“t”检验在新建分析方法评价中的应用

Application of"t"test in evaluation of new analytical methods

通过对化验室拟投用的CEAST 7027熔融指数仪对标准样品测试数据系统误差显著性的分析,评价该分析方法的适用性,从而介绍了“t”检验在新建分析方法评价中的具体应用。

Through the analysis of the significance of the systematic error[1]of the standard sample test data by ceast 7027 melt index instrument to be used in the laboratory,The applicability of this analytical method is evaluated,and the specific application of"t"test[2][3]in the evaluation of new analytical methods is introduced.
