摘要
本文主要介绍一种在美国已被普遍采用的测量不确定度的计算方法。着重介绍这种方法的分析步骤、误差的分类、随机不确定度、系统误差限和总不确定度的计算方法,同时还探讨了这种方法尚待进一步研究的问题。最后,作为例子,给出了这种方法在风洞热流传感器校准试验中的应用。
A calculating method for measurement uncertainty exten-sively adopted in America is introduced.The analysis procedure,classifi-cation of measurement error,calculating of radom uncertainty,bias limitsof systematic error and total uncertainty for this method are emphasised.The problems of future research for this method are investigated.Finally,an applied example of this method in calibrations of the heat-flux gagesof the wind tunnel is presented.
