摘　　要：介绍了工序中同时控制多个相关质量特性均值向量的T2控制图方法。该方法用T2作为统计量，可简捷地画出控制图，监控工序有无失控现象。给出了计算公式及计算实例。In this paper the method on T2 control chart, by which the sample mean vectors of several related quality characteristics are controlled simultaneously in a process, is introduced. In this method the control chart can be simply and directly plotted using statistic T2. It can be applied for monitoring and controlling process. The compute formula and an example are given in this paper.

关 键 词：多变量工序控制 多元质量控制 质量管理
