角动量定理的一个推广

A GENERALIZATION OF THE ANGULAR MOMENTUM THEOREM

本文将角动量定理推广到了以瞬心作为矩心的情况。结果表明，与通常的角动量定理比较出现了修正项。文章还进一步讨论了修正项不出现的条件。

A generalization of the angular momentum theorem in the classical mechanics has been derived in the case that the instantaneous center of rotation is taken as the center of moment.It is shown that there will be a revisional term in the generalized angular momentum theorem.Furthermore,the conditions,in which the revisional term will disappear,are still discussed.
