摘要：

Hadron multiplicities are calculated in the framework of the algebraic coalescence rehadronization model (ALCOR), which counts for redistribution of quarks into hadrons for relativistic heavy-ion collisions. Dynamical in-medium suppression of the light to heavy quark coalescence factors and the influence of Bjorken flow on the final hadronic composition are incorporated in the model. A comparison is made with the CERN SPS NA35 (S+S) heavy-ion experiment where the total total quark number is fitted to the total charge multiplicity and predictions for NA49 (Pb+Pb) is presented.
