Flexo business card printing and membership card-making is a kind of a relief business card printing and membership card, the original mapamodelheaderfactory wetof amine business card printing and membership card making, originated in the United States in the early twenties, as a result of the use of aniline dye ink toxic instead development, since then, the getting started with ink factory is a known and acceptable color agent, in the United States in 1952, the 14th Annual Symposium on packaging is more name flexo business card printing and membership card, in Taiwan has also been translated into Boo Suh relief business card printing and membership card.

柔性版制卡和会员卡制作是一种凸版制卡和会员卡制作方式，最初被称之为笨胺制卡和会员卡制作，起源于二十年代初期的美国，因其使用的苯胺染料油墨有毒，而没有得到发展，此后，油墨制造厂开始使用大家公认且可以接受的色料药剂，于1952年在美国第十四届包装研讨会上被更为名柔性版制卡和会员卡制作，在台湾也被翻译为富瑞凸版制卡和会员卡制作。

胼胝质的染剂是苯胺蓝，间苯二酚蓝和玫红酸。

The varying tendencies of partition coefficients of some compounds in aqueous or nonaqueous solvent systems by calculating the phase equilibria with universal quasichemical functional group activity coefficient model are predicted. These compounds included saturated and unsaturated fatty acids ethyl esters,N2,4dinitrophenylamino alcohols, pnitrophenyl glucosides and so on, with simple structures and much differences in polarity.

以饱和及不饱和脂肪酸乙酯、2，4二硝基苯胺基脂肪醇和对硝基苯基葡萄糖甙等结构较为简单、极性差别较大的溶质系列为研究对象，应用修正的通用基团活度系数模型，通过相平衡计算，预测了它们在含水或不含水的溶剂体系中分配系数的变化趋势，并与前人的工作进行了对比。

Aniline compounds containing heptafluoroisopropyl was synthesized through taking sodium dithionite as evocating agent, and introducing heptafluoroisopropyl by free radical electrophilic substitution on benzene ring.

以连二亚硫酸钠为引发剂，在苯环上通过自由基亲电取代反应引入七氟异丙基，合成了一系列含七氟异丙基的苯胺类衍生物，研究了各种条件对反应的速度和收率的影响。

It is demonstrated that living polymerization can be achieved when the concentration of electron pair donors such as DMAB or Et3N is higher than that of trace water in the polymerization system,and that polymers with narrow molecular weight distribution can be obtained.

发现当N，N-二甲基苯胺或三乙胺的浓度稍高于质子性杂质的浓度时，即能实现异丁烯的活性聚合，得到分子量分布较窄的聚合物。
