Starting from a top student and marching towards the sea of ​​stars

Chapter 14 You will answer quickly
Such emotions made Yang Lianhua hope from the bottom of his heart that Shengzhou University can become better, and naturally hope that Shengzhou University can emerge more talents.

"Don't worry, Teacher Yang, I will definitely treat Ning Chen like my own graduate student."

The next day, He Sheng informed Ning Chen that he had completed the inspection of Ning Chen's research results and confirmed that the entire research results were correct, and invited Ning Chen to come to the laboratory for a detailed discussion at night.

Ning Chen was also a little excited after receiving He Sheng's affirmative news.

This marks that Ning Chen is a small step closer to successfully publishing a paper.

After dinner in the evening, Ning Chen went to He Sheng's laboratory.

After entering He Sheng's laboratory, Ning Chen discovered that besides He Sheng, there was another older teacher in the laboratory.

"Mr. Yang, this is the classmate Ning Chen I told you about."

"Hello, classmate Ning Chen."

"Hello, Teacher Yang!"

While saying hello, Yang Lianhua got up while looking at Ning Chen.

Yang Lianhua's first impression of Ning Chen was very good. Ning Chen's image is very good. He is 1.8 meters tall, has a very standard figure, and is also very handsome.

In addition to a good image, Ning Chen's temperament gave Yang Lianhua a deeper impression.

When normal students meet Yang Lianhua for the first time, they will more or less show a little timidity.

This is also a normal reaction for students to meet a professor for the first time. After all, students will naturally feel nervous in front of a senior professor, even master and doctoral students.

But Ning Chen seemed very confident. This kind of confidence was not pride, but an affirmation of his ability.

"Ning Chen, I heard Teacher He say that you made these research results by yourself. I'm very curious, how did you come up with the idea to study these things?"

Yang Lianhua did not directly ask Ning Chen about the academic issues in the research results, but first asked about the motivation.

"Actually, to a large extent, it was by accident. When I was learning various mathematics knowledge, I learned about the existence of the Sine-Gordon equation. At that time, I was still on a very superficial level. But one night, I suddenly thought of something, and felt that I could use a brand-new method to obtain the exact solution of the Sine-Gordon equation..."

Ning Chen's words were naturally carefully organized, and this was also to allow himself to give a more reasonable explanation when dealing with other people's inquiries.

After all, Ning Chen couldn't say that he got these research results from the system.

Ning Chen has thoroughly researched these research results. As long as he asks academic questions about these research results, Ning Chen guarantees that he can answer them fluently.

After listening to Ning Chen's answer, although Yang Lianhua still found it a bit unbelievable, it was at least a tenable answer.

Some academic geniuses often seize the inspiration around them and use it as a breakthrough point for research problems.

Of course, inspiration is not the whole reason for solving problems, and a solid knowledge reserve is equally important.

Yang Lianhua was very satisfied with the answer he needed, but in order to further understand Ning Chen and ensure that all the research results were indeed from Ning Chen himself, Yang Lianhua still wanted to ask Ning Chen some more questions. "Ning Chen, why did you use the scattering inversion method when you were solving the exact solution of the Sine-Gordon equation?"

Ning Chen knew that Yang Lianhua was examining himself through these questions, and he didn't point it out face to face, so he replied calmly:

"When solving nonlinear partial differential equations, the methods we used before include function expansion method, homogeneous balance method, deformation mapping method, auxiliary equation method, mixed index method, etc. Scattering inversion method has been used to solve constant Coefficient partial differential equations, but I think that as long as some transformations and auxiliary calculations are performed, the scattering inversion method can also be used to solve nonlinear partial differential equations..."

While talking, Ning Chen took out the paper and pen, and started to deduce on the spot.

Compared with the previous process on the draft paper, Ning Chen's derivation this time was more detailed, which also allowed others to better understand his ideas.

"First perform Backlund transformation on the Sine-Gordon equation, then use the (G'/G) expansion method, and combine various symbolic calculations, we can find the exact solution of the variable coefficient Sine-Gordon equation..."

Looking at Ning Chen's derivation process, Yang Lianhua had to admit that Ning Chen really had a solid grasp of the entire solution process.

If he hadn't researched it himself, Ning Chen would definitely not be able to give such a complete answer.

After affirming Ning Chen in his heart, Yang Lianhua continued to ask:

"(G'/G) expansion method, can you explain it more carefully?"

"Of course. Let's make a transformation first, and substitute the formula into the Sine-Gordon equation. The left side of the equation is transformed into a polynomial of (G'/G), and the coefficients of each power term of (G'/G) is zero, the following equations are obtained..."

"Solving the above equations, you can get the solutions of a0(x, t), a1(x, t), α(t). Discussing the range of radicals, there will be three possible situations below..."

"Finally, by calculating these three situations separately, we can obtain the exact solutions of several sets of Sine-Gordon equations."

Ning Chen continued to answer Yang Lianhua's questions fluently, which made Yang Lianhua nod repeatedly.

He asked Ning Chen several related academic questions in a row, and Ning Chen answered all of them fluently, which made Yang Lianhua completely convinced by Ning Chen.

"Teacher Yang, apart from that, I think my research results still have certain practical significance."

"By inverting the scattering method to solve it, it is easier to find the connection between different solutions, which makes it much easier to solve the solution of the Sine-Gordon equation, and the solution process will be more concise."

"If you can further study the relevant properties, I think this method may be put into other nonlinear differential equations..."

At the end, Ning Chen didn't wait for Yang Lianhua to ask himself again, but rushed to answer directly.

Yang Lianhua also did not expect that Ning Chen had already thought of the significance of this research result and the subsequent research space. Such academic research capabilities are not possessed by many masters and doctors.

"Okay, I have nothing more to ask. Teacher He, you can prepare to guide Ning Chen to write a thesis."

Yang Lianhua must admit that what He Sheng said to him before was not bragging. It is true that students like Ning Chen have not been seen for many years.

Even Yang Lianhua himself, at the same age, couldn't compare with Ning Chen now.
