摘　　要：通过双光束光谱光度计的测定（３８０～７２０ｎｍ），研究我国精制浅色松香产品的颜色特性。由光谱透射比数据，计算对于Ｃ光源、２°现场ＣＩＥ色度系统的色品坐标ｘ、ｙ值和总透过率Ｙ（％）值。找到影响颜色特性的因素，从而选定划分等级的标准透射叫线及色品坐标、总透率。研究确定最稳定的比色方法，并初步探讨使用国产有色光学玻璃来配制符合分级标准的标准物质。Colour characteristics of refined light coloured rosin products were studied by using a dual beam spectrophotometer (380～720 nm).Chromaticity coordinates,x,y,for CIE uminant c,visual angle 2°and Luminous Transmittance Y(percent)can be calculated from the spectral transmittance data. Factors affecting colour characteristics were investigated and standard curve of transmission,chromaticity coordinates and Lu-minous Transmittance for grading were accordingly decided and selected. Colorimetric method giving most stable results was worked out,and compound colour standards for grading purpose using China made coloured glasses as raw materials were also prepared experimentally
