Abstract本文对云南天文台1981年5月16日3B级双带大耀斑环(0922 UT)的H_α——SSHG光谱资料作了初步的数据处理。采用外线性函数的最小二乘曲线拟合方法,直接从实测轮廓同时求得了园面耀斑环的线正光学厚渡 τ_o、Dopper宽度Δλ_D、平均能顺当函数(S-bar)_λ及视向速度V_(II),为处理具有时空序列特点的光谱资料提供了一种数值方法。计算结果表明,耀斑环系内的物质由环顶开始沿两环腿向色球层溅落;认为用色球蒸发模型解释环中的物质运动较为合理。
Other AbstractA numerical value method for dealing with the spectra possessing the characteristics of time-space series is suggested in this paper. We process the spectra data of the loops in the declining phase of a two-ribbon flare B taken by Ha-SSHG at Yunnan Observatory on May 16,1981. The optical depth(τ_o) in the center of the line Ha, the Doppler width(Δλ_D), the mean source function((S-bar)λ), and the velocity(V_(II)) in line of sight of flare loops are carried out simultaneously from observated line profile by using the non-linear least-square fitting method. Based on the numerical results, it is found that the material in the flare loops is streamed down to the chromosphere along two legs and believed that this amount of material must be supplied from the chromosphere below through chromospheric evaporation.
