浅谈测量不确定度在化学分析中的应用

On Application of Measurement Uncertainty in Chemical Analysis

在化学分析中,需要通过度量与结果的可信度来证明结果的适宜性,这一般包括期望某个结果与其他结果相吻合的程度,通常与所使用的分析方法无关,度量该项内容的一个有用的方法就是测量不确定度。通过对空气中氨浓度测定不确定度的实例分析来掌握不确定度的含义及其在化学分析中的应用。

In chemical analysis,the suitability of analysis results has to be proved by the credibility of measurement andresults. This generally includes the matching degree of an expected result with other results,which has nothing to do withanalysis methods. One useful method is the uncertainty measurement. This paper,through a real case of uncertainty measurementof ammonia concentration in air,introduces the definition of the method and explores its application in chemicalanalysis.
