coloured order

The color difference under different superimposition sequence was measured and analyzed.

分析了不同的叠印色序情况下叠印色样之间的色差,实验结果表明,叠印色样的偏色偏向后印油墨颜色,叠印色序对印品的颜色质量有较大的影响,为印刷的生产实践提供了可靠依据。

On basis of the numbered rule of IUPAC and the structure characteristics of unsaturated chain hydrocarbon,a colouring number(t_i)is given,and on the basis of adjacency matrix,an new autocorrelation topological index(~mR)and its complementart inex ~mR′ are constructed from t_i.

依据系统命名法的编号原则及不饱和链烃的结构特证,建立了原子的染色序数(ti),并在邻矩阵基础上由ti构建原子染色序数自相关指数(mR)及互补指数mR′,其中0R1、R、互补指数0R′1、R′,C原子个数(N)与炔烃的沸点、烯烃的热力学性质(标准生成焓、标准熵、标准熵和标准生成自由能)有良好的相关性,相关系数分别为0。
