| Abstract: | Based on the basic principles of mechanics the reasons of speed changes when and after the ball touches the table during loop drive were approached. In the light of the speed change phenomenon after the ball touches the table during loop drive, according to the principles Of mechanics and collision, the speed changes when and after the ball touches the table and the flying radian of the ball were deducted theoretically. The reasons of the change of the curve of the loop were related briefly from the basic principles of hydrodynamics and the three aspects -r >Vc, r = Vc, r
