摘要
本文使用天津及邻近地区14个地磁台记录的地磁短周期变化资料,求出了各台的帕金森矢量。这些参数的大小反映了地下深部电性结构的横向不均匀程度。在本文涉及的区域内,帕金森矢量的异常分布与重力,电磁测深的结果相吻合。结果表明:天津及邻近地区的电性结构异常区在渤海,其它地区无明显的不均匀电性结构。
In this papar, the data of gomagnetic short period variations from 14 geomagnetic stations in Tianjin and its adjacent areas are used to obtain Parkinson's vectors for each station.The size of these perameters reflects the transverse inhomogeneous degree of subsurface deep electric structure, In the areas studied in the paper, the anomalous distribution of Parkinson's vectors is consistent with the results of gravity and electromagnetic sounding. The result shows that the anomalous area of electric structure of Tanjin and its adjacent areas is located in Bohai Sea,and in other areas there is no ebviottsly nhomogeneous electric structure.
