The results indicate that there is the significant linear correlation between the decoloration value and half-time and molecular descriptors, especially MW/S and number of azonic groups of azo dyes. Moreover, a QSPR model of azo dyes was achieved and used for calculation of predicted decoloration value and half-time of the dyes.

结果表明，染料分子结构描述符MW/S值、芳香环数目偶氮基数目和与I/O值与脱色率和半衰期之间存在着较好的线性相关性，其中MW/S值和偶氮基数目对脱色率和半衰期的贡献最为显著；所获得的QSPR定量关系模型可用于计算和估计水溶性阴离子偶氮染料的理论脱色率和半衰期。

For example, benzidine and β-naphthalene amine, actually though its importance for the syntheses of dyes, especially azo dyes, have been banned for the sake of their strong carcinogenic activities to cause professional bladder cancer.

例如，联苯胺和β-萘胺曾经是非常重要的染料中间体，它们能导致职业性膀胱癌而被禁用，因此非诱变性芳胺的研究，特别是联苯胺和β-萘胺的代用研究，已经引起染料学科的广泛关注。

Some novel NLO copolyethers containing azo dyes as chromophoric side chains have been synthesized by a nuclophilic reaction of azo dyes with polyepichlorohydrin .

这类聚合物有的具有明显的液晶特性，设计合成具有推-拉电子结构的偶氮苯侧基可以表现出二阶NLO性质。

Flavonoid natural dyes are an important class of natural colorants, but they have some drawbacks such as lower substantivity to fiber and relatively small molar extinction coefficient; pyrazolone azo dyes have been widely applied for a long time, however, their fixation on fiber is still not perfect.

黄酮类天然染料是极其重要的一类天然色素，但存在对纤维亲和力差，摩尔消光系数低等诸多缺点：吡唑啉酮类偶氮染料尽管被长期广泛应用，但在纤维上的固色率仍不理想。

Two different fading procedures were studied. One is the oxidation procedure on polyester fibers,the other is the reduction procedure on wool fibers.The study of oxidation procedure mainly focused on 11 disperse azo dyes and 11 disperse anthraquinone dyes. The study of reduction procedure mainly focused on 7 pyrazolone coupled acid azo dyes and 10 azo disperse dyes which has sulfonic group on the couple component.

本论文研究了11支偶氮型分散染料，11支蒽醌型分散染料在聚酯纤维上的分子结构与光牢度的定量关系，同时研究了7支以吡唑啉酮为偶合组份的偶氮型酸性染料和10支偶合组份上带有磺酸基的偶氮型酸性染料在羊毛纤维上的分子结构与光牢度的定量关系。

The relationships between the structures and properties of dyes were studied via DTA, light permanency and solvent resistance test which indicated that anthraquinone dyes were better than azo dyes in heat resistance and light permanency and the azo dyes in which the coupling components were pyridone were better than the other azo dyes.

通过DTA、耐晒及耐溶剂浸取等实验手段研究了染料的结构与性能之间的关系。实验结果表明，蒽醌类染料的耐热性能、耐晒性能优于偶氮类染料；以吡啶酮为偶合组分的偶氮染料的性能优于其他系列的偶氮类染料。

From the investigation into the visible spectra and performances on textile of these azo dyes, as acid dye, it was found that these dyes had deep coloring effects on dyeing wool or silk, and five of which could dye wool into black one at 3% o. w. f., especially the diazo dye derived from 2, 8-diamino-10-methoxy-5, 10-dihydrophenophosphazine 10-oxide and acet-J-acid, it could not only dye wool into black one but each fastness of the obtained dyed sample was good.

对这些已知结构的染料进行浸染染色，结果发现，它们作为酸性染料，在羊毛及丝绸纤维上染色时，能够获得比一般偶氮染料不宜获得的深色效应，其中5支染料得到黑色染样，尤其由2，8-二氨基-10-甲氧基-5，10-二氢磷杂吖嗪与乙酰J-酸形成的双偶氮染料得到黑色染样，其各项牢度都比较理想。
