60s researcher

Zhao Lei became anxious, "You mean the reason why my sister is like this is because we don't care too much about her now?"

Lu Jian sat up, "Of course, your sister is still a little girl who wants to cry for candy. You all think she has grown up, but she is not."

"Thank you, good brother, I'll go back first." Zhao Lei stood up and patted Lu Jian on the shoulder, then hurriedly opened the door and ran out.

Lu Jian closed the door with a smile, went back and lay down on the bed again, and slowly fell asleep.

Time passed by, Zhao Lei didn't know what happened after he went back that day, and he didn't talk to Lu about it, but he seemed to be in a better mood, and he would go to the supply and marketing agency to find Zhao Duoduo every three or two days, and the relationship was better than before. It's much better, but I just don't know what's going on with that subject.

However, time was too tight, so Lu Jian put it down in a blink of an eye.

One day when Lu saw them busy in the laboratory, Zhao Lei ran in suddenly, looking flustered.

Lu Jian: "What are you running? What happened?"

Zhao Lei said anxiously: "The southern chief of the mechanical engineering department brought people to inspect, and he is on the second floor now, and he should be coming up soon." He has been collecting data in the large laboratory on the first floor recently, and suddenly there are so many People surprised him too, but Nanchang didn't stay on the first floor for too long, and then went to the second floor, and he took the opportunity to run back.

Hearing his words, everyone in the laboratory became a little nervous, and looked a little flustered, especially those young researchers, who didn't know whether to tidy up the laboratory first, or pretend to concentrate on the experiment.

Lu Jian wasn't too worried, "Come here as soon as you come, you just continue to do the experiment as before."

Zhou Changming also smiled and comforted him: "Continue to do your own thing, and just tell the truth when you are called."

Seeing that the two leaders were very calm, the researchers in the group felt relieved and continued to concentrate on their own work.

Lu Jian glanced at Lu Jian, who was resting on the chair, and kicked the foot of the chair, "We already know the news, you can go back to the first floor to collect data, remember not to make any mistakes. "

Zhao Lei rolled his eyes at him, and murmured softly, "Throw it away when you're done using it, I'm lucky I came back so quickly."

Seeing that he didn't hear clearly, Lu asked with some doubts, "Where are you muttering?"

Zhao Lei immediately stood up, and while running outside, said: "I didn't say anything, I went down first." Zhao Lei disappeared outside the door in two or three steps, Lu Jian shook his head, it's been so long, Zhao Lei is still like this.

Although Zhao Lei said that Chief Nan and the others would be arriving soon, it was already past eleven o'clock when they arrived at Lu Jian's laboratory.

Lu Jian heard a group of people coming from a long distance away, Lan Mingda pulled Lu Jian for a while, put down what he was doing, and went out to meet him. Just as he was at the door, he saw the head of the South leading a group of people coming, followed by Director Wu, Zhou Changming, and two middle-aged men wearing glasses.

The head of the South saw that Lu was very happy to see them, he stretched out his hand and shook them quickly, "Lu Gong, Lan Gong, we haven't seen each other for a long time."

Lu Jian also stretched out his hand and held it back with a smile on his face, "Master Nan, you are very welcome to come and inspect."

Lan Mingda: "Master Nan, welcome, welcome."

The Minister of the South looked very happy, probably because he was very satisfied with the results of the previous inspection, "Lu Gong, I heard that your numerical control device is progressing very well, and a chip with 4000 transistors has been produced. How about it? Let me See the finished product?"

"Of course." Lu Jian led them into the laboratory. Although their laboratory is not as big as the first floor, it is not small. Now the chip production has been moved to the innermost part. Lu Jian took them inside. go.

Eight or nine people are busy over there. There are many chip processes, and almost everyone is responsible for one of the processes. They are still trying to generate more transistors, and the design of the circuit diagram has to be modified according to different requirements.

Because Lu Jian said before, even if so many people came, they were all busy.

Lu Jian took out the newly produced No. 4004 chip and put it in the hands of Nanchang Chang, "Nanfang Chang, our current second-generation chip uses photolithography technology, uses optical lenses to reduce the circuit diagram, and engraves it on the wafer. after……"

"The use of large-scale integrated circuits can greatly reduce cost and power consumption, and will improve the comprehensive utilization of power and spectrum. The most important point is that the volume and weight will be greatly reduced, which will make it more convenient to use. In terms of transportation... "

"The chips we produce are for data transmission, calculation, and control..."

In the next ten minutes or so, Lu Jian was there to explain, and Zhou Changming helped to add. A group of people listened very carefully and didn't mean to interrupt.

"We have completed the point system now, and after a period of time, we will design various control and calculation programs, which are expected to be completed within four months, and the design of the memory and arithmetic unit will be completed in the next half a year... "

After Lu Jian talked about the arrangement of the whole project, he stopped and looked at Mr. Nan.

Nanchang looked at the small chip in his hand, but he still couldn't imagine that there were so many circuits on it, and he was full of surprise.

The two people next to him couldn't help it after hearing what Lu Jian had said for so long, and one of them suddenly said: "Mr. Nanfang, we are very interested in this chip. Could you let us have a look?" He The words are polite, but there is some momentum that is inevitable.

Nan Chang seemed to think of them just now, and said embarrassedly: "Of course, of course." After speaking, he handed them the chip in his hand.

"I'm very sorry, I'm so happy that I actually forgot about you two."

Those two didn't seem to mind much.

Then the Minister of the South hurriedly said to Lu Jian and Lan Mingda: "Lu Gong, Lan Gong, these two are Professor Gu and Professor Shang of the Capital Institute of Computer Technology, and they presided over the previous transistor computer research."

It turned out to be them. This is the ancestor of Huaguo's computer technology research. Lu Jian was very excited and greeted him very enthusiastically, "Professor Gu and Professor Shang are welcome. You are very welcome to visit here. I am Lu Jian."

"En." The two professors concentrated on studying the chip in their hands, and replied to Lu Jian very coldly, without even looking in.

The atmosphere was a bit awkward for a while, and the head of the south quickly said to Lu Jian, "They, they forgot where your chip was when they saw it. Don't worry about it. Let's continue talking about the project."

Lu Jian didn't care too much, knowing that they were just thankful for the chip, he still smiled and said to the Minister of the South: "Okay."

"Gong Lu, what they are making now is the second-generation chip of Longchuang, right? Is the process very complicated? Will there be any difficulties?" Director Nan looked at the researcher who was concentrating on his work.

Lu Jian pointed to one of the people who were processing the wafer and said: "There are still many difficulties, just like this wafer, the thickness of the slice will always have errors, and the polishing of this silicon wafer is very demanding. The current machine The accuracy is not enough..."

Then he pointed to a researcher who was etching circuit diagrams and said: "The optical lens we use now has insufficient magnification, otherwise we can continue to produce more transistor chips."

"..." Lu Jian was not polite, and directly explained some of the difficulties he had encountered so far, most of which were related to hardware equipment.

Director Wu and Zhou Changming on one side both felt that Lu Jian was really courageous. So many people asked so many questions in front of them. What if the director of the South felt that he was forcing the higher-ups to solve the problem?More importantly, what if the Minister of the South can't solve it?Isn't this embarrassing?Although they were anxious, they did not dare to express it directly.

The situation they were worried about did not appear. The Minister of the South had been listening carefully to what Lu Jian said, frowning, as if he was thinking about something, and looked very cautious.

"Mr. Nan, these are probably the problems. If we can solve them, the quality of our chips will definitely improve a lot." After Lu Jian finished speaking, he looked at Mr. Nan expectantly.

The Southern Chief loosened his brows and smiled helplessly, "Gong Lu, you are welcome."

"Okay, I will think of a solution to what you said, see if I can solve it, and give you an answer later."

Lu Jian understood that what he said meant that he would be responsible for these problems, and Lu Jian bowed very happily, "Then please trouble Nanfang, and I thank you on behalf of everyone in our CNC device project team."

Lan Mingda, who was standing with Lu Jian, quickly followed suit and bowed, "I'm sorry for the inconvenience!"

Nanchang waved them to get up quickly, "Okay, this is what I should do, you just concentrate on doing research."

As he spoke, he looked at the people who were making the chip, "Lu Gong, this chip is a good thing, but can this chip be mass-produced?" After all, he is the minister of the Mechanical Engineering Department, and of course he is also very concerned about production. task.

Lu Jian shook his head, "The current ones cannot be mass-produced temporarily. The domestic equipment and technology level are not good enough, and there is no mass-production equipment."

Let alone Huaguo, chips from other countries have not yet been researched, and where energy production is possible, a lot of equipment must be designed first.Moreover, the chip is a precision electronic device, and the equipment required must also be precision instrument production equipment.

Nanchang nodded and didn't continue talking, as if he was thinking about something.

While they were silent, two professors from the capital who had been researching chips spoke, "Gong Lu, can your chips be directly used by computers?"

Lu Jian was a little surprised when his name was suddenly called, but he quickly said, "It should not be possible."

The two looked a little depressed when they heard the words.
