摘要
本文总结了地面上铁磁性物质感应磁场现场测量结果,较详细地描述其感应磁场的分布特征。它对地磁台站的建设与环境保护,分析与排除人为干扰因素有一定的参考意义。文中还分析菏泽地震遥测传输铁塔对地磁观测的干扰情况。结果认为,该铁塔的感应磁场没有影响到地磁观测台。
This article summarizes the field measurement data of magnetic field inducedby the ferromagnetic substances on the ground, and describes the distributionfeatures of the field in detail. It provides some reference for the construction ofgeomagnetic stations, protection of environment, the analysis and elimination ofman-made perturbations. Also, we analyze the perturbation on the geomagneticobservations by a seismic telemetering transmission tower in Heze. The conclusionis that the magnetic field induced by the tower has no effect on the geomagneticobservation.
