摘要
中国海域地球磁场模式为舰船消磁而建 ,由国际地磁参考场与网格节点描述的地壳场迭合形成。文中介绍了模式的建立途径 ,地核场、地壳场、消磁用地球磁场的求取 。
The geomagnetic field model in China offshore area is built for ship's demagnetization, which is overlapped by international geomagnetic reference field and the earth's crust field described by the grid node. The way of modeling and obtaining of the centrosphere field, the earth's crust field and the geomagnetic field for demagnetization are introduced in this paper.Methods of building and using of the inquire search system are introduced in the end.
