Shen Yiyi asked Luo Yufeng to help her go to several research institutes in Shanghai before returning to Shenyang. She didn't think about the possibility of a holiday, and the research institute would have to take a holiday and stop working. In addition to the selection of the wing shape and the selection of the power source, the first problem that needs to be solved is what materials to use to make the paramotor. As an inflatable structure, the material must be soft, but not elastic such as rubber, and have a good seal, and more importantly, it must be strong enough to avoid breaking or leaking when inflated or flying in the air. If you are really engaged in the research of a scientific research project, it will take a lot of effort to find such a material. In such an era when there is no Internet and no sufficient information, you can imagine how time-consuming and laborious such a job is. However, at this time, the role of Shen Yiyi, an engineering woman who traveled through later generations, was reflected. Her superficial understanding of paramotor in later generations allowed her to propose what kind of fabric to choose at that time.

Luo Yufeng's instructions to Shen Yiyi are basically resolutely implemented now, and she has tasted the sweetness from the last time she cooperated with Shen Yiyi on the "school uniform", so she intuitively thinks that the favor that Shen Yiyi asked her to help this time may also be an opportunity for her. Even if he may not be able to get any benefits from it this time, at least he can make Shen Yiyi owe himself a favor. The personal debt between Chinese is the most difficult to pay off. is as shrewd as Luo Yufeng, and even thinks that being able to make others owe him favors can help him win a lot of contacts.

Since Shen Yiyi has a request now, Luo Yufeng will of course go to several textile research institutes or chemical research institutes in Shanghai the next day. She didn't know anything about the material knowledge anyway, but she just firmly remembered the name of the material that Shen Yiyi mentioned to her on the phone: nylon 66. Later generations of China, the world's leading factory. Paramotor has become a kind of sports equipment that is mostly made in China. When Shen Yiyi was chatting with a colleague's boyfriend, the small boss of a sports equipment company talked to her about the fabric of the umbrella. Therefore, Shen Yiyi has a deep memory of this material called nylon 66. Her only concern is whether there is such a material in China in this era. If there is no such material in the country. And if it has to be imported, then the cost is difficult to say.

As a nylon material, if it is to be used on umbrella cloth, it cannot be in the form of ordinary pellets. Shen Yiyi ultimately wanted a form of textile fabric. Shen Yi prayed that Luo Yufeng could find the fabric woven from this material in Shanghai, and at the same time sighed that material science and technology are really the basic disciplines of human progress. Without the progress of material science, it is impossible to pursue the achievements of industrial civilization.

Fortunately, a day later, when Shen Yiyi came to Luo Yufeng's garment factory again. received a call back from Luo Yufeng. On the phone, Luo Yufeng happily told her that a researcher from the Shanghai Textile Research Institute had just completed a nylon 66 fiber project last year, and had really made some fabrics made with this as a raw material for the completion of the project. Shen Yiyi was overjoyed to hear the news. She hurriedly asked Luo Yufeng to ask the researcher to get some samples and come back for mechanical analysis, and then it was best to keep in touch with the teacher, and it was best to leave the contact information or something. Once the test is passed, it means to ask the teacher to order more such fabrics.

Luo Yufeng was also happy on the other end of the phone: "Sister, your sister Luo and I are doing things, aren't you still at ease?" What you think, Sister Luo has already done it for you. Mr. Chen is also very happy. His project is about to be concluded, and there is a lack of proof of application. If you can help him apply the research results and give him a proof, there will be hope for him to apply for the second prize at the ministerial level this time. ”

Shen Yiyi secretly rejoiced. God help me. If you just want to fall asleep, you can send a pillow. She thought about it and asked Luo Yufeng: "Sister Luo, I forgot to ask." Did Mr. Chen offer you a price, how much is a meter of fabric? Will it be expensive? ”

Luo Yufeng smiled and said, "Okay." Girl, I'm here with Mr. Chen. Why don't you tell him yourself? ”

Shen Yiyi was a little surprised at first, but then it was normal to think about it. In an era before mobile phones, it was not so easy to make a long-distance call. Long-distance calls are expensive and difficult to make at this time. A shrewd person like Luo Yufeng, of course, has to find a public unit to call. Chinese bars like to rub the oil of the public.

After the phone was answered, there was just a "hey" from the other side, and Shen Yiyi hurriedly greeted him warmly on the other end of the phone: "Hello Mr. Chen!" I'm Shen Yiyi. ”

Mr. Chen is still very reserved like an intellectual, and just replied lightly: "Oh, hello." ”

Shen Yiyi was not enthusiastic when she heard the tone in the microphone, but she still said in the same enthusiastic tone as before: "Teacher Chen, that's the case, Sister Luo has told you." We have a project that has the potential to use nylon-66 material......"

Regardless of whether Luo Yufeng has already confessed to others before, as a courtesy, it is also appropriate to introduce the situation on his side in detail again. Moreover, this behavior also has a psychological suggestive effect, which can make the other party lower their guard against unfamiliar sounds. Later generations of telemarketing and scam calls have made effective use of this telephone tactic that incorporates psychological principles.

Mr. Chen was also apparently inevitably influenced by this phone strategy. After Shen Yiyi introduced the specific situation of his project, he was also a little happy that it was possible to use the new fabric he researched in a field that he had never thought of. The main application object of textile fabrics of the Textile Research Institute is clothing. However, if this kind of chemical fiber fabric is used in clothing, the first problem is that it may not be very comfortable to wear, and it cannot be used for high-end clothing at all. Mr. Chen was worried, such a fabric that had spent money to apply for the research of the subject, and could not find the application object at all, so when he couldn't write the application prospect and social and economic benefits in the summary report, he heard Shen Yiyi say that she could use it here, which was really a feeling of sending charcoal in the snow. Especially when I heard that Shen Yiyi may be used on a flying umbrella, and then I think that Shen Yiyi's city is Shenyang, Mr. Chen's automatic association linked the use of this fabric to national defense.

This brain supplement made Mr. Chen very happy. If the results of your research can be used for national defense. Isn't the social and economic benefits of your own research summary report coming out? Maybe the award you applied for can be upgraded to the next level. Thinking about this, Mr. Chen was obviously much more enthusiastic than he was at the beginning. Shen Yiyi could even hear from the phone that Mr. Chen's breathing was a little short.

"That. Comrade Shen Yiyi, so be it. If you want to use these nylon-66 fabrics that I tried to weave, I will give them to you for free. But if you use it and think it's good, you have to give me a proof of application, which we need to use for the award. ”

"No problem." Shen Yiyi really didn't think this was a difficult matter. Isn't it just a certificate and a stamp? The easiest thing is to ask Luo Yufeng to give a certificate. In a privately contracted factory like hers, all unit seals and financial seals are in Luo Yufeng's hands, and it is not easy to stamp a seal. Even Shen Yiyi was still thinking that if the paramotor was successfully made, she was saying that she would be able to let her father use it to affirm her contribution. Let's see if I can get Dad's troops to give a proof, then the proof will be stronger.

"Teacher Chen, in fact, what we are concerned about here is whether your fabric is enough. You know, we use a lot. "You know, the material area of an umbrella may be as much as 100 square meters.

Teacher Chen didn't take it seriously: "No problem, don't worry." Comrade Shen Yiyi, as long as you can provide us with application examples, I will give you as many fabrics as you want. You know, our refining furnace has an initial refining capacity for this chemical material. Our furnace has a starting plate of 5 tons. If you think about 5 tons of material, how many square meters of fabric can I weave here? So if you really need it, I'll just weave you some more cloth here. ”

As soon as he said this, Shen Yiyi had no worries at all. Apparently the Shanghai Textile Research Institute at this time. There is still no marketization of scientific research. This Mr. Chen has no economic consciousness at all, and is completely in order to complete the research report and declare an award or something, so he will not ask for any economic compensation for the material requirements he puts forward, but only ask for an application certificate. Shen Yi sighed and despised himself. Obviously, I was so happy in my heart that I was still worried about the benefits of this Teacher Chen's achievements. In fact, based on Shen Yiyi's own experience in later generations, completely market-oriented scientific research is not an ideal approach in China. China as a backward country. Originally, the level of research was much behind that of the West, and each unit was purely motivated by its own interests. The slightest progress in research is taken very seriously, and it is kept secret from other units. Either the high price is demanded, but it hinders the application of new technologies, or causes a lot of duplicate investment or research, wasting the country's scientific research funds. It is important to know that the greatest breakthrough period in China's science and technology was precisely formed under the system of high-level planning and planning with the strength of the whole country. Therefore, in terms of scientific research, the planning system and the national system are not necessarily bad. Even Shen Yiyi thinks that scientific researchers should be raised by the state, and they don't have to worry about their livelihood, as long as they devote themselves to research. The matter of commercial promotion should not be considered by scientific researchers, but should be left to pure businessmen.

On the contrary, under the market economy, scientific researchers also have to consider what to do to study quickly with money, which is the fundamental reason for the overall impetuousness and utilitarianism of China's scientific community in later generations, and the long-term stagnation of the most time-consuming and laborious but extremely important basic scientific research. The problem in the scientific research system is not that some so-called economists or sociologists who do not know how to pretend to understand and love to express their opinions are criticized for not being market-oriented enough, but precisely because the full competition under the marketization has weakened our country's already weak research and development strength and increased internal friction. If it had been the kind of system in the fifties and sixties, maybe the heart disease would have been solved a long time ago. Shen Yiyi never thought that the market economy was a panacea. Economically, the market economy may play a positive role, but in scientific research, especially when catching up with the West, we must concentrate our efforts on doing great things.

Of course, people in society cannot ask society to adapt to themselves, but only people can adapt to society. So Shen Yiyi sighed a little, and immediately finalized it with Mr. Chen on the phone, and waited for Luo Yufeng to bring the sample back, once the mechanics and physical and chemical tests passed, Shenyang immediately called Shanghai to inform the dosage of preparation, and Mr. Chen sent it over when he was ready.

The two sides have each other's needs, and of course they will hit it off. So at the request of Shen Yiyi, Luo Yufeng simply signed a memorandum with the Textile Research Institute in Shanghai to record the consensus of the two sides. What Shen Yiyi didn't expect was that her request made Mr. Chen sigh even more, it turned out that Shenyang was still very thoughtful and standardized, which strengthened her determination to support her paramotor project.
