摘要
针对牛顿力学框架的两大疑难,结合朗格惯性系的定义,从理论上分析了星球参考系与质心参考系,并指出了在什么条件下它们可以充当惯性系.
By discussing on star frame of reference and center-of-mass frame of reference,the conditions that star frame of reference and center-of-mass frame of reference are inertial frames,are indicated.Two doubts about the system of Newton＇s mechanics are resolved.
