摘要
针对南京地震台地电场无斜道测量的布极方式,从地电场的矢量特性着手,经过对观测数据的分析,认为目前普遍采用地电场斜道观测的方式可以取消,增加NS测道和EW测道的测量,加大地震前兆数据的采集,为地震预报提供更多的前兆观测数据。
In this paper, initiating the research on vector features of geo-electric field, the electrode layout mode in Nanjing platform, which is without an oblique measure line, is studied. Based on the analysis of observed data, it is found that the oblique measure line used widely in geo-electric field observation can be abrogated. Meanwhile, increasing the measurement on NS and EW lines and the acquirement of earthquake precursory data would provide more precursory observation data for the earthquake forecast.
