Cao Zhenggang smiled and said, "Xia Lu, you got full marks in all your courses last semester, ranking first among your students. You are excellent and hope to continue to study well. ”

Yu Feng also praised Xia Lu: "Make persistent efforts to surpass yesterday's self." ”

The two professors gave 100% recognition to Xia Lu's excellent success in the regular courses.

Xia Lu said that he wrote some experiences about nonlinear partial differential equations, and the two professors automatically filtered them without asking too much.

"Two teachers, I'm here, why don't you take a look at what I wrote?" Xia Lu patted the file bag and put it on Cao Zhenggang's desktop.

"Xia Lu, I can understand your desire to improve, but don't be in a hurry. I still say the same thing, first lay a solid foundation, and then participate in some advanced projects, and the future will be long. Cao Zhenggang didn't open the file bag for the first time, he was very busy, he said to Xia Lu: "Xia Lu, you go back first, I will read what you wrote when I have time." ”

"Well, okay, don't bother the two teachers, I'll go first. Xia Lu then left, and gently closed the door of the office after going out.

"Xia Lu is still a very good student and self-motivated. Yu Feng has always been very optimistic about Xia Lu, and he said: "When Xia Lu is a sophomore, he can be allowed to participate in some basic projects, he is worth cultivating." ”

"I think it's okay. Cao Zhenggang nodded, then looked at the blackboard, his face became more and more solemn: "Yu Feng, it is our responsibility to train undergraduates, and the same is true for scientific research. Let's hurry up and study this topic, we really don't have much time left. ”

"Headache...... Yu Feng rubbed his temples, he patted the document bag brought by Xia Lu, and said, "Xia Lu, this kid, really went to study our subject?"

Cao Zhenggang: "I appreciate Xia Lu's attitude, and after completing this project, I will spend more time guiding Xia Lu." ”

"Lao Cao, aren't you a little interested in reading what Xia Lu wrote?"

"How can I have the time and mood now to review the experience of a freshman student's writing? It is true that Xia Lu is the best of the freshmen, but even the best freshmen cannot touch the true meaning of such advanced mathematical and physical knowledge. ”

"Anyway, I don't have a clue now, you don't look at it, I'll see it. Yu Feng opened Xia Lu's file bag and took out a stack of A4 paper bound together, with more than thirty pages, printed on the front and back.

Yu Feng glanced at the title of the homepage, and he thought it was a little interesting: "A method for solving the optimal system, exact solution and conservation law of nonlinear partial differential equations that is both universal and applicable to specific application environments...... Xia Lu, this guy, play really?"

Flip File, Page 2, Page 3......

Yu Feng thought it was a little interesting at first, but when he looked at it, he found it quite interesting.

Page 15, page 16......

Yu Feng stopped talking, his face was full of incredulity.

On page 29 and page 30, Xia Lu gives the results of the calculation on this page.

Yu Feng stared at the symbols on the paper, and his heart was filled with great shock.

The last page, page 32, is summarized by Xia Lu, who thinks that he has given a reasonable new method that can be applied to the specific application environment mentioned by Professors Cao and Yu.

Yu Feng's expression changed so wonderfully, Cao Zhenggang saw it all.

It was clear that there was something about the document that Xia Lu had brought with him, so much so that Cao Zhenggang's academic partners were frightened.

"Yu Feng, what's the situation?" Cao Zhenggang guessed that there must be a situation.

"Lao Cao, see for yourself. Yu Feng handed the document to Cao Zhenggang, he took a deep breath, and his mood was very complicated.

After reading Xia Lu's documents, Cao Zhenggang was also frightened.

"This ......" Cao Zhenggang didn't know what words to use to describe his mental activities at the moment.

"Xia Lu is not an ordinary person. Yu Feng frowned, and he said, "I want to know, who is the master behind Xia Lu?"

According to the paper...... Let's take it as the prototype of a paper draft, judging from the technical techniques of this paper, could it be that the master behind Xia Lu is Xia Boliang?" Cao Zhenggang was nervous, and the person he didn't want to mention the most was Xia Boliang.

Xia Boliang is a professor of mathematical physics at Tongji University and a well-known young scholar in the industry.

Originally, two research teams were interested in this partial differential equation project, one was Cao Yu's group from Jiangcheng University and the other was Xia Boliang's team from Tongji University.

The state suggested that Cao Yu's team work with Xia Boliang's team to complete the project, but both sides refused.

The official statement of the two sides is that there is a difference between the scientific research system and academic thinking of Jiangcheng University and Tongji University.

After some consideration, the state finally decided to let the Cao Yu group of Jiangcheng University undertake this scientific research task.

"Xia Boliang's technique is similar, but it is not like it at all. Yu Feng was unable to make a judgment for a while, he said: "Xia Lu, Xia Boliang, they won't be relatives, right?"

"If there is a relationship between Xia Lu and Xia Boliang or other peers, this matter will be very complicated. Cao Zhenggang fell into deep thought.

The two professors' minds had gone beyond the purely academic realm, because the document in front of them was so strange.

From the academic aspect, the paper brought by Xia Lu preliminarily answered the academic doubts that plagued Cao and Yu for a year.

Otherwise, it would have been impossible for Xia Lu to complete this thesis alone.

Is it possible that the two professors Cao and Yu spent a year unable to solve the project, Xia Lu solved it in more than two months?

When pigs fly.

Then, there must be a master behind Xia Lu, or an elite team.

"I think it's time to talk to Xia Lu. Cao Zhenggang picked up his mobile phone and prepared to call Xia Lu.

After thinking about it, Cao Zhenggang put down his mobile phone and did not dial the number.

It was more than ten o'clock in the morning when Xia Lu delivered the documents, and it was already more than nine o'clock in the evening.

Unconsciously, Cao and Yu studied this document for a whole day.

"It's so late, let Xia Lu rest, arresting people at night has a feeling of interrogation overnight, it's not appropriate. Cao Zhenggang said.

"Okay, tomorrow morning, let's talk to Xia Lu. Yu Feng nodded and said, "Regarding this paper, I still want to ponder again, no matter whose work it is, it is undeniable that it is a near-perfect work." ”

Therefore, Cao and Yu studied Xia Lu's "A Method for Solving the Optimal System, Exact Solution and Conservation Law of Nonlinear Partial Differential Equations with Universal Significance and Applicable to Specific Application Environments" overnight......

At this time, Xia Lu was checking materials in the library, and he waited for a call or text message from Cao and Yu for a day.

However, until the turn of the clock, Xia Lu did not wait for the call of the two teachers.

"Could it be that the method I wrote has no value in the eyes of the two teachers?" Xia Lu was a little apprehensive, he felt that he couldn't, this method was theoretically impeccable.

There is also a possibility that the two teachers studied all day and they didn't understand my writing method?

Xia Lu is so tangled.

Forget it, let's go back to the dormitory and sleep first.

At 7 o'clock in the morning, Xia Lu received a WeChat message from Cao Zhenggang: "Xia Lu, you don't have class this morning, come to my office to sit down." ”
