摘　　要：根据干湿球方程和误差传递原理提出了干湿球法相对湿度测量精度的计算方法,能够利用干湿球温度及精度准确地计算出相对湿度的精度,并给出了计算实例。该方法还能够推广到其他相对湿度精度计算工作中。An algorithm of RH measurement precision with dry-and-wet bulb （DWB）was proposed according to DWB equation with error transfer theory. This algorithm can calculate the exact precision of RH according to the DWB temperatures and their precisions. The application of the algorithm was showed with example. The proposed method can also be extended to the precision calculation of RH measured by other approaches.
