IGRF在地磁研究中的应用

The application of International Geomagnetic Reference Field to the basic researches

IGRF(国际地磁参考场)资料在地磁学的基础研究中得到广泛的应用.利用IGRF国内外学者研究了高斯分析、地球磁场模型及其源场可能位置、重磁关系、核幔耦合、地磁场能量、地球非偶极子磁场以及长期变化场的西向漂移等,研究了IGRF在我国地区的误差以及产生的原因.在研制中国地磁等值图中也得到某些应用.

The data of IGRF (International Geomagnetic Reference Field) are widely used in the geomagnetic basic investigations. By using the IGRF data, the geomagnetic researchers have investigated the Gauss Analysis, the model of the geomagnetic field, the possible position of its sources, the correlations between the geomagnetic and the gravitational fields, the core-mantle electromagnetic coupling, the energy of the geomagnetic field, and the westward drifting of the geomagnetic non-dipole field and the secular variation field. Also investigate the IGRF errors in the china continent and their reasons. Some IGRF data are used in drawing up the China GRF.
