bonanza

Several people expressed their ideas - electric discharge forming, and then high temperature treatment in graphitization furnace.

"Very good!" Yang Dongsheng nodded, "Then we will walk on two legs. You explore the production process, and I will provide materials for you to choose!"

The others nodded.

Yang Dongsheng looked at the director of the Materials Research Center again, "Has the critical temperature of superconductivity not come out yet?"

The director of the Materials Research Center hurriedly said, "It's being tested! We didn't pay much attention to this before, lacking relevant equipment and experience! However, it has been preliminarily determined that the superconducting critical temperature of this material should be between minus 183 degrees and 196 degrees. between……"

These two temperatures are the boiling points of liquid oxygen and liquid nitrogen, respectively.

Yang Dongsheng nodded and said, "Don't test it, it's enough!"

He was very satisfied with the answer, and it really was a high-temperature superconducting material.

It is strange to say that although metals are all conductive, their superconducting critical temperatures are very low.

The superconducting critical temperature of tungsten is minus 273.138 degrees, zinc is minus 272.4 degrees, lead is minus 265.957 degrees...

Yang Dongsheng did not transport all the alloys all at once, but first took a piece of alloy as a sample every [-] kilometers.

He is not only familiar with the buildings and roads of Moscow, but also knows many secrets that others do not know.

Anyone who reads it will think it is the specific number of the steel.

"That's the entrance to Moscow Metro Line 2!" Li Rufeng's second uncle pursed his lips as soon as the car got out of the airport.

Therefore, the MRI machines in hospitals are very large, and the operating costs are also very high.

Russia's per capita GDP has risen from US$2000 in 1772 to nearly US$1 now.

"Only part of it reaches 800 meters, not the whole distance! The total length is only more than 20 kilometers, from the Vnukovo Airport just now to the Kremlin." Li Rufeng said to his second uncle.

They can let go of their hands and feet, and make the aero-engine have greater thrust as much as possible, and the gas turbine has higher thermal efficiency.

What's more, Yang Dongsheng helped them a lot before, and now it's time for the Li family to repay him.

In 2004, after the international oil price broke through the US$40 per barrel mark in one fell swoop, it was unstoppable.

The leaders will visit Moscow at the end of March, and they are going to make a front stand.

"Is it the project that is said to be built more than 800 meters underground, with a total length longer than that of Moscow's civilian subway, and also capable of preventing nuclear bombs?" Yang Dongsheng was immediately curious.

After the luggage was checked in, Yang Dongsheng only took a coat in his hand.

Hearing Li Rufeng and his second uncle nagging, Yang Dongsheng looked out of the car window, looking at this strange city.

To make metal superconducting, liquid helium is often used.

The metal with the highest superconducting critical temperature is technetium, which is also minus 261.95 degrees.

Li Rufeng's second uncle took Yang Dongsheng directly into one of the commercial vehicles, and then began to serve as a free tour guide for Yang Dongsheng.

The prices of other natural resources are also soaring all the way.

Moreover, the boiling point of helium is minus 268.6 degrees. It is not easy to maintain such a low temperature. Liquid nitrogen is usually used as an insulation layer outside the liquid helium.

Unfortunately, according to previous test results, the hardness of this alloy is too high.

The production of this batch of aero-engines and gas turbines will definitely surprise the eyeballs all over the place.

Yang Dongsheng lost interest after hearing a few words, which were commonplace talk about good neighborliness and friendship.

They took a Boeing 777 charter flight this time. Yang Dongsheng and Vice President Huang were in business class, and the rest of the entourage were in economy class.

Just finding suitable materials among these alloys is enough for them to be busy for a while.

It was Li Rufeng and his second uncle who spoke.

"Everyone works!" Li Rufeng and his second uncle waved his hands, "Why didn't your private jet fly this time?"

Although the future of the Li family was ruined by themselves, at least they still look very good now, and there is no need for Yang Dongsheng to turn against them.

Then depart from Huajing International Airport and fly to Moscow.

The man in the Kremlin is now in full swing, and Russia seems to be only one step away from a developed country.

Li Rufeng's second uncle is very talkative, it seems that the Li family has really gained a lot this time.

Li Rufeng and his second uncle introduced him all the way.

It is too difficult to pull this alloy into a wire and make a coil.

After flying for about nine hours, the plane did not land at Sheremetyevo International Airport in the north of Moscow like most flights, but landed at Vnukovo Airport in the southwest suburb of Moscow.

He also explained to Yang Dongsheng some precautions for going to Russia, as well as what he thinks of etiquette.

Markers are used on each alloy to write the specific depth.

In addition, aero-engines and gas turbines have to be redesigned.

Huajing has warmed up in March, but Moscow is still close to minus ten degrees. The weather forecast shows that there will be heavy snowfall in Moscow in the next few days.

Moscow was really cold, and the agencies in Russia sent several commercial vehicles and buses to pick them up.

When passing by a building that looked like a church, Li Rufeng's second uncle said again, "Did you see that building? That underground area has been hollowed out long ago, and a huge combat command center was built. During the Cold War, Supplies for thousands of people to live for three months are also stored there all year round."

Moscow looks a lot of local luxury, Mercedes-Benz, BMW, Rolls-Royce, Bentley and other luxury cars are everywhere on the streets.

After omitting the cooling system, the structures of aero-engines and gas turbines can be greatly simplified.

"Dongsheng!" As soon as he stepped into the plane, a middle-aged man in his fifties waved at Yang Dongsheng and pointed to the seat next to him, "This way!"

"This time is a state matter, of course I have to act together with everyone!"

Yang Dongsheng nodded, sat down and said, "Are you going to stand up for the leader yourself?"

After everyone else left, Yang Dongsheng rushed to Vice President Wang, "We will set up a superconducting research team in the future!"

Two days later, Yang Dongsheng, Vice President Huang of Dongsheng Semiconductor, and a dozen staff members rushed from Shanghai to Huajing.

In particular, Dongsheng Semiconductor, the joint venture semiconductor factory they established with Russia, has to complete the acceptance work.

This is the beginning of the new century, the "golden decade" of Russia.

In contrast, our country's per capita GDP was just over US$2000 at this time.

Helium is a rare gas. Our country relies almost entirely on imports of liquid helium. The price per ton reaches tens of thousands of dollars, and it is still rising.

As the cars get closer and closer to the city center, the streets become busier.

On the street, many fashionable young men and women appeared.

I have to say that Russian women before marriage are indeed beautiful, with well-proportioned figures and exquisite facial features.

It was several degrees below zero, still wearing thin stockings, showing a pair of long legs.

Yang Dongsheng couldn't help thinking about whether he should bring two back?
