| 摘 要： | 通过对2006-2011年宝应模拟电磁扰动监测范围内3-4级地震前异常变化的时、空、强的特征统计和分析，认为宝应模拟电磁扰动仪器具有较好的地震短临预测能力，归纳仪器的异常通道、异常起始时间、最大振幅变化和异常频次与地震间的特征联系，并对震例中出现的特殊情况进行探讨，认为未来在立足观测的同时，还需根据仪器所处的地质和地震情况，综合其他观测手段开展地震预测研究工作。

| Abstract: | Based on statistics and analysis on the temporal,special and strength charactirstics of analog electromagnetic disturbance anomalies befor earthquakes with 3-4 magnitude at Baoying during 2006-2011 years,the good impending predictive ability of analog electromagnetic disturbance instrument at Baoying is recognized.The charactirstic connection between the earthquake and anomalous channels of instrument,unusual start time,the maximum amplitude variation and abnormity frequency is summarized.Some special cases appeared in some earthquaks are also discussed here.The results indicate that the earthquake prediction study in the future needs more other integrative observation measures according the geological and seismic sitting of location where the instrument is installed. |
