摘　　要：将复杂二维尺寸链问题分解为单个组成环问题进行处理,对单个组成环的传递累积过程进行分析。按约束方式与测量方式的组合进行分类,分析了组成环对封闭环的贡献度,得到了公差传递系数。In this paper, the complex problem of two-dimensional chain is decomposed into individual components,the individual composition ring cumulative process were analyzed. Restraint and their measurement methods are used to classify and analyze the contribution of the composition ring,and get the tolerance transfer coefficient.
