An optimal solution, which is a trueamplitude, is obtained in the process of iteration by considering the weighted factors to compensate the amplitude spreading and the Angle effects with offset.
考虑振幅几何扩散补偿、散射角度补偿，在迭代反演过程求出最优解，即保幅偏移解。

If you take a spring, it is true that the period of oscillation is independent of the amplitude but only up to a point.
如果用弹簧，周期的确和，振幅无关，但也只是点到为止。

The studying results show that the classical elastic wave equation of spherical wave is only true for fixed amplitude phase and described only kinematic equation of phase velocity.
