Abstract：
The HIJING 2.0 is used to generate Monte Carlo events for Au+Au minimum biased collisions at RHIC energies-sNN=130 and 200 GeV. Using the Monte Carlo event sample, it is shown that the impact parameter has approximately a linear dependence on multiplicity. Both of them can be used as characteristic quantity for centrality. The results on the /p ratio show that this ratio does not change remarkably with centrality, transverse momentum and rapidity, and is independent of the reaction plane within the HIJING model.
