See you for a long time! What’s wrong with my female friend at CCB staying up late with me to watch the Champions League？

See you for a long time! My female friend in CCB stayed up all night watching the Champions League with me, and brought her computer … The reason is found!

I’ve been watching football for more than twenty years. No matter it’s 8: 00 or 4: 00 a.m. Beijing time, female friends only watch her "husband" YiBo or sleep in her sleep. But in recent months, they have asked me about the schedule of the Champions League every week, and ordered take-away barbecue and potato chip cola … Happiness came too suddenly. Later, I saw a blogger’s financial analysis of Milan’s duo on the Internet.

This season’s Champions League, the Milan duo like to come to China for a light, all the way to the opening of the lucky burst! AC Milan Group Stage was a group with Chelsea, Red Bull Salzburg and Dinamo Zagreb, and successfully joined hands with Chelsea to qualify. However, Inter Milan unexpectedly broke through from Bayern Munich, Barcelona and Bilsen, and forced Barcelona to play the Europa League. In the quarter-finals, Naples and Benfica were eliminated and both advanced to the quarter-finals. After the semi-finals, it is expected that Milan’s Champions League income will exceed 100 million! (The following is the calculation table of this blogger)

Counting the match-day income, the Milan duo will each have six Champions League home games this season. According to the average single home game of 6 million euros, it will generate at least 36 million tickets. Let’s take a test. Milan’s two men share a stadium, but both sides have different names for the stadium. Milan is called San Siro. Do you know what Inter is called?

In the semi-finals, the bonus increase of Milan Shuangxiong mainly comes from three parts: promotion bonus+semi-final ticket+change of market pool bonus, and this part of bonus will bring at least 21 million euros extra because Milan Shuangxiong is promoted to the semi-finals!

To sum up, Milan’s total income in the Champions League this season will exceed 110 million!

According to foreign media reports, China Construction Bank has recently sued the eldest son of Inter Milan President Zhang Kangyang in an Italian court, demanding to recover 250 million yuan in arrears. At the same time, the Italian court is required to cancel the salary immunity of Zhang Kangyang Club! It can be seen that these financial tycoons have gone overseas with the money of China people and investors, and the relevant institutions in China can’t do anything about it. I bought several thousand yuan of wealth management products from CCB! No wonder, female friends are so concerned about the Champions League. It turns out that they have to assess KPI …

According to the relevant regulations of Italy, Inter Milan needs to account for 60 million yuan before June 30 this year. Zhang Kangyang was in big trouble after his attempt to pay off the debts with Zhang Wei failed last summer, and it was even rumored that he was eager to get rid of Inter Milan to cash out. Now, the extra income from going through three levels is just in the early 60 million.

Did you really come to China to have a light? Not a penny worse!

But even if we are lucky enough to pass this season, we will face the same financial crisis before the start of next season. After Juventus successfully claimed the deducted 15 points, Inter Milan’s ranking in Serie A has dropped to the sixth place. If it fails to qualify for the Champions League next season, or if it doesn’t go far in the Champions League, Inter Milan’s alarm has not been lifted. At the end of the season, Zhang Kangyang will consider whether to cash out in the summer by taking advantage of Inter Milan’s highlight in the Champions League this season, or sell several core players such as lautaro and varela to maintain financial balance.

The marathon is hot, and female runners have half the credit.

Inscription: With the development of everything in a good direction, the marathon that has been silent for three years has begun to recover. It is not difficult for us to find that many marathons have started at the same time in recent weekends. From the live footage, we have seen everyone’s enthusiasm for participating in the marathon and some inspirational stories, such as visually impaired people, disabled people and mothers pushing their children to run, which are conveying positive energy to us. The biggest worry for runners now is that they can’t win the lottery in the race, because there are too many people who have signed up. Sometimes hundreds of thousands of people will compete for tens of thousands of places. Think about how interesting it is for tens of thousands of people to compete in the same field.

The marathon is very hot, and everyone is happy to take part in the marathon, mainly because they see some benefits of the marathon, such as enhancing our self-confidence, satisfying our vanity, getting rid of our fat, etc. These are only a small part of the reasons, because everyone has different starting points, so 100 runners can give 50 reasons. In this group of runners, the proportion of female runners is very small, which can be seen from the registration of some marathons. For example, after you finish running, your certificate of completion will tell you the ranking of the same age, gender and overall, which can be calculated by simple addition and subtraction.

Although the number of female runners is relatively small, they are a beautiful "landscape". They are not only sexy, such as short shorts, but also some of them are in good shape, so this has stimulated some male runners’ desire to run. I believe that no male runner can refuse to compete with beautiful female runners, run together, and catch up with each other. Even if you are a roadside refueling audience at the marathon, you may be eager to move. Therefore, it is no exaggeration to say that we female runners have half the credit for the hot marathon. If we replace our beautiful little sister with an aunt, everyone’s enthusiasm for participating in the marathon will definitely fade.

This is the importance of women, which is reflected incisively and vividly in all walks of life, and running is no exception. However, we female runners need to be reminded that we also need to "lead an honest and clean life", and don’t deliberately dress too sexy to attract attention. It is necessary to protect our privacy. We should also remind our male runners that although we have a strong competitive spirit, we should also take part in the marathon properly, and it is absolutely suitable for marathon. At the same time, we also want to apologize to those who have caused inconvenience because of the road closure of the marathon. I hope you will have the opportunity to participate. Running is really a very interesting and satisfying thing.

The Nets are too weak! Harden’s depression didn’t hinder the 76 ers’ 4-0 promotion and only hoped that the Great would recover.

Despite Harden’s poor state and Embiid’s absence due to injury, the 76ers beat the Nets 96-88 in the fourth game of the playoffs, sweeping the Nets 4-0 to reach the Eastern Conference semifinals, becoming the first team to break through the first round of the playoffs this season. The 76ers swept their opponents in the playoffs for the first time since the 1990-91 season. However, the 76ers also have a hidden danger, that is, Embiid is troubled by a knee injury, and they are eager for Embiid to recover before the Eastern Conference semi-finals.

Sweeping the Nets to Advance, Two Helpers Rise

It’s not that the 76ers performed too well, but that the Nets were too weak. The Nets sent Owen and Durant away, but they didn’t get all-star players. The new core was too young to bear the responsibility of leadership. He made 6 of 18 shots and got 14 points and 5 rebounds. Bridges was regarded as Durant’s successor by the Nets. However, his talent is not as good as Durant’s, and he used to be a role player in the Suns. When he came to the Nets, he has not fully adapted to the role of leader. Bridges needs a good polish during this year’s offseason.

The Sun’s Cameron Johnson is still too young, and Dinwiddie’s upper limit is not high. The 76ers can still beat the Nets without Embiid.

Harden was in a low state, making 4 of 18 shots and getting 17 points, 8 rebounds and 11 assists. But Maxi scored 16 points and 8 rebounds, and Paul Reid scored 10 points and 15 rebounds. Tobias Harris scored 25 points and 12 rebounds. Maxi and Harris rose in the first round of the playoffs, and they were the top two players in the team, surpassing Embiid and Harden.

Beard averaged 17.3 points, 5.5 rebounds and 8.8 assists in the playoffs, shooting 34.3% from the field and 42.4% from three points. Embiid played three playoff games, averaging 20.0 points, 11.3 rebounds and 4.0 assists per game, while he averaged 33.1 points, 10.2 rebounds and 4.2 assists per game in the regular season, making him the scoring champion this season. Neither of them performed as well in the playoffs as in the regular season.

Maxi was the scoring champion of the 76ers in the first round of the playoffs, averaging 21.8 points per game. Tobias Harris averaged 20.3 points in the playoffs, making him the second leading scorer of the 76ers. Embiid averaged third in the 20.0 team and fourth in Harden’s 17.3 team.

Harris saved 76 people in this game. Harden praised Harris after the game: "He played great, man. He has been attacking the basket, finishing near the basket, making three points and defending well. This is a special game for him and we need him. "

Next, the 76ers need to prepare for the next round of competition. Their opponents in the Eastern Conference semifinals will be the winner between the Celtics and the Hawks.

Take a week off and look forward to the emperor’s recovery.

Embiid is not only the scoring champion of the 76ers this season, but also a popular candidate for MVP this season. The 76ers need Embiid to stay healthy if they want to go further in the playoffs. In an interview after the game, Harden said: "Obviously, today is very important for us, so that our big man can recover. This is the first priority." The 76 ers swept the Nets to advance, which is equivalent to buying Embiid at least one week’s recovery time.

Defender Maxi also talked about Embiid’s knee injury after the game: "The victory originated from Joel (Embiid). For him, he is the leader of this team. He encouraged his teammates before the game and wished us luck. We are grateful to him for this, and we need him to recover. "

No Embiid’s 76ers can beat the Nets, but it is almost impossible to break through in the second round. The Nets are actually the weakest team in the playoffs this year.

So what’s the situation with Embiid? After the elimination of the Nets, 76ers coach Rivers talked about Embiid’s injury, saying that Embiid has a maximum of 50% possibility to prepare for the second round of the playoffs. In addition, on the day before the Fourth World War, Rivers also talked about Embiid’s physical condition.

"He feels a little sore at the back of his knee, which is actually quite scary. It was swollen, so we did an MRI. Usually, there is basically no problem with the feedback results of nuclear magnetic resonance, but the results of this inspection are not particularly good. " Rivers said. If Embiid can’t recover in time, then the 76ers are likely to stop in the second round.

On the 10-kilometer runway, two athletes with a speed of 15 or 20 kilometers start at the same time, and seek the meeting time.

Problem description:

Suppose there is a 10-kilometer-long runway, and two athletes start from the same starting point at the same time. One athlete has a speed of 15 kilometers per hour and the other athlete has a speed of 20 kilometers per hour. So when and where did the two athletes meet?

Problem solving process:

First of all, you need to know that the condition for two athletes to meet is that they run the same distance and have the same time. Therefore, we can solve it by setting variables and listing equations.

Suppose one of the athletes runs for x hours, then the distance he runs is 15x kilometers; The other runner ran 20(x-0.5) kilometers, because he was faster than the first runner, so he ran 0.5 hours less. Because they run the same distance, the following equation can be obtained:

15x=20(x?0.5)

After simplification, you can get:

Therefore, the two athletes will meet in two hours. The location where they met can be obtained by substituting the formula:

15x=30

Therefore, the two athletes will meet 6 kilometers before the 10-kilometer finish line.

Analysis:

This problem needs to be applied to basic kinematics knowledge, such as the relationship between speed, time and distance. By setting variables, listing equations and solving them, the answer to the question can be obtained.

In addition, this problem can also be solved from a more intuitive perspective. The distance difference between the two athletes is 5 kilometers per hour, that is, the first athlete can only walk 5 kilometers per hour. Because they started in the same position, when the second athlete caught up with the first athlete, the first athlete actually only walked half of the 10 kilometers, that is, 5 kilometers. Therefore, the two athletes will meet at the sixth kilometer, half of the 10 kilometers before the finish line.

In a word, although this problem looks simple, it contains profound physical significance and practical application.

Not afraid of the big Paris single-core operation, but afraid of the boss’s control variables.

I am not afraid of the single-core operation in Paris, but I am afraid that Boss Mei will control the variables. If it is an accident that the mother director was injured after missing a penalty in the opening stage, it is more like a silent demonstration that Messi led the team to complete the goal in the second half.

Remember the fans’ cynicism about Messi after losing in the last round in Paris? The team lost the game, but the fans pointed their finger at Messi. Some people doubted Messi’s ability to lead the team. Some even said that Messi had no desire to win after playing the World Cup and was completely flat in the club. However, in this game, without Mbappé, Messi played the level of single-core combat when playing in the World Cup. His excellent overall situation and superb passing repeatedly tore open the opponent’s defense line, and finally helped Barley win the game.

Boss Mei’s panting expression after the game shows that he didn’t lie flat as people say, but tried his best. No wonder some people say that they are not afraid of the single-core operation in Paris, but they are afraid that the coal boss may strengthen the control variables. Messi’s core position in the team is the key to winning in Greater Paris. Let Qiu Wang become Mbappé’s deputy, which will only destroy the last green glory of Boss Mei.

VCSEL ＂Core＂ Strength and Ruishi Technology Help the Localization of Laser God Smart Lidar to a Higher Level.

Recently, Radium Intelligence and Ruishi Technology have reached a friendly strategic cooperative relationship. Based on the principle of mutual benefit, mutual trust and win-win cooperation, the two sides have launched deep vertical industrial chain cooperation in the field of VCSEL lidar.

Hu Xiaobo, Chairman of Radium Intelligent, signed a strategic cooperation agreement with Wang Yang, Chairman of Ruishi Technology.

VCSEL chip has the advantages of high photoelectric conversion efficiency, small divergence angle, good beam quality, good wavelength stability, high reliability, low threshold current, low power consumption, small size and easy integration, and the cost of mass production can be controlled, so it is the best choice for vehicle-mounted hybrid solid-state laser radar and FLASH laser radar. VCSEL chip helps the vehicle-mounted hybrid solid-state laser radar to achieve longer detection distance, higher sensing accuracy and meet a series of stringent requirements such as human eye safety. It can also help FLASH lidar to achieve a more flexible and wide field of view, and it has a great cost advantage.

Because the manufacturing process of VCSEL chips is demanding and the mass production is difficult, most VCSEL chips on the market are monopolized by international manufacturers. However, in recent years, domestic VCSEL chips are rising with a rapid momentum, and "Ruishi Technology" is such an enterprise that can meet the demand of "looking for domestic substitute products".

"Ruishi Technology" has broken through the bottleneck of the existing technology, not only has the industry’s top chip design ability and large-scale delivery ability, but also has built a rare VCSEL chip vehicle level test and reliability certification laboratory in China. The technological advancement has reached the international first-class level, and related products have passed the vehicle level certification and have been mass-produced on the vehicle.

Hu Xiaobo, Chairman of Radium Intelligent, signed a strategic cooperation agreement with Wang Yang, Chairman of Ruishi Technology.

Radium Intelligence is the earliest lidar company in China that began to lay out vertical industrial chain resources, and it is also a state-level high-tech enterprise with pure domestic investment. It has always regarded "building all-domestic lidar" as an important strategic direction for enterprise development, devoted itself to improving the performance of domestic lidar, and laid out the R&D investment of FLASH lidar. The strong alliance with Ruishi Technology means that China’s laser radar transmitter chip technology is no longer restricted by international factors, and the domestic technology level has also reached the international advanced level, and it has the cost advantage of localization, laying a solid foundation for the large-scale application of high-performance laser radar.
