摘　　要： 为弥补二维色度分析的局限性,首先在CIE-L*a*b*色空间及其变换所得L*C*hab坐标系中,对真实表面色色域进行三维色度学分析。为克服二维色度图计算色域覆盖率的片面性,还提出了一种在三维色空间计算色立体体积的近似算法,并与笔者的前期算法进行了比较,表明新算法精度有所提高。 In order to make up the limitation of the two-dimensional colorimetric analysis, at first, the paper makes the three-dimensional colorimetry analysis on the real surface color gamut in the CIE-L＇a＇b＊ color space and the coordinate system of L＊C＊hab which changes from CIE-L＊a＊b＊. For the sack of overcoming one-sidedness of the color gamut coverage in the two dimensional chromaticity diagram calculation. A kind of approximate algorithm is also put tbrwared to compute the color solid volume in the 3D color space, and the author＇s prophase algorithm is compared with, it shows that the accuracy of the new algorithm improves.
