Hao Tian nodded and said, "Yes, yes, his company's company is Runhua Supermarket...... The one directly opposite. ”

My mother was surprised, and she asked, "What kind of supermarket is that across from the RT-Mart supermarket?"

Hao Tian said: "Honghua...... Convenience stores. ”

The mother was stunned, and then moved the corners of her mouth, as if she was smiling or not smiling, I don't know whether she was happy or angry.

It should be unhappy.

Mom has a kind of fooled rush.

"Tiantian, you are still very young, you will meet better boys in the future...... Wait, the Honghua convenience store on this street seems to be opened by your high school classmates, right?" Mom shook her body, as if she remembered an important piece of information.

"Yes, that convenience store is opened by Xia Lu's family, and I'm ...... Socialize with Xia Lu. The truth was finally revealed, and Hao Tian said her boyfriend's name.

"Xia Lu, it's actually him. "Mom was really surprised. Xia Lu is still very famous in Jiangcheng No. 2 Middle School, after all, he was the student with the highest score in the college entrance examination last year.

"Well, Xia Lu is very powerful, he is studying in the science experimental class of Hongyi School of Jiangcheng University. Hao Tian knows her mother's personality very well, her mother cares a little about material things, and her mother also appreciates talented people.

Hao Tian's father was a poor boy back then, but his father was very eager to read, his father graduated from Shanghai Jiaotong University with a major in civil engineering, and entered the infrastructure enterprise after graduation, and was an excellent engineering man.

The mother with better family conditions fell in love with her father at first sight, and the two became husband and wife under the arrangement of the party, and their married life was very happy, especially after Hao Tian.

"Xia Lu, this student is very good at reading, but is there something wrong with his brain?"

"Huh?"

"With more than 700 points in the college entrance examination, Qingbei came to dig him up, and he chose his major, but he didn't go to Qingbei, do you think he has a brain in water?"

"Everyone has their own ambitions. ”

"Xia Lu has the strength of a bird, but he only has the ambition of a bird, it's a pity, it's a pity. The mother shook her head and sighed, she instructed her daughter: "Tiantian, you can have a relationship with Xia Lu, but I still say the same thing, you are very young now, and you will meet other excellent boys in the future, don't hang yourself on a tree, understand?"

"Hehehehe...... I'm going grocery shopping, and my dad will come home tomorrow, and our family of three can finally be reunited. ”

With the arrival of the Spring Festival, each family has its own affairs, and the frequency of Xia Lu and Hao Tian meeting has decreased.

After the fifteenth day of the first lunar month, the universities opened one after another, Xia Lu returned to Jiangcheng University, and the new semester began.

His mental strength and physical functions have all become stronger, and Xia Lu is full of ambition to do something.

In the library, Xia Lu immersed himself in the study of "a method for solving the optimal system, exact solution and conservation law of nonlinear partial differential equations that are both universal and applicable to specific application environments".

The Elite Two-Star Brain Value is quite effective, and the mathematical and physical theory system that Xia Lu was originally difficult to understand is being rapidly understood and absorbed by him.

"So, I can find the optimal system of one-dimensional subalgebra......"

Xia Lu performs the calculus on scratch paper, aV1+bV2, when a∈{-1.0,1}, b∈R...... The fifth-order nonlinear wave square is symmetrically reduced, so that the ...... can be obtained

The [method] that I spent 200 points to buy in the system is actually an answer.

To give this answer, at least the brain power of the hegemon.

Fully understand this [method], with Xia Lu's elite two-star brain power, it is basically enough.

What Xia Lu is doing now is to thoroughly understand the [method].

To this end, Xia Lu studied a large number of professional literature in the field of mathematics and physics, from "Partial Differential Equations" to "Separated Variables", from PRL to AnalMath.

Spring is the season of mating.

Creatures that have mating objects are busy mating.

Creatures that don't have mating partners are busy looking for mating mates.

For Xia Lu, who spends his days in the library, he seems to have found something more interesting than mating.

"I understand this method, I understand it thoroughly!" Xia Lu rubbed his hands excitedly, in this spring, he reaped the results.

Create a new LaTex document on his laptop, and Xia Lu will enter the [method] he understands into the document.

……

In Professor Cao Zhenggang's office, he stared at the blackboard, his brows furrowed.

Professor Yu Feng also had a similar expression, his face was solemn, and he looked very stressed.

"In another month, we will report to the school on the progress of this project, and I am a little panicked. Yu Feng clenched his fists and crackled his knuckles.

"It's a fart. Cao Zhenggang knocked on the blackboard and said, "Thinking about how to solve this problem is the only way out for the two of us." ”

"Lao Cao, why don't you make a report to the above and delay the delivery deadline of this project for half a year. Yu Feng said tentatively.

"It's not possible. Cao Zhenggang shook his head resolutely and said, "The date of the above report is fixed, and when the deadline is reached, we must hand over qualified research results." There is no turning back from the bow, we can only succeed and not fail. Yu Feng: You must realize the seriousness of the situation, if you can't complete the task on time, at worst, our academic level is limited, and it is an academic dereliction of duty. At worst, it is a moral problem for us to arbitrage scientific research funds, and only take money but do not contribute. ”

"It's not that we don't work hard, but the subject is getting more and more complex, and it has surpassed our previous assumptions. Yu Feng walked to the blackboard and said, "We have made a local symmetry of the fifth-order nonlinear wave equation, but it is just another expression of the KK equation. In other words, the application problems that cannot be solved by the KK equation, the CK direct method, and the Bucklen transform method are also powerless. Lao Cao, I'm embarrassed to mention any Cao-Yu method, we were too inflated before, and at present, it seems that Cao Zhenggang and Yu Feng are two wastes, and it is impossible for the academic community to fate a new method in the name of two wastes. ”

Ay......

Cao Zhenggang sighed, looking so depressed and irritable.

Knock knock.

That's when there was a knock on the office door.

Cao Zhenggang said weakly in the direction of the gate: "Come in." ”

The door opened, and a person came in, it was Xia Lu.

"Xia Lu, do you have something to look for me?" Cao Zhenggang straightened his collar to make himself look majestic and majestic in front of the students.

No matter how difficult it is, a professor should not show a depressed appearance in front of his students.

"Yo, Teacher Yu is also here, that's great. Xia Lu held a bag in his hand, he looked at the blackboard, and said: "Before the Spring Festival, I was very honored to listen to the academic discussion of Mr. Cao and Mr. Yu on the topic of nonlinear partial differential equations. Taking advantage of this winter vacation, I studied this topic specifically and gained some insights. I've written something about nonlinear partial differential equations, and I'd like to ask two teachers to review them. ”
