海安地震台新场地的地电阻率广播干扰确定与排除

Determination and elimination of the interference on resisitivity observation caused by countryside broadcast at Hai′an new geoelectric station

海安地震台新场地的地电阻率观测于2004年12月初步建成,在试观测期间发现地电阻率东西测向观测数据严重受农村广播干扰,这种干扰国内未见报道,本文初步分析和总结了这种干扰的特征、产生机理及干扰排除措施,对其他台站建设地电阻率观测台站有一定的指导意义。

Resistivity observation at Hai＇an new geoelectric station began in early December 2004. During the testing observation period, we found that there was serious interference from special countryside broadcast. For this kind of interference has never been reported, we have primarily analyzed and summarized the feature and mechanism of the interference, as well as the methods for removing it. The results are of instructional significance for the geoelctric resistivity observation on other stations.
