基于蒙特卡罗法（MCM）建立蜂窝结构瞬态传热仿真模型，进行了蜂窝结构隔热性能的数值模拟，重点研究蜂窝腔内不同表面发射率对其传热性能的影响。研究结果表明，在空间低温环境条件下，通过减小蜂窝腔内表面平均发射率可以使蜂窝结构材料具有更好的隔热性能，其中，蜂窝腔内顶面、底面发射率对蜂窝隔热性能的影响大于侧面发射率的影响。

Heat transfer and temperature distribution in honeycomb composites during transient condition were investigated by means of numerical simulations based on Monte Carlo Method. Infrared (IR) radiation in honeycomb core cells was particularly studied and analyzed in this paper in order to find out the effect of emissivity (or size) on heat transfer. The results show that thermal conductivity of honeycomb will be effectively enhanced when emissivity (or thickness) in honeycomb core cells increases. And the effect of top-surface emissivity and under-surface emissivity in honeycomb core cells is more evident than that of side-face emissivity.
