前言白度学的理论研究与实践应用在我国近几年发展很快,特别是白度测量有了迅速发展,为此白度测量仪器新产品开发与老产品改造已势在必行,做为白度评价公式中占着主要部分的BGA白度式测量仪器的开发已在我国研制出来,它对于白度测量的应用起到了积极作用,而BGA三色狭波带光度法反射率计的设计与光源是有很大关系的,同时又与三刺激值XYZ是密切相关的,这样BGA与XYZ的相关式同光源与相关系数的确定是很重要的,相关系数q的确定至今还没有详尽的探讨,虽然在不少资料中BG
Preface The theory of whiteness theory and practice of application in our country developed rapidly in recent years, especially the whiteness measurement has been rapid development, so whiteness measuring instrument new product development and transformation of the old product is imperative, as The development of BGA whiteness measuring instrument, which is the main part of whiteness evaluation formula, has been developed in our country. It has played a positive role in the application of whiteness measurement, while the design of BGA tri-color narrowband photometric reflectivity meter And the light source is a great relationship, at the same time with the tristimulus value XYZ is closely related, so BGA and XYZ associated with the light source and the correlation coefficient is very important to determine the correlation coefficient q has not yet exhaustive Discussion, although in a lot of information BG
