| 摘 要： | 给出了正入射条件下铝漫反射板在紫外－真空紫外波段的漫反射特性及硫酸钡和聚四氟乙烯（PTFE）漫反射板在紫外波段的漫反射特性；以中国计量院提供的已知正入射半球反射比ρ（0,d）的聚四氟乙烯漫反射为参考样品，通过比较测量得到了铝和硫酸漫反射板的ρ（0，d）以及硫酸钡漫反射板的ρ（0,d)在半年内的衰减情况。计算了三种漫反射板的双向反射分布函数fBRDF（0，θd）。

| Abstract: | Characteristics of a ground aluminium diffuse plate atultraviolate-vacuum ultraviolate(UV-VUV)and that of a BaSO4 and a polytetrafluoroethylene (PTFE) diffuse plate at UV are described. The ρ(0,d) of the BaSO4 and the ground aluminium diffuse plate in 250 nm～400 nm is measured by comparing with the PTFE diffuse plate whose ρ(0,d) is known. Also,the aging of the ρ(0,d) of the BaSO4 diffuse plate is presented. The fBRDF(0,θd) of the three diffuse materials is calculated. |
