"My Jiajia is so powerful, you can introduce new materials by trying it casually. Li Yuanling smiled and took out a handkerchief and wiped the fine sweat on Ning Wanjia's forehead.

For researchers like Li Yuanling, who are often in contact with the frontiers of scientific research, guidance is really an ordinary thing.

Substances in nature, when the temperature is below 5K, one-third can produce conductive phenomena, Li Yuanling knew that the three of them were testing and comparing the materials of the electromagnetic gun lead coil in the past two days, so they thought that the three of them were rare and strange, and they didn't take it to heart at all.

"Aunt Liang is not ....... Ning Wanjia, who was a little anxious, was speechless for a while, not knowing where to start with this question.

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

Li Yuanling had a gentle smile on her face, picked up the water cup on the desk in front of her, took a sip, and asked a little seriously: "Tell Aunt Liang how you adjusted the elemental ratio of yttrium-barium copper oxides." ”

Li Yuanling knew that the Dongda Guidance Center had systematically trained the three of them on yttrium-barium copper oxides, and with the abilities, curiosity, and equipment owned by the guidance center, it was very possible to change the original formula of Dongda and find a new critical temperature of the conduction compound in the yttrium-barium copper oxide family.

"Mom, it's a brand-new compound, which has never appeared in the history of conduction, and if we advance our current two years in advance, the route of mankind to break through the barrier of liquid hydrogen in the field of conductivity will be completely rewritten. Liang Yuan looked at the corridor and said the new practical significance of the three of them in the most concise language.

This time, Li Yuanling completely understood the true meaning of Ning Wanjia's words when she entered the door.

"Bang" - "Bang" -

The glass in Li Yuanling's hand fell on the floor of the office, and after a rebound, it hit the steel support leg of the chair and shattered.

For three minutes, the room was dead silent, except for the breathing of a few people.

Faintly, the voice of a partition from 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 slowly became firm.

In fact, the new conductor appeared, and the two girls accepted it much faster than Li Yuanling, and it was precisely because of Li Yuanling's understanding that the more she didn't believe that such a thing could be miraculously born.

Li Yuanling looked at the stable expressions of Liang Yuan and the others, and the belief she had just established was violently shaken again, and her son usually didn't seem to be in tune. But Liang Yuan has always been much more reliable in this kind of big event.

Maybe...... , the three of them because they read the wrong record?

Thinking of this possibility, Li Yuanling's belief that it was impossible to live slowly became firm.

I got up the phone on the desk in front of me and connected directly to the administrative office.

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

"Where is your Zhou Heng?"

"Let him come right now, yes. At the entrance of the gas turbine workshop, the sooner 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, so she won't believe anything, go to the guidance center with your mother, and repeat all the steps of the three of you just now." ”

"Okay. Okay, it's best for Aunt Liang to follow the guidance, and we don't believe what we just saw. ”

The two girls said with great approval.

Seeing the three women hurriedly come out of the door, Liang Yuan smiled proudly, picked up the tool kit on the ground and put it behind his back and walked out of the door.

"Squeak--"

Two corners from the gate of the gas turbine workshop, a sharp sound of brakes came from outside.

Liang Yuan followed Ning Wanfei out of the main entrance of the workshop, and Zhou Heng had already opened the sliding door of the sea lion bread. There were a few people waiting in the driver's seat.

"Xiao Zhou, go to the guidance center, the sooner the better. Li Yuanling, who finally got into the car, closed the door heavily.

"Mr. Li, is that the guidance center of Dongda?" Zhou Heng's voice carried a trace of puzzlement.

Listening to Fu Juan's tone, it seems that something happened Li Yuanling was in a hurry to use the car, but this location was too close.

Seeing Li Yuanling nodding his head in confirmation, Zhou Heng threw his confusion aside. As soon as I kicked the accelerator to the end, the scream of the starting tire suddenly sounded outside the car, first for a moment, and then for a slam. In the blink of an eye, the degree of the sea lion was raised to 3o yards and gone.

There was no word all the way, and it only took a minute, Zhou Heng drove to the door of the East Dadao Center, and Li Yuanling, who was a little anxious, opened the door before the car stopped.

The entrance of the No. 3 real yàn room of the guide center.

The cheap green iron lock nose imprisoned the pair of light yellow wooden doors in the No. 3 Daoshi yàn room, and Liang Yuan noticed that the three-ring lock he used when he just left with the two girls was still crooked with the trademark nameplate facing up, and it seemed that no one had been here during this time.

Digging out the key to the real yàn room from the tool kit behind him, Liang Yuan opened the opposite door of the real yàn room and walked in.

"Xiaoyuan, where is the new material you are talking about?" Li Yuanling looked around.

"Mom, I've said it, this thing is a cross-generational present, where can it be placed in such a public place. Liang Yuan chuckled and took out the bottle containing magnesium diboride from the toolkit behind his back.

"What is this, a family compound that resembles yttrium, barium, copper, and oxygen?"

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

Yttrium-barium copper oxide and magnesium diboride are similar in color, both are blue-gray colors, but yttrium-barium copper oxide is more cyan, and magnesium diboride is closer to black-gray, and the two really look like an element family from the outside.

"Then it would be better to be a family of yttrium-barium-copper oxides. Liang Yuan said as he turned on the power of the circulating freezer.

Liang Yuan took out the two magnesium diboride wires prepared by Ning Wanjia and handed them to Li Yuanling, saying, "Mom, this thing was prepared by Jiajia. ”

"In addition to lowering the temperature and pressure to reduce the difficulty and time of implementation, the other steps are prepared in accordance with the process of preparing yttrium-barium copper-oxygen wires. Liang Yuan said with a little smugness.

Watching Liang Yuan add liquid helium to the freezer, and then put the wire into the low-temperature constant temperature room, Li Yuanling's heart beat faster and faster as the rapidly falling number on the temperature indicator began.

A moment passed. When the reading on the temperature indicator was stable at 39K, Liang Yuan turned his head and gave Li Yuanling a big smile, and then unhurriedly turned on the test equipment - there is no doubt that the resistance is zero!

When Liang Yuan smiled and took out the label with the words magnesium diboride written on it, and matched the few traces of the label residue left on the bottle without any mistakes, Li Yuanling was stunned.

The facts are all there, and the evidence is ironclad, Newton's apple spans three hundred years of time and space. smashed on the head of his loved ones so dramatically, and an incomparably huge trembling sensation filled Li Yuanling's body and mind.

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

In 1987, the German physicist Bernoz, a German physicist in the IBM Research Laboratory in Switzerland, and the Swiss physicist Müller won the Nobel Prize in Physics, the highest honor in the global scientific community, for their heavy breakthrough in the electrical conductivity of ceramic materials.

Li Yuanling clearly knew that it was as early as the 7o years. Foreign researchers have made forward-looking predictions about the conductivity of ceramic-based complex compounds.

Bernorts and Müller began in '83 to find new conductive materials in ceramic-based complex compounds based on the Bcs theory of Nobel laureates Bardeen, Cooper and Schriever, and finally made a breakthrough in '87 after four years of hard work.

It can be said that before the emergence of yttrium-barium-copper-oxygen conductors, there have been theoretical predictions or verifications of this, figuratively speaking, although the light of the lighthouse is extremely dim, it is more than enough to guide the ship of human science to cross the dangerous shoals and reefs.

The magnesium diboride of Liang Yuan and the three of them is completely different. There is no theory in the world that shows that magnesium diboride is a substance that is conductive.

This means that the principle of magnesium diboride energy conduction is still outside human cognition, and for scientific and technological workers like Li Yuanling, this unknown is an incomparably huge scientific treasure house.

If the conductivity principle of magnesium diboride can be deduced, combined with the shocking results of the conductivity of the sub-present simple compounds, Li Yuanling estimates that the probability of winning the Nobel Prize in Physics that year is as high as more than nine layers.

For a moment, Li Yuanling even wanted to lose her old profession in aviation motivation. Changing majors to study guide materials, the attraction of the Nobel Prize for scientific and technological workers is self-evident.

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

Li Yuanling is much clearer than Liang Yuan about the importance of conductive materials to the future of mankind, and if the performance of magnesium diboride is good enough, it is not impossible to obtain a status similar to the two bombs and one star of the Republic. Even if the performance of magnesium diboride wire is not good, it is precious to bring a new research direction to the material industry of the Republic.

Suddenly, a bold idea rushed into Li Yuanling's mind, if the performance of magnesium diboride wire is okay, can this material be exchanged with the United States for its world-leading single crystal alloy casting technology in the field of aviation motive?

As soon as I thought of this possibility. Li Yuanling's whole person was excited, and at least half of the credit for the United States' unique position in aviation motor technology was due to its high-performance single crystal alloy.

From the principle of turbofan motor, the blade is the basis of the aviation motor, belongs to the core of the core, there is no excellent high-temperature alloy, the design is excellent, the electronic system is advanced in the air, on paper, it can be said that there is no single crystal superalloy as the foundation, there is no modern high thrust-to-weight ratio aviation motor.

At present, the F4o4 and F1oo series aviation motors equipped by the United States, and the cmF56 and p4ooo series large ducted turbofan motors in civil aviation all use second-generation single-crystal superalloy blades such as pa1484 and Renen5.

However, in a blink of an eye, Li Yuanling realized the difficulty of this matter, this kind of Cheng Dù's technical exchange is definitely not something that Yuanjia's small body can play, there are simply too many things involved, and for a while, the difficulties that he can think of are pouring out one by one, and Li Yuanling's brows are gradually twisted together.

Liang Yuan saw that his mother, who had always been calm and calm, and was intellectually generous, was stunned at first, then her eyebrows fluttered, and finally turned into a sad face, and he knew that Li Yuanling had realized the huge influence or explosive power that this matter could bring.

Liang Yuanxin said that the new conductive material, a big killer weapon, is in operation, which is comparable to the republic's unique hydrogen bomb miniaturization technology, and at that time, whether it is a sharp weapon in hand, whether it is a shortage of technology with the old and American countries with deep pockets, or digging a big hole to watch Western countries fall into it, and spending hundreds of billions of dollars of money to study those technologies that are destined to decline, it is a lovely event that is quite in line with his own aesthetic views.
