摘　　要：基于高密度、高精度的实际测量数据,建立了中国海区地磁基本场数学模型,研制开发了中国海区磁偏角查询与显示应用系统,从根本上改变了只能从外版图件上手工量取磁偏角获取数据的现状。对保证船舶安全航行和保障装备的安全运行有着重大意义。Based on the precise and reliable geomagnetic data, the China sea geomagnetic field model were established. The China sea magnetic declination query and application system were put into use. It changed the history of calculating the magnetic declination data by hand. It ensured the ship safe navigation and the safe operation of the weapons and equipment.
