As soon as Nuo Min heard Liu Chen's proposal, his head shook like a rattle, "No, no, your request is too much!"

"Don't you listen to the teacher again? Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo”

"If my mom finds out, she'll kill me. ”

"Then I'll go tell your mom now, you kid is disobedient, I can't teach it. ”

"You ......"

"Come on, if you don't say it, if I don't say it, no one will know, and your mother won't trespass. ”

"Is your body so weak, it's been more than an hour just now, and you still want to come?"

"How can it be enough for more than an hour, and when I come again, I am having fun, but I was interrupted by my aunt, it is too enjoyable. ”

……

Nuoda stood at the door and heard the conversation in the tent, gritted his teeth and retreated silently, and said in his heart, my sister is too wild, hey, the two of you are willing to do it, his brother is not easy to say, I wonder if my mother is still happy to see it.

As soon as he had finished a few words, there was a muffled grunt of men and women in the tent.

At dinner, Nuoda looked at Liu Chen and then at his sister, both of them ate easily, and the old lady still put vegetables in Liu Chen's bowl, and glared at her sister from time to time.

After the meal, the two hid in their bags again.

In the evening, Liu Chen fixed to tutor Nuo Min with homework.

Liu Chen went to the research group every morning to discuss the research progress of the previous day, solve the problems encountered, and then disappeared.

Seven days have passed.

Two of the groups had done their job, but they didn't see what happened to him, and Lezhnev waited and waited not to see the result, he didn't know what to do, but to see how the young man who talked big had ended.

The professors finished their work, and they were all waiting, discussing a few words with each other, and they couldn't help but worry in the casual conversation.

Huang Jie's expression was also a bitter gourd, he went to ask Liu Chen twice, this young man always waved his hand, not in a hurry, not in a hurry.

Can you not be in a hurry? The gatehouse has been burned.

The only person who is still calm is Zhang Zheng, who is responsible for the inverter under the guidance of Liu Chen, which has changed greatly from the past, but the result has not come out, and he doesn't know what will happen.

The tenth day arrived.

The inverter module, the main circuit series resonance module, the transformer, and the rectifier bridge module are assembled together, and the most critical controller module is missing.

Everyone came to the laboratory on the third basement floor, where dozens of engineers and technicians supported this important national project, and everything was ready.

Lezhnev circled around the equipment twice, raised his face, and said: "Ten days are up, I remember a guy who was ashamed to say that the whole equipment would be completed today." ”

The big guys were also excited, looking at Liu Chen suspiciously.

The ugly daughter-in-law always wants to see her in-laws.

Huang Jie looked at the young man, his face was still as usual, his breathing was smooth, he couldn't help but admire this psychological quality, his breathing began to be short, and he was about to start the net, is there a fish in the end?

Qin Ming also looked at Liu Chen, and in the discussions these days, he felt more and more that this young man was very accomplished, not like a person who was open-mouthed and grandiose.

Gong Shu smiled: "Little sir, are you ready? Let's reveal the mystery to us old guys." ”

Liu Chen took out the controller module that had been prepared a long time ago, and looked at it in surprise as Nev, this module had already been placed here, but he didn't pay attention to it at all.

The whole equipment is assembled.

"Chief Huang, send power, and the oscilloscope is connected to observe the boost waveform, and the overshoot and voltage accuracy can be known at a glance. ”

Everyone waited with bated breath.

Huang Jie's heart was beating fast, he controlled the switch, and pressed it tremblingly.

Everyone is looking at the oscilloscope screen.

Between the electric light and flint, a beautiful waveform appeared in the oscilloscope, the most important technical indicator is that there is no overshoot boost to 200kV within 1ms, amplification and amplification, and the static waveform locked in time within 10ms.

Really did it!

0。 The smooth curve rises to 200kV within 8ms, which is fully in line with the requirements, and there is no overshoot at all.

Oh my God, how is this done!

Hahaha, Huang Jie grinned, this is the most beautiful graphic he has ever seen in these days, it is simply more attractive than a peerless beauty standing in front of her completely stripped naked, and her thighs are twisted and looming for two days, this perfect curve seems to him to be the breast-room of a woman with the most beautiful curvature.

The two academicians and professors were a little tearful when they saw this waveform, and they did it, we all joined forces to do this, and some guys quietly took off their glasses and rubbed their eyes secretly, and the depression in their hearts was swept away, and the sunlight shone through the huge floor-to-ceiling windows.

How long has it been since I've been so happy?

When you are admitted to university, when a beautiful girl is willing to sublimate her revolutionary friendship, when she passes the defense of her graduate thesis, when she caresses her lover's body at night, or when she is promoted to a father, or is she rated as a professor?

It's been a long time, it's been a long time.

I have long been accustomed to fame and fortune and the respect of the people around me, and I haven't had the excitement of giving my all to accomplish one thing for too long, and I haven't challenged the limit for too long.

The old guys, with an average age of fifty-five, were once again excited, as if they had really experienced women for the first time.

Even Gong Shu and Qin Ming were flushed with excitement, especially Gong Shu's complexion was very white, as if he was drunk.

Qin Ming patted Liu Chen's shoulder sincerely, and said meaningfully: "Little sir, you are really a genius. ”

"Little sir, amazing. Gong Shu also said.

"Little sir, thanks to you, the country will not forget your contribution. Huang Jie smiled.

Listed as Nev is completely stupid, how is this possible, the resonant current zero-crossing switch switch, the control of the inverter is in a discrete state, how can it not be overshooted! It must be very overshooted, what the hell is going on? Playing magic?

He looked at the waveform little by little carefully with difficulty.

The whole device runs quietly, and the sound is very weak because it is a soft switch.

"What about the accuracy of the voltage after stabilization?"

His voice was not calm, and he asked abruptly.

Only then did everyone remember that there was an expert from Mao Xiong Country, and after this reminder, they all looked at it, Liu Chen adjusted the display of an oscilloscope, and said: "The output voltage changes within 200kV plus or minus 200V, and the accuracy is one thousandth." ”

"The technical specifications are five thousandths, which fully meets the requirements and the performance is very superior. Huang Jie couldn't keep his mouth shut.

How is it possible that Nev's mouth was wide open, and he looked like a living ghost.

Almost hysterically, he shouted, "What is the switching frequency?"

The series resonant main circuit is in charge of Professor Hua of Bingcheng University of Technology, snorted and said arrogantly: "98kHz." ”

Liu Chen explained with a smile: "This is to reduce the frequency for stability, and if it is a normal application, it is optimal to increase it to about 125kHz." ”

Lezuo Nev shook his head, this is absolutely impossible.
