摘　　要：家用冰箱结构设计要求越来越精细,统计公差技术在制造业中有着重要的应用,统计公差在制造过程统计质量控制及统计质量检验中发挥着重要作用,在产品开发阶段的尺寸设计中更是发挥着举足轻重的作用。本文将阐述统计公差分析在开发阶段的应用,如何利用过程能力(Cp)、过程能力指数(Cpk)、不合格率(Pd)等直观快捷的进行设计分析。The standard for household refrige-rator structure design gets more and more delicated. The statistical tolarance technolo-gy acts very important in the area of manufacturing, playing an important role in the manufacturing process of statistical quality control and inspection, it is a key element at the dimension design of product development as well. This paper will explain the application of statistical tolerance analysis in the development stage, and show how to use process capability （Cp）, process capability index （Cpk）, and percent defective （Pd）, etc., to conduct design analysis.
