| 摘 要： | 系统整理分析了1983—2008年乾陵台地倾斜仪记录到的暂态异常图像，发现其与周围4000km以内6．5级以上强震有一定的对应关系。异常图像以渐变、突变阶跃、畸变及脉动为主要特征，异常出现时间为震前0-40天，主要集中在震前4天。

| Abstract: | The momentary abnormal state patterns in 1983 -2008 years of the ground incline in Qianling seismic station are analyzed, and the results show that there are related between the anomalies and strong earthquakes with Ms≥6. 5 in 4 000km. And the anomalous characteristics are mainly presented by the gradient, abrupt change order, distorted and systolic. The anomalous time will be appeared in 0 ~ 40 days before earthquakes, mainly focused in 4 days before the events. |
