人类的生存,动物的生长及工农业生产,都与周围环境的湿度有密切关系。为了创造一个舒适的生活环境,给动植物的生长提供一个合适的湿度条件,必须对周围的空气湿度进行检测控制。 大气中含水汽的多少用湿度来表示,大气湿度的表示方法有多种,经常用的是绝对湿度、相对湿度等。相对湿度为待测空气中的水汽分压与同温度下的水的饱和
Human survival, animal growth and industrial and agricultural production, are closely related with the humidity of the surrounding environment. In order to create a comfortable living environment, to provide a suitable humidity for the growth of plants and animals, the humidity of the surrounding air must be monitored and controlled. The amount of water vapor in the atmosphere is expressed in terms of humidity. There are several ways to represent atmospheric humidity, often with absolute humidity, relative humidity, and the like. The relative humidity is the water vapor partial pressure in the air under test and the water saturation at the same temperature
