摘　　要：简要介绍了不同太空风化条件下尖晶石的光谱特性,特别是利用Hapke模型计算了不同太空风化条件下尖晶石的二向性反射率分布特征。模拟的结果显示,对M3数据,可比较0.6μm和1.9μm附近的吸收特征;对IIM数据,则需要先分析太空风化程度,然后比较0.6μm和0.9μm附近的吸收特征来判断是否为尖晶石。该结论为选择探月传感器的波段组合识别尖晶石提供了依据,也为应用M3数据和"嫦娥1号"IIM数据的尖晶石判别奠定了基础。This paper briefly introduces the bidirectional reflectance feature of spinel based on space weathering.The distribution of the bidirectional reflectance feature of spinel under the different conditions of space weathering was simulated using the Hapke model.The results show that the absorption features at 0.6μm and 1.9μm could be used to determine spinel when the Moon Mineralogy Mapper(M3)data is applied.However,when the Chang'e-1Interference Imaging Spectrometer(IIM)data is used,the space weathering level should be first analyzed,and then the absorption features at 0.6μm and 0.9μm could be applied to identify the mineral.These results provide the basis of identifying spinel using absorptive positions and depths of the spinel,which can also be applied to M3 data and Chang'e-1IIM data processing.
