“仿射对应”用于画法几何的基本问题论述

Discussion on Some Basic Problems of the Application of "Affine Correspondence" to Descriptive Geometry

画法几何中，图示平面的正面和水平投影，构成一对仿射对应的特款—亲似对应的关系。应用这一对应的观点和方法，有助于画法几何解题。

In descriptive geometry,the frontal and horizantal projection of graphic expression can form a special related correspondence of affine correspondence.The application of this method is helpful to solving the problems in descriptive gepmetry.This paper aims at a more systemetic and deeper discussion on several basic problems of this corresponding relation in descriptive geometry.
