Chapter 305

"Cheng Nuo, you're here too!" Wang Genji greeted Cheng Nuo with a smile.

"Professor Liao didn't drag me here. Cheng Nuo said to Wang Genji with a wry smile.

Cheng Nuo asked, "Senior, do you know what the professor did when he called us here?"

Wang Genji touched his chin, "This...... I don't know. ”

"Alright, you two sit down and take a look at this. Professor Liao walked over and handed the two of them a document.

Cheng Nuo and Wang Genji took it with doubts.

Cheng Nuo's eyes swept to the cover.

"Application for Research Project"?

He continued to flip back.

The content in it is indeed a template for the project application.

Project Title: Heating and current-driven simulation of electron whirlwind waves based on 3D Fokker-Planck equations

Applicants: Liao Zhixing, Ma Ziding

Affiliation: School of Mathematical Sciences, Tsinghua University, School of Physics, Tsinghua University

Application period: March 14, 2021

............

Research content and significance: Using the Fokker-Planck equation of rebound average, the numerical value of the current drive of the electron whirlwind wave is simulated, and the influence of the radial diffusion of superthermal electrons on the current drive is considered......

Keywords: Fokker-Planck equation, distribution function, electron gyration wave, heating and current drive

............

The applicant undertakes that I guarantee the authenticity of the above contents. If we get the funding, I and the members of the project team will strictly abide by the relevant regulations of the university and ensure the working hours of the research.

Finally, in the applicant's signature column, 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 from the Academy of Things.

And this project is obviously a joint research project applied for by their Academy of Mathematics and the Academy of Physics.

Cross-faculty project cooperation, which is common in Tsinghua University, is not worth making a fuss about.

After all, different disciplines are inherently interconnected. In particular, these two disciplines, such as mathematics and physics, can be described as inseparable.

For example, the physics project on electron cyclotron heating that they are holding in their hands now needs to be solved by someone from the mathematics department using the Fokker-Planck equation.

Cheng Nuo and Wang Genji closed the document at the same time, looked up at each other, and had roughly guessed the purpose of Professor Liao calling the two of them here.

On the desk, holding a thermos cup and drinking water, seeing that the two of them 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 me calling you here." ”

"Teacher, I'm ......" Cheng Nuo stood up and wanted to speak.

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

"This project was jointly applied by Professor Ma and I from the Institute of Physics, and the project application was submitted to the National Natural Science Foundation of China half a month ago, and it was successfully approved yesterday and the project funds were obtained. ”

"Compared to the previous project you studied, this research project is much more difficult. In addition, this is a cooperative project with the Institute of Physics, which also involves a lot of professional physics knowledge. ”

"Especially you, Cheng Nuo. Professor Liao looked at Cheng Nuo, "At present, you have not taken the course of college physics, and the knowledge of physics you have mastered is still limited to the high school level, which is not a good thing for you." ”

Professor Liao put his hands on his knees and tapped his index finger lightly, "I have discussed with Professor Ma, and each of our two colleges will send two students to join the research team. It is impossible to send people with no experience to do this project, it just so happens that the two of you have experience in project cooperation last semester, and there is no project to do recently, so I will report the names of the two of you, and you will come to this office tomorrow, and I will ask Professor Ma to bring the other two students over to get to know each other. ”

Listening to Professor Liao's meaning, he has already reported the names of the two of them.

Wang Genji nodded, "Professor, I'm fine. ”

Cheng Nuo raised his hand weakly, "Teacher, I have encountered some situation here." ”

Liao Zhixing gestured, "Say." ”

Cheng Nuo hesitated for a moment and slowly spoke, "Before coming to your office, I was called over by Professor Lu. He...... I was also given a place in a research project. ”

Liao Zhixing frowned slightly, "Old Lu?"

"Is it the project that asked Professor Fang to be in charge of the p-Laplacian operator and the extremely monotonic operator?" asked Liao Zhixing after a moment's thought.

Cheng Nuo nodded.

"Lao Lu is really relieved to give you such a precious place for an important topic. Professor Liao shook his head and chuckled.

"Is it rare to get a place in that topic?" Cheng Nuo really doesn't understand this thing.

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

"Of course. Liao Zhixing looked solemn, "It can be said that the importance of that topic is the first among all the projects launched in 2021 by our entire mathematics academy." What's more, Professor Fang led the team, and many people were vying for the places in the research group, even for graduate and master's students. ”

"That's it!" Cheng Nuo nodded a little pensively.

It's just that this project is so important, why is Professor Lu willing to give a place to himself? Cheng Nuo couldn't think of this.

"Professor, in that case, don't I need to join your research group on electron cyclotron wave heating and current-driven simulation based on the three-dimensional Fokker-Planck equation?" Cheng Nuo grinned.

"No, I can't. Professor Liao refused categorically without hesitation. Cheng Nuo froze, and his face instantly collapsed.

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

"Isn't it just two projects at the same time? I have a total of four projects in my hand now, isn't it much busier than you? Believe in yourself, you will definitely be able to. ”

But three of the four projects are in charge, and I have to do both of them in depth!

He wanted to say that, but in the end......

Cheng Nuo smiled bitterly and nodded hard, "Okay." ”

Wang Genji, who had been silently beside him, stood up from the sofa and pulled Cheng Nuo up, "Then professor, let's go first." ”

Professor Liao nodded with a smile, "Okay, remember to come to my office tomorrow for the meeting." ”

"Definitely, definitely. ”

Corridor outside the office.

Wang Genji poked Cheng Nuo with his elbow, "Cheng Nuo, it's okay, I've heard of Professor Fang's project, many people in our class don't have a chance to go if they want to, but I didn't expect your kid to get a place quietly!"

Cheng Nuo sighed, distressed, "No way, Professor Lu has to give it to me, and I'm embarrassed to refuse." ”
