| 摘 要： | 南黄海海域６．１级地震发生前，对海安台Ｎ３０°Ｗ、Ｎ７０°Ｗ、Ｎ６０°Ｅ三组测向和南京台ＥＷ向测向地电阻率负异常时段进行了３１日低通滑动平均滤波计算，发现异常突出，并超过二倍中误差，经分析认为对地电阻率所出现的中长期异常时段，不能轻易否定，必须不断跟踪分析

| Abstract: | The geoelectric resistivities of negative anomalous interval of three component consisting of N30°W, N70°W and N60°E of Haian station, and E-W one of Nanjing station before the South Yellow Sea earthquake of M s 6.1 were analysed using the filtering calculation for lowpass moving average of 31 day. It is shown that anomaly is so obvious that exceed double mean square error. It is considered that this is long medium term anomaly which is simply not denied and necessarily traced. |
