【摘要】 用基于测量仪器和样品散射特性的数学模型研究了纸张白度和纸张表面粗糙度的关系,比较了有和没有散射光中的镜面成分条件下的纸张白度和纸张表面粗糙度的关系,纸张白度是根据ISO/D IS 11475计算获得的。结果发现,所研究的纸张白度取决于纸张的表面粗糙度和所选择的照射条件,而纸张的色度坐标与两者无关。更多还原

【Abstract】 The effect of surface roughness and illumination conditions on paper whiteness was studied by numerical model based on measuring apparatus and specimen scattering property.The dependencies computed for various specimen illumination conditions with and without allowing for the specular component of scattered light were compared.The whiteness was calculated by ISO/DIS 11475.It was found that whiteness of the object depends on both surface roughness and the illumination scheme selection;whereas the chromaticity coordinates depend on neither of them.更多还原
