摘　　要：本文用逐步缩小搜索范围的遗传算法反演一维大地电磁数据，理论模型和实测数据反演表明，结果令人满意，本文还讨论了连续变化电性层的反演问题。In the paper, we employ the genetic algorithms with gradually narrowing the searching range toperform the inversion of 1-D MT data. Theoretical models and real data inversion demonstrate that theresult is satisfactory. The inversion problem of geoelectrical models with continuous change conductivityis also discussed.
