示值相对误差测得值的不确定度评定方法的探讨

Discussion on the Evaluation Method of Uncertainty of Measurement Results of Relative Error of Indication

本文针对示值相对误差的计算方法,采用理论和公式推导的方式,从原理上和不确定度评定过程中对示值相对误差测得值不确定度的两种评定方法进行了探讨,以便正确理解、区分、应用示值误差与示值相对误差的不确定度和相对不确定度。

In this paper,according to the calculation method of relative error of indication,two evaluation methods of uncertainty of measurement result of relative error of indication are discussed in principle and in the evaluation process of uncertainty by using the method of theory and formula derivation,so as to correctly understand,distinguish and apply the uncertainty and relative uncertainty of indication error and relative error of indication.
