摘要
研究了金属/窗口界面在冲击压缩下的热弛豫过程。从热阻模型出发,给出了弛豫时间常数与界面热阻以及材料热输运系数之间的函数关系。讨论了本文模型与Grover和Urtiew模型之间的关系。对两种不同的实验记录图象进行了解释,对产生界面热阻的原因进行了初步分析。
The thermal relaxation processes at metal/window interfaces under shock compression are studied. Starting from the contact resistance model,a functional relation between the thermal relaxation time and the interface thermal resistance as well as the thermal transport coefficients of materials is obtained. The present model is compar ed with Grover and Urtiew' s model. Two noncoincidence experimental results can be explained by the present model,and the reasons for the contact resistance are analyzed tentatively.
