润滑油产品在使用过程中蒸发,造成用油系统中油量的逐渐减少,润滑油粘度增大,影响供油。液压油在使用中蒸发,会产生气穴现象和效率下降,可能给液压泵造成损害。内燃机有的蒸发度过大,会使内燃机油在使用过程中消耗过快,导致油压不稳。因此必须对液压油等部分润滑油的蒸发度进行控制。

这就是一般所说的蒸发冷却过程,使AMO物理学家能够近似的靠近绝对零度和建立简单的宇宙热寂模型.
This so-called evaporative cooling process has allowed AMO physicists to reach the subnanokelvin domain and to achieve what are arguably the coldest objects in the Universe.
那些地区的降雨量没有太大变化,但是自1970年以来上升的气温已经超过了1摄氏度,由于蒸发这将会造成水分的更大流失。
There has not been much change in rainfall in those areas but the temperature has risen by over 1 degree Centigrade since 1970, which will have enhanced losses due to evaporation.
液态氮的沸点是零下320度,当它迅速蒸发时,会腾起一股《歌剧魅影》式(Phantom of the Opera)的白雾;同时,搅拌物的温度会骤然降低。
The blend rapidly chills as liquid nitrogen -- with a boiling point of -320 degrees -- instantly vaporizes in a billowing, Phantom of the Opera-esque fog.
