【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。更多还原

【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.更多还原
