Chapter 454: Incredible materials technology

Everyone has played with magnets when they were young. They know what magnetism is and how strong magnetism is. (Top) (dot) .. o In ordinary people's impression, if a magnet the size of a fingernail is attached to a certain piece of iron, it can be easily pulled down with just two fingers. But this time, what they saw subverted their common sense, what kind of magnet is this!
The gate is obviously not a place suitable for science popularization, so a place called "ferromagnetic material exhibition area" was set up where everyone just entered the venue. In this exhibition area, there are pictures, texts, videos and other materials that introduce the principles, properties, applications, etc. of ferromagnetic materials, and there are many games designed based on ferromagnetic materials. For example, with countless short magnetic rods, a very sturdy Eiffel Tower can be set up. A mung bean-sized magnetic head can pick up dozens of pounds of iron pipes. There are also magnetic levitation rail cars based on permanent magnet materials. A group of well-dressed Spectators are sitting on such floating cars in the air like children and having fun.
Joris also wanted to stay in this exhibition area and play all kinds of fun things, but he came with a reporting task, no matter how rich he was, he couldn't be willful. He trembled while sitting on a swing attracted by strong magnetic materials, and let the cameraman take this thrilling scene, then left the strong magnetic exhibition area and continued to move forward.
The entire exhibition hall is divided into dozens of exhibition areas, and each exhibition area corresponds to one or several related materials. As in the previous case, the exhibitions in each exhibition area put great emphasis on entertaining features, or use blinding materials to brighten the eyes of visitors, or design various participating projects to let people experience the materials in person. Magical.
Such an interesting exhibition, Joris is naturally like a fish, with a microphone in his hand. Chattering, pretending to be cute, one area at a time:
"Let's take a look ... This is the solar material exhibition area, and the solar panels are displayed here. Yes, as long as you take a flashlight on this board, we see the electric fan connected to it It started turning ... I have to say. The wind is still very strong, and I feel a bit cold ... "
"... We finally escaped from the cold solar exhibition area. What, you said that I still had a flashlight from that exhibition area? No, no, I don't want to return the flashlight to that lovely commentator, because here The exhibition area has a greater effect. Do you see that there is a wall across the side, as long as I shine an electric light to the corresponding position on that wall, that wall will make a different sound ...
Let's try it. Wow ... it's so fun. I am now very skeptical that there are more than a dozen Chinese people hiding behind the wall, who are changing records based on the light of my flashlight. I came to the back of the wall. There are no lurkers we were expecting. The real mystery is on this wall. Here is a description: The material on this wall is called photosensitive ceramics, which can sense the change of light ... "
"Look, there is an interesting place in front, let's go over and see ... No, no, no. I don't plan to pass this suspension bridge, because the four ropes that suspend the bridge board ... what do you say. Bobby, you say them Not a rope, just four wires? Yes, yes, I agree with you, they are even thinner than my headphone wires ...
Look, two fat men weighing more than 200 pounds have already reached the bridge. I bet, they will definitely slam and fall down ... well, I admit that I lost, these four lines really can withstand 400 pounds. Let me see, here are the instructions. It is said that this thread uses high-strength high-modulus polyethylene fiber, and the abbreviation is sp ... Are you sure that such a long abbreviation is also called an abbreviation? "
"Okay, we finally returned to the forest. Behold, there is a river here, of course, it's just a model of a river. The water in the river is turbid, what experiments are they doing ... oh, they installed by the river A piece of polymer permeable membrane, a miracle appeared, and the river water became clear through this membrane.
We hear what scientists say, they say that this membrane can be used to filter drinking water on the battlefield and can filter dirty water into drinking standards. Bobby, come here. You said you were thirsty just now. I'm going to boo now and filter it into drinking water for you ... "
"..."
Almost all the audience, like Joris, was dizzying in the exhibition hall. For the first time in their lives, they learned that there are so many amazing materials in this world, such as what electrical functional materials, sensitive materials, magnetic functional materials, new energy materials, smart materials ... If they do n’t understand what these materials have, the booth There are rich introductions and physical displays, which is enough for everyone to understand.
Even steel, cement, ceramics, plastics, etc., which are commonplace in everyone's daily life, have changed their appearance at the exhibition. It is amazing that they have so much attention. Take ceramics as an example. Needless to say, there are ceramic cutters for cutting fruits. There are actually ceramic turning tools that can be used to cut metals. It is said that they are harder than diamonds and have truly reached the state of iron cutting. Slow down, isn't the ceramic itself mud? Use the mud to cut iron, and cut the iron like mud ... Is this the wrong rhythm of the script?
The general public is limited to watching the excitement, and some industry experts are hurrying to study the new trends of these materials. As for the visitors from the manufacturing enterprises, they are thinking more about whether these materials will affect their product design and whether their products can take them to a new level.
In a luxuriously decorated VIP room upstairs, a dozen people sat on a circle of sofas. In the middle is an elderly man with a gentle smile on his face, listening to the report from the organizer and deputy director of the Planning Commission, Wang Hongsheng:
"Head, the purpose of this exhibition is to do so, mainly to popularize the knowledge of materials science to the general public, and to arouse society's attention to materials. In manufacturing, materials and processes are two major factors. The two biggest gaps in foreign countries. Take aero engines as an example, we can imitate foreign engines to make identical blades and turbine disks, but because the high temperature resistant materials lag behind foreign countries, the service life of the engine is only 10% of foreign advanced levels. one."
The head nodded and said, "Yeah, I just read your introduction materials on high-temperature materials for aviation in the exhibition area, and I was very impressed. In the past, the Commission of Science and Industry also reported this issue to the central government, but it cannot be denied that the central government The attention in this area is far from enough, too little investment and too much debt. "
Wang Hongsheng said: "Materials are a century-old plan. Both factories and equipment can be purchased, and many industrial products can be imitated, but the material formula and process cannot be imitated, and they can only be explored by themselves, and this time may take decades or even more. A hundred years. Therefore, other things can be delayed, and material research cannot be stopped for a moment. "
The chief turned his head and looked at Qin Hai, who was sitting on the edge of one side, and said, "Comrade Xiao Qin, I heard that you have built a material school yourself, and you have dug hundreds of outstanding material experts from universities and research institutes. Going to work for you, is there such a thing? "
As soon as the Chief Minister made these remarks, officials from various departments participating in the talks set their sights on Qin Hai. Among these people, some knew Qin Hai before, such as Yang Xinyu, Cui Hongchun, and Deputy Director Bai of the Science and Technology Commission. They all knew more or less about the Anhe Material College. In addition, some officials only came into contact with Qin Hai when they came to visit the exhibition today. They did not know that he had such a large handwriting. They were shocked when they heard what the Chief Minister said.
A private company has dug hundreds of scholars from universities and research institutes. This is a matter of dismantling the corner of the country anyway. The head asked such a question in the face, did he have to hold the young man accountable?
Qin Hai was not surprised by the issue of the chief. He knew that a few days ago, the chief had summoned Shi Lao, Li Lao and others on the issue of material exhibitions. During the meeting, the leaders told the head of the domestic material science community and mentioned Qin Hai and his Anhe Material College. Shi Lao and Li Lao both had disciples and grandsons working at Anhe Materials College, and heard about the reasons. When introducing them to the chief, they had a lot of praise for Qin Hai.
With such a pavement, the director's raising this question should be just a pretentious gesture, and not to confess to Qin Haixing. Qin Hai believes that what he has done can withstand scrutiny, so he is very reliable.
"Director ~ EbookFREE.me ~ The situation you said does exist. We have an Anhe Materials College under the Daqin Industrial Group. There are currently hundreds of outstanding domestic material scientists working there. Many of the materials research you see today Achievement is from the Anhe Material College. "Qin Hai replied calmly.
The chief asked: "These scholars are the backbone of schools and research institutes. If you dig them all out, wouldn't you pry at the corner of the country?"
Qin Haidao: "Head, you misunderstood. I did not dig these people, I just picked them up."
"Haha, pick it up? This is a fresh statement. Tell me something." The chief said with a smile. Just as Qin Hai analyzed, the head did not mean to blame Qin Hai, but just wanted to hear how Qin Hai explained his behavior.
Qin Haidao: "The scholars recruited by the Anhe Institute of Materials are hard to stay in the original unit and are ready to go to the sea or go abroad. Even if I do n’t take them in, they will not stay in the original unit. Instead of letting them all Jumping into the sea might as well be picked up by me in the net and raised in the School of Materials, at least to retain the seeds of materials research for the country. "
"Is this really the case?" The director asked, staring at Qin Hai. (To be continued ...)
