Scholar’s Starry Sea

It was detected that Xiaobai had a bladder congestion problem. The treatment cost was more than 800, and the money was all from Gu Ningshan. After she saw the price, she still used the mobile phone to consume it. In terms of actions, Wu Bin felt that this child...

should be a rich man.

After listening to the doctor's instructions, the two left the pet hospital together.

Looking at Xiaobai, who has a much more comfortable expression in the cat bag, Wu Bin asked: "The doctor said that he still needs to take medicine every day. Can you take care of him?"

Gu Ningshan nodded: "I know a Senior Sister who is willing to help adopt stray cats. Later I will find her. When Xiaobai is ready, I will go to the group to help him find someone to adopt."

"Oh, that's good."

"Why did Xiao Bai take the initiative to approach you? I have been feeding him for several days, but he ran when he saw me approaching him." Gu Ningshan The face was bulging, and the words were full of dissatisfaction.

Wu Bin: "I have always been a cat through childhood, and most cats like to stick to me."

Looking at Wu Bin with a casual tone, Gu Ningshan was full of envy.

Sitting on the bus on the return journey, Gu Ningshan suddenly chatted with Wu Bin about the relationship between the thermal value of Carnot's theorem and the second law of thermodynamics, which aroused Wu Bin's great interest.

So the two derive the two usual expressions of the second law of thermodynamics from the use of Carnot's theorem and the first law of thermodynamics, revealing the equivalence of Carnot's theorem and the second law of thermodynamics to give The new derivation method of thermodynamic entropy and Maxwell relationship summarizes the various applications of Carnot theorem and makes an objective evaluation of the application value of Carnot theorem.

"In fact, there is no need to use the state function S. Many problems can be solved by only relying on Carnot's theorem and the first law of thermodynamics."

Wu Bin said that he took out his book from his schoolbag. And the pen, while writing, said: "Specifically, it is to shoot to the system and work between two heat sources with a temperature difference of ΔT→0 to complete a reversible Carnot cycle. In this way, an infinite flat is formed in the p-V diagram. The quadrilateral..."

"Are you a contestant." Gu Ningshan asked Wu Bin, looking at Wu Bin with excitement.

"Well, I participated in the Physics competition." Wu Bin nodded, and then continued: "If the volume is changed by ΔV→0, the quadrilateral will shrink into an infinitesimal parallelogram, so It’s easy to figure it out."

Gu Ningshan nodded, asked: "Then use the Carnot theorem to calculate the heat released by a reversible battery during isothermal charging, and to balance the internal energy density of the radiated photon gas. Have you learned it?"

"Eh? Is there any such application!?" Wu Bin stared at Gu Ningshan with his eyes glowing.

"pu... hahaha." Seeing Wu Bin's eyes, Gu Ningshan suddenly laughed.

"What's wrong?" Wu Bin asked inexplicably.

Gu Ningshan shook his hand and said: "Nothing. Nothing. I think you look like a person."

After Gu Ningshan found that the car had arrived at the station, he pulled Get out of the car with Wu Bin.

"Thank you for your help today. I have to send Xiaobai to Senior Sister first." After getting off the bus, Gu Ningshan took the cat bag into Wu Bin and said.

"Oh...that's OK."

Looking at Wu Bin's eyes full of dissatisfaction, Gu Ningshan smiled and took out his phone and said to Wu Bin: "Why don't you add a WeChat? Well, if you want to see Xiaobai, I'll send you some photos."

"Okay." Wu Bin nodded, scanned Gu Ningshan's QR code.

After adding friends, Gu Ningshan moved towards Wu Bin waved his hand and left, Wu Bin was full of melancholy.

'I don’t know if we can explain the application of Carnot's theorem in the battery field on WeChat...'

Seeing that dinner is approaching, Wu Bin thinks it’s almost the same. After experiencing the University of Science and Technology, I took out the phone and called Professor Song Nanfeng.

"Hey, Wu Bin, are you here?" Song Nanfeng answered the phone and asked.

Before Wu Bin came, of course, he had told Song Nanfeng that he was coming today, but he didn’t say the specific time.

"Well, it's at the school gate."

"Well, you can wait a moment, I will pick you up."

About ten minutes have passed. , Song Nanfeng rode a yellow bicycle to the school gate.

We said hello to Wu Bin, Song Nanfeng took him to the bicycle rental point on the University of Science and Technology campus to help him borrow a bicycle, and then began to visit the campus.

"Professor Song, I have a question, why are there so few students on the University of Science and Technology campus......" Cycling past the Mushroom Pavilion, Wu Bin couldn’t help but curiosity after discovering that there were still no students inside. Asked.

Song Nanfeng listened to laughed and said: "Want to see a crowded place? Okay, I will take you there."

When passing a trail called Hongzhuan Road, Song Nanfeng introduced to him that this was based on the University of Science and Technology's motto of "Going forward with red and professional, blending theory and practice".

"It sounds like a sense of mission."

"Hey, you're on the point now, University of Science and Technology, it was as soon as it was proposed. It was built immediately and the school started that year. The students and teachers have a strong sense of mission."

While visiting and chatting, Song Nanfeng took Wu Bin to a place with a very large area. A wide playground, and here, Wu Bin finally met those University of Science and Technology students who he "want to his heart".

Looking at the athletes running on the playground, Song Nanfeng introduced to Wu Bin: “Our University of Science and Technology...Although we don’t have a sports major, we don’t have any specialties in sports, but various In sports competitions, we have won many awards. Last year, our dragon boat team broke the 700-meter track record of C9 colleges."

The term C9 colleges, Wu Bin still heard from Li Yan. It is a nine-university alliance composed of nine Peak universities including the University of Beijing, Tsinghua University, Aurora University, Shanghai Jiao Tong University, University of Jinling, Zhejiang University, China University of Science and Technology, Heerbin University of Technology, and Daxing Jiaotong University.

Various substantive activities are often carried out between the alliances, such as exchanging students, holding seminars, and conducting summer camps.

Now after listening to Professor Song Nanfeng's words, Wu Bin understands that there seems to be a lot of sports competition among the nine schools.

"This is really...didn't expect." Wu Bin thought about it and said with emotion.

"Why, I thought that all the students at the University of Science and Technology were nerds? The kind that walked into trees?"

"Nothing." Wu Bin waved his hand, "It's just that the Bookworms in my imagination are indeed very weak."

"hahaha." Professor Song Nanfeng laughed, "Everyone is practicing sports for better Body, because of that, it can do better academic work."

"Well, it makes sense." Wu Bin nodded.

"I think your body is also quite strong, suitable for our school." Song Nanfeng squeezed Wu Bin's arm muscles and said with a smile.

Wu Bin laughed, no words.

Song Nanfeng was also unhurried for a while, and said: “There are three places with the most students in the University of Science and Technology. This gym is free."

"What about the third one?" Wu Bin asked.

"Of course it is the library, do you want to see it?"

Wu Bin immediately became interested when he heard that, stepped on the bicycle and said eagerly: "Then please professor Lead the way."
