摘　　要：198 4年 5月 5日太阳东边缘土墩日珥的Hα单色像和D3线被观测到了。D3发射线由两部分组成 :主成分和致宽成分。本文利用双层模型方法对该土墩日珥的 1 7条D3发射线成功地进行了计算 ,给出了D3线的计算结果。计算结果表明 :日珥的D3发射线主要由热的多普勒致宽和微观湍流致宽所致 。The mound prominence above the solar east limb on May 5,1984 was observed with Hα monochromatic images and D3 emission lines.17 D3 lines from Kawaguchi et al(1986),which were found to consist of two components,i.e. the main and the broadened components,have been successfully calculated by using the two-cloud model method,and the fitting results are given in this paper.The results obtained show that the D3 lines are mainly broadened by the microturbulence and the thermal movement,and other broadening mechanisms can be neglected.
