Shen Qi wrote a differential equation, and there are many different ways to solve this equation.

After the girl thought for a little, she solved the equation using infinite series, wrote a few words on the notebook, "Please review Teacher Shen", and then handed the notebook to Shen Qi.

Shen Qi glanced at the notebook, reviewed the word "√", and left.

If Shen Qi was allowed to come out of the final exam paper for the senior high school in the School of Mathematics, this question was definitely selected just now.

It is hard for a girl to give the correct answer in a short period of time, but Shen Qi can't say anything, she should do whatever she likes.

Students who love to sleep in class are either poor students who have lost their knives or talented students.

After finishing the day's work, Shen Qi changed into sportswear and went to the May Fourth Stadium to run.

There is a runner who is Associate Professor Xu Zhou of the Academy of Marshal.

Xu Zhou and Shen Qi run together to exercise to accumulate physical fitness.

After running 5,000 meters, Xu Zhou could keep up with Shen Qi's pace.

After running to 10,000 meters, Lao Xu could not run anymore, and Shen Qi was still running.

Shen Qi ran 12,000 meters and came to Xuzhou to sit down.

Xu Zhou unscrewed the bottle cap of the mineral water and handed it to Shen Qi: "Professor Chen, you can run so hard, you can understand it."

"Old Xu, when will you go?" Shen Qi asked after taking the mineral water.

"Next month." Xu Zhou's scientific expedition project has passed the internal review of Yan University, and it should only be a matter of time before it is approved by the ministries and commissions.

"What is the first stop?" Shen Qi was very interested in Lao Xu's scientific research project.

"Sanjiangyuan." Xu Zhou is an expert in atmospheric physics. He is very grateful to Shen Qi. Shen Qi's remarks helped his project pass the on-campus review and enable the scientific examination to be carried out as planned.

"The Sanjiangyuan is a good place, and there are many famous snow-capped mountains there. Will you have a mountaineering plan for this scientific expedition?" Shen Qi asked again.

Xu Zhou replied: "No, we are not professional enough to climb. We will collect data at the foot of the mountain this time, such as atmospheric, hydrology, geology and other data. In fact, my team is like a navy, and we are better at working in the ocean."

Xu Zhou's scientific expedition project this time is to conduct in-depth research on global warming issues.

Their scientific expedition route starts from the Sanjiangyuan Plateau area, heading eastward and finally enters the Arctic Circle waters.

The Qinghai-Tibet Plateau is considered a heat source in the northern hemisphere in summer and a cold source in winter.

Global warming, Arctic glaciers melted on a large scale, and countries in the northern hemisphere experienced abnormal high temperatures in summer. How this series of abnormal phenomena can be improved is the topic of Xu Zhou and others.

"The Qinghai-Tibet Plateau is an air conditioner in the northern hemisphere, but now there is a problem with the air conditioner. Lao Xu, your scientific expedition is quite meaningful and we look forward to you to make major research progress." Shen Qi very support Xu Zhou's scientific expedition project.

"Satellite inversion combined with numerical mode analysis is advanced, but there are still some errors in satellite data and computer numerical modes, especially the ability to describe complex lower surfaces of the plateau is obviously insufficient, so field scientific research still has irreplaceable scientific value. Regarding the issue of global warming, its specific physical processes and dynamic mechanisms, I really want to ask Professor Chen for advice."

Xu Zhou drank a sip of mineral water and said, "I have read all the papers and monographs you wrote. There are two articles I have repeatedly studied. One is "On Complexity" you wrote when you were working in Princeton. This article has particularly in-depth analysis and predictions on turbulence and chaos theory, which fascinates me. The other is the analysis of n-s equations you published last year, and you give understanding methods and general solutions, while I am more concerned about the specific application research on the subsequent application of n-s equations."

Shen Qi smiled and said, "Then see you in Sanjiangyuan."

Xu Zhou asked: "Are you going out with our scientific expedition team or have other plans?"

"Your scientific expedition team implements the established plan, don't worry about me. If conditions allow, I will go to find you. Come, Lao Xu, run another 5 kilometers." Shen Qi pulled Xu Zhou to continue running. The scientific expedition is a job of combining physical strength and intelligence. Without a strong body, not only will the scientific expedition task not only cannot be completed, but there may also be problems during the scientific expedition process.

Lao Xu gritted his teeth and ran for another 5 kilometers. He was so tired that he had cramps that he couldn't run anymore and lay on the lawn to rest.

Shen Qi ran a half-marathon in one breath, and he still has the courage to do so.

As the sun sets, the students are over, and the number of college students coming to exercise in the stadium is gradually increasing.

There is a running team that is quite distinctive. More than a dozen of them are wearing uniform white T-shirts, and the logo is Yandashan Eagle Club.

Each member of the Shanying Club carries a bag with 15 kilograms of water in it. They carry a load and run around in circles.

There are two most famous clubs in Quanyan University, one is the League School and the other is the Shanying Society.

The core activity of Shanying Club is mountaineering in summer, and the peaks above 6,000 meters in China have basically been conquered by Shanying Club.

During the summer vacation in July and August this year, Shanying Club will continue to carry out summer mountaineering activities.

May and June are a very important mountaineering preparation stage. Shanying Club adopts the old way to lead new things, running at Yanda, or running from Yanda to Xiangshan, and climbing all the way to Xianglu Peak.

More professional training was carried out at Huairou Rock Climbing Base, and the trial ground for newcomers was 3,000 meters high Wutai Mountain Beitai.

It is not difficult for Yan University students to enter the Shanying Club, but the difficult thing is to join the Shanying Club mountaineering team.

The designated location for the winter training of Shanying Society is Wutai Mountain Beitai. After this newcomer village, the newcomers are qualified to join the Shanying Society mountaineering team and challenge the more difficult and high-level snow-capped mountains.

As Shen Qi ran, he ran into the team of Shanying Society.

"Oh, Professor Shen!" The members of the Shanying Society discovered Shen Qi who was infiltrated into the team.

"Friends, friendly forces." Shen Qi adjusted his breathing rhythm and signaled that the training team of Shanying Society should treat him as air, ignore him and let him go.

It is not easy to run with 15 kilograms of water, but none of the members of the Shanying Club complained about being tired because they knew that it was normal to march with dozens of kilograms of tents and equipment on their backs.

The members of Shanying Society come from various departments of Yan University, mainly undergraduates. After a wave of weight-bearing run, they stopped to rest.

The twelve trainees are mostly boys, and there are three girls.

Shen Qi sat down next to a girl and said to the girl: "Classmate, you can see you everywhere. Are you a member of Shanying Society?"

The girl was the one who was dozing off in class in the morning. She nodded and said, "Yes, my name is Zeng Lina, a freshman in finance and mathematics at the School of Mathematics. Please give me some advice."

"Student Linna, since you are from Shanying Club, I'm relieved." Shen Qi knew the recruitment standards of Shanying Club. Those who failed the course will not recruit students, those who did not have the ideological and moral standards will not recruit, and those who were spoiled will not recruit.

Zeng Lina's ability to join the Shanying Club and join the June training team shows that she has excellent academic performance and has not failed the subject in her freshman year at least. She should have passed the Wutai Mountain Winter Training Test, otherwise she will not be able to join the June training team, which shows that she has strong perseverance and high double resistance.

There are many academic masters at Yan University. The reasons for joining the Shanying Society are strange. The current president comes from the Chemical Academy. His grades are so good that he is so good that he is not allowed to take several courses. He is really bored, so he joined the Shanying Society to spend time.

Mountaineering is dangerous, and few students join the Shanying Club for the sake of exercise. The more suitable sports clubs are the running associations, Table Tennis and Badminton Association, and Swimming Association.

"Why did you join the Shanying Club?" Shen Qi asked Zeng Lina.

Zeng Linna: "The president said that the mountaineering team of Shanying Club must have female members, preferably a beautiful and skillful young lady, so I will join."

"This reason is particularly sufficient." Shen Qi smiled and asked again: "What is your challenge goal this summer vacation?"

Zeng Linna looked into the distance and said yearningly: "Ma Qinggangri."
