"......" Qianqian nodded to Liu Chi, thanked him, and sat inside.

"Thank you!" Ying Ying glanced at Liu Chi a little curiously, always feeling as if she had seen it somewhere, but she couldn't remember it for a while.

Forget it, it's the public eye anyway, everyone is familiar with it!

"It's fine. ”

“......”

In less than 1 minute, the waiter went and returned.

"Sir, this is the pen and paper you want, do you see enough paper? Not enough, I'll get it for you later." The waiter gently placed the pen and paper on the corner of the table.

"That should be enough, thank you. Liu Chi took the pen and paper and picked it up.

“.......”

"Can you two order food?" After the waiter confirmed that Liu Chi was fine, he targeted the two beauties opposite Liu Chi.

Liu Chi got the paper, and if there was no one else, he brushed and wrote on the paper.

F=mv2/r=mrw2 v=rw

T=2π/w=1/f

......

WAB=qUAB（E=qU）///UAB=φA-φB

......

s=v0t+at2/2

vt=v0+at

vt2-v02=2as

......

I=E/(R+r)//

......

i=e/（R+r）= (NBSw/(R+r))sin(wt+φ) =Im sin(wt+φ)

Liu Chi wrote while flipping through his mobile phone, and his serious energy attracted the attention of the two beauties who had already finished ordering, Qianqian curiously turned her head closer to Yingying, and whispered: "Do you understand?"

"Seems to be a formula for electromagnetic fields?" Ying Ying also responded in a low voice.

"So diligent, isn't it cold to wear so little?" Qianqian secretly glanced at Liu Chi, and said darkly: "You won't pretend to show us, right?"

"......" Yingying turned her eyes at Qianqian's divine circuit.

"Sir, your dish is here. ”

"Put it first. Liu Chi didn't raise his head and continued to struggle on the paper, and the formulas kept jumping onto the paper.

Because of the hardware, since I can't directly turn thermal energy into electrical energy, I will directly use two positive and negative formations to create a small magnetic field.

Although because of hardware problems, it is not possible to install a 'big fan' for cutting.

But what if I fix the coil and the magnetic field moves or changes?

This is not...

I'm a genius!

Electromagnetic induction!!!

This method should be reliable.

It's very feasible, and if it does, it's all solved!

The amount of current used to start the board is not very large.

A small magnetic field should solve the problem.

Now it's about how to generate the magnetic field.

Or strengthen the Earth's magnetic field within a certain range.

As for which method to use, you have to try it slowly.

By the time Liu Chi had roughly sorted out the materials, it was already half an hour later, and he carefully folded the paper and put it away, only to find out that he had forgotten to eat.

Qianqian Yuguang saw Liu Chi treat the two pieces of paper full of formulas as if they were treasures, and pouted, not knowing whether he was really diligent or pretended.

Liu Chi looked at the already cold dishes, and couldn't help but want to smoke himself with a big mouth, and forgot about the business as soon as he was inspired.

The temperature in the store seems to be quite high, not as cold as outside, Liu Chi didn't pick it, picked up the bowl and chopsticks, and began to sweep.

In less than five minutes, Liu Chi put down the bowl, stood up and nodded to the two beauties, and then paid the bill and left!

......

"I'll go, what's the situation?" Qianqian looked at Liu Chi, who had already left, with a confused expression: "This person won't have a problem, right?"

"I don't know. Ying Ying didn't react for a while.

It's weird!

"Seeing him so attentive just now, I was embarrassed to speak. Qianqian was a little apprehensive, pouting, where she was not in the C position, but now she has become a passerby.

Uncle is bearable, aunt is unbearable!

"What's the matter, our Qianqian beauties are moving?" Ying Ying quipped: "Or people haven't asked you for a phone call, and your sense of existence hasn't been brushed?"

"Do you want me to get a phone for you?"

"I listen to what you say, why do you feel so awkward?" Qianqian's eyes squinted, and she said with disdain: "A straight man like this, the disgust that I gave away for nothing, looks like a science dog." ”

"Hey, huh?"

"You see, when we first came to the audience, we took a look, and then when we left, we glanced again, and we didn't say a word. Qianqian grumbled.

"Haven't you seen that this handsome guy suddenly came to inspiration?"

"I don't know which school it's a student. After Qianqian finished speaking, she put down the chopsticks in her hand: "I'm full." ”

"I'm almost there, the food in this store is okay!"

"It's great, I'll come to Yanjing for another meal. Qianqian nodded in approval and gave a thumbs up.

"Okay, it's time for you to invite me. ”

"No problem. Qianqian picked up her small bag and stood up: "I'll invite you then." ”

"Wait!" Ying Ying was stunned.

"What's wrong?" Qianqian took a moment to react, tilting her head to look at Ying Ying.

"I remember who that person was. ”

"Huh?"

"He's a friend of mine, and I've met him once, and I said it's a little familiar. Ying Ying slapped her head and summoned the Tao of enlightenment.

"Really?"

"Well, you invited me to dinner two years ago, but because it's been too long, I didn't remember it all at once. ”

"Everybody's gone. ”

"Forget it, let's go!"

"Let's go!"

“......”

When Liu Chi came to the parking lot downstairs, he shivered when the cold wind blew, and ran into the car three times and twice: "Chen Fei, go back to the company." ”

"Ah, isn't the boss going home?" Chen Fei was stunned, it was already more than a little now.

"Go back to the company first, don't go home at night, wait for me to send me back to the company, and you will go back to rest." Liu Chi looked out the car window: "Why is it so cold today?"

Chen Fei said while driving, "Boss, the cold air is going south, it is estimated that it will be cold for about a week, pay attention to keeping warm." ”

"No wonder, it's okay, I have clothes in the office, let's go. ”

“......”

After Liu Chi returned to the company, he put on a coat in the office and plunged into the laboratory to deduce the feasibility of magnetic field power generation.

Next.

When Ye Yuxin came to the company, she saw the four circles of the parking lot, and rubbed her eyes incredulously, what is the situation?

Is the sun coming out of the west?

I didn't reply to my message until 12 o'clock last night.

I guess I won't go to bed until one or two o'clock.

I went to work earlier than I got to work today.

？？？

"Brother Fei, it's so early today. Ye Yuxin saw Chen Fei basking in the sun and said curiously.

"Well, Manager Ye is early. ”

"What time did Liu Chi come, why is it so early today?" Ye Yuxin asked curiously.

"The owner didn't go back last night. ”

“？？？”

“......”

If you don't go back, it's all night tomorrow night? Don't die? Ye Yuxin couldn't help but burst into a small fire in her heart, seeing that I wouldn't clean him up, and said to Chen Fei: "I'm going to work."

Ye Yuxin's steps were faster than usual.

When I came to Liu Chi's office, I saw the guy rolling on the sofa like a loach, and his coat was still on his stomach.

It seems to be asleep.

Ye Yuxin, who originally wanted to knock on the door, stopped her raised hand, forget it, buy this guy breakfast first and come back, and then clean him up later.

It was nearly ten o'clock when Liu Chi woke up and looked at the breakfast box on the table.

After glancing at the time, the corners of her mouth couldn't help but squeeze a wry smile, and it was estimated that the girl would have been nagging for a long time.

I washed my face and came back, and I wiped out the breakfast by dividing it by two.

Turn on the computer, yesterday the derivation of the generated magnetic field has been completed, and today's task is to perform the calculation.

At lunchtime, Ye Yuxin appeared in Liu Chi's office on time.

A meal of complaining is naturally indispensable.

......

Half a month later.

"Director Zhang, good morning. Liu Chi called Zhang Lin of Research Institute A.
