发展了一种研究相对论重离子碰撞的光滑粒子流体动力学(SPH)方法。为了描述高能低重子数密度流体的流动，采用了熵作为SPH基。该方法利用变分原理，得到了任意曲线坐标系下的SPH方程。几个例子表明，SPH是研究相对论重离子过程中强子流的一种很有前途的工具。
A smoothed particle hydrodynamics (SPH) method is developed for the study of relativistic heavy-ion collisions. In order to describe the flow of a high-energy but low baryon number density fluid, entropy is taken as the SPH base. The method is formulated in terms of a variational principle, and the SPH equations for an arbitrary curvilinear coordinate system are obtained. Several examples show that SPH is a promising tool for the study of hadronic flow in relativistic heavy-ion processes.
