例句
-
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·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。
-
5·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。
-
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·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。
-
8·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。
-
9·The assumption of constant relative humidity is important, because water vapor in the atmosphere is another efficient absorber of radiation at infrared wavelength.相对湿度恒定的假设是重要的，因为大气中的水蒸气是红外波长辐射的另一种有效吸收剂。
-
10·An increase in temperature, for example, can boost the moisture content of the atmosphere, which then causes further warming because water vapor is a greenhouse gas.例如，温度的升高会增加大气中的水分含量，这又会导致进一步的变暖，因为水蒸气是一种温室气体。
