Now that her parents have money to engage in tidal flat farming, Sister-in-law Xu has finally 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 very grateful and took advantage of the abundance of food at home during the first month to cook various dishes for Xu Yin to eat.
Xu's mother muttered with a long face: "Using the things I bought to please your sister-in-law is really promising!"
Xu Yin heard this and couldn't help but laugh.
After Xu Zhinian finished this matter, he returned to the army. He would wait for the military approval and the house to come down to pick up his wife and children. He had 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 happen 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 shivered. 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 was left, it can't be found now, except for this drawing.
It was a lucky girl who picked it up while picking up rocks in the village. It is said that she turned it in after picking it up, but it was returned as garbage.
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 she is 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 originally 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 directed the students to bring a 28-inch large-bar bicycle, 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. He was an academic talent who forgot about food and sleep! The kind of person who could calm down and do research anytime and 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 outdoor light is good, it's nice here. You can do your business and don't worry about us."
"..."
Got it! This is 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.
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 a small table that was unused 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 is fine, except that the so-called semiconductor board that can convert solar energy into electrical energy has never been successfully connected.
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 prepared the meal. The food is getting cold very fast today. How about we eat first? We can finish it later?"
Xu Jianjun waved his hands hurriedly: "No, no, no, the teacher and the professor will eat at our house. It was agreed in the morning."
Xu Yin glanced at him: Then you should invite the people away, and just watch them tossing around 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 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 can't believe that the professor praised me so much. In fact, I was just messing around."
She had just watched them assemble it, and the steps were correct. Why didn't it succeed? What was the problem?
"How about I give it a try?"
Professor An, his master and his disciples, couldn’t ask for more.
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 it countless times before, it becomes very natural and skillful to operate.
Professor An and the other three were dumbfounded. Didn't they just modify one? At this speed, they looked like skilled workers in the workshop!
"I know why!"
Xu Yin clicked together the semiconductor boards and showed them to them.
"Your semiconductor material is not only brand new, but also has 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 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 modified this drawing based on the materials she had on hand, and the original design is still lying in her system warehouse.
But the required materials were too high-end for a civilian high school student like her to have access to. Of course, she could only use the materials at hand to modify them.
"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..."
The old professor's eyes lit up as his train of thought unfolded: Wow! 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!
