摘要
本文介绍透视仿射交换在轴测椭圆中的应用和作图分析。通过求出对应椭圆的长短轴，可作出实形轴测椭圆。透视仿射交换可用于求两个几何体任意截交线。
This paper introduces the application and graphic analysis of perspective affine transformations in axonometric ellipse.Because the major and minor axes of the ellipse can be found, we can make the actual axonometric ellipse. This method can also be employed in making any kind of actual cutting curve between two seometric solids.
