Description We calculate energy distribution of A-star atmospheres (T_eff=10 000 K, log g=4.0) for large interval of abundances of silicon and other lighter chemical elements using adequate model atmospheres. We discuss the reasons and magnitudes of found departures of the stellar energy distribution and uvby magnitudes from the normal state.
