本文提出了一种利用光谱资料探讨源函数变化形式的方法;并结合直接搜索法,拟合计算了1984年2月18日太阳边缘环珥的对称谱线,探讨了谱线内源函数随光学深度变化的情况。
A method for exploring the variation in the source function in the line profiles of a loop prominence is proposed in this paper. Some symmetric lines of the loop prominence of 1984 February 18 on the solar limb are fitted by using this method with the simplex method. It is found that only consideration of a simple layer for the symmetrical lines is premitted, even if the source function changes with the optical dept hof the line, and the multiple layer model is less suitable for the analysis of an asymmetrical line profile when the gradient of the line-of-sight velocity is added. Finally, the analysed results are discussed.
