| 摘 要： | 分析了清水李沟井与礼县石桥井汉量变化与邻近地区发生的中强地震的对应关系。发现在邻近地区发生的部分中强地震前半年左右2口井的流量开始出现上升或波动现象，异常变化的幅度最大可达3．75mL/s，对震级较小，而且距离较远的地震无明显的异常反映。2口井流量异常对5级地震的映震范围为250km，6级地震为350km，7级地震为500km。

| Abstract: | The relation between discharge changes of Ligou well,Qingshui and Shiqiao well,Lixian and mid strong earthquakes in neighboring region is analyzed.It is found that discharges of the two wells rise or undulate about half of year before part of the mid strong earthquakes in the neighboring region,with a maximum anomalous amplitude of 3.75 mL/s.There are no the anomalies of the discharges before the events with smaller magnitude relatively distant from the wells.The reflecting range of the anomalies of the two wells to M S5 events is 250 km,that to M S6 events is 350 km and that to M S7 events is 500 km. |
