摘　　要：应用色度学原理和方法测量金属矿物的反射色特征,经过许多学者长期的努力,已经取得突破性的进展,目前已受到比较广泛的重视。现在已有一百余种金属矿物测量、计算出表征它们反射色特点的亮度(Rvis)、色调(主波长λ和色度座标X、Y)和纯度(Pe)。In this paper,the problems of the distinguishing characters and the calculative method of Polarization Color Indices of ore minerals are discussed.The new calculative method of Polarization Color Indices of ore minerals according to the Standard System(XYZ)of C.I.E is established.The counting method and processes are described.The luminance,hue and degree of saturation or purity of excitement of Polarization Color of ore minerals can be obtained from above new calculative method with S_(E) as light source.The Polarization Color Indices of more than hundred ore minerals are given.The systematic data,which include the Luminance of Polarization Color Rvis(%),Chromaticity Coordinates x,y,Dominant wave length λ_(d)(nm),and Degree of saturation Pe of Polarization Color Indices,will aid to identify the main anisotropic ore minerals.
