Huayu for engineering students

Chapter 86 A Kind of Concern

Wang Xu estimated that he didn't have 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 was running very steadily, as long as there were no orders, the second aunt and Tang Yun were enough to handle it.

Speaking of which, Ergu and Erunu's skills are really good. They are the traditional skills taught by masters and apprentices. Ergu was raised by a Gusu person, which is why she is obviously from Qinchuan. Instead, it has an 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, everything is the same, and the basic techniques and abilities are similar.

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

Coupled with various three-dimensional tailoring methods, the new tailoring methods have changed a lot, and these are different from what the second aunt and the others originally mastered.

But changing it is also about clothing. Once the second aunt and the others have mastered the basics, there is still no problem in taking pictures of cats and tigers, especially when Wang Xu provided a sample.

The life in the imperial capital made the second aunt and the second uncle very satisfied. As soon as they arrived, Wang Xu gave them a salary of 300 yuan and paid them a month in advance 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 salary, the couple will earn two thousand this month, and they are so happy that they laugh every day.

Tang Yun's job is to watch the store every day, learn English, and manage the clerks. It can be said that she has made rapid progress. In the absence of a permanent clerk, she manages all things in an orderly manner and has never had any troubles.

Even without a teacher, I figured out the relationship between inventory and sales. Through ingenious and reasonable arrangements, this tailor shop has never been out of stock, but the inventory has always been kept at an extremely low level.

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

Not only are there domestic ones, but she is also inquiring about new fabrics in the world. As long as they are domestically available, even if they are expensive, she will find some for Wang Xu, so that when he needs them, he will not be able to cook without rice.

Therefore, in the current tailor shop, Wang Xu hardly needs to worry about it, just divide the money every week, um, yes, divide it every week, the small shop does not need to keep too much money, it is pure waste.

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

This little beer girl from the countryside is changing rapidly all the time, and one day, she will break out of the cocoon and bloom endless youth.

Wang Xu booked a flight ticket for next week, and went to ask Professor Yan for leave. This time, he might go for a month without showing his face.

Professor Yan quickly approved the fake. He has already obtained the test result of the microphone, and he notified Wang Xu today.Unexpectedly, Wang Xu would ask for a long vacation, saying that he would go to Xiangjiang to do something.

Professor Yan knew that he could make troubles, but in the end, all the troubles went abroad.That's right, Xiangjiang is really a foreign country right now, administratively it belongs to Britain, and it won't return until 97.

Now there are signs of emigration. As 97 approaches, a large number of Xiangjiang people will emigrate overseas.The middle-class and small bosses with a little money ran away a lot, but the big bosses can live well wherever they go anyway, so they are not in a hurry.

All indicators of the microphone are good, surprisingly good.

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

Professor Yan dared to say that Professor Zhao Weimin of the Institute of Acoustics had to believe it, so he stopped his work and arranged for his students to give priority to careful testing.

The test results are astounding, such an apparently modified microphone has acoustic characteristics that the original does not have.

The acoustics department was shocked, because this microphone is top-notch in terms of sensitivity and frequency response, comparable to the best products in the world.

Its high-fidelity and high-sensitivity features are even more excellent, and it can sensitively collect very small and weak sounds, um, so they thought about it, and then passed the news up, and then they couldn't write.

But these have little to do with this article, and it has to do with Wang Xu, but it doesn't have much to do with it.

"The microphone you made may be used by higher authorities. After you apply for a patent, you will be rewarded. I don't know the exact amount. The patent process will probably be faster. But anyway, it doesn't involve civilian use, and there are no restrictions, so You can rest assured.

I think that the circuit you designed is very distinctive, and it feels that it should not only be used in the field of microphones, so you can 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 it 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, which is a good thing.

This kind of attention, in fact, has almost no direct benefits, but, when it is not guaranteed, someone will take care of it, which is a tacit type.It is more transparent now. If it was used before, it would not tell you even if it is used, but that kind of attention has always existed.

"Okay, anyway, I'm just a primary school student, with thin arms and legs, so I don't pay attention to those things, just continue to toss around on my own." Wang Xu said haha, there is someone in the family who is out of the house, don't make yourself out of it home is fine.

"What did you mean last time when you said that this microphone is only a semi-finished product? Do you still have a plan for improvement?" Professor Yan continued to ask with a smile.

"I have some ideas, mainly the membrane. I want to change it. Can you borrow a laboratory for ion vacuum evaporation? I have an idea and want to try it. It won't take long, it will take half a day." Wang Xu kicked his nose On the face, this time is of course a step forward.

"It 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 has to be redone, the equipment has to be redesigned, and it is very troublesome to prepare. Wait for me to come back from Xiangjiang. I want to find a more convenient method of thin film production. The current membrane is still a bit thick. "

"You can really make troubles, no wonder the old side told me to let you change departments, which made me toss about the film material again."

"No, it's fun to do materials once in a while, but it's boring to do it every day. If you allow me to mess around, I'm afraid that Professor Bian will let me do materials alone, and it will be hard work." Wang Xu complained. , by the way flattering.

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

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