| 摘 要： | 通过分析光在介质-空气和介质-表面粗糙基构成界面上和平面分层混浊介质中的反射、散射和吸收规律,提出了混浊介质中传输的光能流将由界面或混浊介质的定向反射和漫反射作用而产生的定向光能流和漫射光能流构成.考虑到这两种光流能量比率的动态转化规律,运用辐射传递理论和四能流光子流传输模式修正了经典二能流Kubelka-Munk模型,建立了四能流Kubelka-Munk模型.研究表明,由经典二能流Kubelka-Munk模型计算得出的色彩要比实际的色彩偏红.

| Abstract: | Based on the analysis of the light reflecting,scattering and absorbing on the air-turbid medium interface,on the turbid medium-rough substrate interface or on the plane-parallel turbid media,we reveal the fact of the total light flux propagating in the layer that contains both the collimated light flux and the diffuse light flux which are caused by the specula reflection and diffuse reflection of the interfaces and the turbid media in the process of color reproduction.Since the phenomenon of the energy of these two parts of the flux are changing constantly,a four-flux kubelka-munk model is proposed in the paper which is a modified two-flux kubelka-munk model for the light propagating in the plane-parallel turbid medium layer and the radiation transfer equation.The investigation shows that the colors calculated by classical two-flux kubelka-munk model are redder than they actually are. |
