摘　　要：通过热化双柱模型研究了相对论性重离子对撞机中运行的(S_(NN))^(1/2)=62.4 GeV不同碰撞中心度Au-Au碰撞中产生的带电粒子的赝快度分布。计算结果与PHOBOS实验合作组测得的实验数据符合的很好,得到了各参数值随中心度变化的函数关系,同时也计算出了两柱的长度值和总长度值。In this article,the charged particle pseudorapidity distribution for Au-Au collisions different impact centrality at Relativistic Heavy Ion Collider energy =62.4 GeV has been study by thermalization double column model.The calculation results meet well with the experimental data of PHOBOS collaboration measured.Function relation of the each parameter values changes along with the centrality have been obtain,as also the length value and total length value of two column have been calculated.
