水性

If you are using urethan enhanced printing, coating after 8 h of natural drying, you can use water-based ink business card printing and membership card.

如果用氨基甲酸乙酯强化印版，涂布后经过8h的自然干燥，即可使用水性油墨制卡和会员卡制作。

Because you want to use water-based ink, paint, or urethan, phenol-formaldehyde resin on the printing plate for water resistance.

因要使用水性油墨，所以要用漆或氨基甲酸乙酯、酚醛树脂对印版进行耐水强化处理。

Urethan resin for better stability, but business card printing and membership card making suitable to their needs and less soluble Li anzhai and other styryl modified monomaleate resin, water-based Amino resins, and polyvingl acid and carboxymethly celluiose, and so on, these polymer resin generally with the-COOH,-OH,-NH

氨基甲酸乙酯树脂的稳定性较好，但制卡和会员卡制作适性和可溶性要略差一些，其它还有用苯乙烯改性马来酸树脂、水性氨基树脂以及聚乙烯酸和羧甲基纤维素等，这些高分子树脂一般均含有-COOH、－OH、－NH

The 4 nucleotides of DNA sequences can be further encoded with two - bit digits in which t he first bit is the base bit to encode purines and pyrimidines and the second bit is the functional group bit to encode the keto group and amino group. According to the degree of degeneracy of genetic codes and the two dimension distribution of molecular weights and isoelectricpoints of amino acids , a set of classification graph(Venn' s diagram) of amino acids can be obtained. It is suggested that the amino acids of high degenerate group are mostly small and simple, and constitute the transmembranic structure or the structural domains of protein molecules. So amino acids of high degenerate group might appear in the early evolution stage.

根据氨基酸遗传密码子的简并程度并以分子量及等电点作为氨基酸的化学特性坐标，作出其二维集合MP分类图，根据氨基酸的分类分析，可以认为：高简并度氨基酸多数是脂烃类和羟脂烃类的氨基酸，分子量比较小，分子结构比较简单，大部分为疏水性，主要组成跨膜结构或蛋白质的结构域，可能是出现较早的氨基酸；而低简并度的氨基酸，分子结构比较复杂，分子量比较大，多数是和蛋白质功能有密切联系的基团，可能是进化出现较晚的结构。

The specific properties of materials, such as the palate adhesion, dynamic cruor, anti-bacterial and the degradability of lysozyme, were studied, which provide valuable data for further application. The main creative ideas are listed as follows:(1) The water-retention chitosan/poly vinyl alcohol blend fiber was obtained by coagulating in 10％ NaOH/ethanol solution, and the blend and crosslink due to GA can enhance the mechanical properties of fiber;(2) The controlled degradable chitosan/gelatin blend fiber was obtained by solution filature, and the mechanical properties were improved;(3) The N-acylchitosan with the different degree of substitution were successfully prepared, and the relationship between structure and properties was estabilished;(4) By a new solvent system of 6％ NaOH/4％ urea for cellulose, the blood anti-coagulant function films were prepared by blending cellulose with chitin;(5) In the same solvent system above mentioned, the anti-bacterial blend films based on cellulose and carboxymethyl-chitosan were prepared, and the relationship of DS and the anti-bacterial property was concluded;(6) The controlled degradable chitosan films was obtained by the chemical crosslink.

本论文的主要创新点：（1）以NaOH水溶液／无水乙醇为凝固液，采用溶液纺丝法制备出保水性壳聚糖／聚乙烯醇纤维，共混和戊二醛交联极大提高了壳聚糖纤维力学性能；（2）用壳聚糖和明胶共混，以溶液纺丝法制备出可控降解的壳聚糖／明胶纤维，并大幅度提高了壳聚糖共混纤维的干、湿态抗张强度；（3）确立了不同取代度N-酰基壳聚糖的合成方法及其膜的结构与性能的关系；（4）利用纤维素新溶剂6％NaOH／4％尿素制备出抗凝血性纤维素／甲壳素共混膜；（5）利用上述纤维素新溶剂制备出抗菌性纤维素／羧甲基壳聚糖共混膜，揭示了羧甲基壳聚糖取代度与抗菌性能的关系；（6）制备出可控降解壳聚糖交联膜。
