摘　　要：本文通过对不可展曲面近似展开的整体及局部的误差分析，准确地掌握曲面近似展开的变形规律，为提高展开样板的精度提供了理论依据。本文提出的分析方法对一般规则曲面近似展开的精度分析也是适用的。In this papef, by analyzing the whole and part errors of approkimate development of undevelopable suthee of revolution, the deformed pattems can be grasped accurately.That will provide the theoretical basis for improving the precision of development model. The analytical method in this paper is also suitable for the approximate development of other surface of regulation.
