数理统计在防锈油防锈性试验方法标准制定中的应用

APPLICATION OF MATHEMATICAL STATISTICS TO STANDARD FORMULATION FOR ANTIRUST TEST OF ANTIRUST OIL

在防锈油防锈性试验方法中，用t检验方法验证和评价改变试验材料的可行性。通过标准偏差计算反映该试验方法的精密度，确定允许差。

To verify and evaluate the feasibility of the change of testing material, t-test was used in examination of the power of antirust oil. The precision of t-test was manifested through standard deviation calculation and the allowable deviation was determined.
