磁参数的测定和研究工作，已成为生产和科研人员十分重视的工作。我国已测定了大量的磁性标本，并提出了一些新的磁参数测定和整理方法。但由于地表岩（矿）石露头长期受风化作用和雷电激磁的影响，其磁性很难代表地下深处相应的地质体；特别是地下岩矿石的剩余磁性，由于地层产状的变化，其剩余磁化方向亦随之发生变化，所以用地表采集的磁性标 The determination and research of magnetic parameters have become the work that production and scientific researchers attach great importance to. China has measured a large number of magnetic specimens, and put forward some new magnetic parameters determination and finishing methods. However, due to long-term weathering and lightning excitation of surface rock (mineral) rock outcrops, it is very difficult to represent the corresponding geologic bodies in the depths of the underground; especially the residual magnetism of underground rock ores, the residual Magnetization direction also changes, so the magnetic target collected by the surface
