摘　　要：地磁台是定点获取地球磁场及其长期变化数据最有效的观测手段之一,地磁台选址及地磁观测仪器对磁场环境,如静态磁干扰、事件型磁干扰、短周期磁干扰等有极高的要求。本文棍据dIdD磁力仪的构造特点和工作原理,设计并进行观测试验,分析dIdD磁力仪运行期间对不同距离的磁场环境产生的影响。结果表明,距离≥3m时,影响可忽略不计。试验结果可作为dIdD磁力仪在地磁台安装运用的参考。The geomagnetic observatory is one of the most effective methods for acquiring the Earth's magnetic field and long-term variation data.The siting of geomagnetic observatory and magnetometer has high requirements for electromagnetic environ- ment,such as static magnetic disturbance,incident magnetic disturbance and short-period magnetic disturbance.According to the structural feature and working principle of geomagnetic observatory,the experiment is designed and carried out to analyze the effects of dIdD magnetometer to the electromagnetic environments in different distances at runtime.The results show that the influences can be neglected when the distance is more than 3m,which can be used as the reference of dIdD magnetometer installation in the magnetic observatory.
