摘　　要：本文采用积分变换法求解了在激光束辐照下涂层和基体材料中的热传导方程,并在一定的近似条件下,给出了温度场的三维、瞬时分布。以Cr—ZG45钢系统为例,进行了数值分析。The heat conductive equations of coat and substrate materials under laser beam radiations are solved using the method of integral transformation, and the 3D temporal distribution of temperature is given under the some approximations. A numerical analysis is given for Cr-ZG 45 steel as an example .
