I just want to be a quiet scholar

Chapter 58 How to explain this

"6 meters, I won." Shen Qi stood up from the bunker and patted the sand.

"I'm so shocked, Shen Qi." Xu Rui was puzzled, "This kind of long jump with a run-up is not a standing long jump. It is difficult for ordinary high school students who have not received professional track and field training to jump above 6 meters, unless they are born to bounce. Amazing power. And you are obviously neither the latter nor the former."

Shen Qi said, "In recent months, I have been practicing running every day."

"You practice aerobic low-speed running, does it have anything to do with the long jump?"

"Is it okay?"

"Have it?"

"do not have it?"

"Don't talk about it, I admit the bet and give in, and invite you to eat chicken chops at night. My mother died of poverty recently, but don't worry, no matter how poor I am, I will not break my promise." Xu Rui sat on the ground beside the bunker and pulled out his sports bag. The zipper took out two bottles of Pocari, handed one to Shen Qi, and kept one for himself.

"The track and field team eats, drinks, and distributes nutritional supplements. Where did all your money go?" Shen Qi took the drink, twisted the cap, and took a few gulps.

"Hey hey, I met a girl recently. She's super pretty. Of course it costs money to pick up a girl." Xu Rui smiled happily, took out his mobile phone from his sports bag, and opened a photo for Shen Qi to observe. It is Chi Guoguo's dog abuse that proves that he is out of the single.

Shen Qi admired the girl's photo with great interest, and then spit out a drink with a "poof".

"So what if you study well, you're not still a single dog, hahaha." Xu Rui couldn't stop laughing, very embarrassed.

"Cough cough." Shen Qi choked on the water and coughed several times.

"Are you surprised by my sister, single dog?" Xu Rui swiped the screen of his phone, "Look, there, this, this, and this."

Shen Qi couldn't help it anymore: "Is this your girl in the picture?"

"Yes."

"She must be 180 pounds, right? Super pretty?"

Xu Rui asked back: "What's wrong with 180 pounds? She is a student from the province, and she specializes in shot put. We met at the U19 Games in the province."

"Xu Rui, is there something wrong with your aesthetics?" Shen Qi was incomprehensible.

"You have a problem with your aesthetics!" Xu Rui was unhappy, and added: "I'm serious, Shen Qi, I believe in love again. I'll show you the picture when you're a brother, don't make me mad ."

"Okay, good, I wish you happiness, the sea is dry and the stone is rotten and the white head is not separated. Hey, Xu Rui, do your parents know that you are picking up a girl?"

"Let's hide it for now and tell them after I go to college. So I have to win the national U19 [-]m champion and go to Shuimu University. As long as I am sent to Shuimu, hehe, I can do whatever I want, just like you, Shen Qi. "

"A girl changes a man's life." Shen Qi sighed that he was only over 130 pounds, so it was difficult for him to accept a girlfriend who weighed 180 pounds.

The two chatted for a while, seeing that it was almost two o'clock, Shen Qi walked towards the teaching building, Xu Rui stayed on the playground and worked hard to train for his dream of Shuimu University and his shot put girl.

Just walking downstairs, Shen Qi's cell phone vibrated, he took out his cell phone and took a look, hey, the editor sent a message on the button.

More than a week ago, Shen Qi submitted a mathematical paper to the editorial department of the "Mathematics Innovation News", leaving his mobile phone number and Kuku number.

The next day, Jia Shen Qi, an editor of "Mathematics Innovation News", was a friend of Kou Kou and said to keep in touch.

Then a week passed without any contact.

Shen Qi even thought to his dismay that his debut thesis had been knocked off, and he was about to write a new thesis.

Fortunately, the editor sent an exciting news at this time: "Shen Qi, after the initial review, the paper you submitted to our journal "Some solutions to linear inhomogeneous differential equations with constant coefficients of the second order" meets the requirements of our journal for acceptance. , I would like to discuss with you in depth about some details of the paper. I hope to reply. "

Shen Qi immediately replied: "Okay."

Edited greatly: "On page 7 of your paper, let y=vx, and substitute it into the equation to separate the variables, and get the solution of the separation of variables and the homogeneous equation."

"I disagree with the variable separation method of ordinary differential equations that you use. You can solve high-level problems with this method, but if you write a thesis, it is obviously not rigorous enough."

"Also, on page 12, I think you misunderstood the Riccati equation, I don't understand how you transformed z=v+u^-1 to be linear?"

"Of course, the flaws do not hide the flaws. Except for the above-mentioned minor flaws, the overall conception and presentation of your paper basically meet the requirements for publication."

"To chat with you today, I hope you can correct me. Shen Qi, what do you think?"

What do I think?I have too many opinions, which cannot be explained to you in one or two sentences.

Shen Qi replied: "Please wait a moment, I will ask the school leaders for instructions, and I will give you an answer later."

There are still a few minutes left for class, and the first class in the afternoon is mathematics.

Shen Qi greeted Zhang Wanbang and said that he wanted to go to the school library to check materials.

Zhang Wanbang waved his hand, go, do what you like, don't ask me.

Shen Qi came to the library, where there was only one administrator looking after the door.

There is no need to check the materials. Shen Qi can't use the materials in the school library at all. He took out his mobile phone and discussed with the editor: "Sorry for keeping you waiting. I'll start with page 7. I introduced new variables t and v. , so that equation (8) can be regarded as the parametric equation of x and y with respect to v, and then I calculate dy/dx and d^2y/dx^2 logically..."

"Please turn to page 11 of my paper. After I substitute equation (15), I get a second-order equation of t as a function of v. It may be a bit jumpy here, but it is closely related. I hope you Can see..."

"The discussion on page 12 and the conclusion on page 14 are also related. I fixed the undetermined constant α, thereby eliminating the exponential factor, so that v no longer appears obviously, and then transforming z = dv/dt, I will make the second-order equation For the first order, deduce a general solution formula... Can you understand if I explain it this way?"

The editor at Koukou was silent for 10 minutes.

Shen Qi was a little anxious: "Are you still online?"

The editor finally replied, and instead of discussing academic issues this time, he asked: "Shen Qi, which institution are you from? You didn't leave your institution or research institution in the thesis materials."

Shen Qi: "Local."

"Mathematics Innovation News" is a professional publication sponsored by the School of Mathematics, CUHK, a local 985 University. Although it cannot compete with "Mathematics Herald", the most authoritative and oldest mathematics publication in China, the young "Mathematics Innovation News" also It is one of the thriving professional mathematics journals in China.

The editor of "Mathematics Innovation News" learned that Shen Qi was local, and asked, "Which local college? Are we at CUHK or Huagong, Jinda, Huanong, and Huashi?" The editor hit all local colleges and universities in 985 and 211 in one go came out.

Shen Qi: "I'm from high school."

Editor: "Mr. Shen, which local high school do you teach at?"

Damn, the editor thinks I'm a high school math teacher?Shen Qi couldn't help laughing. Some high school math teachers wrote papers and submitted them to professional journals in order to evaluate their professional titles.

But I am not a teacher!
Shen Qixin said, how should I explain this to the editor?
