摘要We present the analysis of Her spectra obtained during a two-ribbon flare observed on the solar disk on May 16, 1981 at Yunnan Observatory with the Spectra-Spectroheliograph (SSHG). The complicated asymmetric profiles produced by the post-flare loops overlying flare ribbons are analysed with a fast method based on the cloud model method. This method takes into account the bright background of the loops and allows computation of the physical quantities of loops crossed by the slit: velocity field, optical thickness, source function and Doppler width. Using the scanning spectra of the region, we obtain 2-D maps of these parameters. The validity of the method used is compared with other methods and the sensitivity of parameters to solution is discussed in details. The results obtained with this method are compared with those given by Heinzel et al. (1992) using a fully non-LTE approach.
