摘　　要：建立激光表面纹理化热模型 ,分析了在纹理化中起关键作用的表面熔化过程 ,计算出表面温度、穿透深度、熔化深度。This work characterizes the laser-induced periodic surface structure of PET fiber by 308 mm excimer laser. The heat model on enthalpy was set up for interaction between the laser and PET. The melt phenomenon was important for surface structure formation. The surface temperature, temporal behavior, melt depth dependence of laser pulse time, temperature spatial distribution in the PET and liquid/solid interface move velocity dependence of time were numerically calculated, and the surface instability was analyzed.
