摘　　要：根据干湿球法测量相对湿度的原理,分析了干球温度、湿球温度、风速对相对湿度测量误差影响,对相对湿度测量合理选择测试仪表有一定的指导意义。Based on the dry and wet bulb method,the influence of dry bulb temperature,wet bulb temperature and wind velocity on measurement error of relative humidity were analyzed,the results have demonstrated that the measurement error is higher in low temperature and high humidity than that of in high temperature and low humidity.The studies are practicably instructive for selecting reasonable humidity measurement instruments.
