Associations are more likely to occur when the partial pressure is high . 当水汽分压提高时，缔合更容易发生。
Air is the agent that transports water vapor from one region to another . 空气是把水汽从一地送到另一地的媒介。
Where one could look out through the wet window at the starry night . 从那里透过水汽蒙蒙的玻璃可以望到外面的星夜。
However, it does not require an absorbed vapour layer to become effective . 然而，它不需要被吸收的水汽层来发挥效能。
As the optical mass of water vapour increases, so does the solar absorption . 随着水汽光学质量的增加，太阳吸收也增加。
Water vapour and clouds are the primary variables modulating direct solar absorption . 水汽和云是调节直接太阳吸收的主要要素。
This, in turn, reduced the transport of heat and water vapor to and from the plant . 这样反过来又减低了热和水汽从植物中的进出量。
In effect, air may be regarded as a sort of sponge, filled more or less completely with water vapor . 事实上，空气可被看作是一块海绵，或多或少地含有水汽。
She leaned forward, looking through the car's steamy windows at the snow outside, now falling heavily . 她俯身向前，透过布满水汽的车窗望着外面已经漫天飞舞的大雪。
No other gases would be present to prevent ultraviolet solar radiation dissociating water vapour at the top of the atmosphere . 没有其他的气体去阻止紫外太阳辐射离解大气层顶的水汽。
