摘　　要：根据 1 984年 5月 5日土墩日珥D3线的拟合结果 ,本文分析了该土墩日珥的物理特性。结果发现 ,形成活动边缘的物质呈间歇性抛射 ,抛射物质的密度、温度在观测前期有显著变化 ,湍流速度异常之大 ,达 30km/s。土墩日珥的物理特性较一般 ,其D3线可用微观湍流 3～ 8km/s和低温 50 0 0～ 80 0 0K解释。Based on the fitting results of the D3 emission lines of the mound prominence above the solar east limb on May 5,1984,physical properties of the active edge and the mound prominence are reduced.It is found that the active edge in front of the mound prominence is formed by the intermittent ejections of the matter with different density and different temperature at different time during the early period of the observations,and the microturbulent velocity is unusually large,about 30 km/s.The physical property of the mound prominence is normal and common,and its Doppler width of the D3 lines can generally be interpreted with low temperature of 5000～8000K and a turbulent velocity of 3 to 8 km/s.
