| 摘 要： | 利用乌什地震台数字大地电场分钟值资料,分析了各方向、各测道的日变形态及特征,对干扰大地电场数据变化的一些因素进行分析。在数据未受到干扰时,电场数据会出现双峰双谷日变化,能够清晰地记录到电磁暴。受雷电的影响,电场数据会出现尖锐的突跳。电极坑周围渗水会影响数据质量,造成向下和向上交替突跳,形成方波状干扰。

| Abstract: | The author analyzed the daily variation shape,characteristics and some interference factors of digital geoelectric field data in Wushi station.When the data was interfered,there would be daily variation shape with 2 peak-valley variation and electromagnetic storm.Because of thunderbolt influence,there would be keen-edged sudden change.The data quality would be affected and showed alternately sudden change and quadrate wave interference. |
