【Abstract】 In order to explore the change of the alosorption field when electromagnetic waves are propagated in the stratum, uses eikonal equation to calculate the curvature of curved rays, and uses the method of Maximum Eutropy as inversed result. The calculated examples show that the effed of this method to get the curvature of curved rays is evident.更多还原
