采用核-核碰撞的Glauber模型, 给出了高能重离子碰撞中的参与者数和核子-核子碰撞数随碰撞参数的分布方程, 并用其讨论了\{sNN\}1/2=200GeV的Au+Au碰撞中的参与者数与核子-核子碰撞数随对心度的变化关系, 所得结果与PHENIX合作组所给出的实验结果符合得很好.

By using the Glauber model of nucleus-nucleus collision, we present the distribution equations for the numbers of participants and nucleon-nucleon collisions versus the impact parameter in high-energy heavy-ion collisions, and analyze with them the centrality dependence of both numbers in \{sNN\}1/2=200GeV Au+Au collisions. The results fit well with those given by PHENIX Collaboration.
