摘要: 从行星绕日运动的面积速度守恒出发,通过计算行星位矢的掠面面积,得到轨道上任意两点的运动时间及椭圆轨道上的周期.

关键词: 圆锥曲线轨道, 开普勒定律, 有心运动, 面积速度, 离心率

Abstract: By means of calculating the constant area velocity of a planet moving in the conic curved orbit and the area which the position vector sweeps past, the time between any two points and the period in an elliptical orbit are obtained.

Key words: conic curved orbit, Kepler laws, central movement, area velocity, eccentricity
