摘　　要：本文主要研究尖晶石族矿物在 50～650℃,2～40μm波长范围内的红外光谱发射率和总发射率。文中共研究了三十余种尖晶石族矿物的发射率。测试结果表明,尖晶石族矿物的发射率的大小受其成分、晶体结构、温度和波长的制约。过渡族中的着色离子将大大增加矿物在红外短波段的发射率。This paper is mainly concerned with the total emittance and spectral emittance of spinel miner-als at 50-650℃ and at 2-40μm wavelength. The spectral emittances of more than thirty spinelminerals have been studied. The results of physical measurements show that the spectral emittanceis dependent on the structure, composition, temperature and wavelength. The presence ofcolorable ion would greatly enhance the emittance of spinel-group minerals in the infrared shortwavelength range.
