摘要：

Data on yields of strange and negative hadrons in full phase space produced in proton-nucleus and central S + S collisions at 200 GeV/nucleon are reviewed. The total number of produced strange and nonstrange valence quark-antiquark pairs is determined on the basis of the hadron multiplicity at freezout. It is shown that the strangeness production factor lambda(s), is increased by a factor of 2 in central S + S collisions, whereas no increase is observed in proton-nucleus collisions.
