【摘要】 从修正的Fourier热传导定律出发,讨论了激光在一维半无限介质中产生热击波的传播规律。在短时和长时近似下,得到了解析表达式。短时近似解反映非Fourier行为,长时解则退化为经典Fourier热传导定律下的热力耦合波解。更多还原

【Abstract】 Starting from modified Fourier heat conduction law, the propagation law of thermal shock-wave produced by laser light on one dimensional semi-infinite medium is discussed. Analytical expressions are obtained on short time and long time approximations. The short time approximate solution represents non-Fourier behaviour and the long time approximate solution degrades into thermal coupled wave solution in classial heat conduction law.更多还原
