摘　　要：主要采用一阶差分、滤波、五日均值等方法,分析处理了泾阳地震与宝鸡地震前后临潼台流体资料,从中提取出了明显的短临前兆异常,对这两次地震前流体异常幅度及异常时间进行了比较,并且对异常原因进行了分析和讨论。By using the methods of first order difference, digital filtering, 5-days-mean and etc., we analyzed the underground fluid data recorded before and after the Jingyang and Baoji earthquakes at Lintong Seismic Station and found the obvious short-impending precursor anomalies. We also compared and discussed the anomalies of both earthquakes.
