摘要
从质心运动定理和相对质心的动量矩定理出发，导出了相对瞬心的动量矩定理． 通过两个例子看出。
According to theorem of motion of centre of mass and theorem of moment of momentum about centre of mass, we derive the theorem of moment of momentum about instantaneous center of rotation. Two examples indicate that some problems in plane parallel motion of a rigid body can be easily solved by using the theorem.
