摘要
通过对相对湿度与干湿球温度间数据的分析，推导出了由干湿球温度计算相对湿度的两个数学公式，计算中不需查阅水蒸气数据表和试差，准确度较高，适于工程计算。在相对湿度≥４０％，湿球温度０～８０℃，风速＞５ｍ／ｓ的空气—水蒸气系统，平均相对误差为１．７％和１．１％。
Through analysis of data between relative humidity and dry-bulb and wet-bulb temperature,two methematical formula are deduced for the calculation of relative humidity from dry-bulb and wet-bulb temperature.It is suitable for engineering calculation with high accuracy and it needn't look up vapor data and calculate by trial and error in the calculation.The average relative error of relative humidity value calculated from two formula is 1.7% and 1.1% respectively for the system of air-vapor with relative humidity≥40%,wet-bulb temperature 0～80 ℃ and wind speed>5 m/s.
