摘要

采用滤波、拟合、去周期、五日均值等方法,对临潼台水氡、水温、水溶气资料进行了分析处理,得到以下认识:用提取异常方法对原始曲线进行处理后,地震前兆异常更加明显与突出,这些异常均属于短期和临震前兆异常;临潼台流体对2003年山西洪洞ML5.0地震有明显反映,其原因一方面由于此次地震距临潼台较近,另一方面也反映了临潼台所处构造位置比较特殊,位于映震的灵敏位置。
Water radon,water temperature and water-dissolved gas data of Lintong Seismological Station have been processed and analyzed the means of digital filtering,fitting,period removing and average 5-day value etc.The conclusions have been made as followings: Precursory anomalies are more obvious and prominent,which all belong to anomalies of short term and imminent term,after anomalies are distilled from the raw data;Fluid of Lintong Seismological Station has obvious response to the Hongtong earthquake of M_L5.0,one cause is that the earthquake is near to Lintong Seismological Station,and another is that Lintong Seismological Station lies on special geological structure sensitive to the the earthquakes.
