Black Technology Refresher Manual

When Heijin Technology and Niu Ruizhi became famous in the field of material physics, Sheng Ming'an's team was completely immersed in the busy experimental data collection, without any awareness of it.

In the past three months, the laboratory has collected a huge amount of data and images, enough for the project to enter the next stage of modeling and simulation.

On this day, Lu Yin, Sun Cheng and Fang Zuo arrived at the laboratory on time.

Sheng Mingan turned to look at them: "Jiao Yuguo didn't come?"

Lu Yin and Sun Cheng looked at Fang Zuo, who said, "He quit."

Lu Yin was surprised: "Jiao Yuguo found a better next home than our laboratory?"

The wages, allowances and benefits offered by Sheng Mingan exceeded more than half of the domestic laboratories, otherwise Jiao Yuguo, who was full of complaints, would not work honestly for three or four months.

Now that he ran away, he probably found a better next home. Lu Yin was curious about which one.

Fang Zuo: "Black Gold Technology."

Lu Yin: "Heijin Technology's welfare system is better, but the pressure? It's twice as much as ours."

Fang Zuo: "Is there a black gold technology? Professor Niu, he is a leader in the research and development of graphene materials in China. Some time ago, he published a paper on the large-scale preparation of graphene, and proposed a new method, which is regarded as the most promising by the material physics community. A technical solution to realize graphene freedom."

Sheng Mingan became a little interested when he heard the words: "What is the plan?"

Fang Zuo: "Macroscopic preparation of graphene by magnetically dispersed arc plasma."

"..." Sheng Mingan fell into a strange silence.

Lu Yin's expression was also a bit weird, but Sun Cheng said in surprise, "Isn't it colliding with our experimental thinking?"

Fang Zuo: "Yes. Jiao Yuguo blurted it out, and I too? Only then? Knowing that he is interested in the development potential of the black gold technology project? So he quit. Shenggong, do we need to call the police? What if Jiao Yuguo leaked our experimental data?"

Sheng Mingan shook his head: "No need to call the police."

Sun Cheng was annoyed: "Just let Jiao Yuguo take our experimental data and go to Niu Ruizhi? Obviously Niu Ruizhi stole the plan in Shenggong's draft book, adapted it, and submitted it for publication to become his SCI work. Don't you worry that Niu Ruizhi will use Jiao Yuguo? Bring the data improvement plan, overcome the technology in advance, and occupy the results?"

Not to mention Fang Zuoduo? He was so shocked that Niu Ruizhi, who he thought was a master of materials physics, actually stole Sheng Mingan's proposal. Lu Yin also expressed some concern: "After all, he is a popular candidate for the selection of national academicians, so Niu Ruizhi should not be underestimated. If ?What did he see from the data brought by Jiao Yuguo? With the ability of his team, he published the results before us? It's not impossible."

Sheng Mingan smiled at them, still calm and calm: "Niu Ruizhi can't guess. Don't worry, don't worry about them too much."

Seeing that Sheng Ming'an didn't say the reason, and his tone was firm, Lu Yin and the others were dubious, but they could only choose to follow his arrangement and prepare for the next stage of the project, which is to conduct two-dimensional numerical simulation on the magnetic arc plasma.

Sheng Mingan opened the software FLUENT, which is a commercial software with advanced numerical values ​​and rich physical models. This software can be applied to aerospace design, turbine design, etc., and he has developed a set of calculation programs using the software before.

The calculation program can simulate the heat transfer and flow of the thermal arc. Next, the two-dimensional numerical simulation of the magnetic arc plasma under different conditions is established in this set of calculation programs of the software.

Sun Cheng didn't quite understand, Fang Zuo showed a thoughtful expression as Sheng Ming'an's operation gradually deepened.

Lu Yin guessed that he probably saw it, thinking that Fang Zuo usually looks dull, but he is actually smarter than Jiao Yuguo.

Sheng Mingan called up the collected pictures and collected data, browsed the past ten lines at a glance, and quickly called up the data he needed from thousands of data and dazzling pictures.

A picture flashed across the display screen. The picture installation was in the shape of a round table, inlaid with countless circuits and square iron blocks. At first glance, it looked like a row upon row of cities.There is another picture parallel to it, with a thick black background and a smoky white cloud.

The previous photo is the multi-electrode arc test device, and the latter photo is the discharge picture of the device.

Fang Zuo remembered that the two pictures were data collected by him. There are many kinds of arc discharge devices. Sheng Mingan asked the team to test all the arc discharge devices one by one and collect data, from which they analyzed the technical shortcomings and advantages involved in the devices.

Seeing the data flying past before Sheng Mingan's eyes but not being used by Sheng Mingan, Fang Zuo couldn't help asking: "Sheng Gong, are these data useless?"

They have been busy for three or four months. If the collected data is useless, why does Sheng Mingan let them keep experimenting?

Sheng Ming'an: "It's useless." After a pause, he explained: "These arc methods are to obtain large-volume plasma through discharge, but they have not fundamentally solved the problem of arc plasma uniformity. We need to find out A technique that would address or weaken the self-contraction effect of the thermal arc itself, I just wanted to line up the appropriate magnetic field based on the data."

"The magnetic field and the current affect each other. After understanding the magnetic field, I can design an external magnetic field to control the distribution of the current, thereby affecting the heat transfer and flow of the arc."

It is equal to controlling the flow of plasma and obtaining the dreamed uniformly distributed plasma.

Fang Zuo fell into deep thought while listening to Sheng Mingan's explanation, and suddenly realized after a while: "I see—it's a device!!"

Sheng Mingan lowered his eyes and continued to operate.Lu Yin smiled.Sun Cheng asked blankly, "Fang Zuo, what do you understand?"What device?Did you say arc device? '

Fang Zuo looked excited: "Develop a magnetic arc to generate a large-volume, uniformly distributed plasma device, and obtain plasma by controlling the magnetic field to affect the flow of the arc discharge. Under the control of the data set in advance, what volume and how accurately do you want?" The evenly distributed plasma reacts inside a device, turning the difficult-to-control plasma into artificially controllable!"

Sun Cheng was still a little confused: "What?"

Fang Zuo took a deep breath, calmed down his excitement and said, "To put it simply, directly manipulate the plasma to synthesize graphene. The restriction of graphene preparation is stability, graphene is not stable enough, and technology restricts the production of large-area graphene However, now there is a device that can achieve stable and large-area graphene plasma synthesis, and if the device is optimized, industrial production of graphene is no longer just a concept.”

To put it simply, once Sheng Mingan designs the device, passes the acceptance test, and puts it into use, industrial graphene production is only a matter of time.

Sun Cheng took a deep breath: "Damn it, I knelt down to Gong Sheng."

Sheng Mingan: "Don't kneel too early, wait for the simulation to pass."

Fang Zuo, who had already understood the final plan of the experiment, stepped forward one after another and stood beside Sheng Mingan to help him extract the data.

Sheng Mingan called Lu Yin and the others to come here because he trusted them, so he didn't hide his secrets, and when he encountered some difficulties, he took the initiative to say: "The discharge process produces a high-temperature burn device, but have you seen these experimental research data? "

Pointing to the data flashing on the screen with the mouse, Sheng Mingan said, "Sun Cheng, I remember that this is the project you are in charge of."

Sun Cheng straightened his back: "Yes."

Sheng Mingan: "What do you see from the research?"

Sun Cheng: "The increase of arc root rotation speed can reduce electrode loss and improve electrode life."

Sheng Ming'an: "According to this sentence, the experimental design and measurement were carried out, and the burning rate of the copper electrode was calculated to be approximately inversely proportional to the rotation speed of the nitrogen arc."

"!" Fang Zuo quickly wrote it down, this is a very important conclusion.

Sun Cheng opened his mouth slightly, he didn't expect that his research conclusion could derive other data equations.

"The rotation speed of the arc is one of the key factors affecting the arc. It can be calculated from the empirical formula obtained from previous scientific research data..."

Sheng Mingan spoke slowly, using the most simple and easy-to-understand words to describe the ideas, data, formulas and conclusions of the experiment. He was good at using vivid metaphors, which made it easy to understand and understand.

The boring experiments repeated every day for three or four months, the content of the experiments that are not repeated, or the classic experimental cases that replicate the history of graphene research in the physics world, or the assignment of topics to be designed, cooperated, and manufactured by the team, all the data obtained are now available. Save it in the hard disk under Sheng Mingan's palm.

After solving the data allocation, it is the design of the experimental device, and the structure of the plasma generator is analyzed, including the plasma generator, power supply, water cooling unit, arc current and voltage data acquisition unit, high-speed CCD photography, area array ICCD photography unit, etc.

The first is the design of the plasma generator.

"The generator is composed of a graphite anode and a cathode. The anode is tubular and the cathode is rod-shaped. Radial air intake is used to reduce electrode ablation..."

The cross-section and frontal structural design drawings of the generator appeared in the software, and then the design of the test device continued according to the magnetic field strength distribution. Each unit structure was established and formed little by little under the witness of several people.

Time passed bit by bit, from morning to noon, to afternoon, the sun went down, night fell, the lights in the laboratory were on, no one moved, until they were hungry and had to stop the progress.

Sheng Ming'an announced that he would continue tomorrow and go back to rest first.

He is tired too.

He hadn't eaten or rested all day, consuming his brain power crazily? Once he left the laboratory, he was overwhelmed with exhaustion like a mountain.

After returning to the room, Sheng Mingan simply ate something to fill his stomach and fell into a deep sleep. He didn't even reply to Chen Jingqiu's message.

After waking up the next day, after freshening up, Sheng Mingan was sober-minded. He took the reply to Chen Jingqiu's message and walked towards the laboratory. As soon as he arrived at the door, he saw Lu Yin and the three of them.

The three of them arrived earlier than him, and when they saw Sheng Mingan, they greeted Sheng Mingan together: "Sheng Gong."

They look forward to the finished product more than Sheng Mingan.

Sheng Ming'an doesn't talk much? Say, continue the design of simulation modeling.

Another day passed, and there were many mistakes, but they were kept within a controllable range, and they always maintained a high-intensity workload, and it was not until the fourth day that the final model was ushered in.

The huge laboratory was empty, with only four figures standing in front of each device and staring at the model data being established in the software.

Sometimes they will shuttle back and forth between various devices, taking notes from time to time with notebooks and ballpoint pens in their hands.

At this time, the display screen in front of Sheng Ming'an synthesized a model of the magnetron arc device.

Fang Zuo stopped and stared at the display screen in front of Sheng Mingan with piercing eyes.Lu Yin stepped forward quickly, followed by Sun Cheng.

Although the model is established, it cannot be regarded as successful. It is necessary to simulate the experiment in the model, and it is considered successful if it matches the calculated value.

According to the assumptions of the numerical model, the calculation domain, the control equation, etc., the values ​​are calculated and input into the model for simulation to control the temperature, velocity, atmospheric pressure, and current density distribution of the magnetron arc plasma, and to control the external magnetic field...

Step by step, Sheng Mingan completed the test in an orderly manner and obtained a graph that conformed to the result.

The graphics almost overlap with their previous calculations, the data is similar, and the error is not big.

The three people on Fang Zuo slowed down their breathing, for fear of disturbing Sheng Mingan and interrupting his train of thought.

The flickering curves of the display screen depict extremely beautiful mathematical graphics. These graphics look inconspicuous, quietly appearing on the screen, disappearing silently, and hiding in the hard disk, as if they have no effect.

In fact, they are full of power, comparable to thunder and tsunamis.

Once they are tested and applied to actual devices, graphene can be easily prepared, completing the industrial preparation of graphene, promoting the birth of new materials, and ushering in a material revolution for the world.

At the last moment, the display suddenly shuts off and plunges into darkness.

The laboratory was so quiet that only the beeping of the device remained.

Fang Zuo swallowed, his throat was dry and anxious: "Sheng Gong, did the model test pass?"

The moment the computer screen went black, Sheng Mingan's mind flashed the familiar mechanical voice of the black technology program: [Congratulations to the host for completing the initial stage of graphene industrialization. 】

For a moment, his mind went blank, Sheng Mingan couldn't perceive his own existence, couldn't hear Fang Zuo and others' inquiries, flashed in his mind, "The launch time of the black technology program is too fast this time", "It seems that the model test was successful", " initial stage?The model test is the initial stage, the manufactured device should be the middle stage, and the highest stage is estimated to be the graphene material revolution'.

"Sheng Gong? Sheng Gong!"

Sheng Mingan came back to his senses, lowered his eyes, withdrew his hand resting on the keyboard, looked up at the reflection of the team on the display screen and said: "Download the relevant information on patent registration first, but this time we have to apply for international patent registration. By the way— —”

"I don't mind if you use the previous experimental data as papers, but it's better to wait until the patent is issued. Finally, congratulations to our laboratory for completing the initial stage of the graphene industrial production project."

"—"

There was silence, then screams, cheers and hugs.

Although scientific research is a arduous and boring path destined to practice alone, the joy at the moment when the fruit of success is plucked will never change.
