60s researcher

After Professor Xie left, Lu Jian took out all the things that were put in the cabinet at noon, and searched carefully on the bed, but he still couldn't find anything after searching for a long time.

Sitting on the bed, he thought of the sack for stuffing things, he wouldn't believe it was still inside, but he saw that the sack was too dirty, so he took it out and threw it away at noon.

Thinking of this, Lu Jian ran out quickly, without even closing the door, and ran all the way to the garbage dump next to the dormitory building.Fortunately, the garbage here is always taken out in the morning, and the residents are all researchers, so no one will ask for a sack.When Lu saw it, the bag was still lying on the ground.

Lu Jian rushed over to pick up the bag, and sure enough, he saw a letter inside with his name written on it.

Lu Jian picked up the letter, thought for a while, and picked up the sack again. It was a bit dirty, but after washing it, it could still be used, and then it could be used to send things home.

I didn't even think about it when I threw it away. If Lu's mother knew about it, he would definitely say that he wasted things.

As soon as he returned to the dormitory, Lu Jian opened the letter. The words should be written by Qin Hui, but the tone of the words inside was Lu's mother's.

The letter was very long, with a lot of miscellaneous words, and Lu's mother first complained about Lu Jian, blaming him for not knowing to return home news after he had been away for so long, which made her worry all the time.Then I asked him a lot if he was doing well here, if he didn't have rice to eat, if he could get used to it, if it was cold, if he was being bullied, etc.

Seeing this, Lu Jian unconsciously smiled, feeling warm in his heart. Mother Lu should be the person who cares about him the most in the world. She considers everything for him, so sometimes he doesn't care too much. He has the ability , brother is not ungrateful, so why bother so much.

Lu Jian's idea is that I treat you well, so please treat my parents well.In fact, he didn't come here for a long time, and he didn't get along with his brothers and sisters at home for a long time.Everything he did was because of Lu's father and Lu's mother, they were really kind to him.

Withdrawing his thoughts, Lu Jian continued to read, and what he wrote were all things that happened at home. The sugar factory had already started work, the elder brother and the second brother both went in to work as workers, and the elder sister-in-law and second sister-in-law felt very good recently.The primary school in the team also started, and the two naughty boys were sent in. Mother Lu said that they studied well and were as smart as him.

The rest of the conversation was all about praising the two kids for their good grades, so Lu Jian watched patiently.In the end, Mother Lu mentioned the elder sister's marriage again, and asked Lu Jian to send letters to her family frequently.

Lu Jian put the letter away after reading it.Thinking that he still had to write a letter back, he tore off two pieces of paper from his notebook and started writing.

"Mother, I'm sorry, I forgot to report my safety after I came here, which made you worry. I'm fine here, and the cotton jacket has been received, and it fits well. Rice is abundant here, and I'm used to eating it. The craftsmanship of the canteen master is very good, and it's okay. Order..."

"I will go to Province G in December, and I should be able to go home by the way..."

"Elder brother and second brother already have jobs, you can enjoy your life with peace of mind in the future, don't worry about it..."

Lu Jian finally wrote down the words "I will often write letters back", then covered the pen, and waited for the handwriting to dry slowly.

The post office is closed now, so I can only wait until noon tomorrow to buy stamps and send the letter.

Early the next morning, Lu Jian folded the letter on the table and put it in his pocket, then went to the laboratory.The demonstration meeting started in the morning, and Researcher Liu asked Lu Jian to go in with him. He had to make preparations in advance and check the drawings.

Today's demonstration meeting was not held solely for Lu Jian's team. At present, several teams have prepared design drawings, and there are several plans that need to be demonstrated.

Because it is a modification of the 130 drilling rig, the current design is almost based on the improvement of all structures. This demonstration is the feasibility and applicability of the drawings.

Not only officials from the Ministry of Petroleum, but also old researchers who have participated in the design of the 130 drilling rig and technicians from the Mechanical Engineering Department will come to participate in this demonstration. They will stay here for about a week and conduct demonstrations on all sub-projects one by one. .

So all the drawings must come out within a week or so at the latest.

Lu Jian's project was ranked third, with Researcher Liu as the main speaker and Lu Jian as an assistant.

Because it was the third one, Lu saw that they didn't go there early to wait, and they were very close, so Researcher Liu directly arranged for someone to watch them, and called them down when the time was almost up.

The two of them carefully calculated the data on the drawing in the office, and after confirming that there was no problem again, they discussed all possible problems.At about 9:15, they were notified to go down. The second group had been in for [-] minutes, and they should have arrived soon.

The two quickly packed up the materials and went to the small meeting room on the fourth floor. There were several groups of people waiting outside the meeting room, and they should have been waiting here for a long time.

Lu saw that they didn't have to wait long. After about 10 minutes, the second group came out, but they seemed a little frustrated, and they should have been dismissed.

After the people left, a person who should be the secretary asked Lu to see them go in.

Lu Jian quickly followed Researcher Liu in. As soon as he entered the conference room, there was a blackboard hanging there, and a podium was under the blackboard.In the middle of the meeting room is a circular table. There are several people sitting on both sides of the table. It seems that they are still discussing the last project. They stopped when Lu saw them come in.

"Hydraulic pump project team, right? Let's start." The person sitting facing the blackboard has gray hair and a thin face. Even if he is sitting there, he seems to be much taller than others, and his eyes are sharp, making him look inaccessible.

"Okay." Researcher Liu quickly responded, and hung a drawing on the blackboard.

Lu Jian quickly walked over to the table, and put a detailed drawing on everyone's table, which attracted everyone's surprised eyes.Before, no one would take the time to sit on this matter. They all looked at the blackboard and listened to people's lectures. When people are old, their eyesight is not good, and it is really difficult to see. All of a sudden, several researchers have a good impression of him.

In fact, Lu Jian didn't do anything special. In the future, there will be printers and copiers, and everyone will have a copy of the documents when discussing issues in meetings. Although there is no printer here, Lu Jian still did the same preparations as he did before, and drew some drawings. He was already good at drawing, and he was not very familiar with this design, so it didn't take long.

When Lu Jian returned to the edge of the podium, Researcher Liu on the podium began to explain the design of his project team, holding a bamboo ruler in his hand to point and click on the drawings on the blackboard.

Everyone in the audience listened carefully, looking at the drawings in their hands and the blackboard from time to time.

Researcher Liu finished speaking in about 20 minutes. He put down the bamboo ruler and waited for everyone to ask questions.

"Your design directly overturns the previous vane pump and adopts the structure of a plunger pump, but this structure is very complicated, with high requirements for materials and precision. How can you ensure that this requirement can be met?" Sitting in the middle The most important questions were asked directly.

"Our structure has already been simulated and tested..." Researcher Liu and Lu Jian knew that this question would be raised and were well prepared.

"As for the accuracy of the material, we have already designed several parameters, and we can continue to experiment later..."

After listening to Researcher Liu's words, the man nodded in satisfaction and didn't say anything more. Then several people asked different questions, and Researcher Liu answered them with ease.

"I don't have anything to ask about this design, but the cost?" The person who asked the question was an official from the Ministry of Petroleum, who was more concerned about the cost issue because there was a special person in charge of technical issues.

"This cost will be more expensive, but it can adapt to work under high pressure, and the power of the hydraulic system will also be greatly improved."

"There is another question. According to what you said, this design should also have a high requirement for the cleanliness of the oil? But we can't provide oil with such a high cleanliness now. How can the machine operate without oil? Even if it is barely used Yes, the machine is prone to failure, right?"

As soon as this question was raised, Researcher Liu was a little dumbfounded. He really hadn't thought about it, and couldn't answer it for a while, so he unconsciously glanced at Lu Jian.

"Leaders, our project team has come up with a cleaning and purification method for this problem. This formula is..."

Lu Jian didn't think about this aspect before, but there are already many purification methods in the 21st century, and cleanliness is no longer a problem. He hurriedly walked up to the podium, picked up a piece of chalk, began to write, and then began to explain in detail.

After Lu Jian finished speaking, the people in the audience began to discuss with each other, but there was no result for a long time.

"Okay, the design of this project has been approved." The two waited for a long time before the discussion ended, and the leader informed the result.

"This little comrade is also quite insightful in chemistry. You came up with this formula yourself, right?" After he finished speaking, another person said something and looked at Lu Jian with a smile in his eyes.

"Yes, we haven't researched it before, he came up with it himself." Before Lu Jian could speak, Researcher Liu quickly responded.

"..."

Lu Jian didn't know how to answer, this formula really didn't exist now, but he really didn't invent it.

"Then this should also be applied to oil purification, right?"

"This needs to be tested." Lu Jian replied very cautiously. Today he has already been in the limelight, and he has never been in contact with oil before, so he probably doesn't know.

"Okay, what's your name? Which student are you from?" the man asked again.

"My name is Lu Jian, and I'm a student of Professor Xie of Hu'an University of Science and Technology."

"Okay, you guys go out!" That person wanted to continue asking, but was interrupted by the person above. After all, it was still a demonstration meeting, and there were still many projects to come, so time was tight.

Lu Jian quickly followed Researcher Liu out. When the two came out, there was a thin layer of sweat on their foreheads. Because there were many people outside, they didn't speak, and quickly returned to the project team.

Because the results came out today, everyone was there. When Researcher Liu was about to arrive at the laboratory, the tension was gone, and only joy was left. When he entered the door, his face was full of smiles, and he told everyone clearly about the project. already passed.

But still no one made a sound, they were all waiting for Researcher Liu to announce and give an accurate answer.

"Our blueprint has passed." Researcher Liu said loudly, bursts of cheers erupted from inside, and a total of more than ten people showed an unusual momentum.

Among the dozen or so people, only three or two participated in the meeting on the first day, and the rest were transferred later. At first, Lu Jian thought that there were only a dozen people in the entire hydraulic team, but later he found out that the few who could attend were the least Those with mid-level professional titles, Lu saw that he got in through connections.

"Okay, the task ahead is still very heavy. This is just the first step. Hurry up and work. I will celebrate everyone after the project is completely over." Researcher Liu interrupted them quickly. The most important. k

"Yes." After hearing his words, everyone became quiet, and then went to their positions to start working, all of them seemed full of energy.

Researcher Liu saw that they had all started working, so he went to his office with Lu Jian.

"It's really thanks to you today, otherwise I really don't know what to do." Researcher Liu looked a little scared.

"No, I didn't think about this issue before, this time it was a mistake." Lu Jian felt that he didn't think about it this time, and he didn't think about the oil issue at all.

"I really didn't expect you to be so talented in chemistry." After all, after passing the argument, Researcher Liu seemed very happy.

"It's really not. I just discovered it suddenly when I was doing research on machine tool lubricants. It's really a coincidence." Lu Jian shook his head quickly. His chemical knowledge was learned in high school.

"After all, you don't do chemical research. It's great to be able to discover this by accident. But we are studying mechanics, so it's better to focus on mechanical research in the future." Researcher Liu thinks that Lu Jian is so talented in mechanics, so he will do it in the future. You should concentrate on doing mechanical research, and don't be hooked by some chemistry.

"Got it." Lu Jian nodded quickly.

"By the way, Team Leader Liu, I will take a period of leave in December." Lu Jian remembered that he was going to attend the Canton Fair.

"for how long?"

"Probably about twelve days." Lu Jian thought that it would take about six days to go back and forth, and the visit time of the Canton Fair is three days, so he may have to check the venue two days in advance.

"So long?" Researcher Liu felt a little unhappy. December was the busiest time for them, and the whole research had entered the most important stage. Ten days was half a month.

"Do you have to go?" Researcher Liu has always felt that Lu Jian is his right-hand man and can give him good advice on many things.

"Group Leader Liu, the air conditioner I developed before is going to participate in the Canton Fair, and the factory will definitely let me go." Lu Jian shook his head helplessly. He didn't want to participate in this kind of occasion, but he is still a member of the bicycle factory, and this is also his the results.

"Air conditioner? I heard that they can't get it in S City now?" He was a little surprised when he heard this, but he didn't expect that it was actually researched by Lu Jian.

"I don't know about that. I haven't gone out since I came here." Lu Jian really didn't know how the air conditioner was bought now.

"It's a good thing, but there are few places where it can be used. I heard that buying an air conditioner requires a certificate from the power plant. You need to check the line first. It is not allowed to be used in places that are too old, and the number of units used in a region is also limited. A power plant The certificates are going crazy.” Researcher Liu said this very emotionally. Now that he has money and tickets, he can’t buy it. If he dares to start, he doesn’t need a certificate. The lines have all jumped, and it is mandatory to issue a certificate before buying an air conditioner.

"..."

Although Lu Jian had expected that there would be a problem with the circuit, he did not expect the solution to be so...

He didn't know how to describe it, so now it depends on who is quick besides the ticket.

"Okay, you go. Fool a few more foreigners, let them buy more air conditioners, and we can get more foreign exchange." Researcher Liu laughed, his eyes were full of light, as if a lot of foreign exchange had flown like him. over here.

"Yes." Lu Jian didn't refuse, at worst, he also acted as a salesman, using a few sales techniques written in later books.

"It will take a long time for you to go. We will try our best to get the prototype out before you leave, and it will take a long time to test the performance of the prototype afterwards. We can just stagger the time." Researcher Liu thought for a while, and decided to Work overtime to catch up with the progress.

"Okay, Team Leader Liu." Lu Jian nodded. He also wanted to finish this project as soon as possible. The hydraulic transmission system is widely used, not only for drilling rigs, but also for various mechanical equipment such as machine tools. It is very important .

"Now that the drawing has been determined, the next step is to realize it. Our current design structure is very complicated, and the precision of the components is also very high. The fault tolerance rate is extremely small, and the task is very difficult. Two pairs of precision parts must be made as soon as possible. come out."

"I have determined a few values, and I can start the experiment tomorrow, but these parts." Lu Jian knew the exact data, but one success was too amazing. He mixed the correct values ​​into it, and it succeeded almost a few times .What matters is whether the production process can meet the requirements.

"I'll take you to the Huangshi factory tomorrow. The 130 drilling machine is produced there. The equipment is complete. Give the drawings over there. There are many eighth-level workers over there. They can definitely get what you want. "Researcher Liu seems very confident. These eighth-level workers are more powerful than machine tools. These hands have achieved countless major projects.

"Okay." Lu Jian saw that the matter was almost discussed, so he left and went to Huangshi Factory tomorrow. There are still many things to prepare.

At noon, after eating, Lu Jian ran to the post office to buy a stamp to send the letter.

When he entered, there was only one person on duty. He knocked on the counter and asked for a four-cent stamp. Out of the corner of his eye, he happened to glance at a stamp album. In the middle of it was a set of Mei Lanfang issued in 1962. Toothless tickets, denominations from four cents to five cents.
