摘要
利用蒙城地震台近20年的地磁Z分量观测资料,对磁静日幅度、磁扰日幅度和磁静日低点时间的年变化与长期变化进行了分析,结果表明,Z分量日变化特征明显。由此总结出Z分量变化的一些基本特征,对识别地磁场异常变化或干扰变化具有一定的参考价值。
In this paper, using geomagnetic Z-component data in Mengcheng Seismic Station nearly 20 years, we analyzed the amplitude and low-point time of magnetically quiet day and the amplitude of magnetically disturbed day′s annual variation and long-term changes. The results showed that the characteristic of daily variation of Z-component obviously, so we can summarize some basic characteristics of changes in the geomagnetic Z-component. In the paper, certain value for reference to recognition interference and abnormal of the geomagnetic field is presented.
