摘　　要：对泰安台水平摆和垂直摆倾斜仪长期观测资料进行了分析,通过对M2波潮汐因子变化和矢量图进动轨迹的分析发现,汶川地震前存在异常现象。The long-term data observed with horizontal pendulum tihmeter and vertical pendulum tihmeter in Taian station were analysed. A certain abnormal precursor abnormal phenomenon before Wenchuan Earthquake is discovered by the analysis of M2 wave tide factor variation and the precessional trace of the vector graph of the tiltmeter.
