摘　　要：对能力验证样品均匀性评价的单因子方差分析法和SS≤0.3σ准则进行了阐释,并结合振动试验能力验证样品的均匀性计算案例,验证了以单因子方差分析法作为样品均匀性评价的初步方法,以SS≤0.3σ准则作为试验结果返回后样品的均匀性评价方法,可有效提高样品均匀性评价结果的可靠性。The single factor analysis of variance and SS≤0.3σare two statistical methods.With the vibration test ability to verify the homogeneity evaluation case,it is verified that the single factor analysis of variance is the primary method to evaluate the homogeneity,and the method of SS≤0.3σevaluation is applied after the test results returned,can effectively improve the reliability of homogeneity evaluation results.
