摘　　要：通过对辽宁地区流动地磁的观测资料进行对比分析,研究探讨了影响磁测精度的各测点与通化台之间的通化距离、经度方向距离等因素对磁测精度的影响情况。为提高流动地磁观测的磁测精度提供了参考。It＇s aimed at providing a reference for improving the magnetic measurement accuracy of the repeated and temporary geomagnetic observation. Based on comparative analysis of the observation data of the repeated and temporary geomagnetic observation, the effect of magnetic measuring accuracy on the longitude distance and other factors between measuring points which are affecting magnetic measurement accuracy and stations is studied and discussed in this paper.
