Chapter 371: Teacher, are you looking for me?

In the afternoon, the drizzle rained up unconsciously. Compared with the summer rainstorm, the amount of rain is not much. It's just that the cold weather brought by the heavy rain in the late autumn season makes people shudder. Fortunately, Ye Qing prepared a lot of long coats for himself.

In the civil air defense project, Ye Qing and Master Qiao went through a long and wide passage into a large-scale equipment room that was clearly modernized.

The old steel cast explosion-proof doors here were transformed into automatic explosion-proof doors that need to be swiped into. Now the gate is open, and a sci-fi wind corridor leading to the red rear computer room appears in front of the two in a biohazard.

Master Qiao swiped the card into the glass door again, and blow the same air vortex of the blower on both sides and a synthetic electronic sound echoed in the corridor made of glass and metal. Of course, it was not a warning, nor is there a high-energy laser.

"Verified, please store the electronic products you carry with you in the electromagnetic shielding storage box and replace the dust-free clothing."

Two metal boxes popped up on both sides of the corridor to open a glass door of a dressing room with anti-static dust-free clothes of different sizes.

After putting the mobile phone and keys, Ye Qing went to the dressing room to change his clothes to a clean dust-free suit and stepped into this class 10,000 dust-free workroom that was even cleaner than the baby's skin.

This was the newly planned R & D department. This morning, the instruments ordered to the R & D department have just arrived and Ye Qing came here to visit. Any company that wants to maintain long-term product competitiveness must continuously invest massive amounts of money to develop new technologies and products.

There were products from Monster Heavy Factory in the new technology, and Ye Qing had an advantage that no company can match. But for new products and convenient functions, he had to do it himself.

To this end, Ye Qing ordered a batch of cutting-edge industrial experimental instruments that few people were willing to use. After not a long wait, this batch of cutting-edge industrial experimental instruments was officially settled in the new dust-free operations room of the Monster Heavy Industry.

A 10,000-class dust-free workroom referred to no more than 10,000 dust particles of 0.5 microns or more per cubic meter in the air. This sounded like a lot of numbers, but in the outdoor natural environment, even the beautiful grassland with clean air, the amount of particles per cubic meter was too much to be calculated by weight, and the quantity was not responsible for statistics.

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

The employees of the product R & D department, the technicians who are accompanying the instrument manufacturers, carefully studied the instruments debugging and daily maintenance steps.

The last recruitment, with the product development department, had the highest requirements for diplomas. Among the forty new employees currently joining this department, there are more than 20 with a master's degree and seven with a doctorate. One-quarter of them came from Ye Qing's alma mater, and the rest were also top students from major universities. These employees have been following the instructor to start the lab all year round. They have the strong hands-on ability and were very familiar with the various instruments in the laboratory.

The transmission electron scanning microscope has just been debugged. A master student who graduated from Shanghai University volunteered to drill into the enclosed ventilation operation room next door to observe the sample.

Observation samples of different microscopes have different observation methods. The sample of the projection electron scanning microscope, the ordinary optical microscope that is not in contact with the students, needed to be coated on the transparent glass sheet. It needed to be in the form of metal flakes. The master student followed the tutor before to study the technology of bainite steel.

Bainite steel is widely used in aviation, vehicles, ships, and materials for pressure vessels and high-pressure pipelines. To study bainite steel, the first step is to observe the characteristics of bainite steel.

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

When Ye Qing entered, the employee was in the ventilated operating room, dipped in the abrasive liquid with an eraser and wiped back and forth mechanically on a stamped metal sheet that was barely visible to the naked eye.

"Boss..." The employee stopped wiping and stood up to say hello to Ye Qing somewhat restrained.

Because no suitable person was found, for the time being, Ye Qing was temporarily the manager of the product development department. Ye Qing gave them a meeting before, so the new employees here can recognize him.

"Tang Bo, do you... plan to use an eraser to wipe the sample to a thickness of 500 nanometers?" Ye Qing also had a picture of the senior from his alma mater. Seeing this, his eyes widened.

That's right! The sample thickness of the electron scanning microscope is only a few hundred nanometers. This thickness is roughly equivalent to one-thousandth of a hair strand, and only those special and often only responsible machine tools for one process can cut it.

"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 is taught by my brother. He said that the sample slices are processed with high-precision machine tools, and the metals wear each other, so it is easy to participate. Other metals go in and affect the observation effect."

"With manual polishing, as long as you master the correct method, the time will not be slower than that of the machine tool. And the sample produced has only a single and very conducive bainite structure to observation."

Ye Qing gave him a thumbs-up, gesturing him to continue his efforts.

By hand grinding, it is indeed possible to slowly grind the metal sheet to that thickness. The eraser only grinds on a large piece of metal foil. Finally, cut out the appropriate sample shape under an optical microscope.

There are extremely advanced laser thickness gauges to check the thickness continuously. As long as you have patience, in theory, ordinary people can also grind out a thickness of 500 nanometers. It doesn't matter if it's worn out, the sample only needs a small 3 mm long disc, and you can cut a piece from there.

Of course, this is just a theory, not to mention 500 nanometers for ordinary people 50,000 nanometers will have to develop mania.

Looking at Tang Bo, Ye Qing was very happy. He realized he had recruited talents, a talent with extraordinary patience.

"Boss, the instruments here are so advanced that you even have atomic probes. It's like the Eden of the industrial god. Only the chemical laboratory at Shanghai University can handle it. If our industrial god wants to do an electrical scanning, it depends on the face of the chemical laboratory. As for the obsolete products that were ten years ago, compare it to yours, the gap between the pheasant and the phoenix. As for the atomic probe, I guess only those professors have seen it."

"Then work hard. As long as you can purchase any equipment, the price is never a problem."

Ye Qing encouraged him by a few words and turned to visit other places.

Ye Qing just walked in front of the isotope mass spectrometer, over the dust channel and came in a man wearing a dust-free suit and shouting: "Boss... Boss.".

The visitor was Kong Tao, the sales manager. After seeing Ye Qing, he trotted over and said: "Boss, I just couldn't make a call to you. Cai Chenning of Shanghai University called and said he would like to ask you for a favor. He introduced himself as your university teacher, and I rushed to find you here."

"Well, he is really my teacher." Ye Qing nodded, went to the dust removal channel, took out the phone and dialed Professor Cai Chenning number.

"Teacher, are you looking for me?"
