中文摘要：

研究激光相变烧蚀二维结构网格程序，对液-气相变、固液汽三相物质进行整体模拟．激光相变烧蚀二维结构网格程序采用气化相变开始后在迎激光方向局部加密的重分方法，动量守恒方程采用Wilkins三角形回路积分法，能量守恒方程采用基于节点重构的扩散方程有限体积格式．

英文摘要：

We study formation and development of laser-induced heating, melting and evaporating process during laser-m~Ltter interaction. Local adaptive mesh refine method in two-dimensional structured code is adopted as soon as material evaporates along the direction of laser. Wilkins method and finite volume diffusion scheme based on reconstruction of values on vertex are adopted to handle momentum equations and energy equation.
