60s researcher

"I have seen the air conditioner you have developed before, and I feel that there is still room for improvement in terms of noise reduction. Take a look at this valve system..." Liang Maoxue was very excited when he mentioned what he was good at. With high spirits, he ran to the table, picked up a pen and paper, and began to draw the structure diagram.

"Then do you have any way to solve it?" Lu Jian didn't expect that he was really right. These problems are also what he wants to improve with the third generation air conditioner.

"First of all, it is necessary to reduce the impact speed of the valve plate against the valve seat. You can choose a softer valve seat material, and adjust the shape of the valve port..."

"Then do you have anything you want to study?"

"When I graduated in 59, I heard that there was already a 914-type electrostatic copier with relatively complete performance in foreign countries. I have been studying this privately since then. I found that they have always used selenium as a photoconductor, but I found that photophoresis can color imaged, if we..."

"Do you have a complete plan?"

"I have a lot of ideas one after another, but I haven't tried it, and I don't have a complete plan yet."

"You haven't mentioned it to Mr. Huang." Lu Jian doesn't know much about copiers. The copier industry in the 21st century has been well developed and fully functional.

"Brother, he wants me to stay in the shipyard." Liang Maoxue was dejected.

"Of course I welcome you if you want to go to the electrical appliance factory, but you still have to have a good chat with Huang Gong. I don't think he is unreasonable." Lu Jian thinks that he has great ideas and is willing to persist. We will study together in the future, of course. It's a good thing, but he has a wife and son here, and there are a lot of entanglements, so Huang Gong is still willing to let him go.

"And your wife and family, you can't run away alone, right?"

"I see, I will arrange things well." Liang Maoxue raised his head and seemed to have made up his mind.

After Liang Maoxue left, Lu Jian began to write a letter, which was to be sent back. He thought he would be able to go back soon, but he didn't expect it would be delayed for a while, and he didn't know what was going on at home.

"Impossible, you lied to me." In the silent night, the man's voice seemed a little desperate.

"What are you lying to, you are looking for the married Lu Fenfen, she is not the real child of the Lu family." Yang Zhen shook off his hand, smiling very proudly.

"The Lu sisters are twins."

"How do you know that you are not meeting twins?" Yang Zhen looked at her wrist, it was already red.

"The personalities are completely different." Qi Changzheng carefully recalled the twin sisters he met at Lu's house before, only remembering their lowered heads and weak voices.

"Forget it if you don't believe me, I'm not looking for someone anyway." Yang Zhen turned around and planned to leave.

"Wait, how are you sure it's Lu Fenfen and not Lu Fangfang?"

"There is a scar on the inside of her wrist, have you forgotten? It was reserved for you, and Lu Fangfang doesn't have one on her hand." Yang Zhen turned her head and smiled casually.

"Oh, I hope you're telling the truth, otherwise..." After finishing speaking, he lifted his foot and left.

"Damn the male lead, you actually made me suffer so much. Let me see what you do next." Seeing the man walk away, a smile appeared on the corner of the woman's mouth.

Lu Jian covered his aching forehead and struggled to get up from the bed. Ever since the heroine appeared, he would flash some pictures from time to time.

And what the system said, he is the real Lu Jian of this era, but he was brought back by the heroine in reverse time, this can't be true, can it?But he does have memories of his previous life, and he is sure that he is not Lu Jian, but he often dreams about the heroine.And the heroine wouldn't really say that her eldest sister is the person the hero is looking for?

Lu Jian packed up his food and went to the research institute building, and went directly to Huang Gong's. There were already many people inside.

"Gong Lu here."

When Lu Jian heard the voice, he saw Liang Maoxue. He was sitting with the other party yesterday. There were several books on the table in front of him. Lu Jian walked over and sat down. The model he used yesterday was still there.

"It's pretty early." Lu Jian picked up the model and continued to look at it.

"Yes, it's all like this." Liang Maoxue continued to read with a book, and there was a notebook beside him, and he took notes while reading.

"See Lu, here you are. Here are the blueprints. Team Leader Ma and the others rushed them out overnight. Some data has been changed. Please take a look." Suddenly Huang Gong ran in with a blueprint in his hand.

"Okay." Lu Jian put down the things in his hands, took over the drawings and looked at them carefully.

"Huang Gong, according to the above data, the design of our door also needs to be changed. These distances need to be recalculated, and the pitch changed by the pitch changing mechanism must also be carefully calculated. The blade must be stable at the required pitch propeller position. .

"Well, it will take some time, so it's not a big problem." This Huang worker is not worried, they have done it several times before.

"I've seen the place yesterday. These two parts can be slightly moved to this side. The distance should be..." Lu Jian took a pen and wrote down two data on the drawing.

"Let's experiment later." Huang Gong looked at the model for a while, then nodded.

"Now the sensitivity of the important feedback device, our previous feedback device was always a bit off. You can see that when the piston moves to the left, the response of the signal rod is always one step behind, and the output feedback signal will give the wrong pitch." Huang Huang The worker raised another question.

"Adjust it in this position, and this material..."

"I'll try it right away. Is there a hydraulic control check valve in this oil circuit to improve the lock function?"

"Yes, it's better to add one." Lu Jian nodded.

"I'm sorry, Lu Gong. Luo Gong was in charge of this area before. He suddenly entered the hospital. I haven't been going well." Huang Gong looked very happy, called a group of people, and left, saying that he was going to the big laboratory. Experiment inside.

"Lu Gong, did you go back after finishing this piece?" Liang Maoxue, who was reading a book, touched Lu Jian with his hand.

"That's for sure. I came here mainly to do the hydraulic transmission system. Now that this part has been completed, there are still many things to do in the electrical factory? Your ship project is not so fast."

"Is that so?"

"Liang Gong, do you have to leave here?" Lu Jian felt that even if he wanted to do other research, he didn't need to go so far.

"Gong Lu, I live too comfortably. I've been under the wings of others. I have no assertiveness or ideas."

"Well, you should discuss it with your family first, and then contact me when you are sure." Lu Jian felt that the possibility of him going to Hu'an City was too small. Liang Maoxue's character was a bit soft and his will was not firm, otherwise, how could he be harmed by others? Unconsciously hurt many times.

"By the way, what happened to the book I let you read?" Lu Jian decided to change the subject, after all, it was a private matter.

"There are a few places I don't understand..."

In the next few days, Lu Jian would often follow them to the big experiment to help. After recalculating the data, the project progressed very quickly. From time to time, Lu Jian would come up with a small idea. Ten days later, the prototype of the propeller was also manufactured, and the underwater experiment began. test.

After a week of experiments, the variable pitch propeller can improve the maneuverability and maneuverability of the ship, and can improve the service life of the main engine and stern tube bearings.

After finishing this work, Lu Jian applied to Team Leader Ma. He was going to go back to the electrical appliance factory, and Team Leader Ma also agreed. They still have the next stage of tasks.But Liang Maoxue didn't come to see him until Lu Jian set off to return to Hu'an, and he followed Huang Gong for the next few days.Lu Jian didn't care, he packed his things and was ready to go back.

When he left, Liang Maoxue drove him off, and the two of them didn't speak a word along the way.

"Lu Gong, I talked to Huang Gong, and I have already applied to be transferred to the city's machinery factory, and I will work there after that." When he was about to get off the car, he suddenly stopped Lu Jian.

"That's pretty good, I'll go first." Lu Jian thinks this is not bad, it's similar to what he thought, so that he can take care of the family and do what he likes.

"Gong Lu, I will research the latest copier soon." Seeing him walk away, Liang Maoxue shouted.

Lu Jian didn't stop, he rushed back and waved his hands and got into the car directly.

The train stopped in N City halfway, and it seemed that many people got on the train, and the people who lived opposite Lu Jian went out, and the door was not closed.

"Lu Gong?" Lu Jian was sitting in the car reading a book when suddenly a voice stopped him.

"Liu Gong?" Lu Jian was very surprised to see the person in front of him. The one standing at the door was actually Liu Gong from the L Provincial Research Institute. Didn't he work on a project with Professor Xie and the others?

"What a coincidence, Professor Xie and the others are right in front." He saw Lu Jian very happy.

"I'll go and have a look." Lu Jian stood up and followed him to Professor Xie's box.

Before Lu Jian got closer, he heard the sound of arguing in the carriage. At first he thought it was because of another sentence, but when he got closer, he heard it was because of playing chess.

"Wait, I don't want to go down here, change to this place." It was Professor Xie's voice.

"Luozi Wuhui doesn't know, no, it can't be changed, you stop and put it down." This should be Professor Xia, who looks distraught.

"Just play here, keep coming!" Professor Xie should have successfully changed the game, with a little complacency in his tone.

"Humph."

"Who do you think this is?" Liu Gong opened the door and led Lu Jian in.

As soon as Lu Jian entered, he saw Professor Xie and Professor Xia sitting opposite each other playing chess. Seeing someone coming in, Professor Xia immediately shuffled the chess pieces and stood up.

"Someone is coming, no more, no more."

"Lu Jian, it's you!" Professor Xie ignored his small movements, saw Lu Jian at a glance, stood up, and came over to pull Lu Jian to sit beside him.

"So it's Lu Jian, you came from the shipyard in D Province?" Professor Xia took a step to see Lu Jian, and was a little surprised.

"I went to get a glass of water just now, and Lu Gong's door was open, so I saw it. Otherwise, I might not meet him when I got off the bus." Liu Gong sat next to Professor Xia with a glass of water.

"Teacher, Professor Xia, I just finished working in the shipyard and now I'm going back to Hu'an City, how about you?" Lu Jian really didn't expect such a coincidence.

"I went to S City, your teacher and Professor Xia went with you, and also went to Hu'an City, so you can take care of them both." Before they could speak, Liu Gong said it first.

"Is the project over?"

"En." Professor Xie nodded without saying anything, and Lu Jian didn't dare to ask more.

"Lu Jian, let me ask you, did Jian Mingyuan really adopt two children?" Before Lu Jian and Professor Xie said a word, Professor Xia couldn't help but speak, and everyone's eyes were on him for a while. Staring at Lu Jian, his eyes were full of curiosity and disbelief.

"It's true, it's been more than half a year since the adoption, and the household registration is under Jian Gong's name." Lu Jian nodded.

"Hey, this kid didn't lie to me, and he has both sons and daughters all of a sudden." Hearing Lu Jian's affirmative answer, Professor Xia was very happy, and his whole face was into a ball of laughter.

"Don't get too excited, maybe it's just a superficial trick to trick you, old man." Professor Xie poured cold water on him abruptly.

"Oh, with Jian Mingyuan's personality, it's strange that he is willing to lie to me." Professor Xia didn't panic at all. He didn't believe that a person who directly said that you were too long-winded would take the time to lie to others.

"Teacher, Jian Gong has changed a lot now. He is very kind to the two children. He misses bringing them food and clothing every day. You will know when you go back." Lu Jian hurriedly interjected, fearing that they would quarrel again.

"Old man Xia, did you hear that, if Jian Mingyuan is really that good to the kid you just met, you have to think about it, he only gave you a letter in three months, can this student accept it?" Thank you The professor's words made Professor Xia's foot hurt again.

"Then your student didn't even write you a letter." Professor Xia was not to be outdone.

"..." Lu Jian, who was suddenly involved, was extremely innocent. He didn't even have any news about Professor Xia, so there was no way he could write a letter.

"Can this be the same? My students don't know where I am?"

"What's the difference? Aren't they all students, working in the same place? I didn't even ask."

Lu Jian really didn't dare to ask.

"Two professors, stop arguing, or continue playing chess?" Liu Gong was also afraid that the two of them would quarrel, so he quickly changed the subject.

"Whoever wants to play with this stinky chess basket will always regret it." Professor Xia snorted coldly.

"Forget it, Lu Jian, you and I will play." After finishing speaking, Professor Xie set up the chessboard on the table, motioning Professor Xia to get out of the way and give up the position to Lu Jian.

Professor Xia moved to the side, and Liu Gong quickly stood up and got out of his seat. After Lu Jian was opposite to Professor Xie, he sat next to Professor Xie.

"Teacher, I don't know how to play chess." Lu Jian had never played chess before, nor had he played Go, at most he had played backgammon, and he didn't even know the rules.

"It's okay, I'll teach you." Professor Xia moved closer.

"I don't need you to teach me, I will do it myself." Professor Xie began to introduce the rules without waiting for Professor Xia to speak.

Just like that, Lu Jian started playing chess without knowing a thing. Professor Xia, who said he could be a military adviser, seemed to be not very good. Professor Xie, who was opposite, said from time to time that the chess pieces accidentally fell into the wrong position. Laipi, he is really tired.
