摘要：

The evolution of the hot central region produced in central heavy ion collisions is analyzed. It is shown that the main properties of the final state can be understood as a result of an adiabatic expansion process. The role of the entropy per particle as a global characteristic of the system is emphasized. Our main concern is the evolution of the chemical composition.
