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.
