摘　　要：采用一维单流体双温度辐射流体力学模型，在激光产生的等离子体做等温膨胀的假定下，研究了脉冲强激光辐照固态靶材时，计及再辐射后汽化等离子体特征参量与靶材物质和激光参数之间的定标关系，计算了等离子体再辐射对激光靶材耦合效应的影响。By means of a hydrodynamic model in which electrons and ions have different temperature and same isothermal expanding velocity,it deals with interaction process of the intense pulse laser with the target,and gives scaling relationships between the plasma parameters and the laser or the target behaviour,in which include equilibrium absorption and radiation in the plasma.
