Riding the wind of rebirth

Dinner is simple. There is a very good noodle restaurant next to the building for foreign students. Zhou Zhi and Fu Xia often come here for the toothbrush festival.

After dinner, Zhou Zhi bid farewell to the satisfied Guan Tingting and the others. The little girls were riding bicycles, so he didn't need to accompany them to school.

Hu Rui also carried Li Yijia's guitar on her back, and she was going to take it to the college for appraisal and maintenance by professional teachers.

Afterwards, he sent Liang Hong and Zhang Lu to the bus station, and made an appointment to call Yan Xiao another day, and then went to the stadium with Zhao Zhigang to watch the ball.

After a busy day, it was finally time to calm down. Zhou Zhi carried his schoolbag and went to the lecture theater to find a place to write letters to Jiang Shuyi and others.

A pager is still a luxury, especially for students. There is only one phone per dormitory building. Unless Zhou Zhi wants to hear Jiang Shuyi's voice, she will call her dormitory. Usually it is a letter contacts.

The same is true for the contact methods with other friends. Even Zhang Lulianghong and Zhou Zhi like to communicate with them in the same city. They can receive them within a day, which is actually quite convenient.

But Guan Tingting now also has paging, both of them are Hanxian, basically just text messages to greet.

For this reason, Guan Tingting even made a fuss and asked Zhou Zhi to write to her, but she never replied, just for the fun of receiving letters.

Another interesting phenomenon is that many classmates who were not close to Zhou Zhi in high school also wrote letters to communicate. In the end, Zhou Zhi contacted Jiang Shuyi, Zhang Xinyi, Ye Xin, Liang Hong, He Shiqing and others After a while, let them contribute the addresses of the classmates who wrote to them, add their own, and finally make a classmate list, and then send a copy to the classmates.

Don't ask Zhou Zhi why she knows that they have many classmates' addresses in their hands, because many things that she didn't dare to say in person in high school, she became daring to say in letters in college and junior college, so these beauties have classmates in their hands. The address is much more than that of Zhou Zhi.

In the letters to Jiang Shuyi, there are basically no personal details, mainly concerned about life and study, because Zhou Zhi knows that most of these letters will also be "shared" by Zhang Xinyi and Ye Xin, private words can only be said during the phone conversation .

Then I also want to talk about the big things on my side, not the big things that Zhou Zhi is doing, but the things that happened to people who are familiar with Jiang Shuyi, which can be regarded as the big things in the letter.

For example, Liang Hong and Zhang Lu's visit today, as well as writing a song for Guan Tingting and preparing to film a TV show for Sister Xiaojuan, are considered major events.

Another big thing is that Su Datou has settled down in Jingyang, and he has made a great contribution recently.

Jiang Shuyi is Su Datou's senior at Rongshan Central School, so she has always been more concerned about him.

It is also miraculous that Su Datou made great contributions.

After the baby arrived in Jingyang, Cousin An Ran threw him in front of the machine tool and learned how to be a fitter from an old worker.

The third sister Su Ziyuan and her brother-in-law Liu Dachuan have also developed very well in Qianzhou in recent years. They settled down completely and gave birth to a child named Liu Xiaocheng.

Liu Dachuan also worked as a senior engineer in the CNC machine tool factory, but recently encountered a difficult problem, that is, the square wave pulse of the imported CNC machine tool will cause great damage to the cutting wire from scratch, and will greatly shorten the cutting time. Cutting wire life.

To solve this problem, it is not difficult from a technical point of view, just change the rising phase of the square wave into a smooth curve.

But when it comes to circuit design, it is a bit complicated. Liu Dachuan couldn't figure it out, so he wrote to his cousin An Ran for help.

Cousin An Ran called a group of designers, and finally the circuit was made, but it was a bit complicated, which would increase the cost of CNC machine tools.

No matter what, things are available, and Jingyang R&D Center also has CNC machine tools. Cousin An Ran brings people to the workshop to install circuit boards, and is going to test the effect.

The test results are satisfactory, and it is expected that the life of the cutting wire can be extended by five times through this method.

Cousin An Ran was very happy and planned to use it for himself first.

Then the old workers felt baffled, the machine tool in our center, Xiao Su has already solved this problem?
Cousin An Ran is stupid, that Xiao Su?
Su Ziqiao, Xiao Su only replaced a small part for the machine tool, not only the effect is the same as yours now, but also...

And what?
And the cost is reduced.

A group of technicians suddenly felt insulted, impossible!Absolutely impossible!

Really!The old worker said to open the cabinet, you see, just replace the capacitor of the power supply line with a traditional paper-wrapped capacitor, and the electrical performance of the capacitor itself can be used to change the square wave into a smooth sawtooth wave. We saved a lot of money too!
Replace imported MKP capacitors with traditional paper-packed capacitors... Then, this problem is solved? !

However, after testing, this problem is really solved.

Although the cost reduction is a bit exaggerated, the total reduction is about ten yuan, and the working curve is not as perfect as the newly added circuit, but considering the combination, changing the capacitor is undoubtedly a whimsical and absolutely efficient and simple design.

Afterwards, Cousin An Ran praised Su Datou severely, wrote a letter to the whole family to praise him, and notified the whole group as a classic case. Workers learn from experience.

Su Datou is always mischievous and playful, I believe Jiang Shuyi will be happy for him seeing this.

After finishing writing the letter, Zhou Zhi's pager vibrated, and when he took it out, it was a text message from Tang Qi, expressing his gratitude to him.

So Zhou Zhi packed her schoolbag and came out of the classroom, went to the mailbox at the school gate to drop the letter, and called Tang Qi: "Sister Qi, you are too polite, Tingting's business is not my business, how can I let you tell me?" Thanks."

"When Tingting met you, she met a noble person." Tang Qi smiled and said, "You are really talented, how can you even compose music?"

"I don't know how to compose music, I just hummed a chorus." Zhou Zhi said with a smile: "The rest are all thanks to Ruirui."

"The chorus is the essence." Tang Qi thought for a while and said, "Maybe the original creator understands the artistic conception of the lyrics better, so they deserve the corresponding chorus."

Zhou Zhi had no choice but to hesitate, he was ashamed to say that he used Jay Chou's rhythm, but just changed the chord.

Fortunately, Tang Qi didn't bother too much: "I'm looking for the teachers of the academy to make a soundtrack. They said that the song, the lyrics, and your arrangement design are all phenomenal."

"Pair it with the MV of your hometown Jiangyuan, I think the picture is beautiful." Tang Qi was a little excited, and said with a smile: "Tingting is talented, and she has encountered such a good song before entering college, and she has a good song. The big publicity of the advertisement, this is not meeting a noble person, how can it be considered as meeting a noble person?"

"Tingting is my student, and also a student of our college. Of course I want to thank you for being a great pusher." After finishing speaking, she couldn't help but giggled.

"Sister Qi is much more troublesome about the song, and sister Chi is more troublesome about the MV. Is she also very busy recently?"
