摘　　要：运用CUM-AIC方法分析了聊古一井气氡浓度观测资料,发现2006年4月9日山东莘县与河南濮阳交界的濮阳ML4.6级地震前气氡浓度有异常变化,异常持续时间达10天,计算结果中的转折点对应着异常的起止时间。CUM-AIC方法优于传统的一阶、二阶统计量分析方法。The gas radon observation data are analyzed by CUM-AIC method, and gas radon anomaly was foundbefore the ML4.6 earthquake in the boundary region of Puyang and Shenxian counties on April 9th, 2006, theabnormal lasted 10 days, the turning point in the calculation corresponded to the beginning and ending time ofabnormal. The CUM-AIC method is superior to the traditional first-order, second-order statistics analysis methods.
