相切于定三角形三边的二阶曲线的伴随点及其分布

A Adjoint Point of a Quadratic Curve Which Contact Three Side of a Fixed Trangle and Its Distribution

证明了相切于定三角形三边的二阶曲线与三角形三边所在直线外的点(伴随点)一一对应,并得出各类型伴随点的分布情况.

In the article, it has been proved that the quadratic curve which contact three sides of a fixed trangle is corresponding to a point （adjoint point） which out of the three lines about the sides of the trangle. And puts the distribution of all sorts of adjoint points.
