Examples

  1. The study of silk fabric grafted with hema
    甲基丙烯酸羟乙酯接枝改性真丝织物的研究
  2. Oxygen transmissibility and permeability of nvp - hema hydrogel materials
    角膜接触镜材料的透氧性能
  3. N - vinylpymolidone - co - 2 - hydroxyethyl methacrylate ( nw - co - hema ) copolymer had been widely studied and used as soft contact lens and controlled - releasing materials in foreign countrys . but this hydrogel material ' s oxygen penetration capability was closely correlated to its equation water content . when the hydrogel had high equation water content , its oxygen penetration capability was improved , but its mechanism performance was droped
    N -乙烯基吡咯烷酮( nvp )和甲基丙烯酸-羟己酯( hema )的共聚物水凝胶作为软质接触透镜材料(隐形眼镜)和药物释控材料,在国外已经得到深入研究和应用,但是这种水凝胶材料的氧气透过性能与其平衡含水量密切相关,水凝胶含水量较高,其氧气透过性能有所提高,但材料的机械性能下降。
  4. The results of the uni - factor experiments and perpendicular experiments show their best mechanic synthesizing craft as followed : nvp ( 10 % wt ) , kh570 ( 20 % wt ) , hema ( 70 % wt ) , initiator ( 0 . 2 % wt ) , crosslinker ( 20 % wt ) , reacting 20 hours under 80 c . the factors which influenced organic silicon modified pvp hydrogel soft contact lens material ' s swelling capabilities were researched , which included temperature , monomer content , ion concentration etc . the experiments showed the equation swelling content ewc improved with the increase of nw , droped with the increase of kh570 and ion concentration , improved then droped with the raise of temperature , and hydrogels got the least ewc at 45 c . experiment carried on todiscuss water dehydration mechanism of organic silicon modified pvp hydrogel soft contact lens materials , which showed dehydration process could be divided into evaporating stage and diffusing stage
    正交实验结果表明, nvp ? hema ? kh570共聚物的机械性能最佳时,其合成工艺条件为: nvp用量10 (质量百分含量,下同) , kh570用量20 , hema用量70 ,引发剂aibn用量0 . 2 ,交联剂nmba用量0 . 2 ,反应温度为80 ,反应时间16h 。讨论了单体配比、溶胀温度、离子浓度等因素对有机硅改性pvp水凝胶软接触透镜材料溶胀性能的影响。实验得出:水凝胶材料的平衡溶胀度ewc随单体nvp含量的增加而增大, ewc随kh570用量的增加而减小,随离子浓度的增大而略微降低,随溶胀温度的升高先稍微下降后有所提高, 45时平衡含水量最低。
