| 摘 要： | 对判断线性尺寸链增环、减环的环绕法进行了两种改进,环绕法对于尺寸线与基线交叉的不规则型线性尺寸链将无法直接使用,需要先将不规则型的尺寸链转化成规则型尺寸链后才能运用环绕法来进行判别.文中提出了利用等式判断不规则型线性尺寸链增环、减环的新方法.

| Abstract: | Two improvements were built for ring method which is used to determine increasing link and decreasing link of linear dimensional chain.As for irregular linear dimensional chain which dimension line intersects with base line,the ring method can not be used to determine increasing link and decreasing link.In general,the irregular dimensional chain should be transformed to regular one and then use ring method to determine increasing link and decreasing link.This thesis put forward a new method to determine increasing link and decreasing link by the equality relation. |
