摘　　要：详细介绍了 1996年 11月 9日南黄海 6 1级地震前 ,巢湖地下水动态观测网中 3口水井所记录到的水位经标准差、剩余值数据处理得到的前兆异常。其异常时间以中短期为主 ,不同步。此外还对降雨对井水位的影响以及如何提高地震预报的准确性等问题进行了讨论。The precursory anomaly of the south Yellow Sea of M S 6.1 on Nov.9, 1996 has been obtained using three well table record of groundwater dynamic observation network in Chao Lake through statistic processing. Their anomalies are mainly short medium term, and not synchronism. Finally, some problems of how to enhance the accuracy of earthquake prediction and the effect of rain to well table are discussed.
