1·Water vapour condenses to form clouds.
水蒸汽冷凝形成云。
—— 《柯林斯英汉双解大词典》
2·The chemicals fired into the sky, usually dry ice or silver iodide, are supposed to provide a surface for water vapour to form liquid rain.
发射上天的化学物通常是干冰或碘化银，它们应该能为水蒸汽提供一个表面以凝结成雨滴。
3·Such a small change in stratospheric water vapour can have such a large effect precisely because the stratosphere is already dry.
平流层里水蒸汽含量如此微小的变动可以造成如此巨大的影响，正是因为平流层早己非常干燥。
4·Water vapour in the atmosphere produces the strongest greenhouse effect, but it has been in balance for millions of years.
大气层里水蒸汽产生的温室效应最强烈，但千百万年来一直保持着平衡。
5·This generated more water vapour in its atmosphere, further increasing the temperature in a runaway greenhouse effect.
这导致了其大气层里有更多的水蒸汽，进而，温度受失控的温室效应影响而更进一步的提高了。
1·Uncertainties in the future rate of (temperature) rise, stemming largely from the 'feedback' effects on water vapour and clouds, are topics of current research.
未来（温度）上升率的不确定性很大程度上由水汽和云层‘反馈’效果造成，这些是当前研究的课题。
2·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。
3·Water vapour accelerated the reaction distinctively.
水汽明显加快反应速率。
4·Water vapour in gas condensate reservoir has effect on the phase state of the gas condensate system.
凝析气藏中的水汽对凝析气体系相态变化有重大影响。
5·Water vapour in Gas condensate reservoir has an effect on the phase behavior of the Gas condensate system.
凝析气藏中的水汽对凝析气体系相态变化有影响。
