摘　　要：本文对昌黎台地电场6个分量2009年全年的小时值进行了频谱分析,分析结果清楚地显示了日波动、半日波动和三分之一波动。研究人员对该台地电场EW向长极距2009年1月1日～31日的数字化观测资料进行了小波分析,提取到了地电场固体潮半日波和周日波。昌黎台利用铅电极进行地电场观测,不仅观测到了磁场的相关信息,并能较好地观测到潮汐响应,这在全国是首例。In this paper, the hour values of six geoelectric field components, which recorded at Changli Seismic Station in 2009, have been separately analyzed by spectrum analysis method. And the diurnal, semidiurnal and one third day wave of the earth tide can be clearly observed. Then the digital observed data of the long electrode distance in EW direction at this seismic station were analyzed by wavelet analysis from January 1st to 31st, 2009.The diurnal wave and weekly wave of the earth tide were extracted. This is the first case that the geoelectric field observation using the lead electrode can not only detect the information about the geomagnetic field but also observe the earth tide.
