1·Fluorescent lights use electricity to excite mercury vapor. This produces ultraviolet light that causes a phosphor coating inside the bulb to glow.
荧光灯用电激发水银蒸气。这会生成紫外线光而使得镀在灯管内壁上的磷涂层发光.
2·Air temperature and vapor pressure deficit were the key factors affecting transpiration.
气温和蒸气压不足是影响蒸腾作用的关键因素。
3·Another type of vapor separator is mounted on top of the tank.
另一种类型的蒸气分离器安装在燃油箱的顶部。
4·If oil vapor or other hydrocarbons to system cause problems, or processes can't deal with oil steam can be in the air, line installed oil steam filter.
如果油蒸气或其它烃类物质对系统造成问题，或工艺过程中无法处理油蒸气，则可在空气管线上安装油蒸气过滤器。
5·Although the glass shape did not affect the concentration of ethanol vapor, the temperature did, with chilled champagne releasing less ethanol, but the same amount of carbon dioxide.
虽然酒杯的形状并不影响乙醇蒸气的浓度，但对于释放少量乙醇的冰镇香槟而言，酒杯形状却能对相同数量的二氧化碳产生影响。
1·From what I remember, water changes back and forth from water in lakes and oceans to vapor, and then back to water again when it falls as rain or snow, as precipitation.
根据我的记忆，水往复地变化，从湖泊和海洋里的水变成水蒸气，然后当它以雨或雪——也就是降水的形式落下时又变成水。
2·Whether you're a river or invisible vapor, your inner nature never changes.
不管你是一条河流或是看不见的水蒸气，你内在的本质从来没有改变。
3·Besides the normal states of surface liquid, vapor, or ice, much water exists locked in rock hundreds of miles deep in Earth's mantle.
除了表面覆盖的江湖海水，水蒸气、冰，大部分水可能被锁在地球的地幔深处。
4·Clouds form when humid air cools enough for water vapor to condense into droplets or ice crystals.
当潮湿空气遇冷降至一定温度时，其中包含的水蒸气便聚集成小水滴或小冰晶，它们组成了云。
5·Only a small amount of water and detergent is needed to create the water vapor that allows the beads to work and loosen stains.
洗衣时，只需在洗衣机内加注少量水和洗涤剂，便足以产生洗衣所需的水蒸气，伴随塑料珠运转，衣物脱去污渍。 这种塑料珠能重复使用。
