摘要
采用简捷的方法推导质点系相对于任意动点的动量矩定理，并由此引出质点系相对于质心的动量矩定理和质点系相对于速度瞬心的动量矩定理．
In this paper, the principle of the angular momentum of a system of particles about a moving point is developed briefiy. There from it is used to obtain the principles of the angular of momentum of the system of particles with respect to its cenier of mass and instantaneous center of velocity.
