in full. This season, Leipzig Red Bull bought back, and Chelsea didn’t do much to block the price.

It can be seen that the two clubs still maintain a good relationship. Chelsea hope to use this relationship to persuade Leipzig Red Bull to let Nkunku go in the winter window, and the Blues will try their best to meet the requirements in terms of price. It is reported that Nkunku’s current transfer fee will reach 52 million pounds. It is reported that Chelsea has reached an agreement with the player on a five-year contract, but it has not yet been formally signed. Chelsea hope to finalize Nkunku’s joining as soon as possible to avoid big sleep. After all, there are many teams interested in Nkunku. Although an agreement has been reached with the players, after all, the contract has not been signed, and there will still be variables.

If the negotiations go well, the Blues even hope to reach an agreement with Leipzig Red Bull on the Nkunku deal before the World Cup starts. The current position of the Blues is to win Nkunku as soon as possible, while the Red Bull of Leipzig still insists on Ming Xia’s position of re-selling Nkunku. In addition to Nkunku, Chelsea also want to introduce another middle-front-back player, who is currently playing for Trossat in Brighton. When negotiating with Brighton about its coach Potter, the Blues noticed Trossat. This frontcourt player’s contract with Ming Xia will expire. If a team outside the Premier League persuades players to vote in January, then they can win it without a visa.

Now Atletico Madrid is very interested in Trossat, hoping to win the 27-year-old Argentine frontcourt attacker in the winter window. Chelsea will have to compete with Atletico Madrid, and the Blues have an advantage in the competition for Trossat. Porter had previously coached in Brighton and had a cooperative relationship with Trossat. If Porter contacts Trossat personally, the players will be more willing to vote. If he joins the Blues, Trossat doesn’t have to go to other leagues to get used to playing again. These are the advantages of Chelsea. However, Atletico won’t give up Trossat easily, and will make every effort to pursue it. The primary goal of Chelsea’s winter window is Nkunku, and Trossat is not the primary goal.

Ever since humans realized the importance of robots to human life, they have been focusing on the development of artificial intelligence technology. In these years, the development speed of artificial intelligence technology has been faster and faster, and now there are not only sweeping robots, but even robot attendants.

According to foreign media reports, the humanoid robot developed by a laboratory in the UK appeared in everyone’s sight again. The humanoid robot made a series of human body movements and even smiled in front of the mirror. As soon as the humanoid robot appeared, it was watched by a large number of friends, and its lifelike expressions and actions were once surprising. It can be called the most advanced humanoid robot in the world, and its every move and smile are strikingly similar to others. Once the news spread, it quickly caused a heated discussion among netizens in Guangfa.

After seeing the photos, many netizens will say that if the robot is dressed and put on a hat, it may really think that it is a human being. More people will say that this robot will produce wisdom, and if he has his own wisdom, it will pose a threat to human society. This is not what we are worried about, but what Hawking, a great scientist, once worried about.

Then the question is, if robots are conscious, will they one day replace humans? Will Zeng Lao’s prophecy come true?

Hawking once said when he was alive that he suggested that human beings should not develop robots too vigorously, or they might eventually be destroyed in the hands of robots.

People are conscious, ecstatic, depressed, grateful to those who have helped them, and reflect on their mistakes. People are thinking all the time, producing emotions and thinking all the time. But the robot is not necessarily. After all, it is only controlled by chip technology, and it still depends on people to research and develop it. Humans have the ability to reproduce, but robots haven’t been able to achieve this function yet. There was a famous professor Zeng Lao who boldly predicted that mankind would be destroyed by science and technology. So is the truth really what he said? It is said that science and technology change our lives. How can human beings be destroyed because of science and technology?

It is understood that this humanoid robot developed in the UK can wiggle its shoulders, blink its eyes, even touch its face in front of the mirror, frown and smile. This is not a human being, and the actions it does are what we often do. In addition, we unexpectedly found that the arm joints of humanoid robots are as flexible as those of human beings. If I hadn’t seen its mechanical arm, I would have thought it was a man waving his arm if I had dressed it! However, the walking and moving function of this humanoid robot has yet to be developed. The reason why its facial expression is so realistic is that it is implanted into the human face.

Now, the latest robot developed in the UK is actually regarded as the top robot level. It is the top robot in the world in terms of materials and mechanical technology. Similarly, Japan is also leading in the development of artificial intelligence. Maybe many people know that Japan introduced a beauty robot some time ago, and it can even help Japanese otaku solve their physiological needs. At that time, what they made was very perfect, but they couldn’t make very delicate movements and expressions.

Although technological innovation will bring us infinite convenience, if we rely too much on robots, we will eventually lose our hands-on ability. Robots are artificially developed, developed to serve people and obey human commands. While vigorously developing artificial intelligence, it must be legal and compliant, and robots should be constrained by systems.

According to the current science and technology, it is completely impossible to create robots that are exactly the same as human beings. Robots of this grade can be destroyed instantly even if they have spirituality. What’s more, they themselves are just not too complicated mechanical structures, and they are unlikely to produce spirituality.
