摘　　要：考虑到高能核－核碰撞中反应系统的纵向扩展，用热化柱图象对簇射粒子的赝快度分布进行了描述，计算结果与１０°～１０°ＡＧｅＶ能区的实验数据符合。The longitudinal extension of interacting system in high energy nucleusnucleus collisions is considered. The pseudorapidity distributions of shower particles are described by the thermalized cylinder picture. The calculated results are in agreement with the experimental data in the energy ragnge from 10° to 105 AGeV.
