| 摘 要： | 通过分析山西5个地电场观测台站的弱大地电场日变化现象,认为其与电极的稳定性密切相关,这在代县台、临汾台、夏县台大地电场中表现比较明显;其次背景噪声大是造成山西大地电场弱日变的另一主要原因,这在大同台、太原台大地电场表现比较明显。此外,山西大地电场弱日变化与各台地下电性结构、季节变化等因素有密切的关系。

| Abstract: | Through analysis on weak daily variation in geoelectric field of 5 observation stations in Shanxi,we conclude that this phenomenon is closely related to the electrode stability,which behaves obviously especially in the geoelectric field of Daixian,Linfeng and Xiaxian stations.The strong background noise is another main reason resulting in weak daily variation in Shanxi,especially for geoelectric filed of Datong and Taiyuan stations.In addition,the weak daily variation in geoelectric field in Shanxi is also ... |
