摘　　要：应用相对运动反转法及运动链矢量环路方程,导出了确定平面机构中任意2个构件之间的相对运动瞬心位置计算式。并由此推出瞬心速度、瞬心曲线、加速度瞬心的解析计算式,证明了三心定理是该计算式的特例。By applying the kinematical reverse revolving method and vector loop equation of kinematical chain, the formula for determining the positions of instantaneous centers of relative motion between two optional components in planar mechanism was derived. And in view of this the analytical formulae for velocity of instantaneous center, curve of instantaneous center and instantaneous center of acceleration were deduced. It has been verified that the three-center theory is a special case of that formulae.
