中文摘要：

基于多源理想气体模型,用两个方程分别描述了高能重离子中心碰撞中产生的p,K±和π±的横质量分布。在忽略末态粒子的相对论效应的情况下,除π±外,计算结果可近似地描述实验结果。考虑了源的次级样本后,发现计算结果与高能Au-Au和Pb-Pb中心碰撞的实验结果符合得较好。

英文摘要：

Based on the multisource ideal gas model,which do not consider the dynamic mechanism of particles,two formulae are given to describe the transverse mass distributions of protons,kaons and pions produced in central heavy ion collisions at high energies.In the case of neglecting the relativistic effect,our calculated results approximately describe the experimental data,except for pions.By considering the sub-samples of the sources,it is found that our calculated results are in good agreement with the experimental data in the central Au-Au and Pb-Pb collisions at high energies.
