摘　　要：以某真空镀膜公司的产品为研究对象,运用排列图法找到造成产品不合格的主要原因。针对该主要原因,从工艺角度分析得到3个关键因子,运用假设检验,在显著性水平为0.05的情况下,得到这3个因子对产品不合格率均存在显著影响;并从这3个因子出发,运用方差和回归分析法对数据进行分析,寻找降低产品的不合格率的改进措施,对改进效果进行验证,降低了产品的不合格率。In this paper, the unqualified products of a vacuum coating company are taken as the research objects. Firstly, the main cause of the product disqualification is found by the Pareto diagram. Secondly, a hypothesis test is used to analyze the main cause and find that the three key factors from the view of technology have significant influence on the failure of products at the 0.05 level. Thirdly, based on the three factors, a variance analysis method and a regression analysis method are used to analyze the data in order to look for improvement measures to reduce the unqualified rate of the products. Finally, the improvement effect is verified, and the unqualified rate of the products is reduced.
