摘要
本文根据正亲似对应的特性．首行推导出建立两个椭圆正亲似对应的普适数学公式．并以此为基础．进一步研究了用计算法在给定的椭圆柱上激出与预定的椭圆形状和大小完全相同的椭圆时，截平面及截交线椭圆的长短轴的空间位置。
In this poper, according to special charaCteristic of straight relative similarly correspondence, first, general applicable mathematical formula of setting up two ellipses into straight relative similarty corresPOndence is deduced, and based on the above formula when ellipse hat is the same as predetermine ellipse is cut off on the given ovalshaped pillar, the space position of cross-section and long or short axis of the ellipse that is produced from the plane and the ovalshaped pillar intersecting are studied with calculating method.
