摘　　要：通过分析现有标准方法中因忽略温度传感器的动态特性所引入的误差,提出了一种动态温场的校准方法。该方法考虑了温度传感器的动态特性对动态温场校准结果的影响,使用连续记录温度曲线的方式代替现有较长记录间隔的数据记录方式对温场的动态性能进行测试,并结合不确定度分析的手段,给出被测动态温场校准结果。In this paper,a calibration method for dynamic temperature field is proposed by analyzing the error introduced by ignoring the dynamic characteristics of temperature sensors in existing standard methods.This method considers the influence of the dynamic characteristics of the temperature sensor on the dynamic temperature field calibration results,uses the continuous recording of the temperature curve instead of the existing data recording method with a long recording interval to test the dynamic performance of the temperature field,and combines the uncertainty analysis to give the confidence interval of the measured dynamic temperature field calibration results.
