摘要：

The hadron production in heavy ion collision is treated in the framework of thermodynamic vision. Thermodynamic system formed during central collision of Pb-Pb at high energies is considered, through which binary collision is assumed among the valence quarks. The partition function of the system is calculated; accordingly the free available energy, the entropy and the chemical potential are calculated. The concept of string fragmentation and defragmentation is used to form the newly produced particles. The average multiplicity of the newly produced particles are calculated and compared with the recent experimental results.
