"Dewdrops wet the sand wall, and dusk is silent" comes from that poem?
Translation:
Dew wet the desolate desert, revealing a little loneliness in the boundless; Drinking alone in the country pub late at night, missing the beautiful women taken away by Xiongnu in the distance; Tears wet the Jin Ge armor at hand, and the Iraqi figure gradually dances away; Make an oath in your heart: If you can't bring your fragrant body back to this homeland, let your body be buried in the boundless grassland and accompany you forever.
Extended data:
Scientific basis:
Dew is found in all seasons, especially in autumn. On a clear and cloudless night, the ground heat dissipates quickly and the ground temperature drops quickly. When the temperature drops, the ability of air to contain water vapor decreases, and the water vapor in the lower atmosphere adheres to grass, leaves, etc. and condenses into tiny water droplets, that is, dew.
Dew can only be formed under the weather conditions of stable atmosphere, small wind, clear sky and local cloudy ground heat loss. If there are clouds in the sky at night, the ground is like a quilt. After the heat reaches the clouds, part of it returns to the ground.
The other part is absorbed by the clouds, and the heat absorbed by the clouds will slowly radiate to the ground in the future, so that the temperature of the ground is not easy to drop and dew is not easy to appear; If the wind is strong at night, the wind makes the upper and lower air communicate, which increases the temperature of the air near the ground and makes the water vapor diffuse, so it is difficult to form dew.
