密切关联于反射的是斜反射和圆反演。
Closely related to reflections are oblique reflections and circle inversions.
圆的反演:反演成一圆。但当圆通过反演中心时变成一直线。
Inverson of circle: Into a circle, if the circle pass through inversion center o, it becomes a straight line.
在有心二次曲线的反演定义、变换式的基础上,推导出此种反演变换的一些性质,通常的关于圆的反演的性质可作为它的特例而得到。
In this paper, we discuss some properties of the reversion for central quadratic curve on the basis of general reversion definitions and its transformations.
