February 1.

There are three days left until Chinese New Year's Eve.

Many people are already sticking Spring Festival couplets to buy New Year's goods.

Huang Haojie is still busy in various research institutes.

Under strong pressure, the dark red metallic oxygen, which is already a semi-finished product, is slowly transforming.

Li Xiang looked at the parameters of the instrument, and then recorded some data.

After these days of experiments, the Institute of Materials has successfully improved the stability of submetallic oxygen (dark red) to a very good state.

At this time, the density of submetallic oxygen (dark red) reaches 1971 kilograms per cubic meter, which can be maintained in the standard atmosphere below 46 degrees Celsius.

Below 46 degrees Celsius is the stable zone, 46~76 degrees Celsius is the relatively stable zone, and above 76 degrees Celsius is the unstable zone.

After a while, the semi-finished submetallic oxygen (dark red) in the instrument has become a denser and stable submetallic oxygen state.

The researchers took out the stable metallic oxygen from the instrument and went to the laboratory to test it.

"There is no problem with ordinary submetallic oxygen, and it can be produced on a large scale soon, but superconducting submetallic oxygen is very difficult to do." Li Xiang said helplessly to Huang Haojie.

Huang Haojie has already read the experimental report, superconducting submetallic oxygen is also light blue submetallic oxygen, the reason why superconducting submetallic oxygen is difficult to do is mainly the problem of mutation.

At first, Li thought that their experiment would be smooth, and in less than three days, the maintenance temperature of superconducting submetallic oxygen was raised to about minus 23 degrees Celsius.

However, after entering minus 23 degrees Celsius, the properties of superconducting submetallic oxygen have a sudden change, and after the pressure breaks through the critical point, the superconducting submetallic oxygen has the problem of superconducting properties suddenly disappearing.

The whole block of superconducting submetallic oxygen, after breaking through the critical point, becomes a dark red stable submetallic oxygen.

"There's a long way to go!" Huang Haojie had no choice but to spread his hands.

"I'm really unwilling! If superconducting submetallic oxygen can be stored at room temperature, the production cost will definitely not be as bad as that of iron-silver superconductors at room temperature. Li Xiang said unwillingly.

"Research is not infrastructure, and sometimes we are a little bit unlucky."

"I'm going to continue the project of room temperature superconductors, how about it?"

"You are the director of the Materials Research Institute, you decide."

"Then continue the project."

"Actually, we don't have to drill the horns, there are a lot of elements on the periodic table, why not try other elements." Huang Haojie proposed.

Li Xiang looked at him with some surprise: "Why didn't I think of it?"

"The authorities are obsessed." Huang Haojie replied with a smile.

"If I choose other elements, I think about nitrogen and sulfur to start with." Lee wanted to name two elements.

Huang Haojie is not much surprised by this answer, the reason why he chose nitrogen and sulfur is mainly because the reserves are huge and easy to obtain.

And those rare elements are not in the first consideration.

After all, Galaxy Technology itself has the product of iron-silver room temperature superconductor, if the cost of the newly developed room temperature superconductor is still the same bird, what do I want you to do?

Therefore, rare elements are the first to come out, rare gases such as helium, and tellurium, which is also an oxygen element, do not need to be considered.

Even if it is developed, the price must be very touching, and there is no need to do this kind of useless work.

Therefore, nitrogen, which has the largest atmospheric content, and sulfur, which is the oxygen group element, are the first choice for experiments.

As for the other elements, wait for the nitrogen and sulfur results to come out.

"Then I wish you success."

"Let's hope everything goes well!" Li Xiang lifted his glasses and replied.

"By the way, Happy New Year!"

"Uh...... It's New Year's already?"

"......" Huang Haojie didn't know how to answer this question.

"See if you're free." Li Xiang opened the holographic bracelet to himself, and then looked at his schedule:

"On the 6th, we will do ...... Number 7 ......" he muttered as he flipped through the schedule.

"Forget it, just make a phone call and go back."

"Let's go home on Chinese New Year's Eve!" Huang Haojie couldn't stand it anymore.

This guy is so obsessed with research that he stays in the institute all day and doesn't usually go home, and even though his villa is less than three kilometers away from the institute, he only has a handful of days to go back all year round.

Fortunately, Li Xiang is not an only child, otherwise his parents would not be happy even if they lived in a villa.

A typical scientific research dead house is talking about people like Li Xiang, who has a laboratory where he can even be a man who doesn't need a woman.

"What day is Chinese New Year's Eve?"

"No. 4, the day after tomorrow." Huang Haojie replied helplessly.

"No, I have a ...... on the 4th"

"You're big! Everything is pushed back by one day, and you have to let go of this holiday! Otherwise, I'll ask Cheng'an to have someone tie you up." ”

Nima's! Every vacation has to be enforced, do you say it's easy for me?

watched Li Xiang reluctantly return to the laboratory.

He almost spurted out a mouthful of old blood, and everyone else wanted to have a holiday every day, but these guys were good, and they wanted to work overtime every day.

Of course, this has something to do with the scientific research system of Galaxy Technology, after all, those fruitful researchers are definitely the existence of the fifth king of diamonds.

Just like Li Xiang's more than one billion yuan a year is easy, or Dr. Yuan Quan of the Seawater Desalination Research Institute, with seawater desalination film and gold extraction film, he also has more than one billion yuan of income a year.

Although there are a few top researchers with this kind of income, even if it is an ordinary researcher, it is easy to earn a million dollars a year.

Moreover, their money is not deposited in the bank with interest, but is invested by the trust fund of Mars Group, and the annual growth rate is generally about 5~15%.

In addition, Galaxy Technology will reward or quota the dry shares of some of its companies to employees.

The employees of Galaxy Technology are all high-income groups, so in order not to lose this job, many employees work hard.

Researchers, on the other hand, are interested in royalties and shares.

……

Huang Haojie asked Zhong to inform the management committee of the institute and asked them to formulate a holiday and rest plan as soon as possible, so that some researchers would not be in the institute all day, if there were three longs and two shortcomings, it would not only be a loss, but also a trouble.

After arranging this matter, Huang Haojie came to the Hydrogen and Oxygen Engine Research Institute again.

Inside the mountain laboratory of the institute.

Huang Haojie and director Qin Tongxing were watching the test work of a rocket engine.

Boom Boom Boom ......

The light blue tail flame, even through the thick protective glass, can still feel the violence contained in the engine.

On the instrument on the side, Huang Haojie looked at the important parameters of the two rocket engines, specific impulse and thrust.

[Specific impulse: 372 seconds...... 377 seconds...... ］

[Thrust: 547 tons.] ］

Bichong is still beating.

Specific impulse is the momentum that can be generated per unit of fuel, that is, the combustion efficiency, which is generally known as whether it is burn-resistant or not.

And the greater the specific impulse of the rocket engine, the greater the load, which is applicable in any case.

The greater the thrust of the rocket engine, the greater the load, which is obvious in the first stage, less obvious in the second stage, and the impact of the third stage is very small.

Therefore, generally speaking, the first stage or booster is a kerosene and solid engine with large thrust and relatively small specific impulse, while the second and third stages generally choose a hydrogen-oxygen engine with small thrust and high specific impulse.

However, the hydrogen-oxygen engine does not necessarily have a small thrust, but the technology cannot meet the requirements of large thrust.
