为进一步了解河北黄壁庄地震台新磁房FHD的运行情况,对观测数据的断记、观测干扰、地磁趋势变化、空间相关、差值相关等进行分析,结果表明观测数据在完整性方面比较好,数据受干扰程度较小,可靠性比较高,但是背景噪声偏大,数据精度有待提高。
In order to further understand the operation of the new magnetic room FHD in Huangbizhuang Seismic Station of Hebei Province, the analysis of the observed data, the observed interference, the change of the geomagnetic trend, the spatial correlation, the difference correlation and so on are conducted. The results show that the observed data are better in integrity, Less interference, reliability is relatively high, but the background noise is too large, the data accuracy needs to be improved.
