What is the saying about the height of the door?

The high and low of the door is very particular, especially the older generation is more particular about this aspect, the door of the household is best flat and flat, must not be uneven, if it is low and there is a pit, there is a saying called going out into the pit, that is, falling into the ditch. If it is high and there is a mountain, there is a saying that you go out and hit the wall, and these statements are unlucky. In fact, it is really the case, the old man's saying is really not wrong, so when building a house, you must choose a good terrain, and you must not be so-so.

There is indeed a saying about the height of the door, because this is in Feng Shui, and this must be high and low at the door. The entrance to the back room should not be too high.

I don't think there's anything to say, and there's no taboo. Maybe the feudal ideas inherited from ancient times have that kind of saying. It's the age of technology, so you have to trust the science.

There are also a lot of boys at the door. Generally speaking, in addition to the threshold, the threshold and the threshold, it is best to be flat. Either it's okay to lower the threshold a little bit. This is good for Feng Shui.

It is the big gate that bullies the small gate, and the high gate (high door or high terrain) bullies the low gate. Therefore, it is better to have a door to door front that is a little higher and bigger than the door front of the door.

If the threshold is high, it means that the family conditions are better, and it is more difficult for others to enter his door. If the threshold is low, it only means that the family conditions are relatively average.

The height of the door is generally low, and it means that there is a life that cannot be lived.

Therefore, the general design should be flush with the door.

Some people deliberately cover the door higher than the opposite door, which is supposed to be superior. In fact, this is not good, if there are children in the family, it is easy to fall.

I don't think there's any explanation for this, generally speaking, it's about the same high, you can also make the same high.

There is not much to say in Feng Shui, and you don't have to worry too much about these, if you think about it more and more, the worse it will be.

Well, the saying of the mouth tour is to say that the size of the Egaoji at the door, the size of the high-looking, good-looking and the size mainly depends on a person's high-class.

There is nothing to say about the height of the door. Properly caused by the cause of injustice. Don't bother with that.

It's just a local custom, and he's also a kind of belief and a certain for an ordinary person. The perception of the problem.

There is a saying about the high and low steps at the door, but it is still necessary to place the position distance, and the height is not enough to see.

What is the saying about the height of the door? I think there must be a saying for the master, if you believe it, there is a saying, if you don't believe it, it's good.

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.

There is nothing to say about the height of the door, normal is fine.

The height of the gate is exquisite

1. The height of the office door is generally not less than 2m, and no matter how high it is, it should not be exceeded, otherwise there is a sense of hollowness, and the production of the door leaf needs to be particularly strengthened.

2. If modeling, ventilation and lighting are needed, waist windows can be added to the door, and their height should be from the beginning, but it should not be too high.

The width of the office door is exquisite

1. General office doors and sub-room doors, due to the consideration of the entry of modern office furniture, the upper limit size is now taken;

2. Office double doors, no matter how wide they are, they should consider the production of the door leaf, and the width of the door leaf of the double door or multiple doors is appropriate.

What are some feng shui tips for the office?

1. There is support behind the chair. Without the support of the back of the chair, there will be some invisible pressure on the back, which can make people feel nervous and irritable, and they will also be irritable when they are in a meeting or meeting with clients. A good backrest can prevent this from happening.

A comfortable office ensures success because people feel very relaxed, more confident, and ready to take on challenges in all directions.

3. Only one door is used in the office. If there are many doors in the office, close the rest except the one that comes in and out. This is also a principle of Feng Shui: let money only go in and out.

4. The office should not be brightly lit. Too much light can make people impatient and impulsive.

The door of the house should not be too high, otherwise it will be like a prison gate, which is very unlucky. The height of the outer gate is six and a half feet or seven feet and one inch (a little taller than a person). Doors should not be too narrow.

Traditional Feng Shui believes that the gate is an air port, and the air port should not be too narrow, if the gate is too narrow, it will make people feel oppressive and difficult to absorb vitality. The door of the residence should be coordinated with the pattern, and the gate of the mansion and the small door of the hut. Use the door to improve the feng shui of the home, and the aura enters from the door

The direction of the door, that is, these people are not good or all are good, isn't it a bit arbitrary.

1. Bedroom door to toilet door feng shui toilet door to bedroom door, one is to change the toilet door to the west position, that is, to open the door in the corridor position, so as to avoid the problem of the toilet door and the bedroom door You can hang a bamboo curtain or crystal curtain outside the toilet door, instead of hanging the whole curtain to the ground, you can hang half of the kind that you can, or you can hang a gourd at the bedroom door, change the direction of the bathroom door, or make a secret door. 2. The door of the bedroom is facing the door of the small bedroom, and next to the door of the small bedroom is the bed. It's bad feng shui.

Because the qi will rush to the small bedroom with people entering the house from the outside, the noisy people who rest in the small bedroom have poor sleep quality and do not gather wealth. A good solution is to install a screen at the door, on the one hand, it can be based on the wealth in the living room, and on the other hand, it can avoid the gas rushing to the small bedroom. But depending on the size of your room space, if it's too small to place a screen, try not to open the door of the small bedroom often, and move the bed in the small bedroom instead of going straight to the door.

Just close the door to the small bedroom as soon as you wake up early. 3. The bedroom door is the kitchen door Feng Shui The kitchen is fire from the five elements, and the bedroom door will make people more angry, anxious, and not good for health. The bedroom door flushes the kitchen and affects the heart, eyes, blood circulation, throat, lungs, bones, back, liver and gallbladder, hemorrhoids (hanging vine leaf plants in the left and right corners, or screen seals that are too high and wide over the door, and the door is often closed when entering and exiting), or after using the toilet or kitchen door, in the case of safely turning off any gas and electric switch, close the toilet door or kitchen door tightly, and try not to let the airflow of the anode cathode molecules outflow and affect health.

Door-to-door attention is "the two families cannot be opposite, and the main family must retreat; When you open the door, you must not rush to each other, and there will be a murderer."

Generally speaking, it is the party with a weak aura in the door who retreats, or the family with fewer people in the door retreats. As the saying goes, "one door is prosperous and one is declining", the two opposite each other will cause an imbalance in the aura, and the strong will suck away the aura of the opposite side, resulting in "the door eats the small door", which is also "the two doors are opposite, and one must retreat." When the two doors clash against each other, there will be a murderer.

Causes. The bedroom is a place to rest, and the door is the passage connecting the residence to the outside world, if the door is facing the bedroom door, this pattern will lead Sun Zhi to enter the door and see the bedroom directly. If the kitchen door is facing the bedroom door, the fire will rush straight to the bedroom, which will affect the daily rest of the residents.

Door-to-door solution:

1. Gate-to-door fiber.

If you are door-to-door with your neighbor's house, you can use screens, entrance partitions, or tall plants to block it, so as to solve the embarrassing situation of door-to-door.

2. Bedroom door to bedroom door.

Inside, the bedroom door is facing the bedroom door, and a round chandelier can be installed on the ceiling, or a potted plant with round leaves can be placed next to the door to avoid the door rushing. Another method is the simplest, and that is to close the door casually.

3. The entrance door is opposite the bedroom door.

In the face of this situation, you can design a screen at the entrance door, or a storage cabinet as a partition.

4. Kitchen door to bedroom door.

The kitchen is a place for cooking, and all kinds of oil smoke and fire will be heavier. If there is enough space, place a cabinet and screen between the two doors. If you don't have a lot of space, place greenery on both sides of the bedroom door. Another way is to close the door.

5. Bathroom door to bedroom door.

The bathroom is a place to take a bath and go to the toilet, which is heavy and prone to odor. You can hang a beaded curtain between the bathroom and the bedroom, or you can design a screen to block it. Alternatively, place greenery between two doors, preferably scented greenery that prefers shade and dampness.
