"If the three of us plus Zhou Meng and Liu Chi fight, the outcome will be 50-50."
"..." Liu Bing said nothing and waited for Li Haiqing to write more.
"Do you know what Liu Chi taught Zhou Meng? sis algorithm, force field suspension magnetism, ipe node system science, Mouse ring fission, these are the most cutting-edge fields of computer and artificial intelligence. Liu Chi can teach them all."
"It can be said that I have taught you all the skills of pressing the bottom box."
"So powerful? Isn't that more powerful than Liu Chi?" Liu Bing glanced at Li Haiqing suspiciously.
"That's why she is so powerful. I have never won against her." Li Haiqing smiled bitterly and said: "Liu Chi was taught by a monster, how can she not be great? She is great at computers, while Liu Chi is
All areas.”
"Really or not, so fierce?" Liu Bing originally majored in computer science and was very clear about Li Haiqing's position. Now he was a little surprised to hear Li Haiqing say that he had never won.
"..." Li Haiqing nodded.
"Okay, your circle is full of top students." Liu Bing said curiously: "Then why does she suddenly want to return to China?"
"I don't have a problem with this. I guess I'll come back and play."
"Then she should call Liu Chi. Why did she call you?"
"How do I know? This girl has been very strange since she was a child. The three of us have often tricked her, and we are too young to let her go." Li Haiqing said helplessly.
"..."
Jiang Yu was very fast and got the materials back in three days. Liu Chi took a lot of materials and rushed into the laboratory.
Test materials, etching array.
Just when Liu Chi was concentrating on doing experiments;
"Ring, bell, bell..."
"..." After the phone rang for more than a dozen times, Liu Chi picked up the phone, looked at the call, and was stunned for a while before pressing the answer button: "Hello!?"
"Guess who I am?" A smiling and delicate voice came into Liu Chi's ears.
"Kitten?" Liu Chi sat down on the chair, leaned back, assumed a comfortable posture, raised the corners of his mouth, and cooperated.
"wrong!"
"puppy?"
"Humph! Brother Chi is the bad guy, and you are the kitten and puppy."
"Okay, you girl, don't you think I can't deal with you because of the distance, right? You dare to attack me, I think you are going to shake things up." Liu Chi rolled his eyes and threatened.
"I'm not afraid. Haven't you heard a saying: The sky is high and the emperor is far away." A sound of laughter as clear as silver bells passed into Liu Chi's ears.
"What? My 'Boss Zhou' is out of prison?" Liu Chi changed the subject, otherwise he could keep talking to this girl until tomorrow without even breathing.
"Well, I'm out of quarantine." After Zhou Meng finished speaking, he added: "I also handed in my graduation thesis."
"So fast?" Liu Chi was really surprised this time: "Really or not? Didn't you girl fool me with the movie?"
"Of course it's true. Once the thesis is passed, I can get my diploma. It will only take two or three days." Zhou Meng said proudly: "You taught me how to do it."
"Isn't it normal to be outstanding? Otherwise, why would I be your student?"
"I like to hear this."
"Hey hey hey!"
"It's midnight over there right now, don't you need to sleep?" Liu Chi asked after looking at the time.
"Well, in the middle of the night, I'll go to bed soon."
"Girls should go to bed early, otherwise they will age quickly."
"No way, I am a young and beautiful girl." Zhou Meng said with a smile: "By the way, I will return to China in a few days, and you will treat me to a big dinner then. By the way, you are a big boss now.
With."
"It's just a waste of time and money," Liu Chi said with a humble face.
"Humph, the food, accommodation and food are all yours anyway."
"Okay, are you coming back for a few days or are you staying for a long time?"
"After graduation... of course I will go back to grow up." Zhou Meng said matter-of-factly.
"No problem, I have an empty room at home and I'll leave one for you."
"I want to stay in a five-star hotel." Zhou Meng said naughtily.
"..." Liu Chi ignored it and forcibly changed the subject: "You are back, what will your parents do? Do they support it?"
"I don't know. I haven't told them yet. I want to wait until I get my diploma before I tell them." Zhou Meng added after saying: "Anyway, regardless of whether you support me or not, I must go back."
"Communicate well and don't lose your temper, or I'll beat you up." Liu Chi pretended to be your teacher.
"I know." Zhou Meng said, "I am a good boy."
"Call me when you've decided."
"Um!"
"..."
One week later.
Liu Chi grinned, rubbed his hands, and looked at the newly assembled motor in front of him with a smile.
Done!
Now it's time to test the machine.
After Liu Chi checked and confirmed that there was no problem, he carefully connected the electricity, checked again, confirmed that there was no problem, and pressed the switch.
With a sound of "Weng...", the motor rang.
The spindle instantly rotated at high speed.
Ten minutes passed.
Works fine.
Nothing wrong;
Liu Chi looked at the motor that was still working hard and breathed a sigh of relief.
Then various tests will be conducted later.
Rotation speed, vibration, centrifugal force inertia...the most important ones are the dynamic balance and static balance of the rotor.
Turn off the motor.
Test the vibration first:
First install the corresponding instruments.
Secure one side of the motor.
Define 0 degrees.
Power on...
After Liu Chi pressed the switch, he turned his attention to the display of the balance meter next to him.
0.5 grams!
Well......
Liu Chi scratched his head, it seemed like it was a bit far off.
If you want to reach 1um, then the spindle is only allowed to have a maximum of 0.2 grams of unbalanced residual amount. Liu Chi looked at the motor that was still working for a while, and then glanced at the value that was motionless like an old stubborn.
It seems to be caused by the unbalanced centrifugal force of the rotating body.
I don't know if it's a magnetic field problem or an unbalanced mass of the rotor. We'll have to test it slowly to find out.
It doesn't matter, it just needs to be done in the right way, and then it can be improved slowly.
If you want to get it right at once, it basically doesn't exist.
If the pressure generated by the bearings is the same, then the problem will occur in the rotary body that is originally balanced. However, when the rotary body rotates at high speed, the centrifugal force should be uniform...
Liu Chi touched his chin for a while:
Is it a material problem? Causes uneven stress?
The material is uneven, or there are errors in the blank, processing and assembly, so that when the rotary body rotates, the centrifugal inertial force generated by each tiny particle on it cannot cancel each other out.
That will produce obvious errors.
It may even cause vibration, generate noise, accelerate bearing wear, and shorten the mechanical life.
...
Five minutes later, Liu Chi turned off the switch of the motor. After the motor stopped working, he disassembled the motor and took out the rotor.
Since it can work normally, let's test it one by one.
Find the problem and slowly correct it.
There's no rush anyway.
Rotor balance:
Liu Chi opened the balancer se008, put the rotor on it, and started...
0.95 error!
It was 0.5 grams just now!
If the error is 0.95, it should be 0.3 grams! That means the force field in the stator is uneven, adding a residual force of 0.2 grams to the rotor.
...
At around five o'clock in the afternoon, Ye Yuxin saw Liu Chi stop what he was doing and interrupted hurriedly: "Idiot, it's time to eat."
"Eat." Liu Chi replied and looked at the time.
I'm going!
In the blink of an eye, half a day passed.
It seems like he doesn't have much work to do.
well!!!
This time is so useless, it passed in the blink of an eye.
"It's almost six o'clock. It's okay. We'll continue tomorrow."
"Okay." Liu Chi glanced at the pile of equipment on the workbench. It seemed that he wouldn't be able to handle it for a while. Let's continue tomorrow and simply organize the equipment.
Pack up, pack up, archive, archive.
Turn off the instrument.
Follow Ye Yuxin out of the laboratory.
go home!
"parking!!!"
Just after leaving the industrial park and passing through a trail, Liu Chi suddenly spoke.
‘Squeak…’ The car stopped steadily.
"What's wrong with Liu Chi?" Ye Yuxin was shocked.
"It's okay." Liu Chi waved his hand and looked at the beautiful figure outside the window, his eyes twitching involuntarily.
Zhou Meng looked at the lowered glass window, walked a few steps forward, walked to the car door, glanced at Liu Chi in the window, blinked, waved his hand and said with a little pride: "Brother Chi."
Written on his face: Surprise or surprise, surprise or surprise.
Ye Yuxin heard this and moved her head curiously.
A slender girl about 1.65 meters tall, wearing a white coat and a black hat appeared in Ye Yuxin's sight.
The jet-black hair directly covered half of her face and hung directly on her chest.
(Elf girl) four words jumped into Ye Yuxin's mind.
"Okay, now you have learned how to play with surprises. I think you deserve a beating." After a few seconds, Liu Chi came to his senses and glared at the girl: "Get in the car."
"Hehe." Zhou Meng made a face, and finally got into the passenger seat obediently.
"Where is the luggage?"
"The Chiba Hotel not far from Huaqing." Zhou Meng buckled up his seat belt honestly this time.
"Chen Fei, go to the Chiba Hotel first." Liu Chi said to Chen Fei who was driving.
"..."
"Daughter-in-law, let me introduce to you, Zhou Meng, my half-apprentice, the 'big brother' who came back from Europe's X-bridge University." Liu Chi introduced to Ye Yuxin, who had been silent next to him, and emphasized the word "big brother" when he said it.
Angry.
"Call me sister-in-law." After finishing speaking, she added three words to Zhou Meng.
"Hello, sister-in-law, you are so beautiful." Zhou Meng turned around and looked at Ye Yuxin with envy.
"Hello." Ye Yuxin nodded with a smile.
"What's going on? You don't know how to say hello first when you come back? Can you change your character? If something happens, how will I explain it to your parents?"
"This is what I call true temperament." Zhou Meng retorted unconvinced: "Since China is not Africa, why should I be afraid? How can someone sell me?"
"With your bad temper, be careful not to find a boyfriend."
"Who can say, although I don't have one now, there will be someone waiting for me in the future, waiting for me to meet him one day." Zhou Meng said arrogantly, with words written on his face: Compare your heart, compare your heart...
...
"King of Yama." Liu Chi slashed with his backhand.
"Pfft..." Ye Yuxin at the side puffed and couldn't help but laugh.
"Stinky Liu Chi, damn Liu Chi, you bully me." Zhou Meng bared his teeth and claws. If it weren't for the seat belt, he would have rushed over. When he saw Ye Yuxin beside him: "Sister-in-law, look at this guy again
Bully me."
"Liu Chi, you don't know how to give way to sister Zhou Meng." Ye Yuxin now started to like this little sister with a straightforward personality.
"Let?" Liu Chi glanced at the two of them and snorted: "This girl will rub her nose and face in a while."
"How can I do that?" Zhou Meng shouted that he was wronged.
"Do you think this is the first day I've met you?" Liu Chi rolled his eyes.
"snort!"
"..."
"Boss Chiba Hotel has arrived."
"Uh..." Liu Chi stopped talking, looked out the car window, turned back to Zhou Meng and asked, "Is this here?"
"Um!"
"Yuxin, wait for me here while Zhou Meng and I go up to get our luggage." After Liu Chi finished speaking, he added: "You find a place to rest here for a while. We will come down in a while."
"Well, you go ahead!" Ye Yuxin nodded.
"Big Brother Zhou, let's go!" Liu Chi opened the car door.
"oh!"
Ye Yuxin looked at the two people who disappeared at the door, and decided to ask the girl who suddenly appeared when she got the chance. She said to Chen Fei who was driving: "Find a parking space and wait slowly."
"Okay!" Chen Fei nodded.
Chiba Hotel 706 Business Suite.
"Brother Chi, would you like some water?" Zhou Meng took a bottle of water from the counter and handed it to Liu Chi.
"It's such a cold day, you want to freeze me to death?" Liu Chi said with disdain. After looking around the environment, he felt pretty good. He walked to the sofa and sat down: "How long have you been back?"
"Last night."
"Don't call me?"
"It's midnight, I'm afraid you'll scold me!"
"Come on, you girl. When were you afraid that I would scold you? Please clean up quickly. Your sister-in-law is waiting downstairs?" Liu Chi urged, looking at Zhou Meng who was standing stupidly.
"Hmm, wait for me." Zhou Meng stuck out his tongue and packed his luggage with the speed of seven or eight hands.
Ten minutes later!
Liu Chi pushed an oversized suitcase out of the hotel door, followed by a small tail carrying a bag.
When Liu Chi put his luggage away, he found that this girl Zhou Meng had occupied the back row!
I had no choice but to sit in the passenger seat.
He fastened his seat belt and signaled to Chen Fei that he could leave.
"Brother Chi, it's my birthday in a few days, what are you going to give me?" Just when Liu Chi was in a daze, Zhou Meng patted the back of the chair and asked.
"What do you want, girl?" Liu Chi turned around and asked.
"You have to think of the gift yourself, so that you can show your sincerity."
"Okay, I understand. I'll study it later." Liu Chi added: "I'll go to Times Square to buy you a skirt tomorrow."
"Hey, hey, hey... Why are you a big boss with tens of billions of dollars? Are you embarrassed to buy a dress? You are not rich." Zhou Meng pouted and said dissatisfiedly.
"Then what do you think? I'm the one going to buy hair after all. I'm such a big boss and I'm not sincere enough to buy a gift for you in person? If it were someone else, I'd just go to Taobao and buy one for 9 yuan and 9 free shipping.
"
"Stingy guy, drink cold water..." Zhou Meng said for a while, and saw Liu Chi ignoring him and busy pulling his teammates: "Sister-in-law, look at Brother Chi, he has been like this since he was a child."
"Can you touch your conscience when you speak?" Liu Chi said disdainfully: "Can you please have some shame?"
"..."
After arguing for a while, Liu Chi changed the subject and asked: "What are you going to do next? Are you going back?"
"I won't go back."
"What about your parents? Do they agree?" Liu Chi frowned and asked.
