月表发射率不仅可用于提取月表硅酸盐和铁镁质矿物等主要造岩矿物成分，作为月表矿物可见光-近红外光谱的有效补充，而且不同尺度上的月表发射率也是地球观测卫星，尤其是大气吸收波段在轨外定标的重要参考源。该研究以月表主要造岩矿物为例，模拟真空环境测量其发射率，分析其发射率特性，并在研究月表热辐射传输方程的基础上，结合月表温度模拟和Apollo样品发射率验证评价，建立适合月球的发射率反演方法，利用月球红外辐射数据反演月表不同尺度的发射率和表面温度。同时，在实验和数值模拟基础上，分析月表发射率的尺度效应，建立基于尺度效应的月表非同温三维结构混合像元发射率尺度转换方法，实现月球卫星和地基红外观测等反演发射率不同尺度的转换，由此反演的月表硅酸盐和铁镁质矿物将在月球岩浆洋形成演化研究上具有重要的科学意义，发射率转换也在地球卫星工程上具有重要的实践价值。

Lunar surface emissivity can be used to extract silicate and femic minerals, which is composed of lunar crust. It is important supplement to luanr mineral visible-near infrared spectra. And different scales of lunar surface emissivities are important calibration sources for infrared channels of Earth satellites. The emissivities of different minerals is measured within vacuum environment and their features will be analyzed. Based on thermal radiation transfer equation, by combining the lunar surface temperature simulation and Apollo samples emissivities, the method will be given for the retrieval of lunar surface emissivity, and the lunar surface emissivity and temperature will separated. In the meanwhile, the scaling effect of lunar surface emissivity will be analyzed by experiments and simulation. And the scaling transformation method for non-isotemperature 3D mixture pixels will be built. Thus the different scale of lunar surface emissivity from luanr satellite and Earth based observatory infrared radiation will be transformed. It will play important scientific significant for lunar magma ocean come-being and revolution by the retrieval of silicate and famic minerals, also the scale transformation of lunar surface emissivity will have important application values for Earth satellite engineering.
