补充资料：有心力场
| 有心力场 central-force field 质点所受力的作用线恒通过一固定点，且其值为两点距离的函数的力场。该固定点称为力心。一个质点、一个均匀球壳或一个密度为到球心距离的函数的球体在空间产生的引力场都是有心力场。有心力场在研究行星和航天器的运动以及电子和a粒子在核电场中的运动中有广泛的应用。有心力场的一个重要性质是，质点对力心的角动量守恒，所以质点轨迹是平面曲线，且质点矢径扫过的面积速度（矢径在平面上单位时间扫过的面积）守恒。行星在太阳系中所受太阳的巨大引力远大于其他行星引力之和，故可近似地认为行星在以太阳为力心的有心力场中运动。质点在有心力场中的运动满足比奈公式：  ，式中m为质点的质量；C为面积速度的两倍；u＝1／r，r、 j为极坐标；F为质点所受的有心力，负号表示在引力作用下，正号表示在斥力作用下。用此公式，可由质点运行轨道求其所受的力，也可由力求运行轨道。 |
