摘要
月球表面热环境的研究对探月活动有重要意义,本文用数值方法分析了月球表面的热环境。首先计算了不同纬度地区地表辐射平衡温度的周期波动,然后建立了月球地表土壤的一维非稳态热传导模型,用此模型计算了不同纬度地区地表温度的波动、月壤温度的波动及恒温层温度和深度,并讨论了月壤热物性对温度波动的影响。结果表明白天的地表温度主要取决于地表的辐射平衡温度,而夜晚的地表温度受到月壤热物性的影响。
The study on thermal environment of lunar surface is very important to the exploration of moon. Thermal environment of lunar surface was analyzed using numerical method in this article. The cyclical fluctuation of radiant balanced temperature was calculated for lunar surface of different latitude. An one-dimensional unsteady heat-transfer model was built for lunar regolith. The temperature fluctuation of different lunar surface and regolith, as well as temperature and deepth of homothermal layer were calculated using this model numerically. The influence of thermophysical properties of lunar regolith on its temperature was analyzed and discussed. The results indicate that temperature of surface in daytime is mainly depended on its radiant ballaned temperature, while temperature at night is affected by thermophysical properties of regolith.
