The purpose of the research is to develop a useful solution of interreflection equation in interior with surfaces of non-uniform diffuser(non-diffuse surfaces). and for this purpose directional characteristics of reflection of interior materials are measured and classified into several types.First. directional characteristics of reflection of various interior materials are measured by gonio-photometer using polarized light. Each measured value is divided into the boundary reflected component and the layer reflected one. The results are classified into several types in order to utilize in a solution of interreflection in interior with surfaces of non-uniform diffuser.Second, a general expression of interreflection is introduced in case of surface of uniform diffuserincluding the Fresnel-type specular (regular) reflection component. As an example of a numerical solution of this integral equation the case of ceiling only with such type of surface is dealed with in a side-lit room, and the reflected (indirect) illuminances on the working plane are compared with a case of all surfaces with uniform diffuser.A scale model experiment of a side-lit room is also carried out to supplement numerical solutions. As another question the transmittance of a Venetian-blind system with glossy slats is measured to compare with the numerical solution as a blind system with slats of uniform diffuser.It is concluded that an effect of the Fresnel-type specular reflection is not so clear as far as such surface is partly used in interior. However, if initial luminous flux incidents mainly upon such glossy surface or the initial incident angle of a beam is large on the surface, effects of specular surfaces should not be negleclted in interior.

该研究的目的是开发与非均匀扩散器表面（非扩散表面）的内部反射方程的有用解决方案。为此，对内部材料反射反射的定向特征进行测量并分类为几种类型。使用偏振光通过Gonio-Phototer测量各种内部材料反射的定向特征。每个测得的值分为边界反射的组件，层反射一个。将结果分为几种类型，以便在内部与非均匀扩散器表面反射的溶液中使用。第二，在均匀的分散表面表面表面上引入了互反射的一般表达，从而呈均匀的分散表面，使得浅水平（常规）反射分量。作为该积分方程的数值解决方案的一个示例，仅在侧面灯的房间中处理天花板的情况，并且在工作平面上的反射（间接）照明率与具有均匀扩散器的所有表面的反射（间接）照明。作为另一个问题，测量了威尼斯盲系统的透射率，以与数值溶液作为具有均匀扩散器板条的盲目系统进行比较。得出的结论是，菲雷西型型镜面反射的效果并不那么清楚，因为这种表面在室内被部分使用。但是，如果初始发光通量事件主要是在这种光滑的表面或梁的初始入射角上很大，则在内部不应忽略镜面的效果。
