摘 要: | Through deriving expressions relating the dip-angle((?)_m)ofthe lower boundary of a layer to the acoustic velocity (v_m) of the layerand other pre-determinable parameters,v_m and (?)_m can be taken assimultaneously iterative variables while solving Shah‘s equations.Consequently the previous method of computing v_m and (?)_m presented byZHANG S.is improved,and the accuracy of solutions increasedgreatly.
