| 摘 要： | 对海原台CZB-1型竖直摆钻孔倾斜仪记录到的地表倾斜方向的异常变化进行了分析，同时对该台YRY-4型分量应变仪依据自检方法表现出的压缩及伸张性异常进行了提取，得出以上两测项观测资料在宁夏南部发生的3次Ms3．0级以上有感地震的2次地震前出现了一定的异常信息，与地震赢救蚺蕴。

| Abstract: | The anomalies of the surface tilt directions recorded by CZB - 1 Vertical Pendulum Tiltmeter in Haiyuan seismic station are analyzed, and the compressed and stretched anomalies recorded by YRY - 4 Component Strainmeter are chosen, and found these data presented anomalies just before two earthquakes with Ms ≥3.0 occurred in southern Ningxia, and this shows that the data are corresponded to the earthquakes. |
