尽管氧化钙有卓越的耐火特性，却很少使用到，因为和大气水蒸汽容易发生水合作用。
Calcium oxide although having excellent refractory properties is rarely used because of hydration by atmospheric water vapour.
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。
Water vapour in the atmosphere produces the strongest greenhouse effect, but it has been in balance for millions of years.
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。
This generated more water vapour in its atmosphere, further increasing the temperature in a runaway greenhouse effect.
寻找适合进行人工干预的气象条件，然后喷洒化学药品，大约需要出动8至10架飞机。 大气中并非所有的水蒸汽都能转化为降雨，至于降雪，水蒸汽首先应该形成冰晶。
Not all water vapour in the atmosphere turns to precipitation, and for the snow to fall, water vapour should concentrate on ice crystals first.
水蒸汽将充满大气层，所有的生命都将毁灭。
如果同易燃低温液体有关，在异常大气条件下，易燃混合物地带会延伸到空气中的水蒸汽的浓缩产生的正常雾云以外。
If a flammable cryogenic liquid is involved, the flammable mixture zone, under unusual atmospheric conditions, may extend beyond the normal fog cloud produced by condensing water vapor in the air.
这种强烈的紫外线辐射，将不可避免地通过分解大气中的水蒸汽和二氧化碳来释放出氧气。
This intense radiation would unavoidably have freed oxygen by decomposing the water vapour and carbon dioxide in the atmosphere.
掺杂锑的氧化锡厚膜，在氧化气氛中和含有一定水蒸汽的大气中，经常用于检测易燃气体。
The antimony-doped stannic oxide thick-film used to detect combustible gases in oxidizing and fixed water vapor-containing atmospheres.
