Her mother's family has the money to engage in tidal flat farming, and Sister-in-law Xu is also a matter of concern.

Although it is said that the daughter who marries out spills the water, who doesn't want her mother's family to be good?

In the final analysis, this matter is a favor from the sister-in-law, and Sister-in-law Xu is grateful, taking advantage of the abundant ingredients at home in the first month, she changes her tricks to make for Xu Yin to eat.

Mother Xu stretched her face and muttered: "Use the things that my mother bought to please your sister-in-law, it's really good!" ”

Xu Yin heard it and couldn't laugh.

After Xu Zhinian finished this matter, he returned to the army. Wait for the approval of the army and the house to come down to pick up the wife and children, how can you wait for the beginning of spring.

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

"Yin Yin, this is the night school mechanics 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 intentions.

I knew there would be such a day, but I didn't expect it to be so soon.

She glanced at Xu Jianjun meaningfully.

Xu Jianjun was numb by her, and he was busy arching his hand: Auntie, I know it's wrong.

At first, he couldn't understand it horizontally and vertically, thinking that the county night school should teach this, so he went to register for a class, and after class, he asked the teacher as a student, and when he received the scholarship, he was also embarrassed, where did he think that this drawing was so important.

Professor An and the two came here mainly to see the solar-to-electric bicycle made by Xu Yin.

They followed the drawings and simulated more than a dozen times, none of which succeeded, and they couldn't help but wonder if Xu Jianjun's words contained water.

The principle illustrated in the drawings is indeed feasible.

After getting the drawings, the boss also sent someone to Xujia Village for an unannounced visit, and there was indeed a senior engineer who returned from overseas who lived in the cowshed.

From his background information, it can be seen that he did make relevant remarks during his years in the United States, but they were all unformed.

Maybe it's the result of research and development after arriving in Xujia Village?

It's a pity that the cowshed has been abandoned for many years, and even if the valuable information remains, it can't be found now, except for this drawing.

It was lucky enough for a little girl in the village to pick up a stone. It is said that he picked it up and turned it in, but it was returned as garbage.

After verification, the relevant personnel have been punished, but this drawing is honest, and even they professionals can't assemble it, the little girl really has the ability to do it?

She's just a high school student, right? He is also a high school student in a township with relatively poor educational resources.

They can't help but be suspicious.

Xu Yin sighed and pushed out the bicycles in the hall for them to see for themselves.

"Teacher, I've ridden it, and I really don't need to make any effort to run fast."

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

Then he looked up and down, and instructed the students to bring in a 28-bar bicycle they had brought and the materials and tools needed for modification from outside the courtyard gate.

Xu Yin: "......"

I've been prepared for a long time.

She kind of believes in the identity of this person, an academic talent who forgets to sleep and eat! The kind of person who can calm down and do research anytime and anywhere.

"That, Xu Yin, can we take your bicycle apart and take a look?"

"Yes."

It's a big deal to reassemble it according to the "scene simulation".

"It's cold outside, so why don't you come to the hall?"

"No, no, the outdoor light is good, it's good here. You're busy, leave us alone. ”

“……”

Got it! This is the requisition of her yard as a laboratory.

Thanks to the fact that there has been no snow recently, there is still some snow on the straw stack before, and the ground has long been swept clean by her mother, and after a few days, it is so dry that she can lie on the ground.

What's more, seeing that Xu Yin really has such a bicycle, Professor An's heart is surging and his blood is boiling, where can he still feel cold.

But having said that, Xu Yin couldn't really ignore them, and after explaining the situation to her parents, she boiled water and boiled a pot of ginger tea, brought a small table that was idle in the kitchen, and put it under the eaves, so that they could drink some warmth at any time.

However, Rao is ready-made mold was in front of him, and Professor An and his apprentices still failed to assemble the materials they brought.

Fortunately, the main thing is that the semiconductor board, which can convert solar energy into electricity, has never been successfully connected.

Obviously, the semiconductors on Xu Yin's car are much inferior to those they brought, and they seem to have been removed from the waste radio, why can she use it, but the ones they find can't play a role?

Seeing that it was time for dinner, Xu Yin invited them to eat at home: "My mother has already cooked the meal, and the food is cold fast this day, why don't we eat it first?" Do it after eating? ”

Xu Jianjun hurriedly waved his hand: "No, no, no, the teacher and professor eat at our house, and they will say okay in the morning." ”

Xu Yin glanced at him: Then you invited people away, on such a cold day, just watch them toss?

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

In vain, he has been in this field for decades, and in the end he is less than a high school junior.

With a drawing, someone transformed an electric car that could run without plugging in.

He led the team and pondered back and forth for months, but there was still no progress.

"It seems that I am really old! The back waves of the Yangtze River push the front waves, and the new era depends on your younger generation! ”

Xu Yin was embarrassed: "I don't deserve the professor's praise like this, in fact, I am also making trouble." ”

She just watched them assemble it, and the steps are all right, why didn't it succeed? What's the problem?

"Why don't I try?"

Professor Ann couldn't ask for it.

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

After turning on the "Scene Simulation" function, every step and every part is like adding slow motion and magnifying glass, and I have practiced countless times before, and the operation is naturally skillful.

Professor An and the three of them were dumbfounded, didn't they say that they would modify one? This speed, no matter how you look at it, looks like a workshop journeyman!

"I know why!"

Xu Yin clicked and spliced the semiconductor board and showed it to them.

"Your semiconductor materials are not only brand new, but also have strong performance, and the subsequent charge controller must be adjusted accordingly, otherwise it will not be able to drag it up."

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

In this way, Xu Yin is also crooked.

Xu Yin nodded: "Yes." ”

The heart said, oh my mother, a good thing turned into a bad thing!

The drawings had been modified by her with the materials she had at hand, and the original drawings were still lying in her system warehouse.

But the required materials were too advanced, which she could get from a civilian high school student. Of course, it can only be modified with the materials you can use.

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

Professor An looked at the modified bicycle thoughtfully.

"Does that mean that this design is not only suitable for bicycle modification, but can even be used for ......?"

As soon as the train of thought was opened, the old professor's eyes lit up: Huh! There are more areas that can be used!

Xu Yin looked puzzled, pretended not to understand, and gave Professor An a thumbs up in her heart.

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