| 摘 要： | 圆锥曲线即二次曲线，它的中心、直径、渐近线等概念在欧氏平面解析几何中已给出过定义、在射影几何中又给出一种新定义，本文主要利用配极变换证明两种定义的等价性，并且举实例说明根据射影几何中定义可找出较方便的计算公式。

| Abstract: | Circular cone curve,-that is quadratic curve,ellipse,hyperbola,parabola.The concept of its center,diameter conjugate diameter has been given a definition in the Oushi planeAnalytical Geometry.It has also been given a new definition in the Projective Geometry.Thisarticle shows mainly that the two definitions are equal with Polarization.It can also find amore convenieat calculative formula.according to the definiton of the projective geometry. |
