氧化铝及其水合物的反射比与色差

The reflection ratio and chromatic aberration of Al_2O_3 and it's hydrate

本文以日立307型色彩分析仪,ILL10°D65、ILL2℃光源,在波长380～775nm范围内,对氧化铝及其水合物的反射比进行了研究;又采用CIE1976(Lab)空间和CIE1976(Luv)空间研究了氧化铝及其水合物的色差。物料的色调多为正值,反射比随波长变化的总增值为2—4％。

The reflection ratio of Al2O3 and it's hydrate has been studied by Hatachi 307 hue analyser. The wavelength range was 380 - 775 nm,The light was ILL 10° D65 and ILL2° source. And,their chromatic aberration has been studied in space of CIE 1976(Lab )and CIE 1976 (L u v). The tone of material is almost positive,and,the incremental quantity of reflection ratio is 2-4% with changing wauelength.
