摘要
为了研究瞬变电磁早期信号的特性,这里讨论了多匝线圈与单匝线圈的自感系数的关系,同时也分析了瞬变电磁线圈等效回路的暂态过程,以及多匝线圈感应电动势的响应特征。最后,得出了影响早期信号的因素,为提取早期数据的研究提供参考。
In order to study the characteristics of the early signal in TEM loop,Both self-induction formula of single coil and multi-turn coils are given.The transient process of TEM loop and the attenuation pattern of induced voltage of multi-turn loop are discussed.Effected factors on the early signal are also analyzed.The objective is to provide these as a reference for further research.
