relative humidity
相对湿度───relative humidity
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。
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。
Relative humidity is expressed as percentage.───相对湿度采用百分数表示。
Test number effects roller ginned cotton breaking tenacity obviously, the next is regain, the last is relative humidity.───测试次数对皮辊棉断裂比强度的影响较为明显，回潮率次之，相对湿度的变化影响最小。
As you can see, the water content of a paper with the relative humidity of the air increased, with the loss of moisture.───可以看出，任何纸张的含水量都随空气相对湿度的提高而增加，随湿度的降低而减小。
The result shows that regain effects saw ginned cotton breaking obviously, the next is relative humidity, and the last is test number.───结果表明：回潮率对锯齿棉断裂比强度的影响较为明显，相对湿度次之，测试次数影响最小；
A relative humidity of 75% or more will increase the effectiveness of the procedure.
Autogenous deformations, internal relative humidity and compressive strength were recorded.
Space relative humidity will seldom exceed 40 %.
Average relative humidity is high throughout the year, ranging from 80 to 88% saturation, with an annual mean of 85%.
The relative humidity will be about 80% today.
