Based on new spectroscopic observational material (high-spectral-resol
ution CCD spectrograms obtained with the coude spectrograph of the 2.6
-m telescope), we analyze the atmospheres of the two SrCrEu stars 17 C
om A and 21 Com in the Coma Cluster by the method of model atmospheres
. The measurements of line equivalent widths are used to estimate the
abundances of eight elements for the atmospheric parameters of these s
tars taken from the Literature by the method of synthetic spectrum. Th
e analysis is based on model atmospheres computed with the ATLAS9 prog
ram and on atomic constants taken from the VALD database. The new resu
lts for the SrCrEu stars lend support to our previous conclusion that
the abundance differences in the atmospheres of chemically peculiar st
ars belonging to the same cluster are real.
