| 摘 要： | 简要介绍了几种被广泛应用的非线性方法：（１）非线性方法在相交物探信息闭合中的应用；（２）非线性Ｒａｄｏｎ变换在波场分离中的应用；（３）非线性Ｋ－Ｌ滤波在提高地震资料信噪比中的应用；（４）非线性方法在剩余静校正中的应用；（５）利用三阶弹性常数建立非线性波场方程。通过对照可以明显看出，通常情况下非线性方法的效果要比线性方法的效果好一些，也就是说非线性方法具有线性方法没有的许多优点。

| Abstract: | In this paper, several extensively applied nonlinear methods are simply introduced to our readers:(1)the application of nonlinear methods in the closure of intersecting geophysical information,(2)the application of the nonlinear Radon transforms in the separation of wave field,(3)the applying nonlinear K-L filtering to improve the s/n ratio of seismic data,(4)the application of nonlinear methods in the residual static correction,(5)the establishment of nonlinear wave field equation by use of third order elastic constant .It is obvious by comparison that nonlinear methods have a better effect than linear method in general. |
