本文发展了二维狭义相对论流体动力学方程在笛卡尔网格上的真多维HLL黎曼解算子和有限体积格式，并研究了其物理约束保持（PCP）性质。几个数值结果表明的准确性，性能和分辨率的冲击波和真正的多维波结构的建议PCP计划。
英文摘要：
This paper develops the genuinely multidimensional HLL Riemann solver and finite volume scheme for the two-dimensional special relativistic hydrodynamic equations on Cartesian meshes and studies its physical-constraint-preserving (PCP) property. Several numerical results demonstrate the accuracy, the performance and the resolution of the shock waves and the genuinely multi-dimensional wave structures of the proposed PCP scheme.
