维普资讯 http://www.cqvip.com l2 国际地震动态 2008拄 A Suggestion on Monitoring Geoelectric Precursors in the Earthquake Risk Region in Sichuan and Yunnan Province Qian Fuye and Zhao Yulin (Institute of Geophysics,CEA,Beijing 100081,China, e—mail:zhaoy1522@yahoo.com.cn) Abstract This work was one of the two unpublished reports submitted to CEA in 2003.Ac— cording to the intermediate—term precursors of geoelectirc resistivity observed at the MN station(with DDC一2 instrument)and other reliable stations,the maximum principal stress direction was deter- mined.0n which we suggested that an earthquake with M:8 or greater would took place within 200 —300 km from MN station in 2~3 years. In order to solve the problems of instability of electrode polarization,the interference of natural electromagnetic field.and especially the interference of random electirc current due to industrilaiza— tion,the PS一100 anti—interference,high—precision geoelectric measurement system has been applied, SO as to search HRT wave with short—term or impending precursors. Key words the reliable intermediate—term precursors in geoelectric resistivity;the electric (magnetic)interference problems in observation;the PS一100 anti—interference electrical observation svstem:the HRT wave model;search for HRT wave with short—term or impending precursors 中国地震学会 空间对地观测专业委员会名单 许绍燮 王希季刘振兴马宗晋马瑾陈鑫连钱家栋丁鉴海赵国泽 申旭辉 主 栾毅 吴云 顾行发 单新建曹晋滨 吕苑苑 洪顺英 荆风 方广有 王兰炜 王晓青 王海涛尹京苑邓志辉卢军卢红刘放 刘玉荣 朱涛 乔晓林 李丽李炳乾吴健吴立新杜瑞林杜学彬 杜爱民 余涛 余书明 苏有锦汤吉杨冬梅杨芳陈化然孟国杰 孟庆岩 张学民 张吉龙 张元生张晓东张永仙张景发张润宁张贵霞 范一大 金红林 侯建盛 赵树贤赵谊徐京夏善红秦其明唐伶俐 康小林 康春丽 黄剑涛 路立焦明若
