摘　　要：论文测试了8种白色的无机建筑涂料在黑白卡片纸和透明玻璃板底材上的反射率和对比率,测试结果表明在玻璃板底材上,建筑涂料的黑区反射率偏高,白区反射率偏低,对比率值偏高0.02左右。通过对论文中提出的两种修正方法(对比率修正法和反射率修正法)的研究和比较,认为反射率修正法更符合对比率测试的物理模型,反射率修正法的对比率值与对比率的真实值更接近。This article tested the reflectivity and contrast ratio of eight white inorganic building coatings on black and white card paper and transparent glass plate substrates.The test results showed that on the glass plate substrate,the reflectivity of the black area of the building coatings was higher,while the reflectivity of the white area was lower,with a contrast ratio of about 0.02 higher.Through the study and comparison of the two correction methods proposed in this article(contrast ratio correction method and reflectivity correction method),it is believed that the reflectivity correction method is more in line with the physical model of contrast ratio testing,and the results of the contrast ratio value of the reflectivity correction method are closer to the true values of the contrast ratio.
