月球表面温度物理模型研究现状

-总结了前人对月球表面温度的研究方法，对他们的研究进行了归类，分析了它们各自的优劣。直接测量和基于绕月飞行器的遥感测量均需投入昂贵的发射和维护费用，基于探测数据或月球样品分析数据的研究局限于某些时间段和地点，地基遥感探测的空间分辨率太低，这些方法自身的局限限制它们不可能用于全月的温度变化研究，只有通过建立比较完善的月球表面温度物理模型才可能达到这一目的。重点对月球表面温度物理模型进行讨论，分析了已有的模型，总结了影响月球表面温度的影响因素，包括月球表面太阳辐射、月球内部热流、月球表面物质的热吸收率、发射率、热导率、热容以及密度等，对这些因素的研究现状进行了概括，并提出了进一步研究这些参数的一些想法。

A Review of Lunar-surface Temperature Model

The studied methods of lunar-surface temperature are concluded. They are divided into direct method and indirect method. Their features are analyzed. It is expensive for the launch and maintenance of detector in direct measurement and remote sensing based on spacecraft; the studies based on explored data and analyzed data of lunar samples are limited in time and space; and earth-based remote sensing has a low spatial resolution. Because of these limitations, the above methods couldnot be used in the study of global variation of lunar-surface temperature. To attain such a purpose, the accurate lunar-surface temperature physical model must be made. By analyzing the physical models which have been made, we conclude the factors which influence the lunar-surface temperature, such as lunar-surface solar radiation, lunar interior heat flow, the thermal absorptivity, thermal emissivity, heat capacity, and density of lunar materials. The progress of studies in these factors is depicted. And some proposals are made at last.
