摘要
以汤川核力场为例，说明用有效势方法讨论有心力场中圆形轨道的稳定性，数学处理比较简明，物理图象也比较清晰。进而指出非径向微扰引起的速度矩变化对稳定圆轨道半径ｒ＿０的影响，导出两者变化的数量关系，说明在汤川核力场中维持稳定圆运动对微扰量所加的限制。
The stability of the trajectory of circle motion in a centripetal potential,in particular,the YuKawa one , is discussed by using the effective potential method which has the advantage insimplicity of mathematical treatment as well as in clearness of physical meaning。 On the stabilityof the circle motion,the effect of a change of the angular momentum caussed by a non-radialperturbation is pointed out,and a constraint condition for the perturbation, which does notviolate the stability of that motion in YuKawa potential, is given。
