摘要
本文介绍了圆锥曲线的一种新的定义方法—“配极象”法。同时证明了此定叉和传统定义的一致性及焦点准线性质。从而给出了以平面上任意点为焦点、任意直线为准线,任意正数为离心率的圆锥曲线的直接作图方法.
In this paper we give a new definition method of conic section-the polar recipro- cal image and we prove that this definition and traditional method are consistency.Thus,we give a make-graph method of conic section on plane with arbi- trary point as foci,arbitrary line as directrices and arbitrary positive number as eccentricity.
