摘　　要：在分析唐山7.8级地震前后地电阻率异常变化特征的基础上,研究地电阻率异常量△ρ_0与应变的关系,给出了地电阻率异常量△ρ_S/ρ_0对应变ε的转换关系式;分析和研究地电阻率异常发展、演变特征与地震孕震、发生过程的联系及其前兆异常标志。In this paper the relation between anomaly quantity of earth resistivity and strain is derived through analyzing the features of geoelectrical anomaly variation around Tangshan earthquake (Ms = 7.8)and the transfer relation between earth resistivity anomaly quantity and strain is given. Besides, the relation between development and evolution of earth resistivity anomaly, development of earthquake and occurrence process, as well as the index of precursory anomaly are also studied.
