【摘要】 利用河北省5个地磁台站2004—2013年数字化地磁资料进行转换函数计算,对河北不同地区的计算结果进行分析及对比。结果表明,不同地区地磁转换函数具有不同变化趋势,且同一地区不同深度的转换函数变化也不同;地磁转换函数变化和地震具有明显联系,主要表现为地震发生时转换函数不同周期段会发生较为明显的变化。更多还原

【Abstract】 Using the digitized data of five geomagnetic stations in Hebei Province from 2004 to 2013,we calculated the geomagnetic transfer functions and analyzed them. The results showed that the geomagnetic transfer functions in different regions have different trends and the same changes at different depths in the same area. We also found that the geomagnetic transfer functions had a relationship with earthquake, some bands would show obvious changes when the earthquake occurred.更多还原
