根据连续激光加热靶材的实际情况，建立了连续激光辐照材料的三维物理模型。结合实际的边界条件，采用基于积分变换的方法推导出材料的瞬态温度场的解析表达式。利用Matlab软件数值模拟了连续激光辐照材料的温升过程，分析了材料的各向异性对温度场的影响，并且讨论了激光参数、辐照时间以及环境变化对靶材温升的影响。结果表明：材料的各向异性将导致温度场的非对称温升；材料表面温升随激光功率和辐照时间的增大而增大；同时材料侧面与空气的对流换热系数对材料表面的温度场分布也起到了一定的影响。

Based on the actual situation of continuous wave (CW) laser heating target material, the three-dimensional physical model of material irradiated by CW-laser is established. Combining with the actual boundary conditions, the analytical expression of the transient temperature field of the material is deduced based on the integral transform method. The temperature rising process of material irradiated by CW-laser is simulated numerically using Matlab software, the influences of the anisotropy of the material is analysed, and the influences of the laser parameters, irradiation time and the environmental changes on the temperature rise of the material are discussed. The results show that the anisotropy of the material will lead to an asymmetric temperature rise, the temperature rise increases with the increase of laser power and irradiating time, and the convective heat transfer coefficient between the material sides and the air plays an important role in the temperature distribution of the material.
