What does it mean to see a chicken laying eggs in front of the house on the first day of the new yea

On the first day of the new year, the chicken lays eggs, indicating that the chicken wings are very diligent in the year, and may lay a lot of eggs, which also means that the owner of the chicken will be very rich.

It means a year of good luck, prosperous business and financial resources!

It represents that the ecological environment around the door of the house is more curious, and the door of the house likes to lay eggs in the environment, which is a good sign.

The new year has seen a new life, which is a very good sign.

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.

This year, there will be a new addition to the family.

Of course it's a good thing! Think about it, every time you celebrate your birthday or go out, your family will boil a few eggs, "chicken" through "auspicious", your family will have "auspicious" at the beginning of the year, and it is too late for others to envy it.

There is no sign that the hen enters the house to lay eggs, that is, the hen's normal behavior is light, if it is a dream, it is estimated that there have been good things and happy events recently.

What is the sign of a hen coming into the house, this is normal, because it is time for him to lay eggs, treat her well, let him lay more eggs for you, nothing normal.

Well, the eggs are bright, the egg white flowers, like gold and silver, the eggs are round and can roll, the chickens lay eggs, and the eggs and chickens stretch endlessly. The whole metaphor is that the wealth is rolling in. You're going to get rich!

Is this a problem? It's normal.

There is nothing good or bad, just happy yourself.

I think it's just a coincidence, hens laying eggs are the most ordinary things, and they don't indicate any good or bad signs, so just treat them with a normal heart.

Zhixing hen laying eggs is a good sign, housewarming is already very happy, hens are still laying eggs, can it be bad?

The joy of housewarming hen lays eggs, according to folklore, this is a good sign, housewarming of the joy of hen laying eggs, not only you bring wealth, but also the prosperity of future generations, at the same time there is a saying of escape, may have good fortune in life, and everything will be smooth sailing.

That's a good sign, a great joy, the hen will increase your wealth, but don't overjoy, and keep a low profile, and be steady

Of course, it is a good sign, housewarming is a good thing, and the hen lays eggs and has wealth, which is a good thing to be happy and happy.

Generally, the rural saying is that happy events meet such things as giving birth to babies and laying eggs, which is joy and joy.

It's all good things, and it's good to feel good when you encounter it.

The whole single broken eggs are good news for the year and the year is prosperous, don't beat the chickens and eggs.

If there is nothing to do, how can there be anything.

It's normal to see eggs, what's the use of selling eggs outside? You feel that something is going on, it's your own psychological effect.

I feel like it's good to go out and see eggs.

What you think is good or bad is your personal opinion, and you can think of him as good.

It should be fine, why don't you care about it when you eat.

All is well, and it will be all right.

This has no special meaning, it is just a local custom, which is generally to seek advantages and avoid disadvantages.
