摘　　要：从自相似方法出发,建立了简化的二维X射线激光等离子体流体动力学模型.利用该模型研究了平板靶X射线激光的二维流体力学行为.研究表明,当激光作用结束后,经过一段时间的演化电子密度和温度沿线聚焦方向逐渐达到平衡,该结果对X射线激光的优化设计具有重要意义.A simplified two-dimensional plasma hydrodynamic modal of X-ray laser on slab target is proposed on the basis of selfsimilarity method. The properties of two-dimensional hydrodynamies of X-ray laser plasma are studied using the model. It is shown that after the action of driving laser, the electron temperature and the electron density along the focus line will tend to equibrium with elapse of time. This result has an important meaning in the optimized design of the experiment on the X-ray laser.
