摘　　要：在确定非化学计量一氧化钛氧指数范围的基础上,研究了其颜色及其随氧指数的变化规律,并比较了其颜色与现用仿金材料之间的优劣。结果表明,在整个氧指数范围内一氧化钛均呈金黄色;随着氧指数的增大,在可见光作用下,对波长3 5 0～5 5 0nm范围内的紫、蓝和绿光反射逐渐减弱,对波长65 0～780nm范围内的红、橙光反射逐渐增强,其颜色从浅金黄色稍带白青色至纯正金黄色,最后至金黄色偏红;氧指数在1.14～1.16范围内其颜色最接近金黄,TiO1 .1 5与2 4KAu色度差仅为0 .0 0 44 ,较仿金铜、TiN的颜色与2 4K黄金更为接近。Based on determination of the oxygen index value of nonstoichiometric titanium monoxide, its color and variational regularity with its oxygen index were investigated, and the advantages of color between titanium monoxide and conventional imitated gold were compared. The results show that, in the whole oxygen index range, titanium monoxide presents golden color. With the increase of its oxygen index, the reflection intensities of titanium monoxide on violet, blue and green light in the wavelength of 350～550 nm decreased, the reflection intensities on red and orange in the wavelength of 650～780 nm increased, and its color changes from weak golden with slight white and cyan to pure golden, and to golden with slight red. TiO_ 1.14～1.16 has the most similar color with gold, and their color is nearer than imitated copper and TiN. The color difference value between TiO_ 1.15 and 24KAu is only 0.0044.
