60s researcher

His brother and sister are a few years older than him, and his sister did not go to elementary school. She was married five years ago and has her own home.My elder brother went to the countryside ten years ago. He is already 28 years old. He did not get married in the countryside, and this time he is going to take the college entrance examination.His grandfather only had one son from his father, and two other daughters. Liu Luhua's parents were busy with work. After Liu Luhua went to high school, they let him live with his grandfather, which was regarded as being with his grandfather.

However, he also likes to be with his grandfather, and the two can chat about computer-related knowledge from time to time. Under the influence of his grandfather, Liu Luhua had already decided to major in computer science at Tsinghua University when he heard the news of the resumption of the college entrance examination. Grandpa is an expert in electronic technology, but he is more interested in programming languages.

After seeing the exam, Lu put it down. Anyway, the volunteer form had already been filled out, and the research on Longxing's second-generation personal computer had come to an end, so he got busy again.But this time, Minister Qu and the others didn't have time to come over, and they didn't need to entertain them. Lu Jian felt a lot easier here.

There was no ceremony, let alone a specific time. On the second day after Lu Jian's college entrance examination ended, Lu Jian and the others carried out the final assembly according to the established arrangement.The assembly went very smoothly, and then there was a long test time. They will finally form a test report, which will be handed in at that time. As for the production-related matters, the Ministry of Machinery Industry will naturally arrange it.

Because the test time is relatively long, they didn't all wait there, preparing to report the project in hand.Lu Jian also went back to his office, and called Jian Mingyuan and Xu Yan and Zhao Lei into his office by the way, planning to discuss future research projects with them.After all, a project requires everyone to work together, and it is still necessary to listen to other people's opinions.

Following Lu Jian into the office, Zhao Lei closed the door of the office without any hassle. The three found a chair to sit down very consciously. They have been used to it for so many years, and this is not the first time they have sat in.

As soon as he sat down, Zhao Lei couldn't bear it anymore. He has remained like this for so many years, and his personality can't be stable anymore. "See Lu, what do you have to say? I need to watch the computer test outside!"

Lu Jian didn't make any detours, and said directly: "Where is the test that needs you, they are enough."

"The project we're working on is over. Do you have any ideas on what to do next?"

As soon as he said this, the three people present fell silent, and they still had to think about this matter.

Lu Jian was not in a hurry, watching them think.

After a while, Xu Yan said, "See Lu, didn't the higher-ups arrange tasks for us?" In the past few years, they have been assigned some research tasks by the higher-ups from time to time, just like this Longxing second-generation computer, which is a business The Bureau strongly requested it, and the research task was only issued by the higher-ups.

Lu Jian shook his head, "There is no task for now, Director Huo asked us to arrange the project ourselves. But this project should not be too complicated, we will already enter a project by the end of next year."

Zhao Lei was very curious, "What project?"

Lu Jian: "It's a chip-related project, but this time, two projects will be carried out together, one is a lithography machine, and the other is an etching machine."

Xu Yan frowned, "Should these two projects be carried out together? This project not only involves electronic technology, but also requires high optical technology?"

Lu Jian nodded, "That's right, this project is jointly led by the Capital's Institute of Optics and the Institute of Chips, and it is expected that there will be a lot of people participating. By then we should go to the Institute of Chips for research."

Zhao Lei was a little puzzled, "Can we help with these two things?" Although electronic technology is also involved, Zhao Lei still feels that optical technology is more needed. They shouldn't be of much use in the past, right?

Xu Yan knocked him on the head, "Why can't help, these two machines are used to system chips, involving a lot of electronic technology, of course, including some mechanical knowledge, we just happened to be in the past."

Lu Jian nodded, "Xu Yan is right, but you need to add some knowledge about electronic technology. I will make a book list later. You can find time to read all these books. Before the lithography machine project starts, you Be sure to read it."

A few people nodded obediently, anyway, Lu Jian would make a book list for them after the interval, and they were already used to it.

Lu Jian was satisfied, but then he added: "And those researchers in our project team, you also hand over this book list to them, and they also have to complete this task. go."

Several people nodded. Now the three of them are in charge of a team respectively, and they are the team leaders of the project team.

After Zhao Lei agreed, he quickly said, "See Lu, then we don't have much time left. It should be impossible to do too complicated a project."

"That's right, there is only one year. Once the lithography machine project is ready, we will start researching it immediately."

Several people frowned in embarrassment, not knowing what project to do for a while.

Suddenly Jian Mingyuan on one side said: "Pocket phone?"

Lu Jian was startled, "Pocket phone?"

Jian Mingyuan nodded, and continued under the eyes of the three people: "Yes, it is a mobile phone. I have read a document before. In 1940, Bell Laboratories in country M had already produced a mobile phone for the battlefield. He invented the world's first commercial mobile phone in 1973, which is a very convenient phone terminal that can be used in a wide range. Compared with the landline, he can carry it with him and does not need a phone line."

Naturally, Xu Yan has also seen this information, and he frowned, "But what they researched is a portable cellular phone, right? It's about the size of a turning head?"

Jian Mingyuan nodded, "That's right, integrated circuit technology has developed rapidly, and the technology is relatively mature. Coupled with the in-depth research on electromagnetic waves, we can completely research mobile phones. You must know that in the 60s, we already had many dedicated The wireless telephone system, walkie-talkie, and intercom technology have already taken shape, and this is the prototype of mobile communication."

He has obviously studied it for a long time, and he speaks clearly and logically without any pause.

Lu Jian nodded, "The big obstacle is almost gone, but the battery?" Lu Jian didn't make a decision right away. Since he wanted to make a mobile phone, he naturally wanted to make the best one, and mobile phones are not like that Simple, there are still a large number of base stations to be laid, which is a big project.

Jian Mingyuan didn't pause at all. When Lu finished speaking, he immediately said: "It is said that the mobile phone invented by Bell Labs uses nickel-cadmium batteries, which can be recharged. We can try this kind of battery. When the time comes, you can invite several experts in materials and chemistry to help with the research.”

Without waiting for Lu Jian to speak, Xu Yan said first: "It seems that a material research institute in our country has already developed a nickel-cadmium battery, but this battery is a DC-powered battery, which can be repeatedly charged and discharged more than 5 times. Relatively fast, but the battery suffers from severe "memory effect" and has a very short service life."

Lu Jian also agreed very much and said: "Yes, nickel-cadmium batteries are also very toxic and have a great impact on the environment."

Jian Mingyuan was also silent for a while, this was also a problem, and he didn't know what to do for the time being.

"This idea is also very good, let's put it here as an option for now." Lu Jian thought for a while, but he was still not completely convinced. He was about to continue to look, and then looked at Zhao Lei, "Zhao Lei, do you have any ideas?"

Zhao Lei suddenly thought of something, "See Lu, didn't we say before that we want to study motorcycles? It's been more than ten years, or if we study motorcycles this time, I really want an extremely dazzling Cool motorcycle."

He looked at Lu Jian with bright eyes, full of longing inside, but Lu Jian had promised him this matter long ago.

Lu Jian did not expect that he would still remember this incident, "You want to study diesel motorcycles, right? You must first study diesel engines. The current diesel engines are large in size, high in noise and vibration, and low in speed. At least, are you sure you can change these problems? Time may not be enough, right?"

Zhao Lei is full of confidence, "Don't you need your help? Besides, sooner or later we will make our own small high-speed diesel engine. We can only research the diesel engine this time. I think the technology of electronically controlled direct injection You can try it, the previous method is not very good, we are researching electronic technology, we can make reasonable use of the technology at hand, can't we?"

Lu Jian didn't know that he had come up with the electronically controlled direct injection technology. He was a little surprised, but he still said: "But if we study this, then we don't have many people. Besides, Mr. Zhou and Mr. Lu have already You are retired, and now there is no one to help you."

This idea is quite good, but it is a pity that they are now in the computer research institute, people are really a problem, even if they apply to director Huo, they probably have to find cooperation with the mechanical research institute, or find an automobile factory for cooperation .

Zhao Lei did not give up, and smiled obsequiously at Lu Jian, "Jian Lu, help me apply to Director Huo, I don't need too many people, just a dozen or so can help me."

Lu Jian: "..." This Zhao Lei thought that this person wanted what he wanted, and he didn't go to the street to buy vegetables, not many, only a dozen or so, why didn't he go to heaven.But he didn't hit Zhao Lei, just said: "This matter has not been decided yet, let's talk about it when we determine which research to do."
