用方法精密度检验钛合金光谱分析标准物质的均匀性

Testing of Homogeneity of Titanium Alloy-ARM for Spectrometric Analysis by Precision of Analytical Methods

采用方差分析方案使用重复性(r)检验钛合金光谱分析标准物质均匀性的方法。结果表明:这种方法能较好地反映出受检样品的不均匀性,较之其他方法简单,方便,但要求比较严格。

In the testing of homogeneity of titanium alloy, candidate material for standard reference material （SRM） used in spectral analysis, critical values of repeatability limit （r） of the methods of analysis were used as criterions in judgement. As comparing with the method of variance analysis （F-testing）, the proposed method was proved to be a more strict and rigorous method, and also more simple and convenient in application. test
