涉县地震台FHD矢量磁力仪记录室建设要点

The construction experience of observation chamber for FHD proton vector magnetometer in Shexian Seismic Station

涉县地震台在2005年建成了符合《地震及前兆数字观测技术规范（电磁观测）》（中国地震局，2001）要求的地磁FHD相对记录室。本文描述了从观测场地清理，到选定磁房位置，从建材选择，到建成符合标准的地磁相对记录室的建设过程，总结了一些需要掌握的技术要点和心得及经验，希望为其他台站的地磁记录室建设起到一定参考作用。

According to the geomagnetic observation rule, a record chamber for geomagnetic observation has been built at Shexian Seismic Station in 2005. We got some experience and technique during cleaning up the observation ground, choosing location of geomagnetic station and construction materials. Some suggestions about construction geomagnetic record chamber are provided for other stations in this paper.
