摘　　要：解平面尺寸链时,一般用投影法将其转化为直线尺寸链求解。对于不能简化为直线尺寸链的平面尺寸链,求解较为困难,不能运用简单的代数和求解。应用全微分概念,解平面尺寸链,概念清晰,计算简便。Flat dimensional chain is always changed into linear dimensional chain using projection method. It is very difficult to calculate when the flat dimensional chain can not be changed into the linear one, In this paper,differential is used to calculate flat dimensional chain, which not only makes the concept clearly, but also simplifies the process of analysis.

关 键 词：全微分 直线尺寸链 平面尺寸链
