Chapter 2009

Qin Guan is also very speechless. Qin Guan is definitely not a qualified matchmaker. He doesn't care about other people's families. Now, major Yang generously said, "OK."

However, there was no following. The scholars on one side winked one after another, so Yutong could only stop the topic.

Looking at major Yang, there seems to be no difference, but seeing his mental point rise suddenly, we know that his mood must have fluctuated abnormally. He must have remembered something.

It's inconvenient for Qin Guan to ask again.

"Come on, let's watch TV." the scholar broke the embarrassment and turned on the TV. Needless to say, at this time, the whole earth outside has become a world wrapped in silver. For the north, the most comfortable thing is to stay at home, drink wine, rinse mutton and watch TV. Now, many families don't have TV. Here in Qin Guan, It's already a large screen LCD TV. From the dining table, you can't see the screen, but you can hear a clear sound.

Listening to that familiar tune, you know it's news broadcast. Moreover, the domestic news has passed, and there are five minutes left to broadcast international news.

"Now, we broadcast the latest news. Zhu * *, a Chinese born scientist in Yingguo, announced that they had obtained superconductors above 90K for the first time, which is very important for the study of superconductors."

Hearing this, Qin Guan's hands immediately stopped, and the chopsticks seemed to shake.

"Hum, if you want me to say, don't emphasize Chinese descent. They are all Chinese, but they don't want their own motherland, but they go abroad and join foreign nationality. Compared with our older generation Deng Jiaxian and Qian Xuesen, what are they?" the scholar's words were filled with discontent.

It is common for people to go up high, but they don't even want their own motherland. Such people are despised by scholars. Here is their own root. Where is there a person without a motherland?

"Hum, these people will say that they are doing research because the domestic level is low and can't realize their value. They are looking for a better platform. They only have scientific research in their eyes and have no national boundaries." the scholar continued, looking up and drinking a glass of wine into his stomach. Obviously, he began to sulk.

Seeing the scholar like this, Xiao Lu gently touched his hand. His hand gently put down the wine glass. He always listened to Xiao Lu.

"Superconductors are the most important thing in the country." Qin Guan said, "we must not relax in this regard."

In the past, Qin Guan didn't have this ability, but now it's different. Qin Guan already has this new system and found many things that can be easily obtained, such as this superconductor.

Ordinary conductors have resistance. Because of resistance, when the current passes through, it will generate heat and consume electric energy. This is also the interest dispute between the power plant and users. I sent out 5000 kwh of electricity, and I want to charge 5000 kwh of electricity, but the users refuse. The users only get 4000 kwh of electricity, so they pay 4000 kwh of electricity, and the remaining 1000 kwh, It's all consumed on the transmission line.

Of course, the actual gap is not so large, which is also the reason for the use of high-voltage transmission, but there must be losses. But unlike superconductors, superconductors have zero resistance.

What are the benefits?

The first is to save the energy loss of transmission. If superconductors are used as transmission lines and power stations to users, there will be no loss.

However, this is just a dream. No transmission line uses this material because it is too expensive.

The biggest difficulty of superconductors is temperature. When superconductors were first discovered, the mercury coil was reduced to near absolute zero, and the resistance suddenly disappeared.

The effort to reduce the temperature to absolute zero is great, at least in terms of current technology.

Therefore, countless scientists began to devote themselves to the research of high-temperature superconductors. Although they are called high-temperature superconductors, they are still more than minus 100 degrees. Among the commonly used low-temperature objects, liquid nitrogen is minus 196 degrees. If the critical temperature of superconductors is between absolute 0 degrees and minus 196 degrees, they are low-temperature superconductors. Those above - 196 degrees are high-temperature superconductors. If superconductivity can be achieved at daily temperatures, they are constant temperature superconductors.

Now, we are gradually increasing this critical temperature. This 90K temperature has reached the temperature range of liquid nitrogen, which means it is easier to use. This is definitely a major discovery.

"Superconductors, for us, are most useful for electromagnetic ejection, including electromagnetic guns. The most important part of superconductors is superconducting coils." Qin Guan said: "we must carry out research in basic physics in this field."

At this time, the two children were full. Yutong took the two children to play in the children's room. At the same time, she also knew that their adults were talking about some very secret things, which was not convenient for them to know.

Qin Guan was already talking on the table.

"In the future, our aircraft carrier will inevitably use electromagnetic ejection. Our short-range protection weapons will also be replaced with electromagnetic guns. Even the main naval guns may be replaced with electromagnetic guns. Therefore, we must pay attention to the development of this system," Qin Guan said.

When it comes to weapons, major Yang is an absolute expert. Now, hearing Qin Guan's words, he can immediately outline a scene in his mind.

At present, the most mature catapult is the steam catapult. If there is electromagnetic ejection, it will definitely be regarded as a fantasy. However, Qin Guan knows that this is not science fiction. In 2020, the aircraft carriers of Eagle people and Han country began to use electromagnetic ejection, and the electromagnetic ejection of Han country is more advanced!

There are many advantages of electromagnetic ejection. There is appropriate acceleration in the whole process. At the same time, it is also convenient for light load ejection UAV, etc. now, we begin to carry out technical reserves and achieve a breakthrough in the field of high-temperature superconductors!

Moreover, in that parallel space-time, the research on high temperature superconductivity in Han Dynasty was originally advanced.

Now, Qin Guan is looking forward to it.

As long as the country makes up its mind, it can use its own system to exchange advanced superconductor research results. Hum, do you think it's easy to produce research results when you go abroad? The real potential power is the Han state!

"Yes, we really should make great efforts to do research in this area." major Yang said, "I'll report tomorrow, and you should be prepared."

Of course, Qin Guan knew what major Yang meant. He patted his chest: "don't worry, it's already ready."
