| 摘 要： | 偏振反射与二向性反射之间存在着一定的定量关系.通过对不同粗糙程度花岗岩表面偏振反射的测量,计算出它们表面二向性镜面反射分量与二向性漫反射分量的大小,从而定量分析了花岗岩表面粗糙程度对热点与非热点区域两种分量的影响情况.同时通过分析还发现,光线入射天顶角也会对两种分量的大小起到一定的影响,而这种影响的强弱是受到花岗岩表面粗糙程度的控制.

| Abstract: | There is some quantitative relationship between polarized reflection and bidirectional reflection.In this study,the specular reflection and diffuse reflection components were computed by measuring the polarized reflection of granite surfaces that were different in roughness,And then it was quantitatively analysed how the roughness of granite surface influenced the two kinds of components in hotspot and non-hotspot.Meanwhile,through the analysis,it was found that incidence angle would influence the components,and this kind of influence was controled by the roughness of the granite surface. |

| Keywords: | granite polarized reflection bidirectional specular reflection component bidirectional diffuse reflection component roughness |
