摘　　要：介绍了夸克组合模型的原理和夸克组合律(QCR)的基本步骤。解释了相对论重离子碰撞RHIC和夸克胶子等离子体QGP的产生,详细描述了夸克组合模型在相对论重离子碰撞中的应用。本文使用了蒙特卡罗方法通过程序实现组合机制下对RHIC反应的模拟,并在拟合实验的基础上重点分析了组合机制下夸克横动量分布对强子横动量分布的影响。本文绘制出重子介子比的动量谱并得出一些有意义的结论 。We introduced the theory of QCM and the basic steps of QCR, explained what is RHIC, and the formation of QGP. Furthermore, we expanded on the application of QCM in RHIC, brought about imitating RHIC under composition mechanism by using Monte Carlo method, and analyzed the effects from the momentum distribution of quarks to the momentum distribution of hadrons under the composition mechanism. Finally, the momentum spectrum of specific value of baryon and meson was drawn and some meaningful conclusions were reached.
