采用切线坐标的比耐公式

BINE' S FORMULA IN THE TANGENT COORDINATION

本文采用切线坐标，推导出了比耐公式的新形式．并用解运动微分方程的方法求得了统一的圆锥曲线的切线坐标方程．

In this paper,with the tangent coodination the new Bine's formula was deduced, and by the method of solved differential equation of motion,it was obained theunited equation about conic sections in the tangent coordination.
