　　Sohu Sports News On November 28th, Beijing time, Group F of the Champions League ended the fifth round of competition. Manchester United beat Sporting Lisbon 2-1 in stoppage time at home at Old Trafford, while Rome beat Dynamo Kiev 4-1 away to secure promotion to the top 16 in advance. Sporting Lisbon won the third place in the group and can continue to participate in the UEFA Cup. ——

　　Manchester United 2-1 Sporting Lisbon

　　As the only team in the top 32 that scored 12 points in the first four rounds, Manchester United can ensure the first place in the group as long as it wins, and Sporting Lisbon can’t afford to lose this game if it wants to retain its promotion hope.

　　However, judging from the past records, Sporting Lisbon’s trip to England was run out of luck. Manchester United’s previous 8 home games against Portugal were unbeaten with 7 wins and 1 draw, and nearly 32 home games in the Champions League were only lost to AC Milan. On the other hand, Sporting Lisbon, nearly 11 Champions League away games have only a poor record of winning.

　　In this game, Ferguson was not affected by the unexpected loss to Bolton last weekend, and continued to rotate the starting lineup. O ‘Shea, Fletcher and Kuszczak were all allowed to start, Vidic recovered from his back injury and returned to the starting line instead of Pique, while C- Ronaldo and Nani played against their old club in the frontcourt respectively. Sporting Lisbon, Ledesson injured his right thigh at the weekend, but the injury was not serious. Patricio, 19, still started in the Champions League for the first time instead of stojkovic, who suffered a hip injury.

　　At the beginning of the first half, although Sporting Lisbon had a slight advantage in controlling the ball, it was slightly stronger than Manchester United in terms of offensive sharpness. In the second minute, Anderson obliquely passed C- Ronaldo, and the Portuguese international scored after running 50 meters with the ball. Unfortunately, Saha was a little slow. Subsequently, Nani got two chances in the left rib, but they failed to form a real threat. In the 12th minute, Motinho turned to his right rib 24 meters away, and his right foot slanted the low ball and it would miss. Two minutes later, C- Ronaldo received Carrick’s oblique cross from the right side of the frontcourt and then shot low, which also missed the long post.

　　In the 19th minute, O ‘Shea made a cross on the right, C- Ronaldo made a heel pass, and Saha inserted an oblique shot and still missed the target.In the 21st minute, Veloso distributed the ball to the right. Abel caught the ball and suddenly volleyed his right foot near the sideline. Kuszchak, who was unresponsive, made a save, but the ball flew into the net.In the 26th minute, Ledesson once again sent the ball to Manchester United’s net, but the Brazilian striker’s offside goal was invalidated. Three minutes later, Bohr increased the front of the restricted area and turned around to shoot, and the angle was slightly confiscated by Kuszchak. Since then, although the scene is lively, neither side has created a really threatening shooting opportunity. In the first half of the game, Manchester United fell 0-1 behind Sporting Lisbon and entered the halftime break.

　　At the beginning of the second half, Ferguson sent Ryan Giggs and Carlos Tevez out. Only 25 seconds after the opening, Tevez successfully broke the ball on the right side of the frontcourt, and Hade had no choice but to put down the shovel and sweep down the Argentine beast and was given a yellow card warning. In the 50th minute, C- Ronaldo took a free kick from Giggs, grabbed a header, and was deflected. Seven minutes later, C- Ronaldo pushed horizontally, and Saha adjusted when he could kick. As a result, the ball was destroyed before kicking.

　　In the 59th minute, Ryan Giggs kicked off the right corner, and Nemanja Vidic jumped high and tossed his head to attack the top of the goal.In the 61st minute, O ‘Shea’s cross on the right side was slightly stronger, but Evras quickly inserted the ball and successfully intercepted it. After the cross ball was blocked, it bounced in front of C- Ronaldo, and the Portuguese international hit the door with his right foot. After the ball hit Harder, it touched Tevez’s foot 6 meters in front of the door and changed lines to enter the goal.In the 64th minute, Veloso’s shot on the edge of the restricted area was slightly higher than the lintel. Four minutes later, after receiving Tevez’s cross, C- Ronaldo’s low shot was blocked by Patricio with his foot, and Anderson shot wide 35 meters away. In the 74th minute, Tevez made a long pass from the right, and C- Ronaldo leaned forward and headed the ball from a small angle.

　　In the 76th minute, C- Ronaldo hit the door with his left foot and slid from the front door to the bottom line. Three minutes later, Anderson picked the ball, and Hargreaves, who had just come off the bench for less than one minute, plugged in and shot it and was blocked by Patricio with his foot. In the 80th minute, C- Ronaldo failed to get a yellow card because he was fouled. Two minutes later, Evras was also given a yellow card warning for diving in the restricted area.In the 92nd minute, Anderson was violated by Ledesson to create a free kick. C- Ronaldo took a free kick 26 meters away from the left rib and shot his right foot directly to the right side of the goal to complete the reversal, which made C- Ronaldo score 11 goals in his personal season and continue to sit side by side with Ibrahimovic at the top of the Champions League scorer list with 5 goals.In the end, Manchester United defeated Sporting Lisbon 2-1 at home, continued to maintain the record of winning the Champions League this season, and expanded the winning streak at home to 9 games, thus locking the top spot in the group one round ahead of schedule. -This year’s Golden Globe Award will be announced on December 2nd. Do you think C- Ronaldo is a suitable candidate for the Golden Globe Award?

　　CCTV News:There are representative major projects and major projects in each era, and those super projects have become the symbolic symbols of the times, which embodies the hard work and creativity of the people of China and also witness the road of China’s revival and rise.

　　Shield machine is a necessary equipment for tunneling, and it is also a high-end equipment focused on "Made in China 2025". At one time, the technology and overseas market of super-large diameter shield machine have been monopolized by western countries for more than a century. In May this year, the super-large diameter shield machine independently developed by China will go abroad for the first time and become a new "national business card" for China.

　　In May, this super-large diameter shield machine with a diameter of 12.12 meters and a weight of 2,200 tons is about to leave for Bangladesh. Although it is the weekend, the manufacturing team is still making the final confirmation of the export shipment plan.

　　For Zhang Boyang, the person in charge of this shield machine, it is not the first time that there is no weekend. The shield machine exported this time is not the most difficult project he took over. At the same location, they once manufactured the first super-large diameter shield machine with independent intellectual property rights in China — — "Tianhe", with a diameter of 15.03 meters and a weight of 6,500 tons, was used to excavate the Yangtze River tunnel in Nanjing at that time.

　　Zhang Boyang, head of CCCC shield machine project: "This was the most difficult geology in the world at that time. It was soft on the top and hard on the bottom. If it was all hard, it would be easy and even."

　　Zhang Boyang is the commander of Nanjing Yangtze River Tunnel Project. At that time, only one foreign company in the world had experience in manufacturing shield machines with similar conditions, and the construction party planned to order two shield machines from this company.

　　Zhang Boyang, head of CCCC shield machine project: "700 million one, two 1.4 billion, no price reduction. You can’t rely on others to import all the time. Once they wean you from food, you will die, so we are determined to make it ourselves. "

　　It’s better to throw off your arms and do it yourself than to cry your head off and beg for help. A big country’s heavy weapon must be in its own hands. As an engineer of this project, Zhou Jun was mainly responsible for research and development.

　　Zhou Jun, Chief Engineer of CCCC Shield Machine Project: "The pressure is enormous. Everyone thinks it is incredible, and there are doubts outside."

　　In the process of research and development, many technical problems appear for the first time, so we can only cross the river by feeling the stones. The research and development of core components has made everyone think hard.

　　Zhou Jun, Chief Engineer of CCCC Shield Machine ProjectThe cylinder is the core component of the shield machine, and the shield machine moves forward by the thrust generated by the cylinder. Before that, they were all imported from abroad. Our super-large diameter shield cylinder is a luxury car, 500,000 yuan each. "

　　Tianhe needs about 50 such cylinders. In order to realize the localization of core components, the R&D team made great efforts and made up their minds to gnaw this hard bone.

　　Zhou Jun, Chief Engineer of CCCC Shield Machine ProjectWe employees are the earliest to get off work at 11 pm. I basically go to work after 7 o’clock in the morning and get off work around 1 o’clock, every day. Through four to five months of experiments, we have come up with a set of manufacturing inspection standards for large-diameter shield cylinders. "

　　After nearly half a year of technical research, the domestic shield cylinder finally came out, and the cost of one cylinder was 300 thousand yuan cheaper than that of imported cylinders. A super-large diameter shield machine consists of tens of thousands of parts of different sizes. Behind every domestic part is hard work. The research and development of Tianhe has been designed, modified, tested and revised thousands of times. There are more than 7,000 drawings confirmed in the final design of the whole equipment, which are more than one person high when stacked together.

　　Zhou Jun, Chief Engineer of CCCC Shield Machine Project: "Everyone thought the same thing as me at that time, that is, we built these two machines. At that time, China should be said to be the shield machine with the most advanced technology, the largest diameter and the highest difficulty. Everyone had this sense of accomplishment at that time, that is, this kind of glory for the country, this kind of courage, including this spirit, that is to say, since I have done this, I must do it well. "

　　After 14 months of hard work, in July 2012, China’s first super-large diameter shield machine "Tianhe" was officially put into use, and the two shield machines saved nearly 800 million yuan for the country. However, can this shield stand the test of super engineering?

　　Zhang Boyang, head of CCCC shield machine project: "The most painful thing was in 2013, when the cutter head got stuck. Just a few days before the Spring Festival, I didn’t leave the construction site for half a step, and I stayed in the shield machine for observation and analysis every day. "

　　The cutter head suddenly stopped turning during the excavation of the Yangtze River tunnel, and these 59 days were the most difficult days for everyone.

　　Zhang Boyang, head of CCCC shield machine project"This is not only an enterprise, but also the pressure from China people. You let foreigners see Chinese jokes. This pressure is really huge, even if you cut my meat. "

　　After a long period of hard thinking, Zhang Boyang made a bold suggestion.

　　Zhang Boyang, head of CCCC shield machine project: "I retreated the cutter head and shield body of this integral shield machine, which is technical and has never been seen before. But I also evaluate and analyze what risks it has, how to retreat, and how much strength it needs. I use the telescopic mechanism and oil cylinder of the cutter head, and every time I retreat 10 mm, 10 mm, that’s all. "

　　After two months of persistence, the cutter head finally turned again. In July, 2015, after three years, Tianhe came out of the hole at the bottom of the river and saw the light again. Many people present cried with joy.

　　Zhang Boyang, head of CCCC shield machine project: "Without responsibility, there is no innovative spirit. You dare not take responsibility, do you dare to innovate? We are not willing to do this. How can China’s manufacturing industry develop? "

　　Tianhe has achieved 50% localization rate, and the localization rate of shield machines to be exported to Bangladesh has increased to 95%. It will be used in China’s largest overseas shield road tunnel project, and help the country’s "Belt and Road Initiative".

　　Xinhua News Agency, Shenzhen, January 22nd Title: Stick to it for a better reunion — — Shenzhen Express Takeaway Brother’s New Year’s Eve Running List

　　Xinhua News Agency reporter Zhao Ruixi

　　In the early morning of New Year’s Eve, Yang Lei went out on his electric car and was busy collecting and dispatching parts in several communities in Shenzhen Nanshan Science and Technology Park. This is his 17th year as a courier. He can’t remember how many times he received the delivery on New Year’s Eve. "After working as a courier, he didn’t go back to his hometown for the New Year."

　　On the morning of January 21st, at the gate of the residential area to be delivered, Yang Lei moved the boxes of express delivery out of the car. (Photo by Xinhua News Agency reporter Liang Xushe)

　　"My wife and two children are in Shenzhen. Many younger brothers’ families are not around, giving them the opportunity to go home. " Yang Lei said, "The company will also give rewards for going to work during the Spring Festival, and give compensatory time off after the holiday. My wife works in a supermarket and also works during the Spring Festival. Both children are in junior high school, they can understand us, and they can also heat their own meals and take care of themselves. "

　　This year, SF Express, where Yang Lei is located, set up a special incentive package and warm-hearted care activities for the Spring Festival totaling more than 400 million yuan to encourage employees to stick to their posts.

　　Yang Lei told reporters that the peak of receiving and dispatching parts is before the Spring Festival, and the workload during the Spring Festival is not too heavy. He, who is usually responsible for receiving and dispatching office buildings, went to support the receiving and dispatching work of residential quarters during the Spring Festival. In the four hours in the morning of New Year’s Eve, he received more than 80 tickets. "Under the superposition of various incentives, the Spring Festival can earn more than 10,000 yuan this month."

　　On the morning of January 21st, Yang Lei (former) was busy sorting express delivery. (Photo by Xinhua News Agency reporter Liang Xushe)

　　Near noon, Yang Lei was almost busy with the delivery task in the morning. At this time, Shen Jinfeng, a takeaway rider in Longhua District, got busy and rode his electric car between the restaurant and the community.

　　In 2021, Shen Jinfeng joined the US Mission and became a full-time takeaway in Longhua Minzhi District. He said: "Takeaway is an industry with more work and more rewards. As long as you are willing to pay, you will get a reward." In order to earn more money, he has chosen to stay alone in Shenzhen to deliver meals during the Spring Festival for two consecutive years.

　　Meituan has invested more than 500 million yuan this year as a subsidy for riders to stabilize their posts during the Spring Festival, including the subsidy for staying in the post, the red envelope for starting the Spring Festival, the red envelope for duty, and the subsidy for stepping back to work.

　　On New Year’s Eve, there were not many take-away orders. Until 1 pm, Shen Jinfeng sent out a total of 10 takeaways. "Although there are not many orders, the delivery fee per order is much higher than usual. I earned more than 9000 yuan in the Spring Festival last year. This year’s Spring Festival will get all kinds of rushing rewards, and you can earn more than 10,000 yuan. " Shen Jinfeng said, "earn more money and go back to your hometown in Anhui on the fifteenth day of the first month to reunite with your family."

　　In addition to strengthening the incentive mechanism for enterprises, the government has also taken action. Years ago, the relevant departments in Shenzhen made it clear that the express delivery and take-out during the Spring Festival would be subsidized by the municipal finance for each order in 1 yuan. Front-line workers in construction, tourism, sanitation, manufacturing and other industries can also receive corresponding government subsidies.

　　"Although the Spring Festival is not around my family, I am very happy to deliver the meal to the guests in time so that they can have a hot meal and have a happy year." Shen Jinfeng said.

　　Yang Lei said that nowadays, the society generally recognizes the courier brother more. During the Spring Festival, it is still relatively happy to ensure that residents receive the needed items in time and have a good year. "A package sent every day conveys a love." He said.

　　They are the epitome of tens of thousands of little brothers who stay deep in the post during the Spring Festival, contributing to the better reunion of others and working hard for their own better reunion. Shen Jinfeng said: "I believe that the good days are still behind!"

As a popular form of continuing education, more and more people choose to take the self-taught examination to improve their academic qualifications. Many people who want to improve their academic qualifications are puzzled and want to take the self-taught undergraduate course, but they don’t know the specific policies of the self-taught examination.

Summary of Registration Time and Entrance of Self-taught Exams in April 2024 by Provinces

The historic moment has come. How can TCL, which represents the "scientific strength of China", lead China’s science and technology to the world?

On January 12th, CES2024, known as "Science and Technology Spring Festival Evening", came to an end. The exhibition brings together global technology giants, attracting more than 4,000 exhibitors and more than 1,200 startup companies.

Among them, TCL, as the world’s leading intelligent terminal enterprise, appeared at CES with a brand-new "dare to act" attitude. TCL’s overall exhibition area covers an area of nearly 1,700 square meters, making it the most famous brand in China, exhibiting more than 120 innovative products and top technologies, showing its C-style. During CES, TCL also invited NFL Hall of Fame star Charles Woodson to help out by airborne, and interacted with the audience at zero distance, which narrowed the distance between brands and consumers.

This is the second year for TCL to join hands with NFL, the world’s top sports league.

NFL is the highest-level sports league in American football, and its annual feast "Super Bowl" is known as "American Spring Bowl", which is the most popular sports event in the United States today. The 57th Super Bowl attracted about 113 million spectators around the world. As a professional sports league based on American native sports, after a hundred years of development, its influence has long been not limited to the American domestic market, but also has become the first echelon sports event with global attention, occupying the chief place of the world sports league, which coincides with the development of TCL.

Since 1999, TCL has set up 32 manufacturing bases in Vietnam, Mexico and other places through TCL Industry and TCL Technology, and 46 R&D centers in Poland, the United States and other places. TCL products have maintained a high market share in developed countries including Europe and America.

In addition to the leading scientific and technological strength and the influence of brand globalization, it is highly recognized by the NFL, and it may be that both sides dare to resonate with each other.

Driven by the spirit of courage, TCL and NFL have done a great thing.

In 2024, TCL joined hands with NFL to light up the new landmark of Las Vegas — — Sphere is the world’s largest giant ball, TCL’s highly recognizable brand LOGO and NFL’s iconic giant football helmet shine in the night sky in Las Vegas, showing the extraordinary elegance of China brand to the world with unparalleled visual feast, and further demonstrating TCL’s brand technology hard power of "dare to be extraordinary" to the world.

TCL has developed from a small company producing magnetic tapes into a globally competitive intelligent technology industry group. Through TCL Industry and TCL Technology, three core industries, namely intelligent terminal, semiconductor display and new energy photovoltaic, have been widely recognized internationally.

Pay tribute to the past and move forward for the future. As one of the earliest China enterprises to go international, TCL has always practiced the concept of "globalization is localization" and achieved remarkable commercial success in overseas markets. In addition to constantly improving its overseas localization management ability, it continues to provide users with the best products and solutions, and it also benefits from its continuous exploration and investment in global brand building.

On the road of globalization, TCL continues to lay out the world’s top IP, giving the brand a strong sports gene. Up to now, TCL has more than 40 global cooperation IPs, covering rugby, football, basketball, e-sports and other sports fields. In addition to the NFL of the United States, there are also top-level global sports IPs such as the Libertadores Cup, FIBA, Brazil, Spain, Italy, Germany and Arsenal Football Club. These cooperation has become a distinctive symbol of TCL’s layout of international sports venues.

In addition to official cooperation with the NFL, TCL has also reached a partnership with three super-popular NFL teams, namely Los Angeles Lightning, Seattle Seahawks and Atlanta Falcons. Not only that, TCL also invited Justin Herbert, the quarterback of the Los Angeles Lightning Team, as the brand ambassador of TCL North America. This move will continue to help TCL establish closer emotional ties with local fans, so that more consumers can feel the charm of TCL’s cutting-edge technology, and it will also promote TCL to lay a powerful battle in the development of global sports.

In February this year, the Super Bowl, the NFL’s most important competition, is about to open, when TCL will once again make a heavy appearance, leading the new era of China brand’s overseas rise, letting the world once again see the strength and influence of China technology, and continuing to write a new chapter of "Dare to be Extraordinary" in the global market.

Weather refers to the specific state of the atmosphere near the surface of a certain area in a short time, and the phenomenon of light precipitation can be divided into 11 types. Here are how many kinds of weather are compiled by Xiaobian for everyone, and you can share them if you like!

How many kinds of weather are there?

I. Precipitation phenomena (11 kinds)

Liquid precipitation; Rain, shower, Mao Mao rain; Solid precipitation; Snow, snow showers, graupel, rice snow, ice particles, hail; Mixed precipitation; Sleet, intermittent sleet

Second, the ground condensation phenomenon (4 kinds)

Dew, frost, rime and rain

Third, visual range obstacles (9 kinds)

Fog, light fog, snow blowing, snowstorm, smoke screen, haze, sandstorm, sand blowing and floating dust

Four, lightning phenomenon (3 kinds)

Thunderstorm, lightning, aurora

V. Other phenomena (7 kinds)

Strong winds, squalls, tornadoes, dust storms, ice needles, snow and ice.

How is the weather predicted?

The first step is to collect data

The first step is to collect Ji Guang, air pressure, temperature and other data on the ground or sea surface through the equipment of some professionals. The World Meteorological Organization will further coordinate these data and finally successfully formulate a standard.

Data from meteorological satellites are more important. It can successfully collect data from all over the world and help meteorologists learn more about it. By observing and detecting clouds, we can know cloud top temperature and make predictions. Of course, ground data is more important. Specialized weather radar can obtain rainfall information, such as area and intensity.

The second step is data assimilation

Data assimilation is to combine the collected relevant data with the basic digital model, make some meteorological analysis, and get the basic answer. The final result is the optimal solution, which can not only know the temperature and humidity, but also know the pressure, wind speed and wind direction at a glance.

Step 3 Data Weather Forecast

Then the atmosphere is simulated by computer, mainly based on the data assimilation results. However, because the equation is relatively complex, only computers can make predictions.

Step 4: Output processing

After calculating the results, people can understand the meaning of the data through processing, in which errors should be eliminated and some basic adjustments should be made to the data results.

These tasks used to be done by meteorologists, but now they are much simpler, the weather forecast is more accurate than before, and meteorologists can finish their work more easily.

Step 5: Final display

The first four steps are behind the scenes, all preparing for step 5, and step 5 is also the most important step, which is to display the calculation results, so that everyone can know the future weather and make corresponding preparations.

Ancient weather forecasting methods

For thousands of years, sailors, fishermen, farmers and hunters have looked at clouds, wind, sky and objects to predict the weather and explore weather forecasting. Weather forecast has become a folk art. Ancient people looked at the sky and measured the wind and cloud. The former is the sky condition that can be observed by naked eyes and simple instruments. It not only observes the changes of the sun, the moon and the stars, but also records all kinds of past and current natural phenomena, and combines the summarized experience with current observations to make weather forecasts.
