1·Then it snows because as the air rises, it cools off and loses its capacity to hold water vapor.

然后就会下雪，因为当空气上升时，它就会冷却并失去保持水蒸气的能力。

2·Such feedbacks might involve ice on land and sea, clouds, or water vapor, which also absorb radiant heat.

这种反馈可能涉及陆地和海洋上的冰、云或水蒸气，这些也会吸收辐射热。

3·Astronomers therefore prefer dry sites with little water vapor, which is generally found at higher altitudes.

因此，天文学家更喜欢水蒸气很少的干燥地点，而水蒸气通常出现在海拔较高处。

4·Efficient irrigation is often used to describe systems that result in 85% of the water disappearing in vapor.

“有效”灌溉通常指的都是一些让85%的水最终以水汽的形式逸散的作法。

5·One of these is the subtraction of water from the ocean by means of evaporation—conversion of liquid water to water vapor.

其中之一是通过蒸发的方式，把液态水转化为水蒸气——来减少海洋中的水分。

6·The same structure that permits the one gas to enter the leaf, however, permits another gas—water vapor—to be lost from it.

同样的结构允许一种气体进入叶子，然而，也使得另一种气体——水蒸气——从叶子中消失。

7·The same structure that permits the one gas to enter the leaf, however, permits another gas—water vapor—to be lost from it.

同样的结构允许一种气体进入叶子，然而，也使得另一种气体——水蒸气——从叶子中消失。

8·Within about a millimeter of the water, air temperature is close to that of the surface water, and the air is nearly saturated with water vapor.

在离水不到一毫米的地方，空气的温度接近于地表水的温度，空气中的水蒸气几乎饱和了。

9·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.

10·With temperatures rising and more water vapor in the air, such storms can pull in more moisture and thus rain or snow more heavily than storms of old.

随着气温升高，空气中的水蒸气增多，这样的风暴会吸收更多的湿气，因此雨雪会比以前的风暴来得更猛烈。

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。

水蒸气

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。
