Chapter 29 The best sister-in-law in the 1980s (29)

Her natal family has money to engage in tidal flat farming, and Sister-in-law Xu has settled a worry.

Although it is said that a married daughter throws away water, but who doesn’t want the best for her natal family?

In the final analysis, it was her sister-in-law who helped her. Sister-in-law Xu was very grateful. Taking advantage of the abundance of food at home during the first month, she cooked various dishes for Xu Yin to eat.

Mother Xu muttered with a long face: "Using the things I bought to please your sister-in-law is really promising!"

Xu Yin couldn’t help but laugh when she heard this.

 Xu Zhinian returned to his work unit after finishing this matter. After the welfare housing is officially allocated, I can pick up my wife and children. I have to wait until spring.

On the tenth day of the first lunar month, Xu Jianjun brought two strangers to Xu’s house.

“Yin Yin, this is the night school mechanical class teacher I mentioned to you. This is Professor An, my teacher’s teacher, from the imperial capital.”

After listening to the introduction, Xu Yin understood their purpose.

I knew this day would come, but I didn’t expect it to happen so soon.

 She glanced at Xu Jianjun meaningfully.

Xu Jianjun felt numb when she saw him, and hurriedly cupped his hands: "Auntie, I know I was wrong."

At first he couldn't understand what he looked at horizontally and vertically. He thought that this should be taught in night schools in the county, so he signed up for a class. After class, he pretended to be a good student and asked the teacher. When he received the scholarship, he even laughed. How could he have thought of this? Drawings are so important.

Professor An and his colleagues came here mainly to see the solar-powered bicycle made by Xu Yin.

They followed the drawings and simulated it more than a dozen times, but none of them succeeded. They couldn't help but wonder whether Xu Jianjun's words contained moisture.

 The principles described in the drawings are indeed feasible.

After getting the drawings, the superiors also sent people to Xujiacun for an unannounced visit. Indeed, a senior engineer who had returned from overseas had lived in the cowshed.

From his background information, it can be seen that he did make relevant remarks during his years studying abroad, but they were all formless.

Perhaps it is the result of research and development after arriving in Xujiacun?

It’s a pity that the cowshed has been abandoned for many years. Even if valuable information has been left, it can’t be found now, except for this drawing.

That was picked up by a little girl in the village who was lucky enough to pick up stones. It is said that I picked it up and turned it in, but it was returned as trash.

 After verification, the relevant personnel have been punished, but to be honest, this drawing is something that even professionals like them cannot assemble after following it. Is this little girl really capable of doing it?

 She is only a high school student, right? And he is still a high school student in a rural middle school with relatively poor educational resources.

 They can't help but be suspicious.

Xu Yin sighed and pushed the bicycle out of the main room for them to see for themselves.

“Teacher, I have ridden one before, and it really can run very fast without exerting any effort.”

Xu Jianjun wanted to show it to them, but Professor An, who was in his early sixties, moved faster than him and took over the car to experience it.

Then he looked up and down, and directed the students to move in a 28-inch bicycle they had brought with them, as well as the materials and tools needed for modification, from outside the courtyard gate.

 Xu Yin: “…”

 The co-author has already been prepared.

 She kind of believed in this person’s identity, an academic talent who forgot about food and sleep! The kind where you can calm down and do research anytime, anywhere.

“Well, classmate Xu Yin, can we take apart your bicycle and take a look?”

"Can."

 The worst case scenario is to reassemble it according to the "scenario simulation".

“But it’s cold outside, why don’t you come to the main room.”

“No, no, the light outside is good, it’s nice here. You are busy with your business, don’t worry about us.”

"…" understood! This is like using her yard as a laboratory.

Fortunately, it hasn't snowed recently. There was some snow on the straw piles, and her mother had swept the ground clean. After a few days, it was dry enough to lie down on the ground.

 

But having said that, Xu Yin couldn't really ignore them. After explaining the situation to her parents, she boiled water and made a pot of **** tea. She took an unused small table in the kitchen and placed it under the eaves for them to drink at any time. Warm up some heat.

 However, even though the ready-made mold was right in front of them, Professor An and his apprentice still could not assemble the materials they brought.

 Everything else is fine, mainly because the so-called semiconductor board that can convert solar energy into electrical energy has never been successfully connected.

The semiconductors in Xu Yin's car were obviously much inferior to the ones they brought. They seemed to be removed from old radios. Why did hers work but the ones they found couldn't?

Seeing that it was time for dinner, Xu Yin invited them to eat at home: "My mother has already cooked. The food is getting cold very fast today. How about we eat first? And then we can do it after we finish?"

Xu Jianjun waved his hands hurriedly: "No, no, no, the teacher and professor will eat at our house. We agreed in the morning."

Xu Yin glanced at him: Then why don't you invite the people away and watch them struggle in such a cold weather?

Professor An put down his tools and shook his head with a smile, feeling ashamed in his heart.

He has been working in this field for decades in vain, and in the end he is no better than a high school senior.

Based on a blueprint, someone transformed an electric car that can run without plugging in.

  He led his team and pondered over it for several months, but still made no progress.

“It seems that I am really old! The waves behind the Yangtze River push the waves ahead. In the new era, it depends on you, the younger generation!”

 Xu Yin was ashamed: "I don't deserve the professor's praise. In fact, I was just messing around."

She just watched them assemble it. The steps were all correct. Why didn't it succeed? What exactly is wrong?

 “How about I give it a try?”

 Professor An is something that masters and disciples can only dream of.

Xu Yin went back to the house and changed into an old cotton-padded jacket, put on the sleeves, and squatted down to help them assemble it.

 After turning on the "scene simulation" function, every step and every component is like adding a slow motion or magnifying glass. Having practiced it countless times before, the operation is very natural and skillful.

Professor An and the other three were dumbfounded. Didn’t they just modify one? At this speed, no matter how you look at it, he looks like a skilled worker in the workshop!

 “I know the reason!”

Xu Yin clicked together the semiconductor boards and showed them to them.

“Your semiconductor materials are not only brand new, but also have very strong performance. The subsequent charge controller must be adjusted accordingly, otherwise it will not be able to operate.”

Professor An suddenly realized: "I understand! The designer of this drawing did not have very good semiconductor materials at hand. The data provided by the drawing was based on the materials he used at the time."

 In this way, classmate Xu Yin also got things wrong.

 Xu Yin nodded: "Yes."

 I thought to myself, OMG, a good thing almost turned into a bad thing!

 This drawing was modified based on the materials she had on hand, and the original design was still lying in her system warehouse.

 But the required materials were too high-end, and they were beyond the reach of a civilian high school student like her. Of course, you can only modify it with the materials you have at hand.

“So, if the charge controller is powerful and stable enough, it is also feasible to use better semiconductor materials?”

 Professor An looked at the modified bicycle thoughtfully.

"Does that mean that this set of designs is not only suitable for bicycle modification, but can even be used for..."

With his train of thought opened like this, the old professor’s eyes lit up: Ouch! There are so many areas where it can be used!

Xu Yin looked puzzled, pretending not to understand, and mentally giving a thumbs up to Professor An.

  Drawing inferences from one example, the new energy field is stable!
