Abstract：
Influence of the central collective flow on two-pardcle correlation function is discussed.The Monte-Carlo calculation is used to describe how the single particle and two-particle spectrum from a hot emission source are effected by the central collective flow.The two-proton correlation function for Ni+Ni system.with b=0fm at 100MeV/u is calculated by using QMD model.The particle interchange model is developed and used to prove the existence of a central collective flow in central sions of 100MeV/u Ni+Ni system.The results show that the two-particle correlation functions are indeed sensitive to the central collective flow.This might provide a method for studying the central collective flow formed in central collisions for medium heavy system at energies above 100MeV/u.
