摘要
文献［１］Ｐ．２２０～Ｐ．２２５中给出了二阶曲线的主轴、焦点与准线的概念及一些初步的结论。本文在此基础上，在复仿射平面上分无心型、中心型两种情况不同于［１］而从图形的角度利用完全四点形一般性地探讨二次曲线主轴、焦点、准线三个度量概念，作为对文献［１］的补充。
There are some concept and concise conclusion about major axis, focus, directrix of conic in literatureP.220-P.225. In this paper we use the figue and complete fore-point general to discuss the metric property of conical section in complex affine plan. The method in this paper is different literalure. The conclussion of this paper is supplement about literature.
