摘要：
Echelle spectrogrammes of 19 variable Herbig Ae/Be stars were obtained in 1988-1992 in the wavelength interval 4000-7000 Angstrom with the spectral complex ''Zebra'' at the 6-m telescope of Special Astrophysical Observatory, Russian Academy of Sciences (SAG RAS). Kurucz's models were employed for the analysis of the hydrogen absorption line profiles. For all programme and standard stars Ig g gravity parameters were obtained. The location of the stars on the ''lg g-T-eff'' diagram does not agree with the hypothesis that the studied objects are pre-main sequence stars.
