摘要
本文基于傅里叶定律之上提出了双相系统模型描述两相混合材料中的瞬态热传导过程，分析表明两相混合材料中的瞬态导热过程不能再用单相一维傅甲叶导热定律描述，这一点已为砂粒堆积床的实验所证实，而且双相系统模型与实验结果相符合。
Based on Fourier's law,this paper presents a two phase system model to depict thetransient heat conduction in mixed two-phase materials. It is shown that one dimensionalFourier's model fails to describe the fast transient conduction in mixed two-phase materials, which is confirmed by experiments. The two phase system model correlates well withexperimental data of sand.
