| 摘 要： | 德都地震台从2006年4月25日开始进行台站的数字化改造，改造的主要内容是进行地磁绝对观测室的建设和地磁相对记录室的建设。众所周知，地磁观测用房建设难度大，而难度大主要来自地磁观测场地和地磁观测设施的磁性是否合格。本文就是对德都地震台建设地磁房期间有关磁性检测和检测结果的介绍。利用G856磁力仪和CTM-DI磁通门磁力仪，进行野外和台站的材料磁性检测，方便、快捷、准确，是保证地磁观测用房建筑材料磁性合格的好方法。

| Abstract: | The Dedu Seismic Station starts began digitalization reconstruction since Aril 25, 2006. The primary target is to build the earth magnetism absolute observation room and earth magnetism relative recording camera cabin. It is well known that the geomagnetic observation room is difficulty to build for the high standard of the magnetic quality of the observation site and the observation facilities. In this paper, the magnetism examination and its results car- ried out during the construction of geomagnetism observation room in Dedu Seismic Station are introduced. Using the G856 proton magnetometer and the CTM-DI magnetic fluxgate magnetometer, the field and the station material magnetism examination can be carried out conveniently, quickly and accurately. This method guaranteed the magnetism quality of the materials used in building the geomagnetic observation room. |
