摘　　要：电镀零件的质量状况好坏会严重影响微波管的可靠性。本文运用多变量单值控制图法对微波管生产过程中零件镀层厚度进行统计控制,判断零件电镀是否处于统计受控状态,为进一步采取工程措施提供依据。The quality of electroplating parts affects the reliability of travelling wave tubes(TWTs)seriously.A statistical process control tool,multivariate individual observations chart is used to control the coating thickness of electroplating parts in TWT production,and judge whether the coating thickness is in statistical process control,which provides the basis for further engineering measures.

关 键 词：多变量单值控制图 电镀 镀层厚度
