本文借助非法线入射的能流比研究了一种用反射系数矩阵求取弹性介质地层参数(密度,P波与S波速度)的系递推算法”。我们首先确定一个与声介质阻抗相似的层阻抗矩阵,然后推导第n+1层的层阻抗矩阵与第几层的反“射数和参数矩阵的关系,再由这个关系递推计算地下参数。文中指出,弹性介质情况不象声学情况,它允许人们用非法向入射的阻抗求层的参数;当使用下延技术时,本文这个结论对非法向入射平面波地震数据反演问题的解起着决定性作用。
In this paper, we use a reflection coefficient matrix to study the recursion algorithm for determining formation parameters (density, P-wave and S-wave velocities) of elastic media by using the energy flux ratio of incidence of the normal line. Layer impedance matrix, and then derive layer n + 1 layer impedance matrix and the first few layers of anti-number and parameter matrix relationship, and then recursively calculate the underground parameters. It is pointed out in this paper that the elastic medium is not acoustical in nature. It allows people to layer parameters with illegitimate incoming impedances. When using the delaying technique, the conclusion in this paper is decisive for solving the inversion of seismic data from an illegally incident plane wave effect.
