摘　　要：利用一维辐射流体力学编码数值研究了辐射烧蚀波在平面金靶中的传播情况,并在常温边界条件下得到了辐射流、烧蚀压、质量烧蚀率和特征等离子体密度的定标定律。Thermal radiation can cause larger ablation pressure and mass ablation rate than laser-driven at the same intensity. A code of 1 -D radiation hydrodynamics has been developed and the ablative radiation wave propagating in Au planar targets has been numerically investigated. The scaling laws was obtained for Au planar targets, such as the radiation flow, ablative pressure, mass ablation rate and characteristic plasma density in the case of a constant boundary temperature, are given in this paper.
