摘　　要：针对采用干湿球法对未饱和高压蒸汽恒定湿热试验设备的湿度参数进行测量时得到的干球温度和湿球温度,利用经验公式计算代替查蒸汽表法得到相对湿度可以显著提高数据处理的效率。在相同的干球温度和湿球温度条件下,通过采用经验公式计算得到相对湿度值和查蒸汽表得到的相对湿度值进行比较,可以确认由于方法误差带来的影响可以忽略不计时,对于采用经验公式代替查蒸汽表得到相对湿度提供依据。In view of the dry bulb temperature and wet bulb temperature obtained when the humidity parameters of the Unsaturated Pressurized Vapour Damp Heat/Steady State Testing Equipments are measured by the dry and wet bulb method,the relative humidity calculated by the empirical formula instead of the steam table method can significantly improve the efficiency of data processing.Under the same dry bulb temperature and wet bulb temperature,the relative humidity calculated by using the empirical formula is compared with the relative humidity obtained by checking the steam table.It can be confirmed that the influence caused by the error of the method can be ignored,and it provides a basis for using the empirical formula instead of checking the steam table to obtain the relative humidity.
