Chapter 718 Conductors

Guo Yang's journey to HKUST is not far, passing through an old vegetable market, and walking for another six or seven minutes to the gate of HKUST.

The gate of the University of Science and Technology is open, facing a small ginkgo avenue, but it is spring, and the scene full of gold leaves in the impression is still a few months later, but Guo Yang has not caught up.

Guo Yang tried to go as fast as possible, and let a group of old professors wait for him, but he was still a little unhappy.

The last time I had contact with Zhang Guoxue, Guo Yang felt pretty good, Zhang Guoxue is a typical scientist, the kind of person who is diligent and dedicated to society, Guo Yang admires this type of person.

And he is also very willing to associate with such people, because they are very easy to communicate with, and there is less disgusting calculation in the business world.

Being friends with simple people is a very relaxing thing.

hurried to the laboratory in the University of Science and Technology, outside, Zhang Guoxue had been waiting for Guo Yang for a long time.

He was such an expert professor, wearing a brown sweater and a white coat, standing at the door and looking around, like a child looking forward to his parents coming home. April in the capital is not a warm time, and now the weather has just come out of the sub-zero cold, hovering around six or seven degrees, and it is still very cold to wear such a body.

Guo Yang sighed a little in his heart, he took a few steps faster, Zhang Guoxue also saw him from a distance, at that moment, he shouted with a smile: "Guo Dong!

Guo Yang kept looking at him, when Zhang Guoxue called Guo Yang, the smile in the corner of his eyes was mixed with the deep crow's feet, in fact, as long as he carefully observed Zhang Guoxue, he would find that he was old.

Guo Yang trotted up, he rarely did this, this was the first time.

In front of Zhang Guoxue, Guo Yang said, "Professor Zhang, why are you standing outside?"

Zhang Guoxue didn't care about this topic, and replied casually: "Alas, I'm not afraid that you won't find a place, besides, you can't enter the door of the research institute, and I don't have anything to do now, so I'll come out to pick you up." ”

Guo Yang: "That's really hard for you. ”

Zhang Guoxue raised his eyebrows and said, "What's the hard work, I'm tough, come on, let's go in." ”

Guo Yang nodded silently, followed behind Zhang Guoxue, and once again walked into the research institute of the University of Science and Technology.

This time is different from the past, the last time Guo Yang came here, the researchers in the institute were doing something to each other, but today Guo Yang saw them gathered in front of a big screen together.

Although it is an advanced research institute in China, the equipment used is not even as high as that of a civilian computer in later generations, and the screen shows a design drawing that looks simple and clear, which should be the design of the pressure-sensitive screen. On the other side, there was a group of people on the other side of the screen, but the screen was relatively clean, and I didn't know what they were doing.

Zhang Guoxue led Guo Yang directly to the relatively clean screen, and said as he walked: "We researchers are divided into two groups, one group is to make a pressure-sensitive screen, and the other group is to start researching a capacitive screen. I remember that country M seems to have been researching this technology for a long time, and we roughly counted it, and the difficulty of this thing is quite great. ”

Zhang Guoxue said, but Guo Yang didn't have any ideas, because capacitor levels first appeared on Apple's first-generation Apple mobile phones, Guo Yang has some understanding of capacitive screens, but only some.

The so-called capacitive screen is like four pieces of glass pressed together, which have a conductive layer and an anti-static layer, and then set electrodes at the four corners of the screen, and through the current flowing through these four electrodes and the distance from the finger to the four corners, the data can be accurately analyzed, so as to judge the command message.

It's easy to say, but in fact, there are many, many problems in doing it.

Zhang Guoxue ignored the researchers who were discussing and calculating, and personally pulled a chair for Guo Yang, Guo Yang was not polite to him, and sat there directly, and then Zhang Guoxue didn't know where to take out a paper design drawing.

Zhang Guoxue came to Guo Yang, pointed to a place on the paper and said: "Guo Dong, you see, we have made a preliminary design for the capacitive screen, according to the information you provided, let us reduce the experimental time to a large extent, I have to say, your idea is very reliable and reasonable." ”

This person praised Guo Yang first, which made Guo Yang a little embarrassed, Zhang Guoxue was serious, but Guo Yang felt that he was a little thin-skinned. Never mind...... Just praise others, not the capacitive screen developed by Guo Yang, these praises should be given to those who dedicate themselves to science and technology.

Zhang Guoxue continued: "But we have not been able to figure out what kind of metal should be used for the conductor in the middle of this capacitor?"

This is indeed the biggest headache for Zhang Guoxue, four pieces of glass, among which there are also conductors, which are nothing more than some thin metal sheets, but in the materials they know, there is no metal that can be so thin.

Zhang Guoxue didn't wait for Guo Yang to think, and then said his second question: "Also, what should be used on this mobile phone to receive remote signals?"

At this time, the mobile phone signal is not as unfavorable as in the future, and it can be perfectly located in any corner of the earth, which Guo Yang thinks is very easy to solve, but the first point is ......

When the capacitive screen mobile phone first came out, Guo Yang was just unaware, and he didn't need to delve into the inner layer of science and technology as a media......

So, that's a tough question.

Guo Yang still said the second question first: "What you are talking about is how to send the mobile phone remotely, right?"

Zhang Guoxue nodded, he said: "Well, this is very important, although the country is now very peaceful, but over the years the military power has become the outline of the country's development, if you say that this technology can be realized, then at least it can fill in a layer of umbrella for all the soldiers, and the contribution is very huge!"

Guo Yang smiled, it seems that Zhang Guoxue is still too close, he only regards positioning technology as a kind of thing to find people, but does not take into account its wider use.

Guo Yang said: "This is actually not difficult, but it may require a lot of funds." ”

Zhang Guoxue became interested, and opened his mouth to ask, "What do you say?"
