摘要
本文概述了国内近十年来的光谱分析方法;给出了太阳边缘上双层辐射结构的谱线轮廓公式;提出了具有三层辐射结构的日面及边缘上活动体光谱分析的观点和简略的分析方法,并与本文所述的方法作了比较。作为实例,用三层模型分析了1989年8月17日的Hα环状耀斑谱线。
Analyses of the solar spectra are usually used to study the solar active plenomena. In recent several decades, a lot of analytical methods for a single solar active feature have been proposed. In this paper the author reports on the following pieces of work: (Ⅰ) All the analytical methods of the solar spectral lines given from China in the recent decade are briefly presented, (Ⅱ) The formula for the line profile of the active bodies with the two-layer radiative structur is given, (Ⅲ) The analytical method of the spectra of the active bodies with the three-layer rediative structure is also given, (Ⅳ) The three analytical methods are compared with one another and (Ⅴ) As an example of the three-layer model, two Ha lines of the flare of 1989 August 17, are fitted.
