守恒型格式在计算多介质问题的扩展euler方程组时在物质交界面附近会产生强烈的震荡，同样的困难存在于lagrange坐标系下一般的守恒型格式对多介质问题的计算中。 - Numerical simulation is a very important aspect for this research , in which the main task is to solve the system of radiation hydrodynamic equations , especially , we usually do this task using lagrangian coordinates , and in this case the numerical treatment of three - temperature energy equations is a main difficulty
数值模拟是这项研究的非常重要的手段，其核心内容是求解辐射流体力学方程组，而其中三温能量方程的数值处理又是在lagrange坐标下求解辐射流体力学方程组的主要难点之一。 - This paper applies kami ' s method to analyze conservative scheme in lagrangian coordinate , and then selects one of upwind schemes which do not show oscillations , finally applies it to construct high resolution scheme . numerical flux of one order scheme is used near interface , while numerical flux of high resolution scheme is adopted in other area
本文在对lagrange坐标系下的守恒型格式进行详细分析后，甄选出不震荡的一阶迎风型格式，然后应用于lagrange坐标系下的高分辨率格式，在物质交界面处采用不震荡的一阶迎风型格式的数值通量，而在其余地方采用高分辨率格式的数值通量。
