太阳发电机理论研究进展

Progress in Solar Dynamo Theories

太阳发电机理论主要解释太阳磁场的起源和演化,是太阳物理中最基本、最重要的问题之一。对它的研究不仅具有重要的科学价值,而且对空间天气的预测和空间技术的发展有一定的影响。随着日震学的发展,该理论也得到了很大改进。从相关观测入手,综述了发电机理论需解释的观测事实,以及为发电机理论提供约束的太阳内部动力学结构;介绍了基本理论和近来的主流模型,并指出尚待解决的问题和进一步的努力方向。

The solar dynamo, which explains the origin and the evolution of all magnetic fields observed on the sun, is the fundamental and essential question of Solar Physics. Scientific inquiry into the question is more than an academic exercise. It is important to the development of space technology and the prediction of terrestrial climate. With the development of helioseismology, the solar dynamo has made great progresses. Staring from the observation, the paper summarizes some observations on the solar surface and the dynamic construction interior. The basic theories and the central models are introduced. Some unsolved problems are discussed.
