| 摘 要： | “九五”地震前兆数字化台站改造后，数字化的地磁观测仪器在全国各地磁台站推广应用已有两年多时间，两年来，数字化观测仪器和模拟记录仪器在武汉台一直进行并行观测工作，其观测资料稳定可靠。本文通过GM-3磁通门磁力仪与其它仪器进行数字和模拟观测资料的时均值、日均值、月均值、年均值对比分析。分析结果表明数字观测资料优于模拟观测资料，数字观测仪器完全可以取代模拟观测仪器。

| Abstract: | The digital instruments have been used in the most geomagnetic stations in China for two years after the digitalized rebuild during the 9th Five-Year Plan.The combined observation of digital and simulated records had been performed for two years in Wuhan seismic station.Their observation data are stable and reliable.We have comparatively analyzed the hourly means,the daily means,the monthly means and yearly means for the GM-3 fluxgate magnetometer.The results indicate that the digital records are better than simulated and the digital records can completely replace to the simulated geomagnetism records. |
