摘要：

针对地球磁场起源研究中存在的有关地球磁极问题，在分析地球磁场特征的基础上，从地球磁场的成因和形成磁场的组合形式两方面，对地球磁场进行了分类。研究认为：地球磁场不仅具有突变性和偶极性，而且具有瞬时性、不变性等特征，初步分析了各种特性的影响原因。指出地球磁场具有二分结构，不同的分类方案可得到不同的分类结果，地球磁场可以分为动力磁场和定律磁场，也可以分为绕自转轴的磁场和绕黄极轴的磁场。地球磁场是多种磁场组合叠加形成的复合磁场。这为正确认识地球磁场组成提供了条件。

Abstract:

Aiming at the problem of magnetic axis of the earth in the study of geomagnetic field origin, and based on analyzing geomagnetic field characteristics, the geomagnetic field may be categorized as different types in terms of its origin and its array configuration of formation. This paper proposes that the geomagnetic field not only has mutability and bipolarity but also has instantaneity and invariance, and the influencing factors are analyzed. The paper indicates that the geomagnetic field has a bipartite structure, and that different classified methods have different results, e.g., the geomagnetic field can be classified into dynamic magnetic field and law magnetic field, and it can be also classified into the magnetic field that turns around its own axis and the magnetic field that turns around the ecliptic pole axis. The geomagnetic field is a resultant magnetic field assembled by some individual magnetic fields. This study provides the condition for correctly understanding the constitution of the geomagnetic field.
