From black technology to super engineering

Chapter 10
Seeing the boy on the opposite side fell into silent thinking, Qi Yumo's eyes flashed a little pleasure.

This question is not a partial reciprocal in their advanced mathematics this semester, but a second-order partial differential equation (PDE), also known as a mathematical physics equation.

It is a compulsory course for sophomores in many science majors, or an elective for juniors in engineering.

Of course, lacquer and ink have not been learned yet.

No matter how studious you are, you have to have a degree, right?

So she just wanted to make things difficult for this boy - aren't you a good teacher?Then try the super-class problem.

……

As the boy's brows became more and more wrinkled, the lacquer and ink became more and more...

Happy!
But when she was happy, she was also a little worried...

Don't you go too far?

Then, she saw...

The boy pulled off his mask, rolled up his sleeves after drinking a saliva, and then wrote on the manuscript paper...

solution:
Let u(x,t)=X(x)T(t).

The ordinary differential equation that X(x), T(t) satisfies: X″(x)+λ2X(x)=0 T″(t)+a2λT(t)=0
Qi and Mo's eyes instantly widened!
?

……

Ye Ming quickly finished writing a piece of manuscript paper.

Immediately afterwards, he immediately pulled out his manuscript, but just as he was about to continue his analysis, he suddenly felt something wrong with the girl's eyes.

Looking up, I saw the girl's eyes were full of shock and disbelief.

This look made him wake up and alert immediately.

Did this girl come to test herself on purpose?
So he hesitated for a while, and wrote on the manuscript paper: "Although it takes time to analyze all the solutions, after finding the special solution, you need to expand the Fourier series, or... I will teach you the method?"

After finishing writing, he pushed the manuscript paper over.

The girl took the manuscript paper, and her gaze stayed on the manuscript paper for a full ten seconds before she exhaled slowly and wrote vigorously.

"Thank you, I'll take a look at the teaching materials and videos first."

"Oh, then we need to talk about it."

After finishing writing, Ye Ming saw that he could find the special solution in a few steps, so he simply turned over the manuscript paper, and directly found the special solution after omitting the analysis steps.

How should I put it, even if I guessed that the girl was testing me on purpose, but after doing the questions, there must be an answer.

After handing the manuscript paper to the girl, Ye Ming smiled at the girl and put on the mask again.

Today, the Heavenly King and Lao Tzu can't bother him to study!

Then...the phone buzzed.

The incoming call showed Peng Xiaofei's avatar, Ye Ming hung up the call unceremoniously and clicked into WeChat.

"Come to the Science and Technology Activity Center, let's fight."

Ye Ming was taken aback, and played one?Immediately click into the team group.

I saw Li Dongsheng @Everyone in the group, and asked all the students in the school to go to the fifth floor of the activity center. Not to mention that their site was robbed by the RM team, and the other side even made rude words and insulted the team.

Ye Ming frowned, and sighed after a few seconds of silence.

We are all civilized people... Fighting is definitely not enough.

But go, still have to go.

So he reluctantly closed the book and stood up again.

……

Although Qi and Mo took over the manuscript paper, their thoughts were not on the manuscript paper at all.

Her mind was full of Ye Ming's appearance when he was seriously doing the questions just now.

Is there really such an awesome person?

Is he really a freshman?

No... it should be a freshman...

Because he took off his mask when he was doing the question just now.

Judging from his appearance, he is not very old.

As for looks, let me ask...

Which girl would think that a boy who solves problems seriously is not handsome?

Just when Qi and Mo were feeling complicated, she saw that the boy seemed to be leaving.

Heartbeat speeded up at this moment.

She hesitated for a moment before deciding to follow her instinct.

She looked at the boy and said the first sentence in the exchange between the two.

"Can I add a WeChat?"

……

The Science and Technology Activity Center is not far from the library, and Ye Ming arrived before he had time to figure out how to greet this girl named "Feng Xi" on WeChat.

Well, in fact, the more reason is that that guy Peng Xiaofei has been harassing him and reporting the "battle situation" to him.

The current situation is that Li Dongsheng is arguing fiercely with a vice-captain on the opposite side.

Walking up to the fifth floor, Ye Ming heard Li Dongsheng's voice when he was still outside the door.

"Get out! It's not easy for anyone to come today!"

"Li Dongsheng, your team is about to disband, what are you going to do to my brother?"

"Cao Junwen is paralyzed!"

Then came the voices of persuasion from both sides...

"Hey, don't do it..."

Ye Ming pushed open the door.

I saw a group of people gathered in the middle of the wide field, and Li Dongsheng twisted into a ball with a boy opposite.

In the arena, several obstacles were built with various simple materials, and there were two mechanical tanks the size of basins parked in the arena.

There are also small acrylic balls the size of soybeans scattered around.

Ye Ming bent down to pick up a small ball and walked towards the crowd.

Then he saw that Peng Xiaofei hugged Li Dongsheng and said something in the other's ear, Li Dongsheng stopped struggling and looked towards him.

"Captain." Ye Ming approached, glanced at the opposite side first, and then asked softly: "Why did you fight?"

Li Dongsheng spat hard: "Team RM, the upstairs is their preparation room, but it didn't feel like it was enough, so they came to us and didn't say anything, and said we don't need it. Fuck!"

"You don't need it in the first place! The schools next door have already prepared for the competition. You haven't moved for a long time, and you have to change the plan. We will have a school team league at the end of March. What's wrong with using it first? Ah? What's the matter? ?” The man called Cao Junwen on the opposite side was not easy to provoke, and he sprayed back directly.

"Who said we didn't move? I'm going to use it soon."

"Pretend, you continue to pretend."

At this time, the door was pushed open again, and a serious voice sounded.

"What's the fuss!"

Everyone looked at the door at the same time, and then suddenly died down.

Because it was Professor Chen Xiaofang, the instructor of the RM team, and Mr. Zhang from the Youth League Committee.

One is the team leader.

One is the "golden master father" on both sides.

No one can afford it.

……

Five minutes later, the two teachers who had figured out the situation stood in the middle of the crowd, exchanged glances with each other, and Teacher Zhang from the Youth League Committee coughed lightly.

"In this way, although the venue on the fifth floor belongs to the RC team, the situation of the RM team is special now, and there are two competitions waiting for them. Upstairs they are preparing for the confrontation match, and the environment and venue required are very large, so there are not enough venues for the challenge match That's it... at the end of the month, we will have a 3V3 challenge for colleges and universities..."

Following Teacher Zhang's voice, the expression on Li Dongsheng's face instantly turned red.

Not only him, every member of the RC team had indignation written all over their faces.

what is this?Stretch?
Or, in the eyes of the school league committee, are my group of people abandoned?

"Li Dongsheng." Teacher Zhang is a female teacher. She felt Li Dongsheng's resentment and anger very sensitively. She frowned: "Don't be like this. Anyway, your competition is still early, and it will start in May."

"Mr. Zhang, we really need a venue for the competition! This year's rules are very complicated, and they are also very confrontational. We need to prepare early."

Facing the "gold master father" who gave the money, even though Li Dongsheng had ten thousand reluctances in his heart, he suppressed his anger and begged: "And we are very confident to win the prize this time!"

It's okay if he didn't say this, but when he said it, everyone's expressions on the opposite side became weird.

In the crowd, someone whispered, "If you don't have your head shaved, you'll be Ami Tofu."

Li Dongsheng's face flushed red again.

At this moment, a voice came calmly from outside the crowd.

"How about this, make an appointment, whoever loses will give up."

Li Dongsheng instantly looked towards the source of the voice.

Ye Ming just stood up from one of the tanks.

He also clapped his hands easily.
