Now that her parents have money to engage in tidal flat farming, Sister-in-law Xu has settled her worries.
Although it is said that a married daughter throws away water, but who doesn’t want her parents’ family to be well?
In the final analysis, it was my sister-in-law who helped me. Sister-in-law Xu was grateful and took advantage of the abundance of food at home during the first month of the year to cook it in various ways for Xu Yin to eat.
Xu's mother murmured with a long face: "Using the things I bought to please your sister-in-law, you are really promising!"
Xu Yin couldn't help laughing when she heard it.
After Xu Zhinian finished this matter, he returned to the army. I'll wait until the army gets approval and the house is ready before I can pick up my wife and children. No matter what, I have to wait until spring.
On the tenth day of the first lunar month, Xu Jianjun came to Lao Xu's house with two strangers.
"Yinyin, 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 hearing the introduction, Xu Yin understood their purpose.
I knew this day would come, but I didn't expect it to be so soon.
She glanced at Xu Jianjun meaningfully.
Xu Jianjun's scalp was numb when she saw him, and he 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 illustrated in the drawings are indeed feasible.
After getting the drawings, the superiors also sent people to Xujiacun for an unannounced visit. It was indeed true that a senior engineer who had returned from overseas had lived in the cowshed.
It can be seen from his background information that he did make relevant remarks during his years studying abroad, but they were all formless.
Maybe it was 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 what a little girl in the village picked up by good luck when she was picking 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's still just a high school student, right? And he is still a high school student in a rural middle school with relatively poor educational resources.
They couldn't help but doubt.
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 the car to experience it.
Then he looked up and down, and directed the students to move in a 28-inch bicycle they brought along with the materials and tools needed for modification from outside the courtyard.
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.
"Um, 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 hadn't snowed recently. There was still 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.
What's more, seeing that Xu Yin really has such a bicycle, Professor An's heart is surging and his blood is boiling, but he also feels cold.
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 ginger 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 failed to assemble the materials they brought.
Everything else was fine, except that the so-called semiconductor board that can convert solar energy into electrical energy could never be connected successfully.
Obviously the semiconductors in Xu Yin's car were of much inferior quality than the ones they brought. They seemed to be removed from used 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. The food is getting cold very fast today. How about we eat first? And then we can do it after eating?"
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 you should invite the people away, and just watch them struggle in such a cold weather?
Professor An put down his tools and shook his head with a smile, feeling ashamed inside.
It's in vain that he has been engaged in this field for decades, and in the end he is not as good as 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 can't believe that the professor praised me so much. In fact, I was just messing around."
She just watched them assemble it, and the steps were correct. Why didn't it succeed? What exactly is wrong?
"How about I give it a try?"
Professor An's master and apprentice couldn't ask for it.
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. Moreover, after practicing 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 why!"
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 hold up."
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 missed the mark.
Xu Yin nodded: "Yes."
I thought in my heart, oh my god, a good thing almost turned into a bad thing!
She had modified this drawing 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 she, as a civilian high school student, had no access to them. 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 design is not only suitable for bicycle modification, but can even be used for..."
As his train of thought unfolded, the old professor's eyes lit up: Ouch! There are so many areas where it can be used!
Xu Yin looked puzzled and pretended not to understand, mentally giving Professor An a thumbs up.
Drawing inferences from one example, the new energy field is stable!
