摘　　要：在2004年12月26日印尼苏门答腊以北近海发生MS8.7两次大地震之前,华北地区小震日频次演变出现了类似震兆的信息。采用“震情三分律”的方法处理了华北地区小震活动的数据,分析认为成组震兆的出现与大震之间的遥联性绝不只是一种小区域性的现象,而是一种大范围的普遍现象,大地震是全球性的震动,其震动遥联性的显示,就必然是跨越全球性的。讨论这种现象的物理意义目的在于识别和判断这种震兆的特性,对本区今后的地震活动趋势预测工作有所借鉴。The daily times of small earthquakes in Huabei region appear similar seismic precursor information before the 2 Ms8.7 earthquakes in Sumatra island, Indonesia on Dec. 26, 2004. We use the earthquake situation trichotomy method to deal with the datum of small earthquakes in Huabei region, the result shows, the relativity between group seismic precursor informaitons and large earthquakes is rifeness phenomenon of large area, the shake of large earthquakes are globality, the remote correlation of shake are globality. The intent of discussing the phenomenon is to distinguish and determine the characteristics of the seismic precursors, and help earthquake prediction in the region.
