摘要
本文提出了用Fokker-Planck方程描述高能重离子碰撞时空演化和系统的驰豫时间。并应用此模型计算了s^(1/2)=31.2 Gev的α粒子束流下及E_L=200 Gev/N的^(18)O粒子束流下末态粒子的快度分布和系统的弛豫时间。
In this paper, the time development of high energy heavy-ion collision and the system relaxation time are described by Fokker-planck Equation. The rapidity distribution of the final state particles and the system relaxation time under s^(1/2)=31.2 Gev α Panicles beams and E_L=200 Gev/N ^(16)O Particles beams are calculated with this model.
