1·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。
2·Because warm air can hold more moisture than cool air, the relative humidity will be constant only if the amount of water vapor in the atmosphere increases as the temperature rises.
因为温暖的空气比冷空气能容纳更多的湿气，所以只有当大气中的水蒸气量随着温度的升高而增加时，相对湿度才会保持不变。
3·High variation in relative humidity.
相对湿度差异大。
4·Relative humidity is expressed as percentage.
相对湿度采用百分数表示。
5·Presents the control method of relative humidity.
介绍了系统相对湿度的控制方法。
6·The relative humidity is the main affecting factor.
相对湿度是影响光合的主要因子。
7·The relative humidity is expressed as a decimal or a percentage.
相对湿度以小数或百分数表示。
8·In summer people feel sticky in that relative humidity is quite high.
夏季人们感到皮肤粘乎乎的是因为相对湿度很高。
9·Decreased relative humidity induces decreased net photosynthetic rate.
相对湿度降低，净光合速率也降低。
10·Temperature and relative humidity can also affect the surface resistance.
温度和相对湿度也会影响表面电阻。
