摘　要　顏色感知的基本三要素為物體、光源和人眼,每種要素的變化均會引起顏色感知的變化。但是,在每種要素中,每個波長上同等大小的變化卻顯示出不同程度的顏色感知差異,在某些波長處,呈現(xiàn)較強的靈敏性,而在另外一些波長處有較大的惰性。本文根據(jù)色度學理論,在眾多的勻色空間和色差公式中,以通用性較好的CIE1976L*a*b*勻色空間和色差公式［1］為例,定義了顏色靈敏函數(shù);分別推導出顏色三要素下的物體顏色靈敏函數(shù)、光源顏色靈敏函數(shù)和人眼顏色靈敏函數(shù)的數(shù)學表達式;并在整個顏色空間對三種顏色靈敏函數(shù)進行了比較系統(tǒng)和全面的研究;總結了顏色靈敏函數(shù)的一般規(guī)律。三種顏色靈敏函數(shù)數(shù)學模型在計算機配色、光源的研制、色度儀器人眼的模擬等方面均有一定的應用。 $d\]s]}`

Abstract　According to the chromatic′s theory, color sensitive functions of object, light source and human eyes are defined in the widely used CIE1976L*a*b* color space and color difference［1］. Mathematics formulae are deduced. The three kinds of color sensitive functions are studied systematically and comprehensively in the whole color space. The general law of color sensitive functions are concluded. Mathematics models of the three kinds of color sensitive function can be used in some fields such as computer color matching, making light source and simulation of human eyes of colorimeter. Q[sj/
