摘　　要：本文根据空间场的透视仿射对应原理，利用拉伸（压缩）对应变换，解决了一般平面与非回转面截交线投影的一种简单作图方法．On the basis of the theory of the correspondence of perspective affinity in the spacing field, this paper gives a kind of simple construction procedure to solve the cross -section curve of a general plane and a non-revolution surface, by using ocrres ponding transformation tension (or contraction).
