Recent investigations of stellar chemical composition made it possible to estimate some parameters of the galactic disc chemical evolution: the abundance gradient, d[Fe/H]/dR, and rate of enrichment, d[Fe/H]/dt. Practically all the conclusions of these investigations were based on data on chemical composition of single stars, for which the error in age determination is considerable.
