COMPARISON OF DIGITAL AND ANALOGUE GEOMAGNETIC DATA IN CHANGLI SEISMOSTATION

    摘要
  • 摘要: 利用模拟仪和GM3磁通门磁力仪、FHD-1核旋仪对2002年、2003年的数据进行了日值差值比较、基线值及其精度分析、极大极小值相关分析, 探讨模拟仪与数字仪存在的差异及原因, 得出数字仪产出资料的内在质量高低和影响数据质量的主要因素, 得出数字仪改造是成功的, 在观测技术不断完善的将来, 数字仪是完全能代替模拟仪的。

     

    Abstract: The digital geomagnetic data recorded by GM3 Gaussmeters and FHD-1 Nuclear precession Magnetometers in 2002 and 2003 are compared with the analogue data.The baseline value and its accuracy as well as the correlation between maximum and minimum are analyzed.Through studying the difference of analogue and digital data and its cause, we find out the main factors that affect the quality of the data.It is concluded that digital observation can replace analogue observation.
