Chinese entertainment for engineering students

Wang Xu estimated that there wouldn't be much to do in the imperial capital, so he planned to go to Xiangjiang to meet Wang Fei. To be honest, he missed her a little.

The tailor shop is running very smoothly. As long as they don't accept custom orders, Ergu, his wife and Tang Yun can cope with it.

Speaking of which, the second aunt and the second uncle's craftsmanship are really good. They are the traditional skills taught by masters and apprentices. The second aunt was simply raised by a Gusu person. This is why she is obviously from Qinchuan. Instead, he has the accent from Gusu.

Although traditional crafts are not very compatible with modern tools, once you get started, you can learn them very quickly. After all, they remain the same, and the basic techniques and abilities are similar.

The main difference is still reflected in the pattern. In addition to various advanced sewing machines, the development of modern clothing is also about the rapid advancement of tailoring. Western-style traditional clothing pays more attention to self-cultivation, while modern simple clothing has different shoulder shapes and different processing methods.

Coupled with various three-dimensional tailoring methods, the new tailoring methods have become ridiculously varied, which are all different from what Ergu and the others originally mastered.

But again, it’s all about clothing. Once Ergu and the others have mastered the basics, there is no problem in copying the cat and the tiger, especially when Wang Xu provides a sample.

The life in the imperial capital made the second aunt and second uncle very satisfied. As soon as they arrived, Wang Xu gave them a salary of 300 yuan and a month's advance payment so that they could settle down.

This salary is actually higher than that of ordinary civil servants in the imperial capital. Oh, by the way, they are not called civil servants at the moment.

Coupled with the piece-rate wages, the couple earns just over two thousand yuan this month, making the couple smile every day.

Tang Yun's job is to look after the store every day, learn English, and manage the store clerks. It can be said that she has made rapid progress. Without a long-term store clerk, she has managed everything in an orderly manner and has never had any problems.

He also understood the relationship between inventory and sales without any teacher, and through clever and reasonable arrangements, the tailor shop never ran out of stock again, while the inventory was always kept at an extremely low level.

According to the latest report, she has begun to contact various fabric suppliers, looking for various new fabrics that Wang Xu needs.

Not only are they available in China, but they are also inquiring about new fabrics in the world. As long as they are available in China, even if they are expensive, she will find some for Wang Xu, so that when he needs them, he will not be overwhelmed by the skillful woman.

Therefore, Wang Xu hardly needs to worry about the current tailor shop. He can just divide the money every week. Well, that's right, divide it every week. Small shops don't need to keep too much money. It's just a waste.

This has also made Tang Yun's life significantly better. Tang Yun's various bags, shoes, and various small accessories are all changing rapidly at a speed visible to the naked eye.

This beer girl from the countryside is changing rapidly all the time. One day, she will break out of her cocoon and blossom into endless youth.

Wang Xu booked a flight ticket for next week and went to ask for leave from Professor Yan. This time he might be away for a month without showing his face, so it was unjustifiable not to ask for leave.

Professor Yan quickly approved the fake. He had already obtained the test results of the microphone and informed Wang Xu today. Unexpectedly, Wang Xu actually asked for a long leave and said he would go to Xiangjiang to do something.

Professor Yan knew that he could do things, but in the end, he had to go abroad. Yes, Hong Kong is really a foreign country at the moment. Administratively, it belongs to Britain and will not return until 1997.

Now there are signs of a wave of immigration. As 97 approaches, a large number of people from Hong Kong will gradually immigrate overseas. The middle-class people and small business owners who have some money run away a lot, but the big bosses can live well wherever they go, so they are not in a hurry.

All specifications of the microphone are very good, surprisingly good.

Since it was an old friend who called me personally to ask for the test, he also specifically stated that this microphone may be top-notch. Yes, Professor Yan said so. I don’t know why he believed Wang Xu so much and dared to say this directly. .

Professor Yan dared to say that even if Professor Zhao Weimin from the Institute of Acoustics didn't believe it, he stopped what he was doing and arranged for his students to conduct careful testing first.

The test results are shocking. Such a clearly modified microphone has acoustic characteristics that the original product does not have.

The acoustic institute was shocked, because this microphone is top-notch in terms of sensitivity and frequency response range, and can compete with the best products in the world.

Its high-fidelity and high-sensitivity characteristics are extremely outstanding, and it can sensitively collect very small and weak sounds. Well, so, they started to associate it, and then handed over the news, and then they couldn't write it down.

However, these have little to do with this article. They have something to do with Wang Xu, but not much.

The microphone you made may be used by the higher-ups. After you apply for the patent, I will give you some compensation. I don't know the specific amount. The patent process will probably be faster. But anyway, it does not involve civilian use and there are no restrictions, so Don't worry.

I think the circuit you designed is very unique, and it feels like it should be used in more than just the field of microphones, so just leave it alone.

Professor Yan explained to Wang Xu with a smile, and then took out an agreement. Wang Xu looked at the red letterhead, glanced at it, and signed directly. There is no need for him to know too much about this kind of thing, but he also understands that someone is paying attention to it, which is a good thing.

This kind of attention, in fact, has almost no direct benefits, but if the protection is not complete, someone will take care of it, which is a tacit type. It's more transparent now. In the past, I wouldn't have told you even if I used it, but that kind of attention has always been there.

Okay, anyway, I'm just a primary school student with thin arms and legs. I don't pay attention to that. I just keep messing around. Wang Xu said haha. There is a person in the family who is homeless. Don't make yourself in trouble. Home is good.

What did you mean last time when you said that this microphone was only a semi-finished product? Do you have any plans to improve it? Professor Yan continued to ask with a smile.

I have some ideas, mainly the membrane. I want to change it. Can you help me borrow a laboratory for ion vacuum evaporation? I have an idea that I want to try. It won't take long, just half a day. Wang Xu sniffed. On the face, this is of course a step forward.

This does exist. When do you plan to use it? The material department has it. Do you plan to coat it yourself?

Well, this is not urgent. The membrane needs to be remade and the equipment needs to be redesigned. It is very troublesome to prepare. Wait until I come back from Xiangjiang. I want to find a more convenient way to generate the film. The current membrane is still a bit thick.

You are really good at twisting and turning. No wonder I asked you to switch to another system, which means you are messing with membrane materials again.

No, it's fun to work on the materials once in a while, but it's boring to do it every day. As long as you allow me to mess around, I'm afraid that Professor Bian will force me to just work on the materials, which will make me miserable. Wang Xu complained. , flattering by the way.

Oh, by the way, I thought of a method of making membrane materials, but it may require an electron microscope. Can we rent this thing? Wang Xu continued to ask, this was his ultimate goal.

It's not impossible, it's just very expensive, but it shouldn't be a big deal to you. You have to ask a professional operator to operate it. They can only take pictures for you and then analyze it yourself.
