摘要
本文以“圆锥曲线的配极象作图法”为工具详细地讨论了共焦圆雏曲线束的有关问题,发现并证明了它的几个重要性质。同时纠正了某些高等几何教科书中关于此类问题的不严密的结论。
In this paper by using the make-graph method of the polar reciprocal image of conic sections as the tool. We seriously discuss the problems of the confocal conic sections beam. We discover and prove its some important properties and point out and redress about the improper treatment of confocal conic sections beam in some higher geometry text-books.
