ABSTRACT . Effective temperatures are determined using a method of criterions of spectral classification and are based on results obtained on the Main Stellar Spectrograph of the 6-m telescope at the Special Astrophysical Observatory with D = 9 A/mm for 27 He-weak and 16 He-rich of determination of Te is no worse than stars. Accuracy

800 for He-weak stars and the results of other au

1800 for He-rich ones. Comparisons of Te with thors say that this method can be used for lous objects. We attempted revealing most

determination of Te of anoma-

characteristic anomalies of the chemical

composition of these stars.
