In the afternoon, the drizzle unconsciously began to fall again. Pen, fun, pavilion www. biquge。 info

Compared to the midsummer rainstorms, this amount of rain is nothing. It's just that in late autumn, the cold brought by the heavy rain makes people shiver constantly.

Fortunately, Ye Qing prepared a lot of long clothes for himself, and he didn't feel cold at this time.

In the civil air defense project, Ye Qing and the delicate master walked through the long and wide passage and walked into a large equipment room that was bright and obviously modernized.

The old steel-cast blast doors here have been transformed into automatic blast doors that require swiping to enter. Now that the door is open, a sci-fi corridor leading to the Red Queen computer room as if in Resident Evil has appeared in front of the two.

Swipe the card again to enter the glass door, and blow a blower-like air vortex on both sides. A synthetic electronic sound echoes through the hallway of glass and metal.

Of course it wasn't a warning, and there was no high-energy laser sweeping over.

"After verification, please store the electronic products you carry with you in the electromagnetic shielding storage box and change into dust-free clothes. ”

Two metal boxes popped up on both sides of the hallway, opening a glass door to a locker room filled with anti-static dust-free clothes of different sizes.

After putting away his mobile phone and keys, and going to the locker room to change into a well-fitting dust-free suit, Ye Qing stepped into this 10,000-level dust-free workshop that was cleaner than a baby's skin.

This is the newly planned product R&D department, this morning, the instrument ordered by the R&D department has just arrived, Ye Qing came here to visit.

Any enterprise that wants to maintain long-term product competitiveness must continuously invest a large amount of money in the research and development of new technologies and new products.

There are monster factories, and in terms of new technologies, Ye Qing has an advantage that no other company can match. However, in terms of new products and convenient features, you have to do it yourself.

To this end, Ye Qing ordered a batch of cutting-edge industrial experimental instruments that few people are willing to use, and after a not too long wait, these cutting-edge industrial experimental instruments were officially settled in the new dust-free operation room of Giant Beast Heavy Industry.

Class 10,000 dust-free workshop refers to the dust particles greater than or equal to 0.5 microns per cubic meter in the air, not exceeding 10,000.

This may sound like a lot, but in the outdoor natural environment, even in the beautiful grassland with clean air, the amount of particles per square meter is so large that it can only be calculated by weight, and the number is not responsible for statistics.

Walking here, Ye Qing was like walking into a white pure world.

The equipment is pure white, the ceiling is pure white, the walls are also pure white, only the floor, which is different from the dust clothing on the employees.

Transmission electron scanning microscope, thermomechanical analyzer, material stress detector, isotope mass spectrometer......

The employees of the product R&D department are accompanying the technicians sent by the instrument manufacturer to carefully study the debugging and daily maintenance steps of the instrument.

In the last recruitment, the product research and development department had the highest requirements for a diploma.

At present, among the 40 new employees who have joined this department, there are more than 20 people with master's degrees and 7 with doctors. A quarter of them are from Ye Qing's alma mater, and the rest are also top students from major universities.

These employees have been working in the laboratory behind their mentors all the year round, not to mention their hands-on ability, and they are very familiar with various instruments in the laboratory.

No, the transmission electron scanning microscope has just been commissioned. A master's student who graduated from Zhongyun University volunteered to drill into the closed ventilation operation room next door to polish the sample.

Different microscopes have different ways to observe specimens.

Specimens of projected electron scanning microscopes, ordinary optical microscopes that students do not come into contact with, need to be coated with a layer of translucent glass, which needs to be in the form of metal sheets.

The master's student had been following his mentor to study the process of bainite steel.

Bainite steels are widely used in aviation, vehicles, ships, as well as pressure vessels and high-pressure pipelines, and the first step in studying bainite steels is to observe the characterization of bainite steels.

Characterization is commonly known as the amplification structure, from its appearance to the magnification of the crystal structure, so that the naked eye can observe the crystal pattern of bainite.

When Ye Qing entered, the employee was in the ventilated operation room, using an eraser to dip the slurry and mechanically wiping it back and forth on a thin sheet of stamped metal that was almost invisible to the naked eye.

"Boss~" The employee stopped wiping, stood up and greeted Ye Qing with some restraint.

Because no suitable candidate was found for the time being, Ye Qing temporarily served as the manager of the product research and development department. Ye Qing had a meeting with them before, so the new employees here could recognize Ye Qing.

"Tang Bo, you...... Are you going to rely on an eraser to rub the sample to a thickness of 500 nanometers?" Ye Qing also had an image of this senior from his alma mater. Seeing this, my eyes widened.

That's right!

The thickness of the specimen in the electron scanning microscope is only a few hundred nanometers.

This thickness is about one-thousandth of a human hair, and can only be cut by special machine tools, which are often responsible for only one process.

"Grind out an approximate thickness, and then use a laser thickness gauge to detect it at any time. Tang Bo scratched his head: "This method was taught by my senior brother, he said that the sample thin slice is processed with high-precision machine tools, and the metals wear each other, and it is easy to enter other metals, which affects the observation effect." ”

"With manual grinding, as long as you master the right method, the time is not slower than that of a machine tool. And the specimen produced has only a single bainite structure, which is very easy to observe. ”

Ye Qing gave him a praising thumbs up and motioned for him to continue working hard.

Hand sanding, it is indeed possible to slowly grind the metal sheet to that thickness. The eraser grinds only a large sheet of metal, and finally cuts out the appropriate specimen shape under an optical microscope.

There is an extremely advanced laser thickness gauge to constantly detect the thickness, as long as there is patience, theoretically ordinary people can grind out 500 nanometers thick. It doesn't matter if it's worn, the specimen is only 3 mm long and a small piece can be cut from anywhere.

Of course, this is just a theory, and ordinary people have to grind out mania at 500 nanometers, not to mention 500 nanometers.

Seeing that Tang Bo was very happy, Ye Qing realized that he had recruited a talent, a talent with extraordinary patience.

"Boss, your instruments here are so advanced that you even have atomic probes. Tang Bo became more and more energetic: "This is like the Eden of industrial dogs, only the chemistry laboratory in Zhongyun University can handle it, and if we industrial dogs want to do an electrical scan characterization, we have to look at the face of the chemical laboratory." ”

"As for the eliminated products ten years ago, compare with you, the boss, the gap between the pheasant and the phoenix. As for the atomic probe, I guess only those professors have seen it. ”

"Then do a good job, any equipment and instruments, as long as they can be purchased, the price is never a problem. ”

With a few words of encouragement, Ye Qing turned around and went to visit other places.

As soon as Ye Qing walked in front of the isotope mass spectrometer, on the side of the dust removal channel, a person wearing a dust-free suit walked in and kept shouting: "Boss ~ Boss".

The person who came was Kong Tao, the sales manager, and after seeing Ye Qing, he trotted over: "Boss, I can't get through to your phone just now." Cai Chenning from Zhongyun University called and said he wanted to ask you for a favor. ”

"He introduced him as your university teacher, so I hurried here to find you. ”

"Hmm~ He is indeed my teacher. Ye Qing nodded, walked to the dust removal channel, took out the phone, and dialed Professor Cai Chenning's phone.

"Teacher, are you looking for me?" )
