本文提出用Fokker-Planck方程描述高能重离子碰撞时空演化,并用它分析在200AGeV的~(16)O束流和~(32)S束流下,末态粒子的快度分布,并确定了不同系统的弛豫时间,得到了可以和通用经验数值相比较的结果。

In this paper, the time evolution of high energy heavy ion collisions is described by Fokker-Planck Equation. The rapidity distribution of the final state particles is analysed with this model for ~(16)O and ~(32)S particles beams of 200 AGeV. The relaxation time for various systems are determined.
