摘　　要：目的评价国际照明委员会(International Commission on Illumination,CIE)1976L*a*b*均匀色空间(CIE1976L*a*b*uniform color space)CIELAB色差公式和CIE DE2000色差公式的视觉相关性。方法选择3篇文献研究Vitapan3D-Master比色板颜色的L*、a*、b*数据,用CIELAB和CIE DE2000色差公式计算各自的色差值△Ea*b和△E00。结果△Ea*b和△E00差异有统计学意义(P<0.01),所有的△E00色差值显著小于对应的△Ea*b色差值,且比△Ea*b色差值更有规律。结论CIE DE2000色差公式的视觉相关性优于CIELAB色差公式。Objective To evaluate visual correlations of CIELAB color difference formula and CIE DE2000 color difference formula by using the parameters of chromatometry from color measurement of Vitapan 3D-Master. Methods △E^＊ab and △E00 were calculated from the values of L ^^ a^＊ and b^＊, which were obtained from three present investiga- tions. Results There were significant differences between △Eab^＊, and △E00. The color difference values of △E00 which was obtained from each group were significantly smaller but more regular than those of △E^＊ab. Conclusion CIE DE2000 has an advantage over CIELAB in visual correlation.
