A study of computations for acoustic velocities of arbitrarily dipping layers

Through deriving expressions relating the dip-angle (φ_m) of the lower boundary of a rayer to the acoustic velocity (V_m) of the layer and other predetermined parameters, V_m and φ_m can be taken as simultaneously iterative variables in solving shah's equations. Consequently the previous method¹ of computing V_m and φ_m presented by Zhang S. is improved with better accuracy of computations.
