摘要
考虑到高能核核检撞中反应系统的纵向扩展与横向激发，用热化柱图像对簇射粒子的赝快度分布和横动量分布进行了描述，计算结果与ＣＥＲＮＳＰＳ能区的实验数据符合．
The longitudinal extension and transverse excitation of interacting system in high-energy nucleus-nucleus collisions are considered.The pseudorapldity and transverse momentum distributions of shower particles are described by the thermalized cylinder pic-ture. The calculated results are in agreement with the experimental data in CERN SPS ener-gy region.
