摘　　要：地物在发射电磁辐射的过程中,会表现出与其自身性质相关的偏振特性。岩石作为构成地球岩石圈的主要物质,其热辐射也存在偏振特性,并且这一偏振特性会受到诸多因素的影响。为了定量分析单一因子及其交互作用对岩石热辐射偏振度的影响,作了三因素三水平的正交实验设计,利用热红外辐射计对岩石样品的热红外偏振度进行测量,运用SPSS软件对实验数据进行处理。结果表明,岩石类别以及探测方位角均对岩石的热辐射偏振度产生极其显著的影响,而其交互作用对岩石的偏振度产生显著影响;探测天顶角对岩石的偏振度产生一定影响,而探测天顶角与其他因素的交互作用均对岩石的偏振度没有影响,该结论为岩石的热红外偏振遥感的定量研究提供了重要依据。In the process of the emission of electromagnetic radiation, the surface features will show the polarization properties in relation to its nature. As the main material constituting the earth lithosphere ,the rock＇s thermal radiation also has its own polarization property,which is subject to many factors. To make a quantitative analysis of the influence of a single factor and the interaction of factors on the thermal radiation degree of polarization of the rock, it has made a threefactor and threelevel orthogonal experimental design, using the thermal infrared radiometer to measure the thermal infrared degree of polarization of the rock samples, and using SPSS software for the experimental data process ing. The results show that both the rock category and the detecting azimuth have a extremely significant impact on the thermal infrared degree of polarization of the rocks, and the interaction effects between the two have a significant im pact on the thermal infrared degree of polarization of rocks. The detection zenith angle has some impact on the degree of polarization of rocks, but the interaction effects between the detection zenith angle and the rock category and the de tecting azimuth do not affect the degree of polarization of rocks. The conclusions will provide an important basis for the further quantitative study of the thermal infrared polarization properties of rocks.
