The results show that magnitude of tangential velocity component of absolutevelocity is larger one order than that of radial component.
试验表明，蜗壳内部液体绝对速度的圆周分速度比径向分速度大一个数量级；

The absolutevelocity was decomposed based on the law of velocity triangle, the absolute tangential velocity, the relative velocity and the relative tangential velocity were presented in this paper.
Relative plate motion can not demonstrate the motion velocity of individual plate, while absolute plate motion can show the motion velocity in the stationary geospace.
