摘要
地磁相对记录中,雷电干扰在全国范围普遍存在,但干扰原理尚未明了,给仪器的日常维护和数据预处理带来困惑。以蒙城地震台2009—2010年两套GM4磁通门磁力仪记录的数据为基础,针对该类干扰现象进行对比分析,并对其形成原理进行探索。
The thunderbolt interferes with the relative geomagnetic records is common in our country. But because its principle is not yet clear, we have some confusion in our equipment daily maintenance and data pretreatment. In this paper, we have compared and analyzed the data, that record the results of two sets of GM4 fluxgate magnetometer at Mengeheng Seismic Station from the 2009--2010, for exploring the principles of the thunderbolt interference.
