Snow and rain, the air is the cooling water from the condensation, condensation is only when the degree of cold, and thus have rain, snow difference.
雪和雨一样，都是空气里的水汽冷却凝结而成的，只是凝结时天气冷的程度不同，因而有了雨、雪的区别。

Buffer extended the compressed air cooling and steam condensation of time, buffer automatic drainage function to avoid the liquid water in the bottom of the container sedimentary likely.
缓冲器延长了压缩空气冷却以及蒸气冷凝的时间，缓冲器的自动排水功能避免了液态水沉积在容器底部的可能。

The presence of clouds at night can also prevent fog formation of this type, because they trap the earth's heat, not allowing the cooling of the air for condensation.
