| 摘 要： | 在解反射地震的非线性反问题时,目前都采用各种迭代算法(如梯度法、最速下降法及共轭梯度下降法等),并以拟合差取极小为准则.本文对这方面具有代表性的波动方程反演理论作分析评述,指出这种经典性方法的缺点和局限,以及发展非线性波动方程地震反演的方向.

| Abstract: | The least Squares optimization together with some iterative approaches, such as the gradient method, the steepest descent and the conjugate descent methods, are often used to solve nonlinear problems in reflection seismology. This paper shows a representive approach in this aspect, i.e. inversion method of the acoustic wave equation, together with analysis and comments on its draw backs and limitations, and development trend on nonlinear wave equation inversion. |
