"You spoke in more detail than the experts in the provincial capital. He Haichuan listened to Yang Rui's drawings for half an hour, and replaced "you" with "you".

Yang Rui is younger than him, and he can't stand the high-end of others. Just listen to the detailed process of his answer to the question, you can know that this kind of exposition that can even say the "one, two, three" points from the welding angle must have real talent and real learning. If you ask "you" or "you" for advice, He Haichuan himself blushed.

Ning Min, who entered the factory a year later than He Haichuan, was even more stunned, and the experts in the province said conclusively that "we are not yet capable of making our own" high-end machine, which was eloquent in Yang Rui's mouth, and it was clearly organized, the arguments were detailed, and their experience on weekdays was very similar.

It's not amazing, it's scary.

According to the standards in the drawings, this machine is made of QÌ, if not as good as the high-end models of the Germans, but also better than their low-end models.

In other words, Yang Rui can draw machine drawings worth tens of thousands of dollars with his bare hands, which the meat factory can't afford to buy.

When they couldn't understand the drawings when they got them, they actually came to Yang Rui to ask for the original information from him.

Now, Yang Rui not only perfected the diagram, but also kept explaining the key points of the process, simply saying every key step encountered in production.

Moreover, when He Haichuan asked, Yang Rui could write super difficult formulas casually.

Crystallization thermodynamics, thermal analysis kinetics, crystallization kinetics...... These things sound like rap, and the content in them is naturally more winding.

When it came to this part of the content, Ning Min couldn't understand it at all, He Haichuan had more contact with technology than him, and he was relatively clever, but he couldn't do it with the same difficulty, he could only say that he knew what he said, and then wrote it down in his notebook, ready to take it back and study it slowly.

Of course, this is just a good wish.

Although the two drawings drawn by Yang Rui are a machine with a scientific and technological level in the 80s, its popularity in China has actually reached the 90s, and it is a seemingly simple and mature product, but in fact it is quite a technical product - in fact, with the technical level of the domestic 80s, what evaporator is taken out, it is quite technical.

Crystallization thermodynamics is to crystallizers what aerodynamics is to airplanes and hydrodynamics to submarines, unless you want to produce a World War I-level product.

If it is a normal research institution, although crystallization kinetics is troublesome, it is just a physical job that requires a brain, and any researcher with a level can understand it.

However, at this time, it is normal for several domestic research institutions to have them.

Yang Rui soon discovered that although there are some big bulls in China who can solve this kind of problem that many people can't solve with computers in a purely manual way, the two in front of him are not big bulls.

He Haichuan's Cheng dù is a little better, that is, the level of undergraduates who passed the long live in later generations, but Ning Min is a technician type, he has a headache when he sees mathematical formulas, and he can still listen to the key points of the process when he explains them.

So, two minutes after the principle was said, Yang Rui didn't bother to answer the basic questions, patted He Haichuan, and said, "Okay, don't remember, you either do it the way I said, don't worry about the principle." ”

He Haichuan was embarrassed and whispered, "It's me who is too stupid......"

"It's nothing stupid, dynamics is originally a tossing thing, among the 100 college students, 95 don't know what to learn after the exam, and the remaining five, if one person is proficient in applying it, even if there is no waste of class time, you can make things, don't you complete the task?" When Yang Rui was studying, he was relatively talented in this area, belonging to one percent of the little geniuses, and when he graduated from his senior year, he could calculate the dynamics formula on the computer by himself, so he strengthened his heart to study in graduate school.

It is a pity that in China in the 21st century, six or seven million undergraduates and five or six hundred thousand graduate students graduate a year, and the total number of research positions is only 2 million.

In contrast, the 80s could not have been happier, with only two or three hundred thousand college graduates a year, and very few graduate and doctoral students.

Not to mention college students, Xibao Meat Factory is also a state-owned enterprise at the prefectural and departmental level, and students like He Haichuan can engage in research with their intelligence, which is a treatment that graduate students who work in private enterprises do not have.

At this moment, He Haichuan looked at Yang Rui with admiration, nodded again and again, and said, "Let's go back and do the preliminary practice." There are a few pieces of equipment that are not available, but should be able to be borrowed. ”

Yang Rui bowed: "It's easier to make this thing than to understand it." ”

"I didn't expect you to see so much...... Extracurricular books. He Haichuan really didn't know what to say.

Yang Rui couldn't cry or laugh, touched his head, and said, "It's probably a little unprofessional." ”

"At your level, when you return to Xibao in a few years, you will definitely have to come out to greet our leaders. He Haichuan patted a little fart.

Yang Rui is quite comfortable to listen to, if you feel uncomfortable after being patted, then you have to find two reasons: the sycophants are not good, or, I'm a pervert!

He Haichuan obviously knows how to fart, and he took advantage of the situation to make another move: "When I saw you in the reading room, we guessed that it was a college student from the provincial city who came to help, you are tall, like a movie actor......"

Yang Rui continued to secrete dopamine, and said coolly: "What else do you want to say, just say it, don't beat around the bush." ”

He Haichuan smiled embarrassedly and said: "I just want you to help me write a simple explanation, you know, self-made evaporators also have to be funded, if there is no explanation, the above will not be recognized." ”

If you really want to make a drawing, even a simple explanation will take two pages.

Yang Rui didn't want to bother too much, thought for a moment, reached out for a pen, and wrote a formula with a brush.

The formula is very long, and there are * letters representing different variables, as well as triangles representing the amount of change and a string of large, medium and small parentheses.

Yang Rui finished writing a few times and said, "Whoever wants to explain, you will give him this." ”

"What is this?"

"The crystallization kinetics in the evaporator are basically in it, and those who can understand it naturally know what is right and wrong, and if they can't understand it, you say you can't understand what explanation he wants, right?" Yang Rui smiled narrowly.

He Haichuan smiled and said, "If there is anything I don't understand, can I come and ask you?"

"Yes, but if you ask questions for so long, I have a request. ”

You say. ”

"I also wanted to make a crystallization, but it was not quite the same as this one, which was on another drawing I made. If you can make one for me, I'll help you along the way. "Yang Rui didn't mention money, but he didn't talk about money when he was short of money in this era.

However, it would be a mistake to think that people are all living Lei Feng. To put it simply, businesses and individuals in the 80s liked to barter.

Canned food, food stamps, fruits, cotton cloth, whatever you give, in fact, it is more affordable than money, because now it is a ticket system, and a national food stamp of 10 kilograms of white flour is better than great unity.

The secret of the so-called welfare lies in this. Welfare not only has grain, oil, rice and flour and other things, but also good things that money can not buy, such as state-owned enterprises such as Xibao Meat Factory, in the spring send a car to the east to buy hairtail to buy large yellow croaker, in the summer to send a car to the west to buy cantaloupe to buy raisins, in autumn to send a car to the north to buy sheep and cattle, in winter to send a car to the south to buy citrus and buy grapefruit, all of the top are picked out of the big and thick organic products, some profitable factories almost every month have something to do, the factory car fleet is also a constant flow in the north and south of the motherland. In terms of quality of life, in the 80s, except for the poor electrical appliances and housing conditions, it was much more comfortable than the monthly salary of more than 10,000 yuan in later generations.

Because of this, the state-owned enterprises with good profits in the 80s were all first-class good units, and they were good places where the county party committee and district committees were not replaced, and they belonged to the upper class of society.

But on the other hand, if you want a state-owned enterprise to give money to an individual, even if it is tens or hundreds of yuan, it is very difficult.

Yang Rui estimates that the material cost of making a crystallizer for a real room is more than 1,000 yuan, and he can afford it himself, but he can't buy it, and the materials, equipment and labor are difficult to solve.

He can shake a flask, but he doesn't use a welder.

Moreover, even if he asks for money, Xibao Meat Factory will not give it, maybe the asking price of 100 yuan will have to be discussed, and if it is not good, it will affect the uncle.

But it's different if you want something, especially if you can't sell it at first glance, the other party is likely to agree.

He Haichuan didn't feel too embarrassed, nodded and said: "The drawings you drew are also reasonable to make one for you, so I will report to the leader when I go back, if the leader does not agree, I will find someone to help you weld in private." ”

The factory costs money to buy materials, but the materials that can be moved into the workshop are not counted as money.

Yang Rui is also very happy, there is always a need for crystallizers in the room, which can also save a lot of money.

He Haichuan and Ning Min reluctantly said goodbye, and before they left the school, they were arrested by the parents of the students who had been waiting for a long time.

These workers from the Xibao Meat Factory have too many questions to ask.

He Haichuan and Ning Min also finally experienced the feeling of constant problems.
