"My Jiajia is so amazing. You can find new superconducting materials by just trying it out." Li Yuanling smiled and took out her handkerchief and wiped the fine sweat from Ning Wanjia's forehead.

For R&D personnel like Li Yuanling who often comes into contact with the cutting-edge scientific research, superconductivity is really something ordinary.

When the temperature of the substance in nature is below 5K, one-third of the substances can produce superconducting phenomena. Li Yuanling knew that the three were experimenting with comparing the materials of the electromagnetic gun superconducting coil in the past two days, so she thought that the three were rare and didn't take it to heart.

"Aunt Liang is not..." Ning Wanjia was speechless for a moment, not knowing where to start this question.

"Aunt Liang, the critical transition temperature of the superconducting new material we discovered is 39K, which has broken through the liquid hydrogen barrier." Ning Wanfei, who loves martial arts, finally calmed down a lot and directly pointed out the key data.

Li Yuanling's gentle smile slightly, she picked up the water cup on the desk in front of her and took a sip, and asked seriously: "Tell me about Aunt Liang, how do you adjust the proportion of yttrium barium copper oxygen compounds?"

Li Yuanling knew that Dongda Superconducting Center had systematically trained the three people on yttrium barium copper oxygen compounds. With the three people's ability, curiosity and equipment owned by the Superconducting Center, it is also very likely to change Dongda's original formula and find a new critical temperature superconducting compound in the family of yttrium barium copper oxygen compounds.

"Mom, it is a brand new compound. It has never been discovered in the history of superconducting. If our discovery were two years ahead of schedule, the route of human beings to break through the liquid hydrogen barrier in the superconducting field will be completely rewritten." Liang Yuan looked at the corridor while using the simplest language to express the practical significance of the three people's new discoveries.

This time Li Yuanling fully understood the true meaning of Ning Wanjia when she entered the door.

"Bang" - "Bang" -

The glass in Li Yuanling's hand fell on the floor of the office. After a rebound, it hit the steel support feet of the seat and smashed it to pieces.

It took only three minutes, except for the breathing of a few people, the room was as quiet as death.

A faint sound from the partitions elsewhere came from a distance. The stagnant air in the room was invisibly relaxed.

"How is this possible?" Li Yuanling's faint voice was like a candle in the wind.

"This is absolutely impossible!" Li Yuanling's voice gradually became firm.

In fact, the two girls accepted the discovery of a brand new superconductor much faster than Li Yuanling. It was because of Li Yuanling that he became less and less convinced that such a thing could happen miraculously.

Li Yuanling looked at the stable expressions of Liang Yuan and the other two, and the belief that had just been established suddenly became shaken again. Her son seemed to be unrestrained. However, Liang Yuan has always been much more reliable in such major events.

Perhaps..., the three of them misread the record because of their hands?

Thinking of this, Li Yuanling's belief that Li Yuanling's firm belief that it was impossible gradually became firmer.

I fucked the phone on the desk in front of me and directly connected to the administrative department.

"Xiaojuan, you're on duty." Compared to usual, Li Yuanling's voice was a little sharp.

"Where is your Zhou Heng?"

"Let him come over immediately, yes, the faster the better."

Putting down the phone, Li Yuanling stared at Liang Yuan and said word by word: "Xiaoyuan, my mother didn't see this kind of thing with her own eyes. She said she would not believe anything. Go to the superconducting center with her mother and repeat all the steps of the three of you just experimented."

"Okay. OK, Aunt Liang is the best way to follow the guidance. We don't believe what we just saw."

The two girls said incredibly agree.

Seeing the three women hurried out of the room, Liang Yuan smiled proudly, picked up the underground tool kit and walked out of the door.

"squeak----"

There are two corners left before the entrance of the gas turbine workshop, and a sharp brake sound comes from the outdoors.

Liang Yuan followed Ning Wanfei out of the main entrance of the workshop. Zhou Heng had already opened the sliding door of Haishi Bread. He was sitting in the driving position waiting for several people.

"Xiao Zhou, go to the superconducting center, the faster the better." Li Yuanling, who finally got on the car, closed the car door heavily.

"Mr. Li, is it the superconducting center of Dongda University?" Zhou Heng's voice was filled with confusion.

Judging from Fu Juan's tone, it seemed that something happened somewhere Li Yuanling was in a hurry to use the car, but the location was too close.

Seeing Li Yuanling nodding to confirm, Zhou Heng threw the puzzle aside. He kicked the accelerator to the bottom, and the scream of the starting tire sounded outside the car. He paused first, and then rushed suddenly. In a blink of an eye, the speed of the sea lion increased to 30 yards and left.

It took only one minute to drive to the door of Dongda Superconductor Center. Li Yuanling, who was a little anxious, opened the door before the car stopped.

The door of the Superconducting Center Laboratory No. 3.

The cheap green iron lock nose confines the pair of light yellow wooden doors of the No. 3 Superconductor Laboratory. Liang Yuan noticed that the three-ring lock he used when he just left with the two girls, was still tilted there with the trademark nameplate facing upwards. It seems that no one has been here during this period.

Extracting the keys of the laboratory from the toolkit behind it, Liang Yuan opened the opposite door of the laboratory and walked in.

"Xiaoyuan, where are the new materials you mentioned?" Li Yuanling looked around.

"Mom, I have said that this thing is a cross-age discovery, so where can it be placed in such a public place?" Liang Yuan chuckled and took out the bottle containing magnesium diboride from the tool kit behind him.

"What is this? It's a family compound that looks like yttrium barium copper oxygen?"

Li Yuanling took the bottle and turned it around a few times, but found that the label indicating the type of item on the bottle had been torn off, leaving only a few traces of white bottom traces.

Yttrium barium copper oxide compounds and magnesium diboride are similar in colors, both of which are blue-gray colors, but Yttrium barium copper oxide compounds tend to be cyan, while magnesium diboride is closer to black-gray colors. Both look like things from the same element family from the outside.

"Then let's act as the family compound of yttrium barium copper oxygen compound." Liang Yuan said while turning on the power supply of the circulating refrigerator.

Liang Yuan took out the two magnesium diboride superconducting wires prepared by Ning Wanjia and handed them to Li Yuanling, and said, "Mom, this thing is made by Jiajia."

"In addition to reducing the temperature and pressure to reduce the difficulty and time of the experiment, we have prepared the other steps according to the process flow of preparing yttrium barium copper oxygen superconducting wires. As for whether it can be superconducted, my mother will know in a while." Liang Yuan said proudly.

Seeing Liang Yuan adding liquid helium to the freezer and then putting the wire into a low-temperature constant temperature room, Li Yuanling's heart jumped faster and faster as the temperature indicator dropped rapidly.

After a while, when the reading on the temperature indicator stabilized at 39K, Liang Yuan turned his head and gave Li Yuanling a big smile, and then turned on the test equipment calmly - there was no doubt that the resistance was zero!

When Liang Yuan smiled and took out the label with the words magnesium diboride and met the remaining marks of the bottle, Li Yuanling was stunned.

The facts are all there, and the evidence is as strong as a mountain. Newton's apple spans three hundred years of time and space. It hits his close relatives so dramatically, and an extremely huge tremor filled Li Yuanling's body and mind.

As a pursuing and qualified first-class scientific and technological worker, Li Yuanling's understanding of superconducting materials is countless times stronger than Liang Yuan's big fool.

In 1987, German physicist Bonoz from the IBM Research Laboratory in Switzerland and Swiss physicist Muller won the Nobel Prize in Physics for his major breakthrough in discovering superconductivity in ceramic materials.

Li Yuanling clearly knew that as early as the 1970s, foreign researchers had already made forward-looking predictions about the superconductivity of ceramic-based complex compounds.

Bernolds and Muller started in 1983, based on the BCS theory of 1972 Nobel Prize winners Bardin, Cooper and Schriver, looking for brand new superconducting materials in ceramic-based complex compounds. After four years of hard work, they finally made a breakthrough in 1987.

It can be said that before humans discovered yttrium barium copper-oxygen superconductors, there had been theoretical predictions or verifications. It is vividly said that although the light of the lighthouse is extremely dim, it is still more than enough to guide human science to cross dangerous shoals and reefs.

The magnesium diboride discovered by Liang Yuan and the other two is completely different. There is no theory in the world that can show that magnesium diboride is superconductive.

This means that the principle of superconducting magnesium diboride is still beyond human cognition. For scientific and technological workers like Li Yuanling, this unknown is an extremely huge treasure house of science. What can be discovered in this treasure house of science that has not been explored yet? Just thinking about it is enough to make people excited.

If the superconducting principle of magnesium diboride can be derived and combined with the shocking achievements of the discovery of simple compounds with superconductivity for the first time, Li Yuanling estimated that the possibility of winning the Nobel Prize in Physics that year was as high as more than nine layers.

For a moment, Li Yuanling even wanted to lose her old profession in aircraft engines and switched to majoring in researching superconducting materials. The Nobel Prize's appeal to scientific and technological workers was self-evident.

It took half an hour for Li Yuanling to calm down her passionate mood, regain control of her emotions, and began to consider the consequences of this matter.

Superconducting materials are much more important to the future of human beings. Li Yuanling is much more clear than Liang Yuan. If the performance of magnesium diboride is excellent enough, it is not impossible to obtain a status similar to the two bombs and one satellite of the Republic. Even if the performance of magnesium diboride wire is poor, it is extremely precious to bring a new research and development direction to the Republic's material industry.

Suddenly, a bold idea came into Li Yuanling's mind. If the performance of the magnesium diboride wire is quite good, can we use this material to exchange with the United States for its single crystal alloy casting technology that stands out in the world in the field of aviation engines?

When Li Yuanling thought of this possibility, she became excited. At least half of the credit for the United States' unique aircraft engine technology is due to the high-performance single crystal alloy it has.

From the principle of turbofan engines, blades are the foundation of aircraft engines and belong to the core. There is no excellent high-temperature resistant alloy. The design is excellent and the electronic system is advanced in the air. On paper, it can be said that there is no single crystal high-temperature alloy as the foundation, and there is no modern high-thrust-weight ratio aircraft engine at all.

Currently equipped by the US military, the F404 and F100 series aerospace engines and the CMF56 and PW4000 series large ducted turbofan engines in civil aviation all use second-generation single crystal high-temperature alloy blades of grades such as PWA1484 and ReneN5.

However, in a blink of an eye, Li Yuanling realized the difficulty of this matter. This level of technical exchange is definitely not something Yuanjia can do with. There are too many things involved. For a moment, the difficulties she could think of came out one after another, and Li Yuanling's brows gradually frowned.

Liang Yuan saw that his always calm and generous mother was stunned at first, then turned into a frown, and finally turned into a frown. He knew that Li Yuanling had realized the huge influence or explosive power that this matter could bring.
