| 摘 要： | 通过深入研究均匀半空间瞬变电磁法解析式迭代法的特点，总结出“龙格”多解和系统受噪声污染产生的多解在物理表现形式上是统一的，因此引入随机共振算法来消除“龙格”多解现象。试验结果表明，此反演方法有效地解决了TEM全区视电阻率迭代算法反演时的多解现象，并且具有较高的反演精度。

| Abstract: | Through investigating the characteristics of analytical iterative method for homogeneous half-space TEM, it is concluded that the “Runge” multiple solutions is in the same physical form with that generated by systems noise. Hence, the stochastic resonance algorithm was introduced to eliminate the “Runge” multiple solutions. The results showed that the proposed inversion method was effective in solving the multiple solutions in inversion calculation of iterative algorithm of TEM all-time apparent resistivity with high retrieval accuracy. |
