| 摘 要： | 本文将Jones的蒙特卡罗反演法,与修改后的马夸特反演法有机地结合在一起,从而获得了一种新的蒙特卡罗反演法.它实际上是定向求解与随机求解的结合,具有占用机时短及解的拟合度高的优点.作者利用该法处理了理论视电阻率曲线,及实测的视电阻率曲线,获得了大量具有高拟合度的模型,进而获得了可能解的范围.

| Abstract: | In this paper,we combine the Jones' Monte Carlo inversion method with revised Mar-quardt inversion to get the new Monte Carlo inversion method. The method has advantages of high calculation speed and high precision of solution. It is actually a combination of random solution and directive solution. The authors processed the theoretical apparent resistivity data and actual apparent resistivity data using the new Monte Carlo inversion program,and a large number of models with high fitting degree,therefore obtaining the range of solution. |
