摘要
对阳原台１９７９年４月至１９９２年６月的ρ＿ｓ月均值，用差值法消除年变以后，突出了正常背景和异常特征。得出消除年变后的ρ＿ｓ月差值，反映台站２２０ｋｍ内５级以上地震的效果是好的结论。
After eliminating yearly variation to ρ_3 monthly mean values from Yangyuan station during 1979-04～1992-06 by the difference method,the normal background and the anomalous characteristics emerged.Theanalytical result shows thatρ_3 monthly differences with M≥5.0 in 25 km range around the station obviously.
