摘要：

Evolution of the hadronic system in heavy-ion collisions is studied with the reaction density. The three-dimensional reaction zones and their projections for different types of hadronic reactions are calculated for AGS and SPS energies within the microscopic transport model UrQMD. On the basis of performed calculations of reaction frequencies, the characteristic points of the time dependence of fireball evolution are obtained. The hypersurfaces which are the reaction zone boundaries are related to kinetic and chemical freeze-outs. The reaction density fireball representation is compared to other possible representations.
