摘要
推导了激励电流为阶跃波形的中心回线及重叠回线装置情况下,层状大地的瞬变感应电压的余弦积分表达式,并引入一种线性数字滤波方法来评价这种振荡类型的积分。利用所建立的程序库,计算了一维层状大地模型上的瞬变电磁正演响应,对所取得的某些结果及值得注意的方面作了讨论。
The cosine integral of the transient decay voltage in a horizontally receiving loop, for central loop and coincident loop systems, placed on a horizontally stratified earth model, and driven by a step (on-off) current source, has been deduced in this thesis. An adaptive linear digital filtering method is used in the article. The forward transient response of a 1D-layered earth model can be computed. Finally, a discussion is given on some major results and problems which deserve to be noticed.
