摘要：

In the framework of relativistic quantum molecular dynamics we analyse pion chemical potentials in the hadron system produced in central heavy-ion collisions at the bombarding energies E(lab)/A=(1-2)GeV/nucl. We find that the equilibrium relations hold for chemical potentials of pi-, pi0, pi+ and pion energy spectra reach local thermal equilibrium. However, there is no chemical equilibrium. The pion chemical potentials are very large and decrease during the expansion stage.
