摘要
在关联维数的基础上,对局部导体的瞬变电磁法信号分形特征进行了研究.瞬变电磁响应电位异常(包含有一定干扰)有明显的分形特征;对尺度ε的选取进行了讨论,应根据瞬变电磁异常响应的分形体特点进行细致分析,才能得出尺度ε的合理取值范围.实际应用结果表明,利用分形理论解释瞬变电磁资料,可为减少成果解释的多解性提供帮助.
The fractal character of TEM signal is studied on the basis of correlation dimension. The result shows that TEM response potential （with some disturbs） presents the evident fractal character. In the discussion of selecting the scale e to get a reasonable scale e rang, it should be based on the detail analysis of TEM response potential fractal feature. The application proves that it is helplul to reduce multi-interpretation of TEM data, with the fractal theory.
