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。
通過對2006-2011年寶應模擬電磁擾動鑑測範圍內3-4級地震前異常變化的時、空、彊的特徵統計和分析,認為寶應模擬電磁擾動儀器具有較好的地震短臨預測能力,歸納儀器的異常通道、異常起始時間、最大振幅變化和異常頻次與地震間的特徵聯繫,併對震例中齣現的特殊情況進行探討,認為未來在立足觀測的同時,還需根據儀器所處的地質和地震情況,綜閤其他觀測手段開展地震預測研究工作。

Based on statistics and analysis on the temporal,special and strength charactirstics of ana-log 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 ampli-tude 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.
