论文摘要
通过比较运动的微分方程，讨论了引力和线性弹性中央保守力场的两体运动。两种力类型的反向和直接方位移依赖性显示为轨迹中出现的。讨论了该轨迹的封闭（对于重力场）和开放（对于特定的哑铃弹性系统）特征。
The two-body motion for the gravitational and linear elastic central conservative force field is discussed by comparing the differential equations of motions. The inverse and direct square displacement dependency of the two force types is shown as emerging in the trajectories. The closed (for the gravitational field) and open (for the particular dumbbell elastic system considered) character of the trajectory is discussed.
