摘　　要：为探索数字化观测资料的前兆异常特征,进一步认识其映震能力,使得数字化观测资料在今后的地震分析预报中得到充分的利用。运用山西临汾中心地震台SSQ-2I石英摆、VS垂直摆倾斜仪、VP1、VP2宽带倾斜仪、水管仪、伸缩仪(侯马)的数字形变资料,用常规分析方法:形态法、矢量图分析总结了2010年10月24日河南4.7级、印尼苏门答腊7.3级地震的短临异常特征。In order to learn precursory anomaly characteristic of digital observation data and its earthquake reflecting ability further, and make digital observation data used fully in earthquake analysis and prediction, short-term and imminent anomaly characteristics of the Oct. 24, 2010 Henan earthquake of M4.7 and the Sumatra, Indonesia earthquake of MT. 3 are summarized by using normal analysis methods , such as shape method and vector graph analysis, based on the digital deformation data of SSQ-2I quartz pendulum, VS vertical pendulum tihmeter, VP1 and VP2 broadband tiltmeter, water tube tiltmeter and extensometer（ Houma Seismological Station） of Linfen, Shanxi, Central Seismological Station.
