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 instantaneouscenterofrotation.
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。

The two different definitions of the axis ofrotation are discussed. One is the definition of the CIRP text and the other is that of the instantaneouscenterofrotation.
