DDO color system

The DDO method is used to determine platinum and palladium simultaneously in High-grade nickel matte.

采用了铅试金法富集与分离、DDO法测定高冰镍试样中铂和钯。

By the color patches of medium lightness and chroma of Munsell color system,experiments were made with 34 pairs for lightness and 25 pairs for chroma altering of 5R,5Y,5G,and 5B separately,and then got a serial of new weight functions.

为了对CIEDE2000色差公式计算中等色差时的权重函数SL,SC进行修正,使计算结果与人眼的视觉感觉相一致,选用了孟塞尔(Munsell)颜色系统中的中等明度和中等彩度色块,在5R、5Y、5G、5B 4个主色调的颜色区域分别改变明度和彩度进行计算,改变彩度时共有34对样品,改变明度时共有25对样品,得到新的修正系数。

Applying the principle of linear transformation between color systems,correcting measure values relatively to measure reference,the mutual comparison between measure values is improved.

对在不同的测量仪器上测量同一颜色样品，测量结果不同的问题，利用颜色系统之间的线性变换原理及相对测量基准对测量结果进行修正，以提高测量结果之间的相互比对性。
