摘　　要：为提高野外CSAMT测深数据的反演解释效率,提出了将并行计算技术引入CSAMT测深一维自动迭代反演中进行CSAMT拟二维反演解释的思路,基于多处理器多核工作站,结合多进程和多线程并行编程技术,形成相应并行算法和程序。采用该并行计算方法进行实测数据反演解释,结果表明,CSAMT拟二维反演解释并行计算技术能较大幅度地提高CSAMT测深数据的反演解释效率。In order to improve the efficiency of the inversion of CSAMT sounding data,this paper suggests that parallel computation should be introduced into the 1-D iterative inversion of CSAMT sounding data for pseudo-2D inversion interpretation.Based on multiprocessor and multi-core workstation and using the programming technology of multithread and multi-process,the authors formed the parallel algorithm and the final program.The parallel algorithm was adopted for inversion interpretation of measured data,and the result shows that the pseudo-2D inversion using parallel algorithm can greatly improve the efficiency of the inversion of CSAMT sounding data.
