利用走时变换反演一类集总特性的热学参数

Inversion of a Kind of Thermal Parameter with General Character by Using Delay-time Transform

采用走时变换将多参数分布热传导模型转化为集总特性参数热传导模型,进而利用脉冲谱反演算法重构集总特性热学参数沿深度方向的分布.数值结果证明了采用该变换的可行性及有效性.利用走时变换研究此类集总特性的热学参数对进一步了解材料热学性质有一定的实际意义.

Delay-time transform is applied to convert multi-parameter thermal model into general-parameter thermal model. Then Pulse-Spectrum Technique inverse algorithm is used to reconstruct the depth profile of the thermal parameter with general character. The numerical results demonstrate the feasibility and effectiveness of the proposed method.
