| 摘 要： | 按照夸克随机组合的简单组合模型,本文通过分析得出重子反重子比率与夸克反夸克平均产生几率的关系．进一步计算了相对论重离子碰撞过程中各种反粒子与粒子的比率,不需要任何额外假定, 预言的比率与RHIC加速器时Au Au碰撞STAR实验的结果基本一致．表明夸克组合模型能够解释相对论重离子碰撞过程的反粒子与粒子比率．

| Abstract: | In virtue of the simple physical picture of quark combination model, we determine the dependence of anti-particle to particle ratios on the mean production probability of anti-quarks and quarks. The ratios of various anti-particle to particle at relativistic heavy ion collisions are calculated without any additional assumption, which are consistent with the experiment results of the Au Au collision at (?) measured by STAR collaboration at RHIC. These results provide a basis for further studies 9f particles ratios in relativistic heavy ion collisions. |
