标题： Exploring the Origin and Dynamics of Solar Magnetic Fields

摘要： 太阳是一颗磁活动强烈的恒星，是太阳风、电磁辐射和高能粒子的来源，这些物质影响着日球层和地球的大气层。 太阳的磁场负责太阳大部分动态活动。 本论文研究旨在理解太阳磁场的生成以及磁场在太阳大气动力学中的作用。 具体而言，本论文聚焦于两个主题：在第一部分中，我们利用磁流体动力学发电机理论和建模来研究太阳磁场的起源和行为；在第二部分中，利用观测和数据分析，我们研究太阳物理中的两个主要问题，即日冕加热问题和太阳耀斑的触发机制。 显示英文摘要

摘要： The Sun is a magnetically active star and is the source of the solar wind, electromagnetic radiation and energetic particles which affect the heliosphere and the Earths atmosphere. The magnetic field of the Sun is responsible for most of the dynamic activity of the Sun. This thesis research seeks to understand solar magnetic field generation and the role that magnetic fields play in the dynamics of the solar atmosphere. Specifically, this thesis focuses on two themes: in the first part, we study the origin and behaviour of solar magnetic fields using magnetohydrodynamic dynamo theory and modelling, and in the second part, utilizing observations and data analysis we study two major problems in solar physics, namely, the coronal heating problem and initiation mechanisms of solar flares.
