中文摘要：

基于三火球模型,用蒙特卡罗方法计算了40和158AGeV能量下Pb-Pb碰撞中产生的Λ,Λ-和Ξ-强子的横质量分布。在计算中发现射弹核火球、中心火球和靶核火球在横向有明显的扩展,并且模型计算的结果与NA49合作组的实验结果相一致。

英文摘要：

Transverse mass distributions of Λ,,and produced in Pb-Pb reactions at 40 and 158 AGeV are described by an expansive three-fireball model.A transverse expansion is observed in our calculation.The calculated results,by the expansive three-fireball model,are in agreement with the experimental data of NA49 Collaboration.
