| 摘 要： | 本文介绍了圆锥曲线的一种新的定义方法－“配极象”法，同时证明了此定义和传统定义的一到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。

| Abstract: | 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. |
