摘　　要：动态测量中的温度变化会使测量结果产生温度误差。采用插入高精度标准信号的误差实时分离方法无法将温度误差从测量信号中分离出来 ,因此必须在动态测量误差修正灰色模型中加入测量仪器的温度误差项 。The temperature variation in dynamic measurement will cause temperature errors in the measuring results. The temperature errors can't be separated from the measuring signals by using a real time error separating method to interpolate high precision standard signals. So the temperature errors of measuring instrument have to be added to the gray model of error correction in dynamic measurement to improve the error correction accuracy of the model.
