摘要
本文研究一种新的反演方法，即数值正演模拟与全局优化法相结合的非线性数值反演方法。方法中用傅里叶变换法进行数值正演，全局优化法则利用了遗传算法。该方法的优势在于可以适用于各种不同的具体问题。文中在阐明了基本原理之后，就一维波动方程系数的反演作了试算，得到了预想的结果，从而说明了方法的有效性。
Nonlinear numerical inversion of seismic elastic parameters, a new method, is recommended here, which combines forward numerical modeling with overall optimization. In the method, the forward numerical modeling is achieved by Fourier transforrn, and the overall optimization by hereditary algorithm. Particularly, the method is applicable to some different problems. This article describes its basic principle and coefficient inversion of one-dimensional wave equation. Satisfactory result proves the method effective.
