摘　　要：为解决罗维朋颜色体系量值溯源问题,提出了用光谱光度法研究罗维朋颜色体系。实验数据分析表明:在单波长下,罗维朋滤色片的光谱密度和罗维朋数之间有明显的线性关系;在380~780 nm波长范围内,罗维朋滤色片的积分光密度和罗维朋数之间也有明显的线性关系。通过美国油品化学协会所提供的数据验证了关系式的可靠性。In order to solve the metrological traceability of Lovibond color system,a spectro-photometric method is proposed to study the Lovibond color system.The analysis of experimental data shows that there is an obvious linear relationship between the spectral density and the Lovibond number at single wavelength,in the wavelength range of 380~780 nm,the relationship between the integral optical density and the number of Lovibond is also obvious.The reliability of the relationship is verified by the data provided by the American Oil Chemists Society.
