江苏地区地电阻率各向异性度分析
|
摘要
应用地电阻率各向异性度S值计算公式和程序，对江苏地区4个地电台1980～1997年的地电阻率各向异性度S值进行了计算研究分析。 结果表明，S值这一新的电性参数在江苏南黄海2次6级以上地震前存在异常变化。 地电阻率各向异性度S值可以作为一种新的电性参数应用于地震综合预报研究。 在讨论中对S值的定义提出改进的公式，与同仁商榷。
Calculation study and analysis is made of the anisotr opy degree of ear th resistivity(S-value) for 4 geoelectric stations in Jiangsu area during the p e riod of 1980～1997，using the calculation formula and program of the anisotropy degree of earth resistivity S. The results show that anomalous variations appea re d in this new electrical parameter S prior to the 2 Southern Yellow Sea earthqua kes of magnitude above 6. The anisotropy degree of earth resistivity S might be a pplied into the research of combined prediction of earthquakes as a new electric parameter. An improved formula for the concept of S is suggested in the discus sion section for the purpose of discussion with colleagues.
