摘　　要：介绍了山西临汾中心地震台的台址条件及数字洞体摆观测资料的基本情况,对2008年至2010年6月间的观测资料与全球Ms>7.0、中国境内Ms>6.0以及山西省内Ms>4.0地震之间的对应关系及异常图像进行分析。结果表明,数字洞体摆观测资料可靠稳定,震前有明显的异常显示,能记录到不同方位强震的震时脉冲信号,资料具有较强的映震能力。The site condition of Linfen central seismological station and the basic situation of digital cavity pendulum observation data are introduced in this paper. In addition, the correlation between the observation data from 2008 to June 2010 and the earthquakes of Ms〉7.0 in the world, Ms〉6.0 in China and Ms〉4.0 in Shanxi, and anomalous curves in this period are analyzed. The results indicate that the observation data of digital cavity pendulum is stable and credible, exhibits obvious anomalies before earthquakes and can record coseimic pulse signals of strong earthquakes in different orientations, indicating that the data has good earthquake reflecting ability.
