After packing up the lab, I looked at the sky again, and it was still too late to find a scrap yard to dispose of the equipment.

So I took my mobile phone and found one on the Internet and asked them to come over now.

The business is large and expedited.

Then I packed up the leftover materials from the lab and moved them to the car.

After this time, I don't plan to come here.

Humming a little song, when the recyclers arrived, they cleaned up the lab again so as not to miss anything.

It didn't take long for the people who recycled the waste items to arrive, and there were quite a few.

Lu Yu beckoned them to go in and move the equipment, and they all looked at Lu Yu like fools.

All this equipment looks good, and now it's being sold as scrap?

They all wondered if these things belonged to Lu Yu after all.

It is not false to collect waste items, and they dare not collect things in irregular ways.

……

Lu Yu didn't explain much, and called the landlord in front of them.

After the phone was connected, Lu Yu said that he would not renew the lease in the future, and now he had to deal with the things in the house, but others didn't believe it, and he needed to take the real estate certificate to testify.

Fortunately, the landlord lives not far away, about ten minutes away.

After confirming the documents, the recyclers were relieved to move the equipment out.

Originally, the house was still some time to expire, and now it is not rented, and the landlord offers to move out the rent.

Lu Yu said that it would be troublesome for you to run at night, and suddenly it would not be rented, which would also affect the search for tenants, so there was no need to return.

The landlord was not polite and accepted with a smile.

……

After dealing with the equipment, the money to buy a device is not enough.

Lu Yu pursed his lips and looked at the time, it was almost midnight, so he drove back to Shi Zixuan and Qin Xiaomian.

By the time they got home, the two girls had gone to bed early.

It was already the second half of the night, so Lu Yu didn't bother the two girls, he went back to the bedroom softly, washed up before going to bed and getting ready for bed.

Lying in bed, tossing and turning and unable to sleep, probably yesterday I slept in the lab for a long time.

Lu Yu sighed, and simply took out his mobile phone to check the information of some basic materials and new materials.

……

As mentioned earlier, China is relatively backward in many basic materials, or even blank.

Today, China produces more than half of the world's steel, 60% of cement, and more than 25% of automobiles, making it the largest and most dynamic manufacturing center.

However, the domestic industry is big but not strong.

For example, the domestic hydraulic industry has become the second in the world, but 90% of the high-pressure piston pumps with a rated pressure of more than 35MPa rely on imports.

High-performance piston pumps, lighthouse country, Prussia, neon country and other four foreign leading enterprises occupy more than 70% of the domestic market.

In terms of technology, it is tightly sealed in the country.

It can be said that the high-pressure plunger pump is a thorn in the throat of China's equipment manufacturing industry.

It seems that this component is simple, but the high-pressure piston pump is the core component of high-end hydraulic equipment, which is called the heart of the hydraulic system.

The hydraulic system is one of the key parts of the equipment manufacturing industry.

Metallurgical industrial machinery, chemical industry, energy industry machinery, machine tool industry, construction industry machinery, as well as military, aerospace, shipbuilding and other fields, all need to be widely used.

……

For example, one of the important contributors to the success of the well-known large aircraft C919 test flight is the world's largest 80,000-ton die forging hydraulic press produced by Huaxia Erzhong.

It's just that the high-pressure piston pump is imported from the lighthouse country.

Dozens of plunger pumps rely on electric motors to pressurize the hydraulic oil and push the cylinders to generate 80,000 tons of forging pressure.

Another example is the crawler walking of the tank, which relies on the internal combustion engine to drive the hydraulic pump, so that the oil is controlled by the valve, and the output is output through the oil pipe, and the motor is driven into a rotary motion to drive the crawler to walk.

Some of the domestic tanks, armored vehicles and other military machinery are also imported high-pressure piston pumps.

And these imported hydraulic pumps, replacement and maintenance, will be limited by the supply cycle and service provided by foreign companies.

……

This is just the tip of the iceberg of basic materials and industrial backwardness.

The domestic material manufacturing industry, compared with the lighthouse country, is generally in a weak position, especially the manufacture of high-end materials.

In terms of traditional metal materials, there is also a big gap between us and Prussia and Neon Country, two traditional material powers.

But what is interesting is that in the past ten years, domestic researchers have published countless papers and articles in world-renowned academic journals in the field of materials such as AM, AFM, EES, JACS, etc.

According to statistics, in 2015, one out of every ten high-level English papers published by domestic researchers came from the field of materials science.

Since 2006, the number of papers published by domestic researchers in the field of materials science has greatly exceeded that of lighthouse countries.

Today, that number has nearly tripled.

Whether it is quantity or quality, I am afraid that it will make any country ashamed.

……

There is also a fun phenomenon.

On the one hand, the current level of the domestic material industry is still relatively poor, and it is the time when a large number of aspiring young people and talents are needed.

On the other hand, on the Internet forums where young students gathered, there were endless answers to persuade them to quit "pseudo-transformation".

The material discipline is the hardest hit area to retreat.

In fact, the reason for this phenomenon can also be traced, that is, behind the prosperity of materials research in China, there is no support for the corresponding volume of industrial applications.

In this case, the more materials and papers published by the university and the more talents it cultivates, the more severe the employment situation will be, and the worse the treatment will be.

This is closely related to the domestic discipline development idea of "emphasizing scientific research and ignoring application".

Under the idea of publishing more papers and publishing good papers, domestic researchers are more enthusiastic about researching novel materials.

These results are likely to be difficult to be applied in industry for decades.

Under the influence of the editor-in-chief of international academic journals, domestic materials researchers are enthusiastic about studying foreign academic hotspots.

On the contrary, it is difficult to publish high-quality English papers by studying traditional domestic materials that are urgently needed in China.

And even more money has been spent on scientific research.

……

This is almost the current situation of domestic materials science research.

However, although there are shortcomings and backwardness, there are also materials that are partly ahead and partly running together.

This part of the leading, almost all of them are new materials.

Because it is too advanced, it is generally not exposed, or embargoed to the outside world.

For example, the active stealth material "metamaterial" produced by domestic energy, according to foreign media, may be used in domestic stealth fighters in the future.

Another example is that because of the embargo, it took the lighthouse country more than ten years to break the domestic monopoly of "nonlinear optical crystals".

This KBBT crystal is the core material for quantum entanglement in quantum communication.

When the lighthouse country claimed to break the monopoly, China developed a new generation of deep ultraviolet NLO crystal materials.

……

The main thing that lags behind is traditional materials.

These traditional materials are not localized at all, or very little localized, and basically rely on anti-dumping investigations on imported products to survive.

Steel, chemicals, ceramics, polymer materials, etc., which are not so backward in some subdivisions, but due to backward technology, it is difficult to compare with them in terms of performance.

The production capacity is okay, but the performance is not enough.

And there is no localization at all, such as the chemical raw material "adiponitrile", which is the raw material for the synthesis of nylon double six.

Nylon Double Six is widely used as an engineering material that replaces steel, iron, copper and other metals with plastic.

Cast nylon widely replaces the wear-resistant parts of machinery and equipment, and is suitable for transmission structural parts, household appliance parts, automobile manufacturing parts, chemical machinery parts, etc.

Manufacture of turbines, gears, bearings, impellers, cranks, instrument panels, drive shafts, valves, blades, screws, high pressure washers, screws, nuts, seals, shuttles, sleeves, connectors, etc.

However, due to the difficulty of adiponitrile synthesis technology, it is still monopolized by the foreign chemical giant Solvay, and the price increase only needs to send an email.

The price of nylon double six in China has skyrocketed, and the fundamental reason is that adiponitrile is stuck in the neck of foreign countries.

Some domestic enterprises have also tried to produce adiponitrile.

Runxing Chemical Technology Co., Ltd. in Dongshan Province synthesized adiponitrile by acrylonitrile electrolytic dimerization, but unfortunately an explosion occurred in August 2015.

At that time, the Tianjin Port explosion incident was in full swing, and the voices of public opinion against the chemical plant were overwhelming, which directly led to the distant prospect of localization.

Another example is the traditional chemical material bisphenol A.

Some of the domestic localization has been made, but the technology is backward and the production capacity is small, so the product competitiveness is weak.

We have to rely on anti-dumping investigations on imported bisphenol A originating in neon countries, Singapore, stick countries, etc., in order to survive.

……

Lu Yu looked at this information and frowned.

Although modern industry is multi-party cooperation, the more high-tech and highly integrated products, the closer the international cooperation.

However, due to the different ideologies and systems of Western countries, domestic enterprises will be constrained in many cases.

It is also the norm for monopolies to lead to high prices.

Lu Yu flipped through his phone and fell asleep very late.

A bell interrupts the sound sleep.

Touching the phone with his eyes closed, he barely opened a gap in one eye and connected the phone: "Hey? ”

Chen Xiaofei's embarrassed voice came:

"The surname is Lu, you haven't gotten up yet?"

Lu Yu snorted in a daze.

Chen Xiaofei: "Did you forget today Saturday?" ”

Lu Yu was vague: "Zou Miao, what's wrong?" ”

Chen Xiaofei: "God is so difficult, Zhang Kexin said, today is her birthday, if you can't agree, she will barbecue in your living room." ”

Lu Yu barely sobered up a little: "Where are you barbecuing?" ”

Chen Xiaofei: "Your living room, on the edge of the small beach." ”

Lu Yu: "You don't care?" ”

Chen Xiaofei: "How can I control her, I'm thankful that she doesn't care about me." ”

Lu Yu sighed: "Hey, I didn't expect you to be a scumbag today, so I'll get up and tell her to let go of my living room, thank you!" ”

After saying that, I hung up the phone, still a little confused.

Lu Yu struggled to get up, thinking that the effect of this physique-enhancing drug was not obvious, and he was still sleepy when he slept a little later.

The interval between eating once a month is too long, and you have to eat it once every half a month.

Eat more and eat faster, Gan, and increase your mana!

……

After taking a hot shower, I came to my senses, found a set of casual pants in the closet and put them on, and walked out of the room.

Go downstairs and put on your shoes and go out to the parking lot to drive.

By the time I drove to Shuyin University, it was already an hour later.

On weekends, there is no limit to the number, and there are many special vehicles.

I found a place downstairs to park the car, walked upstairs, strengthened exercise, and took the elevator less.

When I entered the door, I found that there were already many people in the house, mostly girls, and there were also seven or eight boys.

As soon as Chen Xiaofei finished making a meal delivery call to a nearby hotel, he saw Lu Yu walk in and looked at Lu Yu's two hands:

"You're coming back empty-handed?"

Lu Yu was puzzled: "Do I have anything to bring when I go home?" ”

Chen Xiaofei looked at Zhang Kexin, who was playing with his friends.

Lu Yu understood in seconds: "But I'm really unprepared, I won't get up until you call me, or there is a bunch of experimental materials in the car downstairs, will it be a while?" ”

The corners of Chen Xiaofei's mouth twitched violently:

"Then I can't save you, ask for more blessings."

Lu Yu didn't pay much attention to it, just make up for it later, and looked at the people in the room again:

"Isn't it summer vacation? Why are there still so many people in school? ”

Chen Xiaofei: "Most of them are in the training camp of any musical instrument, and a few are staying in the study, don't think that others learn music and play every day." ”

Lu Yu said that he really thought so:

"Learn what? Playing and singing? ”

Chen Xiaofei looked like an idiot: "Do you think that learning music is learning a musical instrument?" Others also have behind-the-scenes, as well as film, television, and anime soundtracks. ”

Lu Yu nodded: "Then I really don't know, it's a loss." ”

Chen Xiaofei: "It's normal that you don't know, I didn't know before, it's the same as you, or I heard Zhang Kexin say it later." ”

……

Lu Yu was a little curious about his current state, and asked in a low voice:

"Eh, you and Zhang Kexin, do you feel like you're playing for real?"

Chen Xiaofei looked serious and whispered back:

"What is like, I mean it."

Lu Yu: "I've heard you say this more than once. ”

Chen Xiaofei was extremely serious: "This time I am really real. ”

Lu Yu smashed his mouth: "Tsk, look at you like this, you can't do it?" ”

Chen Xiaofei looked at Lu Yu sadly:

"Is this human speech? Am I for this? Shallow! Vulgar! ”

Lu Yu was unmoved: "Just tell me, do you have to do it or not?" ”

Chen Xiaofei's face was sad, a little gloomy and a little embarrassed:

"Once, there were many sincere opportunities in front of me, and I didn't cherish them, and I regretted them when I lost them......"

Lu Yu frowned: "Shouldn't it?" I remember the first time we went to the space bar, I sent shallow back to school that night, you took Zhang Kexin, you didn't have it? Don't? ”

After speaking, he also looked at Chen Xiaofei's next three roads suspiciously.

Chen Xiaofei had a look of great shame:

"Labor and management are no problem! Nine Jiro in one night! Hey, I saw that she drank too much that night, I didn't have a choice before, but I wanted to be a good person that night. ”

Lu Yu smiled unkindly: "What happened later? ”

Chen Xiaofei was also a little puzzled:

"The more I came into contact with it, the more I thought this girl was stupid."

"Can you imagine that when you were only thinking about how to sleep with her, she was full of joy and seriously fell in love with you."

"Not only stupid, but stupid and kind of cute! I have chosen to continue to be a good person several times, hey! ”

……

Lu Yu shook his head and didn't speak, saying that he didn't have this kind of experience and couldn't understand.

Chen Xiaofei was even more puzzled: "Are you saying I'm really true?" ”

Lu Yu thought for a while, and pointed to the handsome one among the boys:

"Let's put it this way, let's say he is chasing Zhang Kexin now, and Zhang Kexin is still a little excited, what should you do?"

Chen Xiaofei squinted at the boy, and then at Zhang Kexin.

Finally, he stared at the boy viciously:

"I'm spending money to find a few young ladies, serve him well, and let him die as much as he wants!"

Lu Yu stared at him incredulously:

"So ruthless? Chen Xiaofei, I really didn't find out before, you are a werewolf! ”

Chen Xiaofei: "This is obviously a good thing, so that he fully realizes his attractiveness." ”

Lu Yu: "Ness, is it okay to be kind?" ”
