Yu Tian talked about a way to increase the price and asked two questions about the motor.
Zhang Sitong was confused. "If the windings and magnetic circuits do not rely on electromagnetic interaction to generate energy, what other methods can we use? I only understand so much about motors, can you tell me?"
"Piezoelectric Ceramics."
Yu Tian touched his chin and said while recalling, "The inverse piezoelectric effect and ultrasonic vibration of piezoelectric ceramics can convert the microscopic deformation of the material into the macroscopic motion of the converter or slider through resonance amplification and frictional coupling. This is what I
The principle of the ultrasonic motor I just talked about."
Ultrasonic motor?
Ultrasound is ultrasound, and motors are motors.
What the hell are the two combined together?
What Zhang Sitong didn't know was.
Ultrasonic motors are a technology that was only broken in the late 1980s.
Its advantages are many.
Compared with traditional motors, ultrasonic motors have four major advantages: low energy consumption, small size, low noise, and good compatibility.
The most important points are energy consumption and volume.
Low energy consumption means lower usage costs, and many companies will definitely give it priority when purchasing.
As for the small size, it is even more important.
For manufacturers, this means that the cost of producing raw materials is greatly reduced, especially precious copper wires.
Just these two points.
It is enough for manufacturers and purchasers to reduce costs.
Look at the entire market.
At present, no motor manufacturer or even research institute can develop this emerging technology.
"But in this case, wouldn't the cost also be 30..."
Zhang Sitong felt that it was better to place a long-term order for Soviet motors.
"It's not as simple as you think."
Yu Tian shook his head and said, "The cost of the Soviet Union will also increase, and prices will increase in the future, even surpassing ours. And don't forget that if we develop our own research, it will not only be applied to the factory, but it will also make Mayor Feng look bad.
Adding glory and splendor to the scene, do you understand?"
Until then.
Only then did Zhang Sitong understand why Yu Tian was so popular with Mayor Feng.
This guy is not simple.
While he benefited himself, he also did not forget to add glory to others.
Best of both worlds!
What is this called?
This is the win-win that Yutian has always adhered to.
Use various interests to bind various people, and everyone will benefit. This is the core idea of ​​sustainable, healthy and stable development.
"Impressed..."
Zhang Sitong sighed, "This guy Liu Chuanhua is unpopular! He does not hesitate to hurt other people in order to benefit himself. For this reason alone, he is no match for you! But having said that, how should I deal with Liu Chuanhua in the future?"
"Whatever you should do, just do as usual. Continue to agree with him, or even scold me in front of him. It doesn't matter." After Yu Tian said that, he got the paper and quickly drew up a cooperation agreement.
Zhang Sitong didn't say anything, raised his hand and signed his name.
If Yu Tianzhen can make a breakthrough in ultrasonic motor technology, the profits will definitely be much greater than now.
Agreement signed.
His people also completely belong to Yu Tian.
This is also the first factory that Yu Tian has won since he came to the capital, which is of far-reaching significance.
"When you are selling clothes, I will take Xiao Gao to have a look. Forget what I said before when I mocked you. It is my fault. Liu Chuanhua is too vicious. I am afraid that he will harm me. Brother, please don't mind. See what happens to me in the future.
If you pay back, you're done."
Zhang Sitong left behind a few words and a bunch of gifts, and left with Xiao Gao.
After seeing them off, Yu Tian hugged Li Wanrou and pretended to be sorry, "Daughter-in-law, you, you, Xiao Tengfei was taken care of by you, and Zhang Sitong was taken care of by you passively. I don't have a chance to show off my skills. How can this be done?"
Woolen cloth?"
"Didn't you get me done..."
Li Wanrou said something witty and her face turned red.
"Hey..."
Yu Tian was speechless for a moment, rolled his eyes, and kissed her face hard several times.
The couple talked about Liu Lihong again.
Li Wanrou lamented that Yu Tian was a bit cruel, but she didn't think so.
"Why not?"
Yu Tian didn't want to say too much about Liu Lihong's rebellious nature, "She is too young and is always uncertain. She must practice hard."
She said it as if she were cultivating an immortal, which made Li Wanrou laugh.
"correct."
Li Wanrou asked, "When will the clothes be sold? Sister Mei also wants to see it on site."
Speaking of clothing, Yu Tian thought about it for a while.
The weather has gotten a lot warmer these two days.
In early March, the ice and snow have melted, people no longer need to wear thick clothes, and there are more pedestrians everywhere.
"Let's wait for three or four days. I'll check the weather forecast to make sure it doesn't catch up with sleet and sleet." He thought for a while and said.
"OK."
Li Wanrou stretched out her hand, took Yu Tian's hand, put it on her lower abdomen, and said softly, "If you touch it, it's a little swollen. Do you think it's a boy or a girl?"
"twin!"
Yu Tian wanted to do something in a hurry.
"No way..."
Li Wanrou interrupted, "I went to see Dr. Lan today. He said it's better to have less sex to avoid ectopic pregnancies..."
Yu Tian was a little depressed.
He had no choice but to continue teaching Li Wanrou and explain English.
Li Wanrou learns quickly.
She never forgets anything she has learned before. Her mind is bright and she is working hard towards Hua Qing.
to be honest.
In this era, it is not easy for women to get into college.
Not to mention a woman who is pregnant and carrying a child?
But Li Wanrou has this kind of spirit.
The time she spent walking around the campus of Huaqing University left an indelible impression on her.
Two hours later, Yu Shuang and Wang Dongyue came back with Doudou.
Doudou has been hanging around with them for the past two days, her little face is red, and her nose is filled with snot and bubbles caused by the evening breeze.
"How's the build going?"
Yu Tian welcomed him out and asked Doudou while wiping his nose.
"Everything is ready!"
Wang Dongyue grinned, "Just tell me a date. Xiaoyun and I will go to Beijing Film Academy to inform you then."
One mouthful of a little Yun, so called so affectionately.
Yu Tian quickly interrupted his thoughts, "Don't be ridiculous, I don't care if you get other women. Xiaoyun is a nice girl, don't fool her, do you hear me?"
Wang Dongyue is worried.
I almost died of sadness.
He sighed and said, "Brother, how could I have deceived her? She is dealing with me just like she deals with her third grandson. If you don't believe me, ask your second brother. I have done all the work in the past two days to set up the stage!"
"
Yeah?
Yu Tian looked at Yu Shuang.
"Hahaha!"
Yu Shuang nodded and laughed, "That's right, if Lao Wang dares to disobey, Xiaoyun will kick him! Xiaoyun is very ruthless and will kick him whenever he wants. He will be merciless."
That's okay.
Yu Tian no longer worries about the unstable factor of 'cousin'.
"Have a rest."
He said to the two of them, "Second brother, I will take you to the mall tomorrow to buy something for my second sister-in-law. When you get home, you can bring out a lot of gifts at once to make sure that she will not be angry with you again."
Wang Dongyue also wanted to go, but Yu Tian refused.
Yu Tian smiled and said, "Cousin, I'll get you money, and you can buy it when you get home. Don't be idle these two days, just take my son to play everywhere, so as not to cause trouble for me by messing around!
"
"All right..."
Wang Dongyue looked bitter and hugged Doudou, "My child, uncle can only coax you to play. Tomorrow, uncle will take you to the swimming pool. There are many beautiful big sisters there!"
Go to hell!
Yu Tian kicked him over, scaring Wang Dongyue so much that he ran away, making everyone laugh.
A night of silence.
Early the next morning, Yu Tian took Yu Shuang to Wangfujing Department Store.
Went in and walked around.
soon.
Yu Shuang stood in front of a gold jewelry store.
"Which one did you pick?"
Yu Tian asked.
"that."
Yu Shuang pointed to a golden phoenix on the counter and said, "How beautiful is it? Xiaofeng Xiaofeng, she is wearing this golden phoenix necklace, which means spreading her wings and flying high."
"Hahaha!"
Yu Tian praised, "Second brother, how come you still have so much fun? Aren't you afraid that Xiaofeng will really fly away and leave you?"
It's all a joke.
The two brothers giggled.
But it didn't come true.
At this time, Zhang Xiaofeng was preparing to say her final farewell.
