Based on a one-fluid, two-temperature radiation hydrokinetics model, we study the interaction processes of XeCl laser radiation with a one-dimensional aluminium target. The heating processes of the target are described by nonlinear thermal conductive equations. The forming and evolution processes about the densities and the temperatures of laser-generated plasma are govened by the rate equations. According to this model, we give out the numerical code. Our results present the physical pictures of different stages about the plasma evolution. The impulse coupling coefficient agrees fairly well with the experimental results in literature.
