查询词典 direct black

As a result, make sure the proportion of black dye is 4.2%, and the formula of the dyestuff C.I. Direct Black 19: C.I. Direct Black 168: Dyestuff I=3:1:1, and when using two surfactants, printing liquidity is better, at same time compare to printing result with national inks, and the result is that confecting inks excels national inks in soaking paper, curliness and edge definition.

最后确定黑色染料所占比例为4.2%，各染料配比为直接黑19：直接黑168：染料I=3：1：1，并且当用两种表面活性剂进行复配时，打印流畅性较佳；同时与国产品牌墨水作打印测试对比，结果自制墨水在有无洇纸和卷曲以及边缘清晰度方面优于国产品牌墨水。

By coupling technology, the removal efficiency of Direct Black 168 can reach 84% within 400 min, while the removal efficiencies are only 73% and 64% using photocatalysis alone or membrane separation alone, respectively.

耦合工艺条件下复合膜6次重复使用实验表明，染料的去除效率可保持在65％以上，且复合膜孔结构稳定，没有明显地损坏，稳定性较好。

By coupling photocatalytic process with membrane separation technology, the removal efficiency of Direct Black 168 (100 mg/L) was improved obviously, being 52% within 400 min, while the values were 20% and 35% with membrane separation alone or photocatalysis alone during the same time, respectively.

以染料直接黑168作为模型污染物(100 mg/L)，实验运行400 min后，通过光催化和膜分离耦合技术，染料的去除达到52％以上，对比单独膜分离(20％)及单独光催化(35％)操作明显提高。

The color fastnesses of treated fabrics dyed with Direct Black GF could compare beauty with sulfur black or reactive black. The reflectivity curve fell greatly compared with untreated, and the darkening effect made it possible to get very full black colour with excellent wet fastness with relative small amount of the dye .

经溶胶-凝胶整理后，直接黑GF的各项色牢度能与硫化黑、反应性黑相媲美，反射率曲线较处理前有较大幅度的降低，增深效果使得用较少的染料染得较浓的黑色成为可能。

The color fastnesses of treated fabrics dyed with Direct Black GF could compare beauty with sulfur black or reactive black. The reflectivity curve fell greatly compared with untreated, and the darkening effect made it possible to get very full black colour with excellent wet fastness with relative small amount of the dye.

经溶胶-凝溶胶一凝胶技术在纺织上的应用与研究摘要胶整理后，直接黑GF的各项色牢度能与硫化黑、反应性黑相媲美，反射率曲线较处理前有较大幅度的降低，增深效果使得用较少的染料染得较浓的黑色成为可育旨。

The dyes were extracted from textiles composed of natural or chemical fibers by methanol under ultrasounication, and then eluted with gradient by acetonitrile and 5 mmol/L ammonium acetate from an RP-C18 column with two segments in effluents. The first effluents accommodated Acid Red 26, Direct Blue 6, Direct Black 38 and Direct Red 28 with negative ionization mode, while the second accommodated Basic Red 9, Basic Violet 14, Disperse Blue 1, Disperse Orange 11 and Disperse Yellow 3 with positive ionization mode. Thus the investigated compounds could be identified simultaneously with single-run analysis no matter which type of the fibre the sample was and no matter which category of the dye the analyte was.

用甲醇超声同时提取天然纤维和化学纤维上的染料，以5 mmol/L乙酸铵和乙腈为流动相在C18柱上于前段洗脱酸性红26、直接蓝6、直接黑38和直接红28（采用电喷雾质谱负离子模式检测），于后段洗脱碱性红9、碱性紫14、分散蓝1、分散橙11和分散黄3（采用电喷雾质谱正离子模式检测），实现了对不同种类纤维织品中分属4类性质不同染料的一次提取和一次分析检测。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
