It was detected that Xiaobai was a bladder blockage, and the treatment cost was more than 800, and the money was all from Gu Ningshan......

It should be a rich man.

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

Glancing at Xiaobai, who had a much more comfortable expression in the cat's bag, Wu Bin asked, "The doctor said that it still has to take medicine every day, can you take care of it?" ”

Gu Ningshan nodded: "I know a senior sister who is willing to help adopt stray cats, I'll go to her later, and when Xiaobai is ready, I'll go to the group to help her find someone to adopt." ”

"Oh, that's good."

"Anyway, why did Xiaobai take the initiative to approach you? I've been feeding it for days, but it runs when it sees me approaching it. Gu Ningshan's little face was puffed up, and her words were full of disbelief.

Wu Bin: "I've always been very attractive to cats since I was a child, and cats generally like to stick to me. ”

Looking at Wu Bin, who spoke casually, Gu Ningshan was full of envy.

Sitting on the bus on the way back, 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.

Therefore, the two of them deduced the second law of thermodynamics from the two customary formulations of Carnot's theorem and the first law of thermodynamics, revealed the equivalence of Carnot's theorem and the second law of thermodynamics, gave a new derivation method of thermodynamic entropy and Maxwell's relation, summarized the various applications of Carnot's theorem, and objectively evaluated the application value of Carnot's theorem.

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

Wu Bin said and took out a notebook and pen from his schoolbag, and said while writing: "Specifically, the shooting system works between two heat sources with a temperature difference of ΔT→0 to complete a reversible Carnot cycle. This results in an infinitely flattened quadrilateral in the p-V diagram......"

"You're a competitor." Gu Ningshan looked at Wu Bin, who was excited, and suddenly asked.

"Well, it's a physics competition." Wu Bin nodded, and then continued: "If you change the volume ΔV→0 again, then the quadrilateral will shrink to an infinitesimal parallelogram, so that it is easy to calculate. ”

Gu Ningshan nodded and asked, "Have you learned how to use Carnot's theorem to calculate the heat emitted by a reversible battery during isothermal charging, and to balance the internal energy density of radiant photon gases?"

"Huh? Is there still such an app!? Wu Bin stared at Gu Ningshan, his eyes lit up.

"Poof...... Hahaha. Looking at Wu Bin's eyes, Gu Ningshan suddenly laughed.

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

Gu Ningshan shook her hand and said, "It's nothing, it's nothing, I just think you are quite similar to a person." ”

After speaking, Gu Ningshan found that the car had arrived at the station, so she pulled Wu Bin and got off the bus together.

"Thank you for your help today, I have to send Xiaobai to Senior Sister first." After getting out of the car, Gu Ningshan made the cat bag and took it in Wu Bin's hand and said.

"Oh...... That's fine. ”

Looking at Wu Bin's reluctant eyes, Gu Ningshan smiled and took out her mobile phone and said to Wu Bin: "Why don't you add a WeChat, if you want to see Xiaobai, I can also send you some photos." ”

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

After adding friends, Gu Ningshan waved at Wu Bin and left, while Wu Bin was full of melancholy.

"I don't know if I can explain the application of Carnot's theorem in the field of batteries on WeChat......

Seeing that it was almost time for dinner, Wu Bin felt that he had almost finished feeling the University of Science and Technology, so he took out the phone and called Professor Song Nanfeng.

"Hey, Wu Bin, you're here?" Song Nanfeng picked up the phone and asked.

Of course, Wu Bin had told Song Nanfeng that he was coming today before he came, but he didn't say the specific time.

"Well, at the school gate."

"Okay, you wait a minute, I'll pick you up."

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

After greeting Wu Bin, Song Nanfeng took him to the bicycle rental point on campus of HKUST 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 campus of HKUST," riding past the mushroom pavilion, Wu Bin couldn't help but ask curiously after finding that there were still no students inside.

Song Nanfeng smiled after hearing this, and said, "Want to see a place with a lot of people?" Okay, I'll take you. ”

When passing by a small road called Red Specialist Road, Song Nanfeng introduced to him that it was based on the school motto of HKUST "Red Specialist Goes Together, Rationality and Reality Blend".

"Sounds like a sense of mission."

"Hey, you're on the point, the University of Science and Technology was built as soon as it was proposed, and it opened that year, and the students and teachers really have a strong sense of mission."

While visiting and chatting, Song Nanfeng took Wu Bin to a playground that covers a wide area, and here, Wu Bin finally met those students of the University of Science and Technology who he "missed".

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 major in sports, we don't have sports specialties, but in various sports competitions, we have won many awards, and last year our dragon boat team also broke the 700-meter track record of C9 University. ”

Wu Bin still heard the term C9 university from Li Yan, which is a nine-university alliance composed of 9 top universities, including Jingbei University, Jinghua University, Aurora University, Huhai Jiaotong University, Jinling University, Zhejiang University, Huaguo University of Science and Technology, Heerbin University of Technology, and Daxing Jiaotong University.

Substantive activities are often carried out between the alliances, such as student exchanges, seminars, summer camps, etc.

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

"That's really ...... Unexpectedly. Wu Bin sighed after thinking about it.

"Why, I thought that all the students at HKUST were nerds? The kind that crashes into trees when walking? ”

"Not really." Wu Bin waved his hand, "It's just that the students I imagined are indeed quite weak." ”

"Hahaha." Professor Song Nanfeng laughed for a while, "Everyone practices physical education for a better body, because then we can do better academics." ”

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

"I think you're quite strong and fit for our school." Song Nanfeng pinched Wu Bin's arm muscles and said with a smile.

Wu Bin smiled and didn't say anything.

Song Nanfeng was not in a hurry, and said: "There are three places with the most students in the University of Science and Technology, one is the study room, and the other is the gym and gymnasium, oh yes, by the way, our gym is free." ”

"What about the third?" Wu Bin asked.

"Of course it's the library, do you want to check it out?"

Wu Bin was immediately interested when he heard this, and stepped on the bicycle and said eagerly: "Then ask the professor to lead the way." ”

PS:Alas,Last month, when there were few updates, readers were spraying updates.,Now the update is normal, I thought I could be praised for two sentences.,It turned out to start spraying boring content again.,Water.,It's boring.,This session of readers is really hard to serve......

Tell me, what about me, just a glass heart, every chapter, is written by me seriously, if you think it's water, it's cheating your subscription, then you do me a favor, for the sake of this book, which allows you to see 300,000 words, don't say anything about this chapter of real water, I've been really bored lately, and I'm going to choke on it.,Delete the book directly.,Thank you.。
