After the research of magnesium diboride is getting better and better, almost all the major research institutions in the world have reached similar conclusions, and the cost of magnesium diboride wire, which has been studied for more than ten years at that time, is less than one third.
The biggest realistic trend of magnesium diboride conductor replacing Y-Ba-Cu-O high-temperature conductor and Nb-O series conductor is that after Xu Xiaoxing (Note 1), a scientist from the Republic of China who studied in the United States, broke through the technical difficulty of industrialized mass production of magnesium diboride thin films, the United States, Japan and other powerful countries released the preparation technology of Y-Ba-Cu-O high-temperature conductor and Nb series conductor to the Republic overnight.
At that time, a new wave of mass introduction of wire manufacturing technology was set off in private and state-owned enterprises in the Republic.
Twenty-one years before Liang Yuan was thrown into this world, with the maturity of magnesium diboride conductor, the manufacturers in the United States supported magnesium diboride and supported yttrium, barium, copper, oxygen, high temperature conductor and niobium column conductor.
Although the United States, Japan, Europe and other industrial consortia have just perfected and optimized the Y-Ba-Cu-O high-temperature conductor and Nb-column conductor due to the investment of hundreds of billions of dollars in the past ten years, the mass industrial manufacturing method can be strong and self-supporting, but the conductor is still gradually defeated in the face of the great competitive advantage of magnesium diboride conductor.
Liang Yuan is about to cross the front and rear ball, which will enable the wire material industry to produce high-end medical equipment magnetic resonance imaging instruments on a large scale. The main manufacturers, such as ge in the United States, Philips in the Netherlands and Ximendu 6 in Germany, continue to introduce a new generation of magnetic resonance imaging instruments based on magnesium diboride wire coils.
In the military industry, a series of military equipment such as American Tomahawk cruise missile, standard anti-train missile, F1 fighter radar and F16 fighter radar have been installed as early as 25 years ago.
Liang Yuan was able to learn about the phase information of magnesium diboride conductive materials or when Dr. Xu Xiaoxing was hired as a visiting professor at Peking University and gave a speech at Dongda University, he was forced to listen to it by Cai Xiaobing who was fooling around in the sea of scientific research at that time.
Liang Yuan insisted on bringing the maglev project into the overall planning of the regiment, and the big Bug of magnesium diboride was the most important reason.
The hardware platform built by excellent wire materials and high-performance industrial chips will be the future crown in the field of medical devices-the core system of nuclear magnetic resonance imaging instrument after matching the appropriate operating system and analysis software.
However, in the military field, the performance gap between guided device equipment and non-guided device equipment is not one time, but two times is often fifty times.
Similar to the lunar rover of the Republic of China landing on the moon in the new century, if the communication guide device is not faced with the remote distance from the moon, the remote control instruction will be completed
It can be said that it is impossible for non-conductive device equipment with the same power to interfere with the equipment base containing conductive devices.
Technology has a revolutionary impetus to power, energy, transportation, military industry, medical treatment, communication, semiconductor and other industries.
Liang Yuan got this level of killer out more than ten years ago. Whether to choose technology trading or quietly study the party and state is a strategic card for Yuanjia at this time.
Of course, in the face of this kind of pit, which has great interests and is full of right and wrong, that is, two girls accompany Liang Yuan, otherwise I dare not play this knife-tip dance by borrowing Liang Yuan’s sun.
Staring at this black bottle in front of me, I know that it’s done. Liang Yuan can’t bear the excitement in his heart. Go back and take the girl behind him and hold Ningwanjia in her arms.
The girl’s dark fragrance is mixed with chemical reagents, and the unique bitterness turns into a very specific and bitter smell, which rushes into the nasal cavity. The reason is excitement and thumping and jumping, and the heart rate is getting faster.
Listening to some heavy breathing of childhood friends, I felt Liang Yuan’s nose and mouth hot air spraying his collarbone, and an indescribable heat rose from my body. Ning Wanjia felt that she was half strong again.
"Little far away, people are breathless." The girl’s voice is soft and light and greasy, and she goes straight into Liang Yuan’s heart.
In the bosom, the eyes are full of water vapor, like drops of powder, and the lip lines are shining with delicate shimmer. As the girl breathes more quickly, she fills the corner.
Do you want to kiss Liang Yuan and think about hanging yourself half-way? Ning Wanjiabei’s teeth are slightly exposed and her lips are half-open. It seems that peach blossoms just spit out. It looks very sweet and sweet.
"Did you two find Xiaoyuan? I have found two materials." Ning Wanfei broke the ambiguity between Liang Yuan and Ning Wanjia with a full voice.
"The horse is chosen" Liang Yuan suddenly felt that his gall had moved to his tongue.
In the bosom, Ning Wan Jia looked at Liang Yuan with five senses, first gave Liang Yuan a charming smile, and then circled Liang Yuan’s neck and gently kissed Liang Yuan’s mouth.
"Let’s take these two in the past, just one black and one white." Ning Wanjia pointed to two glass bottles containing sodium hydroxide and magnesium diboride reagent in front of them and said.
It’s obvious that Ning Wanjia just remembered that little bully with black face and black gun.
"Jia Jia which have so dark" Liang Yuan said with great shame.
Without talking, the slandered girl gently rolled up her T-shirt cuff, and a piece of lush forearm was exposed, and most of it was pulled over someone’s arm and placed together, and then she looked at Liang Yuan with a smile.
Liang Yuan smiled and pulled back his arm, picked up two glass bottles, one black and one white, and put them into the carry-on kit. Then he said casually, "I am a winter protective color, dark color is easy to absorb solar radiation, and it is beneficial to keep warm in winter, which is very in line with the logic of biological evolution."
"Pig head, let’s have a better summer." Ning Wanjia smiled and pinched Liang Yuan’s ear and dragged someone to the door.
Ps Note 1 The actual reference is that interested friends of Xi Xiaoxing can search the information of this schoolmaster.
Chapter 261 Go against things ()
"What did you two find?" Ning wanfei asked
"What did Sister find?" Ning Wanjia took two strip objects in Ning Wanfei’s hand.
A black carbon rod and a gray tin bar are fairly common in chemical experiments of these two materials.
"Black and white double evil spirit" Liang Yuanxiao took out two bottles in the toolkit.
"Sodium hydroxide and … magnesium diboride?"
"What does Xiaoyuan magnesium diboride do?" Ningwanfei curious asked
"I don’t know, but I vaguely remember which teacher told me that this thing was set off in fireworks. In fireworks, it was bright silver and boron seemed to be green," Liang Yuan said with some uncertainty.
"There is one left. What material shall we choose? Oh see more dizzy "looking at eyeful glass bottle NingWanJia finals said.
"Let’s look for mercury separately. At least it is the first time in human history that existing conductive substances have been written into the project report, which can also add some heavy historical flavor." Liang Yuan said with a smile.
Two girls nodded, three people shook the room for five or six minutes, and finally prepared five kinds of comparative materials.
When leaving the laboratory building, the doorman was suspicious and looked at Liang Yuan’s back kit, which was covered with the seal of the school. Please ask all units to assist Liang Yuan, Ning Wanjia and Ning Wanfei in preparing for the Youth Science and Technology Innovation Competition, which played its due role.
Liang Yuan successfully took five kinds of contrast materials out of the experimental building without checking them.
It’s also a trouble, otherwise, nine times out of ten, the laboratory building manager will be involved in the vortex after the explosion, Liang Yuan thought to himself.
Three people back to the guide center is more than two o’ clock in the afternoon Ning Wanjia took out three bottles of mineral water from the corner freezer and handed them to Liang Yuan and Ning Wanfei for a short rest, and then three people did a comparative test.
I don’t know whether magnesium diboride, sodium hydroxide, carbon and tin can guide Liang Yuan at all. To avoid the first one, I will do experiments with magnesium diboride and practice my hands with mercury before Liang Yuan goes out.
The two girls are also excited, curious and uneasy about verifying the comparative materials, and they all praise Liang Yuan’s suggestion.
Mercury conductivity detection is easy to connect with liquid helium refrigeration cycle freezer. When the temperature of heat insulation equipment drops by 42k, the mercury resistance suddenly disappears.
Liang Yuan repeated this copy according to the process of testing mercury conductivity, which had been verified by predecessors, while the two girls concentrated on remembering a series of test data in the test report.
At 1437, the refrigeration equipment is running normally. Compared with the measured resistance of mercury cooling 79k …
At 1443, the measured resistance of the mercury temperature of the contrast material was 23k …
Measured resistance of 1452 points compared with mercury temperature of 41k.
Liang Yuan slowly observed the test data in real time.
"Well, we’ve all finished recording Xiaoyuan." Ningwanfei waved the folder in his hand.
"There are still four people who have completely finished testing the magnetic cannon," Ning Wanjia said excitedly.
"Xiaoyuan, do you think our magnetic cannon can win the prize?"
"If the original wall can be torn down, it is estimated that 10,000 flowers can be cheated, and now this can be mixed with 3,000, so thank God." Liang Yuanxiao said.
Liang Yuan’s heart knows the belly. Although it seems magical to ordinary people, it is definitely not as good as Wang Mengmeng’s form processing system in the eyes of the academicians of Qingke Competition.
If Cai Ning Wan Jia suggested that the magnetic gun should be renamed as the earth orbit propulsion device and then the conductor coil drive should be changed into the reconnection orbit, there is still a glimmer of hope to win the highest award in terms of creativity.
Now the magnetic cannon has been torn apart by Liang Yuan, and it doesn’t even have the visual shock to pierce the coin. If you can judge the third prize, nine times out of ten, you should look at the wire coil that is extremely difficult to process.
"Xiaoyuan’s big scam also said that he would shock those old men in Peiping." Ning Wanjia took a white look at Liang Yuan.
"It’s good to have this ending. Destroying a wall and a cabinet has successfully made things. Xiaoyuan is second only to the fan." Ning Wanfei said with a smile.
"You two are already rich women, don’t be so greedy, okay?" Liang Yuan rubbed his white cheeks around the girl.
"One, what do we test?" Liang Yuan asked, pointing to the remaining four materials.
The force stretched a curve, exquisite and slender waist. Ning Wanjia yawned and said, "Take advantage of the present spirit to get those two powders first, or it will be easy to fail when you are sleepy for a while."
