主磁场建模是一项综合性的研究工作,它涉及主磁场理论、磁场测量、数据同化、模型表达、模型解释以及模型运用等多方面的研究.本文综述了近五十年来德国、丹麦和美英各国研究者提出的数十个地球主磁场模型,回顾了主磁场模型研究方面的进展,概述了模型的描述以及建模的理论基础和方法.
Modeling the main geomagnetic field is a kind of all-around research work, concerning with the research on the main geomagnetic filed theory, magnetic survey, data reduction, model expression, and model interpretation and application. In this article, we present a brief summary of more than ten main geomagnetic field models that have been put forward by many workers in German, Denmark, U. S. A. and Britain over the last five decades. The progresses of the studies on the main field models are briefly reviewed. Finally, the model description, the theoretical basis and construction methods are summarized.
