| 摘 要： | 经对地电阻率ρs观测值的分析研究,发现观测数据因受本身台址电性条件的限制,观测深度较浅,受降雨等气象因素的影响明显.运用合肥地电阻率北南、北西向2007-2013年观测资料月均值与温度、降水、地下水位进行相关分析,采用多元线性回归方法对地电阻率进行校正,以反映地电阻率的真实变化,达到提取地震异常的目的.

| Abstract: | Through analysis and research on the electrical resistivity Ps value, fund observation data were limited by the electrical conditions at the seismic station, the observation depth is shallower, and the data were affected by rainfall and other meteorological factors obviously. The interrelation among the monthly mean values of 2007 -2013 NS, NW resistivity,precipitation and underground water is analyzed in Hefei seismic station. the resistivity is corrected by using the multiple linear regression in order to reflect the real variation of resistivity, and to get seismic anomalies. |
