| 4. | Manufacturer of fine chemicals including tribromoneopentyl alcohol , dibromoneopentyl glycol , and tris - 2 - hydroxyethyl isocyanurate -主要生产乙二醛及芦丁。包括公司及产品介绍。 |
| 5. | We tested the hypothesis that hydroxyethyl starch ( hes ) is superior to lactated ringer ' s solution in pigs for preserving tissue perfusion during acute normovolaemic haemodilution 我们通过试验来探究hes对于猪急性等容性血液稀释过程中保留组织的灌注是否优于乳酸林格液。 |
| 6. | Polymer dispersed liquid crystal ( pdlc ) films are prepared from photo - polymerization of ( cholesteryl acrylate / 2 - hydroxyethyl methacrylate / liquid crystal ) mixtures induced by ultraviolet radiation 摘要选用丙烯酸胆固醇酯甲基丙烯酸-羟乙酯液晶复合体系,在紫外光照射下制备聚合物分散液晶薄膜。 |
| 7. | We randomly assigned 383 children with moderately severe shock to receive ringer ' s lactate , 6 percent dextran 70 ( a colloid ) , or 6 percent hydroxyethyl starch ( a colloid ) and 129 children with severe shock to receive one of the colloids 我们随机分配383例中重度休克儿童接受乳酸钠林格注射液、 6 %右旋糖酐70 (一种胶体液)或6 %羟乙基淀粉(一种胶体液) , 129例重度休克儿童接受两种胶体液中的一种。 |
| 8. | Activated membranes for covalent immobilization of hydroxyethyl cellulose ( hec ) and chitosan were obtained by the reaction of microfilitration nylon membrane with activation reagents such as bisxirane , 1 , 1 ' - carbonyldiimidazole , epibromohydrin and formaldehyde 以尼龙膜为基膜,分别将亲水性物质羟乙基纤维素和壳聚糖共价键合在膜上,制得尼龙羟乙基纤维素复合膜和尼龙壳聚糖复合膜。 |
| 9. | 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。 |
| 10. | The operation principle and device to produce acetin and hydroxyethyl acetate for foundry firming agent were analyzed in the paper , and the choice of esterification catalyst and dehydrated agent in the esterifying process also were analyzed theoretically , and finally , the better producing operation device , catalyst and dehydrated agent were obtained 摘要分析了铸造用有机酯固化剂酯酸甘油酯和乙二醇醋酸酯合成工艺原理及装置,同时对有机酯合成工艺条件中脱水剂和催化剂的选择的理论依据进行了分析,得出铸造用有机酯固化剂的最佳合成工艺装置和脱水剂、催化剂。 |
