以激光材料处理为背景，通过在高能脉冲激光照射下材料表面温度变化的实验研究，测量了在这种高能量、短脉冲、温度变化率极大的情况下材料表面的温升速率和温度变化规律，并且结合实验条件对2种不同的导热模型进行了数值模拟．实验结果显示当激光脉冲宽度较大时，实验结果和傅立叶导热模型的计算结果很吻合，随着激光脉冲宽度的减小，实验结果逐渐偏离傅立叶导热模型，而与双曲导热模型比较接近，同时出现了“二次升温”等非常规现象．
In the background of laser material processing, the temperature rise and temperature change of material surface under high energy, short pulse and temperature change rate were measured through the experimental research on the temperature change of material surface under high-energy pulsed laser irradiation. Law, and combined with the experimental conditions of two different models of thermal conductivity were numerically simulated. The experimental results show that when the laser pulse width is large, the experimental results are in good agreement with the Fourier thermal model. As the laser pulse width decreases, the experimental results deviate from the Fourier thermal model and close to the hyperbolic thermal model, There has been “secondary warming” and other unconventional phenomena.
