介绍了二维三温辐射磁流体动力学程序MARED的物理模型，给出了该程序对土星和强光一号装置在不同电流和负载参数下的一维模拟结果，得到了等离子体参数的时空分布，结果表明，MARED程序适用于不同脉冲功率装置和负载条件下的模拟，通过对不同负载材料的模拟结果进行比较，结果表明，在相同的负载质量下，钨丝阵列内爆的X射线功率大于铝丝阵列内爆的X射线功率; MARED模拟还表明，计算的X射线功率随负载电流的增大而增大，随负载质量的增大而减小。
The physical model of a two-dimensional three-temperature radiation magneto-hydrodynamics code,named MARED,is introduced.The code's 1 D simulation results are also presented,which include results for different currents and load parameters on facilities of Saturn and Qiangguang-Ⅰ.The plasma parameters' spatio-temporal distributions are obtained,and their self-consistent dynamic variations suggest that MARED code applies to simulations on different pulse power facilities and load conditions.By comparing results with different load materials,it is found that X-ray power of tungsten wire-array implosion is greater than that of aluminium wire-array for the same load mass.In addition,MARED simulations also show that the calculated X-ray power goes up with the load current,and goes down if the load mass is increasing.
