Black Technology Refresher Manual

Sheng Ming'an has been an intern under Professor Pan for four months. He combines study and work every day, isn't he? He is staring at the data or running the data. boring.

But he's enjoying it, no? Like other graduate students complaining.

In his spare time, Sheng Ming'an would chat with Chen Jingqiu on social software. Most of the time, he would not find the same free time, but no matter how late it was, they would reply to each other's messages.

Did Sheng Mingan get used to this method of contact at first? It was Chen Jingqiu who took the initiative and persisted for more than half a month, and he gradually got used to it.

At noon this day, Sheng Mingan, who was staring at the data of the quantum simulation project in the laboratory, suddenly heard the "ding dong" sound of the long-lost black technology program going online: [Congratulations to the host for completing the achievement of "study success", unlocking the black The third level of the technology program and its rewards. 】

[Tips for the third level: Please prove the existence of one of the most powerful candidate particles for dark matter, the axion! 】

[Reward: 'Material Revolution - Industrial Use of Graphene', Numerical Simulation of Magnetically Dispersed Arc Plasma. 】

[Congratulations to the host for completing the checkpoint and climbing the academic peak. Don’t be afraid of hardships and dangers, respect science and physics. 】

Closing words changed?Sheng Mingan raised his eyebrows, wasn't it? It was a simple sentence before, 'please the host actively complete the level', but a more sincere blessing.

"Shengshen, I'm here to change shifts." Behind him, a graduate student from the same period knocked on the door and said.

Sheng Mingan nodded, and after explaining a few words about the progress of the experiment, the use of scientific research equipment, and the changes in the currently recorded data, he packed up the drafts on the desktop and the phone to prepare to leave.

The graduate student at the same time glanced at his mobile phone whose page was still on, and joked casually: "Chat with your girlfriend?"

"What??" Sheng Mingan looked up and saw him looking at the mobile phone chat page on his draft book, so he turned off the screen and replied, "Just chatting with friends."

During the same period, graduate students have seen the contact person at the top of the chat interface call 'Brother', holding a mobile phone every day and posting like a diary. Except for scientific research, they only become lively when they receive replies, and they call 'Brother' , And? Said to be friends, adults understand everything.

"I understand." The graduate student at the same period made an 'ok' gesture and said: "It's about privacy, I won't say it everywhere."

She just didn't expect? Sheng Ming'an's sexual orientation would be male.

By the way, who is so awesome to take down Shengshen?

If you know each other, maybe you can learn from it.

The strange expression of the graduate student at the same period made Sheng Mingan feel uncomfortable. He shook his head and went to the pantry to wait for the takeaway, recalling the level prompts and rewards of the black technology program while walking.

When unlocking the third level, the black technology program gave him a reward and a level, all of which are general and broad topics, and he needs to complete the halo achievements such as "study" and "career" step by step.

'Academic success?' should refer to graduation.

However, it has been seven or eight months since he got his graduation certificate. The black technology program judged that the halo achievement has been achieved. I don’t know what changes have occurred in the influencing factors of customs clearance, which caused the delay of half a year.

Sheng Mingan took two sips of black coffee, and the bitter taste quickly spread on the tip of his tongue, which successfully had a refreshing effect, but it also made him frown uncontrollably.

In the past, drinking two big cups of bitter black coffee could not change the color of the noodles, but now I can't stand it anymore after two sips.

Sheng Mingan thinks that the reason why he has become so used to black coffee is that he joined Blue River Technology to develop lithography machines last year. For more than a year, under the subtle influence of Chen Jingqiu, he changed from drinking black coffee on an empty stomach every day. The habit of drinking coffee is replaced by strong tea to refresh the mind.

There is only a coffee machine in the pantry in the laboratory. I drank all the tea leaves a few days ago, leaving only some scented teas that have no refreshing effect.

Sheng Mingan poured out the coffee and placed an order for green tea, thinking that if Chen Jingxiu was around, he would definitely brew the tea in advance and place it around his workplace.

Withdrawing his divergent thoughts, Sheng Ming'an focused on the checkpoints of the black technology program and the so-called 'rewards', first of all, the candidate particles of dark matter.

Dark matter is an invisible matter that may exist in the universe in physical theory, and is the main component of the universe. The concept of 'dark matter' was first proposed by astronomer Kaptan in 1922. Afterwards, it was indirectly demonstrated by physicists with various experiments, but it could not be directly proved, observed and captured.

In the 20s, particle physicists developed the standard model of particles, which well described the three forces (strong force, weak force and electromagnetic force) of the known elementary particles and their constituent substances, but neutrons However, the quark has a charge inside, and the charge is affected by some unknown reason and presents a state of uniform distribution.

The Standard Model cannot explain this phenomenon.

So some physicists made the hypothesis that there is a hitherto unknown magnetic field inside the particle that permeates the space and suppresses the asymmetry of the neutrons. Based on this conjecture, the standard model of particles is adjusted to allow the existence of the magnetic field, and then we get The theory that there exists a new particle.

The new particle was named the axion.

Axions weigh almost ?, are currently unobservable, but are infinitely numerous.

People realize that the existence of axions can be used to explain nearly 85% of the mass of the universe that is missing in the standard model of the universe. If the existence of axions is proved, it can explain the source of dark matter and the main composition of matter in the universe Element.

To put it simply, people compare the standard model of the universe by explaining the fundamental force and matter composition inside the particle, and infer the dark matter in the universe by assuming a certain magnetic field and a certain new particle inside the particle.

Because the forces in both the microcosmic and macrocosmic worlds are similar, the standard models established by each other can communicate with each other.

Theoretically speaking, axions must exist, but this hypothetical particle is only 'possibly' one of the potential particles that make up dark matter!

So? The black technology program said 'one of the most powerful candidate particles for dark matter' instead of 'dark matter particles', which is an affirmative answer, really damn rigorous!

At present, countries all over the world are building corresponding dark matter particle detection devices. The dampe (dark matter particle detection) launched by Huaguo in 15 years, maybe it’s not like that? Yes, the Chinese name ‘Wukong’ should be familiar.

Secondly, the "Panda Project" experimental detector in the deepest basement in the world was upgraded last year, and it is also a large-scale mechanical device for exploring dark matter.

Abroad, there are also the European Large Hadron Collider, the new detector Xenon1t, which is jointly cooperated by international multinationals, and so on.

The above are the ways to search for dark matter with different devices and different methods, and the existence of 'axions' can undoubtedly be proved by the alps device of Germany and the cast device of CERN (the most sensitive axion telescope in the world) Helioscope), or the axion halo telescope of domestic "Panda Project" experimental detection.

Unless one personally participates in these scientific research large-scale engineering projects and is able to control large-scale scientific research devices, it is absolutely impossible to capture the 'axion' with literature and software simulation alone.

This level is really difficult!

Sheng Ming'an put it aside for a while, and turned to look at the material revolution below, the numerical simulation of magnetically dispersed arc plasma?

Does this have any direct connection with graphene extraction technology?Or is there any direct effect?

Black technology program will not always give him useless tips.

Sheng Ming'an thought about it, and fell into a brainstorming process. From the method of preparing graphene by plasma process, he thought of several existing technologies.

Radio frequency induction heating plasma and microwave heating plasma are technologies for pyrolyzing hydrocarbons to synthesize graphene, but the energy consumption is too high, the product uniformity is low and the stability is insufficient, and there are very obvious technical bottlenecks. Can not achieve large-scale industrial production of graphene.

"Magnetically dispersed arc plasma?" Sheng Mingan muttered to himself: "The thermal plasma technology, because the electrical conductivity of the plasma increases with the temperature, the arc automatically shrinks, requiring graphene to be synthesized in an instant..."

Large-area balanced heating is difficult to accurately control, which ultimately leads to insufficient performance of the finished product.

In order to achieve low-cost and large-scale production, the technical defects of poor product uniformity and high energy consumption must be solved.

But no matter which technology is mainly related to the principle of thermal plasma, the use of thermal plasma conditions at high temperatures to achieve complex processes.

One of the most common ways to realize thermal plasma is arc thermal plasma.

However, in the dispersed state of thermal plasma, the condition of large area and uniform density distribution must be achieved, which is also a technical problem that needs to be solved urgently.

To put it simply, the use of thermal plasma technology to synthesize graphene is one of the ways to obtain graphene, and by solving the problems of instability and non-uniformity in the thermal plasma arc dispersion state, it is to achieve high quality and low cost. , One of the important ways to industrialize the production of graphene.

So the question is, how to realize the technical defects of arc thermionic body?

The draft book has drawn a complete tree diagram, and Sheng Mingan's gaze returned to the original "magnetic dispersed arc plasma" in the tree trunk, guessing that this might be the hint to solve the problem.

At this time, the food was sold out, so Sheng Mingan put away his drafts, finished his lunch, and returned to his laboratory to continue his original work.

The scientific research project assigned by him is the preparation and observation experiment of light quantum entanglement state, which is in the process of coming to an end.

Quantum entanglement of light is a national scientific research project under the charge of Professor Pan. The large-scale project has spawned dozens of small projects, and the team led by Sheng Ming'an was assigned to one of them.

Quantum entanglement of light is known as ghostly action at a distance. The principle is that after two photons from the same beam of light are separated, no matter what behavior one of the photons does, the other photon will do exactly the same behavior even if it is far away at the end of the universe.

Physicists have not been able to explain the quantum entanglement of light so far, and have classified it into quantum mechanics and studied optical communication technology through this theory.

In the experiment, the photon contrast is measured by a semiconductor blue laser, and the Bell's inequality is verified by this measurement method.

The graduate student in the same period was a girl named Li Nan.

When Li Nan saw him coming, she took the initiative to get out of the way, and at the same time handed over her data records within an hour at noon and the data recorded by Sheng Mingan in the morning: "The focus and optical path adjustment of the laser are based on the data set in the previous simulation. Once set up, the direction of the crystal axis is adjusted to be vertical, and the obtained interference fringes are as follows—”

She called up the screenshots from the computer archives, and neat white stripes appeared on the black pictures.

"But the calculated data is not right. I can't find the problem."

"Let me see."

Sheng Ming'an took Li Nan's draft, read it twice combined with the interference diagram, and finally noticed something unusual: "The degree of entanglement is a little low."

"Really?" Li Nan leaned over to look in surprise, in his heart? After some calculations, he said in disbelief: "It's here? Something went wrong?! Then what should we do now?"

Sheng Ming'an pondered, and said: "Where is the light path converted? Add the main and auxiliary crystals to compensate for the photons that walk away."

Li Nan pondered for a moment following his suggestion, his eyes glowed: "Exquisite!"

The general direction and steps of the experiment are correct. The problem is that it is easy to overlook some minor problems. It requires full patience, care, overall planning, and insight into the mistakes and omissions of each step.

In short, in one sentence, physics is a rigorous subject.

Sheng Mingan looked around the laboratory, but didn't see another figure who should have stayed in the laboratory: "Where's Zhang Chaoren?"

Li Nan curled her lips: "I asked for sick leave again this morning."

Sheng Ming'an raised his eyebrows. There are three people in his team. Li Nan and Zhang Chao are both members of his team. It has been three or four weeks since everyone joined together for a project.

When he asked Zhang Chao if he could easily complete single-mode optical fiber collection, and Zhang Chao was at a loss for the name, Sheng Mingan knew that this was a successful researcher who relied on research and various bonus competitions at the university. Or speculators who take the postgraduate entrance examination, can they rely on scientific research?

However, Zhang Chao was quite diligent when he started working in the lab and running errands. Until the last week, when the project was coming to an end, the lab could hardly find him.

At first, I was late, and then I was absent from work for half a day, either because I was sick or asked for leave or something happened at home.Today is even more exaggerated, and I directly asked for a day off.

Li Nan shrugged: "Anyway, it's a group project. Now that the project is over, he doesn't have to worry about being replaced. Of course, he can just be absent." She couldn't help complaining: "I just want to share the cup if I don't do anything. Geng, don't you have to be too good at business!"

In scientific research work, it is inevitable to encounter a partner who fishes in troubled waters. At least Zhang Chao is not a leader who enjoys the benefits.

Encountering? People who didn't do anything but took away the fruit and honor, that really makes people want to vomit blood.

Sheng Mingan: "At the beginning of the experiment, Zhang Chao volunteered to stare at the data all night. Now that the project is coming to an end, he has nothing to do. If there is something busy, it's okay to ask for leave."

He is not completely unreasonable, for people like Zhang Chao, the stage is in the social world, in the outside world, and the laboratory and scientific research projects are just decorations for rich resumes.

Moreover, Zhang Chao has a high emotional intelligence, knowing that the later experiments will not help him, so he took the initiative to take on the trivial, busy, and routine work of the fourth shift at the beginning.

Li Nan? Agreed, but didn't say much.

Sheng Mingan smiled, ready to finish the work.

Just at this moment, a voice came from behind: "Shen Sheng, Li Da? Beauty, I'm coming—" Zhang Chaoren heard his hearty laughter before he came in.

Li Nan was taken aback, and asked Zhang Chaolai how long it had been.

"Just here." Zhang Chao looked at Li Nan, grinning: "What? Li Da? Talking bad things about the beauty behind her back?"

Li Nan: "Who wants to speak ill of you." She was just stating the facts.

Zhang Chao: "I put a few cups of burnt fairy grass in the refrigerator in the tea room. You can eat them later. Oh, by the way, Shengshen, I see that you like to drink tea. How about drinking the tea in the tea room?" Out, so? I bought new tea cakes to put in."

Sheng Mingan was taken aback, and said, "How much is it? I'll send it to you."

Zhang Chao waved his hand: "No need, just a little thought, because I can't help you in the project, and I'm not too embarrassed..."

He scratched his head, his figure was a bit round, and his smiling face was a bit like Maitreya Buddha.

Is it still timid to fish in troubled waters? There is still a difference between knowing shame and introspecting as much as possible to make up for it. At least Li Nan's face is much calmer, and the resentment against Zhang Chao dissipates instantly.

Neither does Sheng Ming'an? Looking at Zhang Chao from Gao, his EQ is really high.

He met this kind of person in his previous life, and he also met someone who took other people's achievements as his own and was arrogant. There is no doubt that the former had a smooth life, while the latter lost his job and lost his job due to a report. reputation.

Having met many times, Sheng Ming'an knew that people like Zhang Chao's handling method is called high emotional intelligence, and they are most suitable for public relations or personnel departments.

Li Nan walked over to stare at the data, while Zhang Chao quietly walked to Sheng Mingan's side and whispered, "Thanks, Sheng Shen."

Sheng Mingan: "?"

Zhang Chao: "Speak for me just now."

He just overheard their conversation at the door.Sheng Ming'an thought so, and responded with 'hmm'.

Zhang Chao didn't care about his indifferent attitude. In fact, he was quite moved when he overheard Sheng Ming'an's speech at the door.

Knowing that he is not talented enough, isn't he the material for academics, so Zhang Chao started to manage contacts very early on, delved into the way of insurance research, and it was indeed as Sheng Ming'an guessed, he had a big heart Only when the thighs participate in various extra points competitions can they succeed in the postgraduate entrance examination.

Although opportunistic, he really put in the sweat of hard work, but this style has never been favored by serious academic scholars, so Zhang Chao tried his best to do errands.

In the past, he has been called around and ridiculed coldly. This is the first time he has been affirmed by an academic scholar. It is still a positive evaluation, and it is thicker and more awesome than any big leg he has ever hugged. the Great God.

Zhang Chao secretly observed Sheng Ming'an's side face, thinking that this is the real Great God, with extraordinary strength, tolerance and tolerance.

"I'm actually... busy starting a business recently."

Sheng Mingan turned around: "Ah, is that so?"

Zhang Chao nodded, gesturing excitedly: "It's just an app for campus job hunting, and a third-party headhunter."
