Chapter 29 Eight Zero Best Sister-in-Law (29)

  My natal family has money to engage in tidal flat farming, and Mrs. Xu has settled her mind.

  Although it is said that the married daughter splashes the water, but who doesn't want the mother's family to be good?

   In the final analysis, it was my sister-in-law who helped me. Aunt Xu was very grateful. Taking advantage of the abundance of food at home during the first month, she cooked it in different ways for Xu Yin to eat.

  Mother Xu murmured with a long face: "It's really good to please your sister-in-law with the things my mother bought!"

  Xu Yin couldn't help laughing when she heard it.

  Xu Zhinian returned to the army after finishing his work. Waiting for the military approval and the house to come down to pick up my wife and children, no matter how I have to wait until after the beginning of spring.

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

   "Yinyin, this is the evening 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 why they came.

  Knew such a day would come, but didn't expect it to be so soon.

  She gave Xu Jianjun a meaningful glance.

  Xu Jianjun's scalp was numb from her look, and he hurriedly cupped his hands: Auntie, I know I was wrong.

At the beginning, he couldn't understand it horizontally and vertically. He thought that the evening school in the county should teach this, so he enrolled in a class. After class, he pretended to be a student and asked the teacher. When he received the scholarship, he was stunned. Drawings are so important.

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

   According to the blueprint, they simulated more than a dozen times back and forth, but none of them succeeded. They couldn't help wondering whether Xu Jianjun's words contained water.

  The principle described in the drawing is indeed feasible.

  After getting the blueprints, the superiors also sent people to Xujia Village to make unannounced visits. Indeed, a senior engineer who returned from overseas once lived in the cowshed.

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

   Perhaps it was the result of research and development after arriving in Xujia Village?

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

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

   After verification, the relevant personnel have been punished, but the blueprint is honestly something that professionals like them can't assemble according to it. Is the little girl really capable of doing it?

  She's just a high school student, right? And he is still a high school student in a township middle school with relatively poor educational resources.

  They can't help but doubt.

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

   "Teacher, I have ridden before, and I can run fast without any effort."

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

  Then looked up and down, and directed the students to move in from outside the courtyard gate a bicycle with a 28-bar bicycle and the materials and tools needed for modification.

  Xu Yin: "..."

   The co-author has long been prepared.

  She has a little faith in this identity, an academic talent who forgets to eat and sleep! The kind that can calm down and do research anytime, anywhere.

   "Well, student Xu Yin, can we take your bicycle apart and have a look?"

"Can."

   The big deal is to reassemble it according to the "scene simulation".

   "But it's cold outside, why don't you come to the main room."

   "No, no, no, the outdoor light is good, and it's pretty good here. You are busy with your own, don't worry about us."

   "..."

understood! This is requisitioning her yard into a laboratory.

  Thanks to the fact that it hasn’t snowed recently, there was still some snow on the haystacks before, and the ground was swept clean by her mother long ago. After a few days, it was dry enough to lie on the spot.

   What's more, seeing Xu Yin really has such a bicycle, Professor An's heart is full of excitement and blood, and he doesn't feel cold.

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

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

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

   Obviously, the semiconductors in Xu Yin's car are much inferior to the ones they brought, and they seem to be dismantled from old radios. Why does hers work, but the ones they found can't work?

  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 getting cold quickly this day, why don't we eat first? Do it after eating?"

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

  Xu Yin glanced at him: Then you invited people away, watching them toss in such a cold day?

  Professor An put down the tool, shook his head with a smile, feeling ashamed.

   He has been engaged in this field for decades, but in the end he is not as good as a senior high school student.

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

  He took the team and thought about it for several months, but still made no progress.

   "It seems that I am really old! The waves behind the Yangtze River push forward the waves ahead, and the new era depends on you, the younger generation!"

  Xu Yin was ashamed: "The professor should not praise it so much, but I was just messing around."

  She watched them assemble it just now, the steps are all right, why didn't it work? What is the problem?

   "Why don't I try it?"

  Professor An's teacher and apprentice couldn't wish for it.

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

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

  Professor An and the three were stunned. Didn't they just modify one? This speed, no matter how you look at it, looks like a skilled worker in a workshop!

   "I know why!"

  Xu Yin spliced ​​the semiconductor board together with a click, and showed it to them.

   "Your semiconductor materials are not only brand new, but also have strong performance. The subsequent charge controller needs to be adjusted accordingly, otherwise it won't work."

  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 drawing was based on the materials he used at that time."

  Speaking of this, student Xu Yin has also hit the ground running.

  Xu Yin nodded: "Yes."

  I said in my heart, oh my god, a good thing almost turned into a bad thing!

   This drawing was modified by her based on the existing materials at hand, and the original design drawing is still lying in her system warehouse.

  But the required materials are too advanced, and she, an ordinary high school student, can't get it. Of course, it can only be modified with materials that are available 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 soon as he opened his mind, the old professor's eyes lit up: hey! There are many fields that can be used!

  Xu Yin showed doubts on her face, pretending not to understand, and gave Professor An a thumbs up in her heart.

   Infer other cases from one instance, the field of new energy is stable!
