Since I Was a Special Soldier

The study of superconductors is also one of the most important directions for human future research, because the role of superconductors on humans is very extensive, from the most common superconducting power generation, controllable nuclear fusion, superconducting power transmission, and various magnetic levitation trains, automobiles , And even magnetic levitation skateboards, etc., as long as they have them, they can be researched out.

　　 But there is only one condition for all this, the normal temperature superconductor.

　　 That is to say, room temperature superconductors can achieve superconducting state under natural environment, but such materials are currently not available!

A few years ago, there was a discussion about the double-layer graphene material staggered by 1.1° to achieve a superconductor. It seems to be a normal temperature superconductor. In fact, it can't be regarded as a superconductor, because it needs to be manufactured under the condition of 1.7 K, which is sub-zero. 271.45°C.

Therefore, it cannot be regarded as a normal temperature superconductor in the strict sense. For humans, it is still very difficult to prepare at a temperature of 1K. Of course, it has been discovered that people have been working hard, but the preparation of graphene has always been relatively speaking. The cost is relatively high, and its application is more difficult, so at present, this material is not strictly a room temperature superconductor.

　　Moreover, the three parameters of superconductor, critical transition temperature, critical magnetic field strength, and critical current density, must be within critical conditions at the same time for superconductivity to be considered valid. In fact, for example, in actual use, it is possible that the natural temperature fluctuations from summer to winter will cause superconductivity to fail.

Sometimes a change of plus or minus one or two degrees Celsius will cause the superconductivity to fail, but this kind of metal material can reach the superconducting state at minus 60 degrees Celsius. More importantly, its three critical parameters are very high. , Especially its superconducting temperature is very wide, which means that part of the temperature fluctuations will not interrupt its superconducting properties.

　　-60 degrees Celsius is already considered as an ultra-high temperature superconductor in the superconducting world.

　　Because the high temperature in the superconductor world is not the same as the high temperature we recognize, don’t others tell you about ultra-high temperature superconductors, you will think that the ultra-high temperature is hundreds of degrees Celsius or something.

　　 Actually minus 200 degrees Celsius is considered a high-temperature superconductor in the superconducting world.

　　 So if the alloy superconductor of minus sixty degrees Celsius is said to be a normal temperature superconductor, because the temperature in nature will also be minus 60 degrees Celsius, as long as the natural world can reach it, it can be regarded as a normal temperature superconductor.

Relative to its critical transition temperature, its manufacturing can be said to be high-quality and low-cost compared to all other superconductors. Of course, this is only a relative term, but if large-scale industrial preparation is made, its cost will inevitably be greatly increased. decline.

　　 At that time, there will be more and more places where it can be used. Superconducting materials will change the human society tremendously, such as the future superconducting quantum computers, which can completely change the entire human society.

Jiang Yanhai felt that he was holding a key in his hand, but he couldn't take it out immediately. The main reason was that he mentioned in the acceptance speech of the National Highest Science and Technology Award that he wanted to study controllable nuclear fusion. It came out in less than two weeks...

　　 This is a bit too abnormal.

　　 The outside world does not know what is going on with Jiang Ling, but can Jiang Yanhai not know?

　　 So, he is ready to delay for a while, and he has a backup idea, which is to find an excuse.

　　 This excuse is nothing else. It happens that there are aliens in the world of the prophet, and the technology of those aliens is indeed far beyond their technological level. As long as you push there, everything can be explained.

　　 Of course, Jiang Yanhai feels that his research is nothing, because a controlled nuclear fusion is really nothing. There are more perverted things waiting for him to study. You can't just push it over there for any excuse.

　　 It happens that the structure of this controllable nuclear fusion has been calculated in China, but they have made some errors in the calculation of some materials.

　　 Superconducting materials are not impossible to calculate. In fact, before the emergence of the Pangu system, the use of supercomputing to calculate some materials that may appear superconducting is something that the scientific community often does. Of course, some of these calculations are accurate and some are inaccurate.

　　 Because human beings generally understand materials as little as they understand the universe.

　　 All matter atoms, human beings currently understand and master too little, in fact, sometimes science and mythology are really interlinked.

　　 Myths pay attention to the subtleties to see the true knowledge, pay attention to the big world, the small world, pay attention to a flower, a world, a grain of sand represents a world, and so on.

　　 actually makes sense.

　　 If you really understand microscopic particles thoroughly, then you will also understand the entire universe.

　　 If you can really control all microscopic particles, then you can also control the entire universe. This is really not an exaggeration.

After storing all the data ~www.wuxiaspot.com~Jiang Yanhai didn't say much. If the team researching and designing this brand new controllable nuclear fusion device has developed similar materials, then it is best. If it can't be done. If so, Jiang Yanhai will definitely have to take it out sooner or later.

I stayed in Rongcheng for another three days. During the day, Jiang Yanhai was engaged in phantom affairs with Professor Liu, and at night, Jiang Yanhai was studying this new material because he found that this new material seems to be very malleable. It is not only a superconductor, it can also be used in other fields.

On the fourth day, Jiang Yanhai and others left the research institute here and took the morning flight to Pengcheng. Naturally, it was impossible for Ye Cunxin and the others to enter the research institute. They studied all the specialized security personnel and they were responsible for related safety work. , It is impossible for outsiders to enter.

　　 But when Jiang Yanhai left, Ye Cunxin and the others could naturally follow.

When they arrived at the airport, Jiang Yanhai and the others were the first to board the plane as first-class, but when Jiang Yanhai approached the plane, his ears suddenly rang Erdan's reminder: "Warning, commander, the plane found dangerous materials. Whether to cancel the trip."

　　 Jiang Yanhai was taken aback for a moment, dangerous materials? Isn't the airplane body dangerous? This means that people who have ideas about him have to do it?

　　 "What dangerous material?" Jiang Yanhai didn't react at all on the surface. Anyway, Jiang Ling's personality has always been relatively cold, and everyone else knows it.

"A special coating on the windshield of the co-pilot of an aircraft. This material will change greatly when the outside temperature reaches a certain low temperature, which will cause the performance of the aircraft windshield to change, and the aircraft windshield will break. "Erdan immediately gave the answer.
