摘　　要：基于相对论流体动力学,推导出了黏滞夸克-胶子等离子体的流体动力学演化方程。在大型强子对撞机能标下得到了系统温度随时间和径向半径的分布关系,发现温度对径向半径的依赖十分微弱。数值计算结果表明,横向流效应会加快夸克-胶子等离子的冷却速度,同时降低夸克-胶子等离子体的寿命。The flow evolution equation of quark-gluon plasma is deduced by using the relativistic hydrodynamics.The system temperature distribution at LHC energy with the time and radial distance is also given,and it is found that the temperature is not sensitive to the radial distance.Numerical results show that the transverse flow will lead to the decreasing of the life time and the rapid cooling of the quark-gluon plasma.
