| 摘 要： | 由反演方程出发，从构造目标函数和方程求解方面，比较了国际上通用的OCCAM(奥可姆法)、RRI(快速松弛法)和REBOCC(简化基奥可姆法)，并由两个合成模型分析比较了OCCAM、RRI和REBOCC的反演结果。试验表明，REBOCC是继RRI之后又一种较快的反演方法，可为电法勘探资料处理提供新的途径。而在RRI和REBOCC反演时，网格的划分对结果很有影响，这是值得注意的地方。

| Abstract: | Firstly, we review several general methods of two-dimensional magnetotelluric inversion in the international such as OCCAM, RRI and REBOCC from the inverse equation, then compare the objective functions and solving methods. And we compare the inverse results of OCCAM, RRI and REBOCC through two synthetic models. Numerical experiments show that REBOCC is a fast inverse method, which will provide a new and fast approach for the processing of electrical exploration data. However, when using RRI and REBOCC, it should be concerned that the grid will affect the result. |
