| 摘 要： | 处理分析了2008年1~11月宁夏石嘴山和固原地震台大地电场资料,对比研究了这两个台大地电场静日变化、干扰变化及它们的频谱特性等。石嘴山和固原地震台大地电场的变化特征:①具有明显的峰谷型静日变化形态,都含有12、24、8 h等3种主周期成份;②地电暴记录清晰可见,主要以变幅增大、时间同步为特征,但两台地电暴时频谱成份存在差异;③干扰变化特征均表现为短时突跳,变幅增大。

| Abstract: | In this paper,the data of geoelectric field at Shuizuishan and Guyuan stations in Ningxia from Jan to Nov in 2008 have been processed and analyzed.Through the contrastive study about the characteristics such as magnetostatic and disturbed data of the geoelectric field at Shuizuishan and Guyuan station and their power spectrums,the conclusions have been obtained below.The magnetostatic daily variation has obvious peak-valley shape and contains 3 main periodic components of 12,24,8 hours.When the geoelectric ... |
