Unexpected. Most of the stories are made up and regular, but accidents can happen anytime and anywhere in real life.
Logic is not a matter of language, but of thinking. In other words, the essence of language is the way we think.
How you explain something, how you think about a problem, often reflects your cognition. Your understanding of the outside world, taken together, constitutes your cognitive world.
Your perception of the world is more important than what the outside world is like. Because you need to go through this cognitive world to receive information, understand information, and output information. It's your mind that's in charge.
This is what logic is all about: it's not just a tool for communication, it's a way for our brains to work.
So, what exactly is logic? What does logic consist of? What are some ways to help us improve our logical thinking skills?
This is a huge problem. To explain logical thinking clearly, it is necessary to take a whole course.

There will be logic in the story, but not in life. It means that most of the stories are made up and regular, but accidents can happen anytime and anywhere in real life.

That is to say, stories have an outline and logic, and there are contradictions and conflicts to become a story; And life is a day by day, no matter what life you live is your choice, she has no inevitable logic.

Discharge cooling is another type of convection cooling. Unlike regenerative cooling, the coolant used for exhaust cooling absorbs heat to the thrust chamber and is discharged out of the combustion chamber instead of entering the combustion chamber to participate in combustion. Direct drain coolant reduces the thrust chamber specific impulse, so the coolant flow for drain cooling needs to be minimized while only using drain cooling at the outlet section of the nozzle that is relatively less heated.
There is also radiative cooling, in which the heat flow is transferred from the combustion products to the thrust chamber, and then the heat is radiated by the thrust chamber wall to the surrounding space. Radiative cooling is characterized by simplicity and small structural mass. It is mainly used in the extension section of large nozzles and the thrust chamber of small thrust engines using high-temperature resistant materials.
When cooling in the thrust chamber of the tissue, a relatively low temperature liquid or gas protective layer is established on the surface of the thrust chamber wall to reduce the heat flow to the thrust chamber wall, reduce the wall temperature, and achieve cooling. Internal cooling is mainly divided into three methods: internal cooling (shield cooling), membrane cooling and diaphoretic cooling of head tissues. After the internal cooling measures are adopted in the thrust chamber, the mixing ratio near the wall of the combustion chamber is different from the optimal mixing ratio in the central area (in most cases, the near-wall layer rich in fuel is used) due to the need to reduce the temperature of the protective layer, resulting in the uneven distribution of the mixing ratio along the cross-section of the combustion chamber, so that the combustion efficiency is reduced to a certain extent.
Membrane cooling is similar to shield cooling in that it cools the thrust chamber wall by establishing a uniform and stable coolant film or air film protective layer near the inner wall surface, except that the coolant used to establish the protective layer is not injected by the injector, but is supplied through a special cooling belt. The cooling band is generally arranged in a cross-section of the combustion chamber or the convergence section of the nozzle. There can be several cooling bands along the length of the combustion chamber.
In order to improve the stability of the membrane, the coolant often flows through the gaps or small holes in the cooling belts, and when sweating is used, the thrust chamber wall or part of the inner wall is made of porous material with a pore diameter of tens of microns. Porous materials are usually sintered with metal powders or pressed with metal mesh. In this case, the number of pores per unit area is increased by making the micropores in the material as evenly distributed as possible.
The liquid coolant penetrates into the inner wall, creating a protective film that reduces the density of the heat transferred to the wall. When the flow rate of liquid coolant used for sweat cooling is above a certain threshold, a liquid film is formed near the wall of the thrust chamber. When the coolant flow rate is below the critical flow, the inner wall temperature will be higher than the coolant boiling point at the current pressure, and some or all of the coolant will evaporate, forming an air film.
In addition to the above thermal protection, there are other thermal protection methods such as: ablation cooling, thermal insulation cooling, hot melt cooling and composite protection of chamber walls. 3. Thermal protection scheme of high enthalpy gas generator Based on the above methods and the actual situation, the thermal protection method of high enthalpy gas generator is obtained.
The combustion chamber of a high-enthalpy gas generator differs from that of a liquid rocket engine, eliminating the front thrust chamber part, making its structure simpler and more effective. Then, the thermal protection involved is the thermal protection part of the combustion chamber wall. As the fuel enters the combustion chamber, it quickly decomposes and releases large quantities.

1.The story is mostly fictional, or adapted from reality, it has a main line, cause and effect, or it happens around a topic. But this is not the case in reality, people in reality are exposed to different industries and things every day, people and people, people and things have all kinds of intersections and empty sets, it is likely that what he does today has nothing to do with what he will do tomorrow, or it may be that nine of the ten things he does have no clear result at all, and the development of things will not be like in the movie, there is a beginning and an end.
A story can be understood as a microcosm of reality or a modified mapping, so a story is more logical than a display.
2.People don't want to see something bad happen, so stories are often based on human will, and naturally most of them will have a good ending. The story presents the beautiful things that people are pursuing, and adds some emotional human factors or wishes.
But the reality is that there is no plot to speak of, no embellishments or changes have been added, and most real things do not have a happy ending like the story. There will be a clear direction of story development when making up a story, how the story plot develops, how to set off, how the characters are prominent, etc., which are embellished, but the reality does not have a clear development direction, and no embellishment is added.
3.In the story, there will be people who will always take the bridge to swim the protagonist's halo, and all the people and things revolve around him, but in reality, everyone is their own hero, and everyone is self-centered, so when everyone becomes their own hero, things are not like that. Not everyone's expectations will be fulfilled, and not everyone can have all kinds of wonderful experiences.
In reality, if an ordinary person can do ordinary things well, he is already very successful, and most people are mediocre but can feel happy. Therefore, don't do extreme things easily, don't take risks like the people in the movie, anyone can be successful, but the ratio of success and failure is very different.

Reality is much more exciting than TV series, this liquid is recognized, and the imagination of the story is really not very rich, because many normal people can't imagine the evil of people. There are some bloody plots outside the other base, which are more cowhide than in the story.

1. At the dinner table just now, the eldest aunt, who has worked in the hospital for many years, said very seriously: "...In the orange juice drink, a lot of coloring and flavor are added; The boiled beef, sauerkraut fish, durian crisp and so on that are often ordered in restaurants are all kinds of additives, including this plate of braised pig's trotters on our table-" As she was talking, she suddenly sandwiched a large piece of pig's trotters into her bowl, "But I still like to eat it very much!" ”

There is a phenomenon called "broken window effect" in the psychology of the broken window effect, that is, if the windows of a house are broken and no one repairs them, other windows will be broken inexplicably after a while; On a wall, if some graffiti is not cleaned off, soon, the wall will be covered with messy and unsightly things. In a very dry and clean place, people will be embarrassed to throw garbage, but once there is garbage on the ground, people will throw it without hesitation, without any shame. This is a very strange phenomenon.
It is this "tipping point" that psychologists study how dirty the ground must be, so that people will feel that it is so dirty anyway, and it doesn't matter how dirty it is, and how bad the situation is, people will give up on themselves and let it rot to the end. If any bad thing is not stopped at the beginning, it will form an atmosphere and cannot be changed, just like a river embankment, if a small gap is not repaired in time, the dam can collapse, causing millions of times the loss. Crime is actually the result of disorder, and in the 80s, New York City was really robbing everywhere, killing every day, and walking on the road in broad daylight would be afraid.
Not to mention the subway, the carriages are dirty and messy, scribbled everywhere, and everyone is in danger when they sit in the subway. Although I was not robbed, one professor was beaten on a dull stick in broad daylight and lost his eyesight, which ended his research career, and I did not dare to go to New York for many years. Recently, New York's appearance and reputation have improved considerably, and I am quite surprised that a city that has sunk down can come back from the dead and rise upward.
Therefore, when I went out to a meeting and met a criminologist, I immediately asked him for advice, and it turned out that New York City used the theory of the broken window effect mentioned in the books, first improving the criminal environment so that people would not be able to commit crimes, and then slowly arresting the murderers and thieves, and then returning to order with the knowledge of Zhengying. At that time, although this practice was scolded as not urgent, "the ship is sinking and the deck is still washing", but New York City still started by maintaining the cleanliness of the subway cars, and handcuffed the people who did not buy tickets and took the train in vain to stand in a line on the platform, and publicly declared to the people the determination to rectify, which turned out to be very effective. The police found that people really did not commit crimes in clean places, and found that it was very difficult to catch fare evasion, because one out of every seven fare evaders was a wanted criminal, and one out of twenty people carried **, so the police were willing to catch fare evasion very seriously, which made the gangsters dare not evade the fare and dare not bring ** when they went out, so as not to lose more than they gained, and they lost a lot because of a small loss.
In this way, New York City starts with the smallest, easiest place, breaking the criminal chain and preventing the vicious cycle from continuing.

Birdcage logic hangs a beautiful birdcage in the most conspicuous place in the room, and after a few days, the owner will definitely make one of the following two choices: throw the birdcage away, or buy a bird and come back and put it in the birdcage. This is the birdcage logic.
The process is simple, imagine that you are the owner of this room, and as soon as someone walks into the room and sees the birdcage, they can't help but ask, "What about the birds?" Is it dead?
When you: "I've never had a bird in the forest. "People will ask
So, what do you want a birdcage for? "In the end you have to choose between two options, because it's much easier than endless explanations. The reason for birdcage logic is simple:
Most of the time, people adopt inertial thinking. Therefore, it can be seen how important it is to cultivate logical thinking in the life and work of Jinchun socks.

Learned helplessness experimentsThe learned helplessness effect was first discovered by Overmere and Celegman, and has since been widely studied in animals and humans**. To put it simply, many experimental manuscripts show that dogs can be trained to roll over barriers or engage in other behaviors to escape the shocks imposed on them by the experimenter. However, if the dog has previously received an unanticipated (not knowing when it will come) and uncontrollable electric shock (e.g., the interruption of the shock does not depend on the dog's behavior), when the dog later has the opportunity to escape the shock, they also become powerless to escape.
Moreover, dogs also show other deficiencies, such as feeling frustrated and depressed, reduced initiative, and so on. The reason why the dogs exhibited this condition was due to a sense of helplessness learned early in the experiment. That is, they recognize that they cannot control the termination of the shock no matter what they do.
In each experiment, the termination of the shock was under the control of the experimenter, and the dog learned a sense of helplessness by recognizing that he was incapable of altering this outside control. When a person develops learned helplessness, it becomes a deep despair and sorrow. Therefore, we should broaden our horizons in study and life, see the real determinants behind events, and not let ourselves fall into despair.
