Autumn twilight in the mountain dwelling. It is a five-character poem. According to the rhythm, the middle of the five laws is a two-fold battle.
That is: the bright moon shines among the pines, and the clear spring stone is upstream. (Battle).
The bamboo noise returns to the Huannu, and the lotus moves the fishing boat. (Battle).
The battle must be fought not only in words and words, but also in the structure of sentences. The detailed analysis for you is as follows:
The bright moon on the clear spring. They are both more formal compound nouns, bright moon, clear spring water.
Matsuma Teru is upstream. Pine, pine forest, means place, is an adverbial of the verb "shine"; Shishang, above the stone, also means place, is an adverbial of the verb "flow".
They are all subject-predicates, with a clear moon shining among the pine forests and clear spring water flowing on the stones.
Pronunciation: 仄 (可平) 仄平平仄, 平平仄 ("stone" is a phonetic word in ancient times.
Voice) Ping.
Bamboo noise to lotus. They are both subject-predicate phrases, bamboo.
There was a loud noise, and the lotus leaves swayed.
Align below. return, return; Down, back upstream.
Raccoon girl to fishing boat. are all more formal compound nouns, girls washing clothes, fishing boats.
They are all inverted sentences.
Cause and effect are reversed), because the washerwoman comes home and touches the bamboo and makes a noise, because the fishing boat comes home and touches the lotus leaf and shakes.
Pronunciation: 平 (可仄) 平平仄仄, 仄 (可平) 仄仄平平.

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.

From the perspective of rhythm, this is a landscape poem, "Mountain House Autumn Twilight".
It was the Tang Dynasty poet Wang Wei.
of poems. It is like a fresh and beautiful landscape painting, and like a quiet and beautiful lyrical music, which embodies the creative characteristics of Wang Wei's poems.
This poem depicts the beautiful scenery of the mountain village and the simple fashion of the mountain villagers in the evening after the early autumn rain, and expresses the poet's affection for the landscape and pastoral and the satisfaction of the secluded life, and expresses the beauty of personality and society with natural beauty. The whole poem harmoniously blends the coolness of autumn after the rain in the empty mountains, the light of the bright moon among the pines, the sound of the clear spring on the stone, the laughter in the bamboo forest when the raccoon girl returns, and the dynamics of the fishing boat passing through the lotus flowers, giving people a rich and fresh feeling.

1. Autumn twilight in the mountain dwelling.
Author] Wang Wei [Dynasty] Tang.
After the new rain in the empty mountains, the weather is late in autumn. The bright moon shines among the pines, and the clear spring stone is upstream.
The bamboo noise returns to the Huannu, and the lotus moves the fishing boat. Feel free to rest in spring, and the kings and grandchildren can stay.
Translations. The empty mountains are bathed in a fresh rain, and the night falls to make people feel that it is early autumn. The bright moon sprinkled clear light from the pine gaps, and the clear spring water flowed on the rocks.
The noise of the bamboo forest knew that it was the return of the laundry girl, and the lotus leaf shook gently to think that it was a light boat wandering. The fragrance of spring may as well be let to rest with it, and the kings and grandchildren of the mountains in autumn can stay for a long time.
2. Drinking alcohol (fifth).
Author] Tao Yuanming [Dynasty] Wei and Jin.
The knot is in the human realm, and there is no noise of cars and horses. How can you ask you? The heart is far away from itself.
Picking chrysanthemums in the east fence ridge is pure, leisurely see the South Mountain. The mountain weather is good, and the birds are returning.
There is a true meaning in this, and I have forgotten to distinguish it.
Translation: He lives in the world, but there is no noise of chariots and horses. Ask me why I can? As long as you have high aspirations, you will naturally feel that the place you are in is secluded.
Picking chrysanthemums under the east fence, leisurely, the distant Nanshan Mountain comes into view. The smell of the mountains and the evening scenery are very good, and there are birds flying and returning with children. This contains the true meaning of life, and I want to recognize it, but I don't know how to express it.
3. Ask Liu 19.
Author] Bai Juyi [Dynasty] Tang.
Green ant new brew wine, red clay small stove.
If you want snow in the evening, can you drink a glass of nothing?
Translation: I brewed the pale green rice wine and burned the small stove. The sky will be getting thicker and thicker, can you take a look at the cold house and drink a glass of warm wine.
Fourth, return to the garden and live in the countryside.
Author] Tao Yuanming [Dynasty] Wei and Jin.
Planting beans in the south of the mountain, the grass is full of bean seedlings. Morningside is desolate, and returns with the moon and lotus.
The road is narrow and the grass and trees are long, and the evening dew stains my clothes. It is not a pity to stain the clothes, but the wish is not violated.
I planted beans at the foot of the South Mountain, and the fields were full of weeds and sparse bean seedlings. Get up early in the morning to eradicate weeds, and return with a hoe in the moonlight at night. The narrow mountain path was overgrown with vegetation, and the night dew soaked my clothes.
It's a pity that my clothes are wet and I want to travel, I just hope that it will not go against my will to return to the farm.
5. Drinking, fourth.
Author] Tao Yuanming [Dynasty] Wei and Jin.
Qiu Ju has a good color, and she is dewed and beautiful. Forget this worry, far away from my world.
Although it is alone, the cup is self-pouring. The day into the flock, the birds tend to the forest.
Xiao Ao Dongxuan ordered the cherry blossoms to talk about recovering this life.
Translations. Autumn chrysanthemums are in full bloom and bright, with dew and moist flowers. The taste of chrysanthemum wine is more beautiful, and the feeling of avoiding vulgarity is deeper.
Drain the wine in the glass with a wave, and then hold the wine jug and pour it into the glass. At sunset, all living beings stopped, and the birds sang happily to the forest. Indulge in singing under the east window, let's spend this life freely.

1. "Mountain House Autumn Twilight", "Fengqiao Night Park" and "Sauvignon Blanc" have in common:
It's all lyrical through scenes2. The differences between "Autumn Evening in the Mountain House", "Fengqiao Night Park" and "Sauvignon Blanc":
1. "Autumn Evening in the Mountain House" expresses the poet's satisfaction with knowing this landscape and pastoral and being content with his secluded life
2. "Fengqiao Night Park" fully expresses the author's thoughts about travel, the worries of his family and country, and the worries of being in a troubled world and not having a home
3, "Sauvignon Blanc" expresses the long state of mind of deep feelings

The first couplet is to write about the autumn scenery in the mountains after the rain, because there are few people here, naturally I don't know that someone in the mountain is coming. The word "empty mountain" knows that this place is like a paradise, the mountain rain is at the beginning of the day, everything is new, and it is the evening of early autumn, the air is fresh, and the scenery is beautiful and rotten, which can be imagined.
