利用蒙特卡罗方法计算了平均参与碰撞核子数，通过傅里叶变换从饱和模型中抽取了未积分胶子分布函数解析式，研究了美国相对论重离子对撞机（Relativistic Heavy Ion Collider, RHIC）能量下金一金碰撞中不同碰撞参数区间的重子阻止现象。计算发现：理论结果能够很好地解释BRHAMS合作组实验现象。在此基础上，对正在运行的欧洲大强子对撞机（Large Hadron Collider, LHC）能量下铅一铅碰撞中大快度区域重子阻止现象作出了理论预言。

The average number of participated nucleons in the collisions is obtained with Monte-Carlo method, the un-integrated gluon distribution function analytic formula is extracted from the saturation models through Fourier transform, the phenomena of baryon stopping at different intervals of collision parameter in Au-Au collisions with Relativistic Heavy Ion Collider(RHIC) energies are studied. Computation shows that the theoretical results are in good agreement with the data from BRAHMS collaboration. Then, the predictive results for the phenomena of baryon stopping in Pb-Pb collisions with Large Hadron Collider(LHC) energies are also given.
