| 摘 要： | 提出了霜层综合导热系数概念。认为霜层导热系数除了应考虑霜层结构复杂性还应计及蒸汽凝华潜热释放的影响。从霜层能量平衡分析出发，导出霜层综合导热系数是霜层有效导热系数和蒸汽有效导热系数之和。据此计算的霜层综合导热系数与实验数据符合较好。

| Abstract: | The concept of general frost thermal conductivity is presented and it is found out that when frost thermal conductivity being concerned, both the complexity of frost structure and the heat of sublimation of vapour frosted should be counted in. Based on the energy equation, the general frost thermal conductivity is drived to be the sum of the effective frost thermal conductivity and the effective vapour thermal conductivity. The calculated thermal conductivities of frost are compared with the experimental data and found to agree well. |
