| 摘 要： | 本文通过对层状结构材料表面受到周期热流作用时的一维及三维稳态热传导问题运用拉氏变换、Hankel变换、传输线理论和反积分变换进行理论解析,得到被加热点的温度响应,并将其与周期加热热流进行比较,得出两者位相差、振幅比对于复合结构的依存性,由此定义对比度,从而确定结构测量原理,为表面下热结构测量信号的反演提供理论依据和方法.

| Abstract: | This work solved 3D steady heat conduction problem in multilayered thin film structures with periodic laser heating,using Laplace transform,Hankel transform,transmission line theory and inverse transformation;Comparing the temperature response with the periodic heating flux,the phase lag and amplitude ratio depending on the composite structure have been obtained.The measurement principle of thermal characteristic,and prepared for the deduction of thermal parameters are provided. |
