【摘要】 讨论了弹性水平层状介质中ＳＨ波的反演问题。在平面脉动ＳＨ波激励和反射模式下利用传递算子方法逐层反演了介质的速度、密度和厚度，反演过程转化为线性回归，并且进行了数值模拟，这种逐层反演方法简化了方程的阶数和计算量。更多还原

【Abstract】 The inverse problem of SH wave propagation in horizontally stratified elastic medium is discussed in this paper. The medium velocity, density and thickness are inversed layer by layer using arrangement and combination and transfer operator technique in the plane pulse SH wave source excitation in the reflectivity method. The inverse progress is transformed a linear regression. The numerical simulations are performed. The inverse method of layer by layer cuts down equation rank and calculation quantity.更多还原
