使用高灵敏度的Ｇ８５６、ＤＴＺ２ 型核子旋进式磁力仪，对乌鲁木齐地磁台１９９ 个测点的磁场梯度进行了复测。经过严格的数据校正处理，重新作出了ΔＦ等磁力线图，并分析讨论了台站院内环境磁场的变化特征。测量结果表明：乌鲁木齐地磁台仍处于磁场正常区，工作环境符合《地磁台站观测规范》要求。
The magnetic field gradients of 199 measuring points in Urumqi geomagnetic station were retested using the highly sensitive G856 and DTZ2 nuclear precession magnetometers. After rigorous data correction processing, we re-made the magnetic flux lines such as ΔF, and analyzed and discussed the change characteristics of the ambient magnetic field in the station yard. The measurement results show that the geomagnetic station in Urumqi is still in the normal magnetic field and the working environment meets the requirements of the “Geomagnetic Observatory Specifications”.
