"Cheng Nuo, you are here too Wang Ji smiles and says hello to Cheng Nuo.

"Professor Liao had to drag me here." Cheng Nuo said to Wang Ji with a bitter smile.

Cheng Nuo asked, "schoolmaster, do you know what the professor called us here for?"

Wang Ji touched his chin, "this I don't know. "

"Well, you two sit down and have a look at this." Professor Liao came over and handed a document to each of them.

Cheng Nuo and Wang Ji take over with doubts.

Cheng Nuo looks at the cover.

Application for scientific research project?

He continued to roll back.

The content in it is indeed the template of the project application.

Project Name: electron cyclotron wave heating and current drive simulation based on three-dimensional Fokker Planck equation

applicant: Liao Zhixing, Ma ziding

setting: School of Mathematical Sciences, Tsinghua University, School of physics, Tsinghua University

application time: March 14, 2021

Research content and significance: by using the rebound averaged Fokker Planck equation, the current driven numerical simulation of electron cyclotron wave heating is carried out. Considering the influence of ultra hot electron radial diffusion on current drive, the diffusion transport term is added to the equation

Key words: Fokker Planck equation; distribution function; electron cyclotron wave; heating and current drive

The Applicant promises: I guarantee the authenticity of the above information. If funded, the project team and I will strictly abide by the relevant regulations of the University and ensure the working time of research.

Finally, in the signature column of the applicant, the names of Professor Liao and another professor Ma ziding whom Cheng Nuo did not know were written.

But if Cheng Nuo's guess is right, that should be the professor over there.

And this project is obviously a joint research project applied by their several institutes and physical education institutes.

It is not surprising that this kind of cooperation is common in Tsinghua University.

After all, different disciplines are interconnected. In particular, the two disciplines, such as mathematical physics, can be described as inseparable.

It's just like the project on the physics of electron cyclotron wave heating in their hands. They need to find someone from the mathematics department to solve the Fokker Planck equation.

Cheng Nuo and Wang Ji close the document at the same time and look up at each other. They have already guessed the purpose of Professor Liao calling them here.

On the desk, holding a thermos cup and sipping water, they saw that they had finished reading the document. They gently put down the thermos cup, crossed their fingers, and said with a smile, "after reading this document, you should guess the purpose of my calling you here."

"Teacher, I..." Cheng Nuo stands up and wants to talk.

Professor Liao raised his hand and gave Cheng Nuo a slightly calm gesture, "listen to me first."

"This project was jointly applied for by Professor Ma and I of the Institute of physical education. The application for the project was submitted to the national natural foundation of China half a month ago. It was approved successfully yesterday and got the project fund."

"Compared with the last project you studied, this project is much more difficult. In addition, this is a cooperative project with the Academy of physics, which also involves a lot of professional physics knowledge. "

"Especially you, Cheng Nuo." Professor Liao looked at Cheng Nuo. "At present, you haven't taken the course of college physics, and your knowledge of physics is still limited to high school level. It's not a good thing for you."

Professor Liao put his hands on his knees and tapped with his forefinger, "I have discussed with Professor Ma that our two colleges have sent two students to join the research group. It's impossible to send someone who is totally inexperienced to do this project. It happens that you two had experience in project cooperation last semester, and have you done any project recently, so I put your names on it. You will still come to this office tomorrow. I will ask Professor Ma to bring two other students to get to know each other. "

Cut first, then play! According to Professor Liao, their names have already been published.

Wang Jiji nodded. "Professor, I'm ok."

Cheng Nuo raised his hand weakly, "teacher, I have some problems here."

Liao Zhixing indicated, "say."

Cheng Nuo hesitated for a moment, slowly opened his mouth, "before I came to your office, I was called by Professor Lu. He I was also given a quota for a research project. "

Liao Zhixing frowned, "Lao Lu?"

"Is it the subject of p-Laplacian operator and maximal monotone operator in charge of Professor Fang?" Liao Zhixing thought for a moment and asked.

Cheng Nuo nods.

"Lao Lu is really relieved to give you such a valuable and important subject quota." Professor Liao shook his head and chuckled."Is it hard to get a quota for that subject?" Cheng Nuo really doesn't understand this thing.

However, according to Professor Liao, the subject is not just an ordinary research project as he thought.

"Of course." Liao Zhixing looked solemn. "It can be said that the importance of the project theory is the first among all the projects launched in 2021 by our whole Academy of Sciences. What's more, Professor Fang is still leading the team. There are many people competing for the quota of the research group, even for graduate students and master students. "

"That's it Cheng nodded thoughtfully.

However, this project is so important, why is Professor Lu willing to give a place to himself. Cheng Nuo can't think of this clearly.

"Professor, in this case, do I not have to join your research group on electron cyclotron wave heating and current driven simulation based on the three-dimensional Fokker Planck equation?" Cheng Nuo said with a smile.

"No way." Professor Liao refused without hesitation. Cheng Nuo a stagnation, complexion instantly collapsed.

Professor Liao came over and patted Cheng Nuo on the shoulder. "There is a saying that is good, the greater the ability, the greater the responsibility."

"Isn't it just two projects at the same time? I now add this in my hand, there are four projects, not much busier than you? Believe in yourself, you can. "

But you have three of the four projects when the shopkeeper, and I want to do two topics in depth!

He wanted to say that, but in the end

Cheng Nuo grinned hard and nodded, "OK."

Wang Ji, who has been quietly beside him, stands up from the sofa and pulls Cheng Nuo up. "Professor, we'll go first."

Professor Liao nodded with a smile, "OK, please come to my office to attend the meeting tomorrow."

"Sure, sure."

The corridor outside the office.

Wang Ji poked Cheng Nuo with his elbow. "Cheng Nuo, yes. I've heard about Professor Fang's project. Many people in our class have no chance to go there. I didn't expect that you would get a place in silence!"

Cheng Nuo sighed, distressed, "I can't help it. Professor Lu has to give it to me, and I'm sorry to refuse."
