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．
Taking into account the longitudinal and transverse excitation of the reaction system in high-energy nuclear collisions, the pseudorapidity distribution and transverse momentum distribution of the shower particles are described by using thermal column images. The calculated results are consistent with the experimental data of the CERNSPS energy region.
