Using cetyl trimethyl ammoniunm bromide as templating agent, the mesoporous TiO_2 with special performance was synthesized by a tartaric acid sol-gel method. The UV irradiation was used in this process.

以十六烷基三甲基溴化胺为模板剂，采用溶胶-凝胶法，在溶胶-凝胶制备过程中引入紫外光照辐射，制备出具有一定特殊性能的中孔TiO2材料。

The structure of these hydrogels is characterized by pH- and electric field-sensitive moieties, azobenzene cross-linking groups cleavable by cecal bacteria and hydrophobic side-chains which may control the swelling properties of hydrogels by adjusting their lengths.

该凝胶的结构特点是：兼备pH、电场双重敏感的特征基团即羧基；含有可被盲肠菌分解的偶氮苯交联基团；带有可控制凝胶溶胀性能的疏水侧基。

According to Q-e equation, EMA and iPMA that are prone to copolymerize with NIPAM were selected to prepare hydrophobically-modified pNIPAM microgels.

根据Q-e方程，通过选择易于与NIPAM共聚的疏水性单体EMA、iPMA，成功制备了疏水性链段在微凝胶网络中无规分布的疏水改性pNIPAM微凝胶。

In the present study,a novel microgel was designed by the incorporation of temperature sensititive N-isopropylacrylamide and pH sensitive acrylic acid to copolymerize with glucosamine derivative,acrylamido-2-deoxy-glucose. The novel microgel has favorable biocompatibility,tissue-targeting and stimuli-responsibility to pH and temperature.

本文利用具有生物相容性的氨基葡萄糖单糖衍生物、具有温敏性的异丙基丙烯酰胺及具有pH敏感性的丙烯酸共聚得到了全新的微凝胶，新型微凝胶具有良好的生物相容性、组织靶向性和对温度、pH的刺激响应性。

The results obtained from Gel Permeation Chromatagraphy showed that, as time dapsed, gel's molecular weight changed increasingly. In other words, gel reaction of sebastan plum cordia was still continnous in 20 days after picking up. Based on AIS percentage analysis of sebastan plum cordia, gelation could be caused from much compounds like polysaccharase and protein.

由GPC分析结果显示，随著时间之增长，分子量的变化由小分子量逐渐凝结成大分子量，因此可知破布子在采收后二十天中其凝胶反应是持续在进行，且由破布子AIS百分比分析结果推测凝胶物质可能是多醣体或蛋白质等分子。

There were crystallizable water and non-crystallizable water in polyacrylate hydrogel; the content of the non-crystallizable water was 2.13 g/g dry resin, much higher than that in non-ionic hydrogels.

聚丙烯酸钠水凝胶中的水有相变水和非冻结水两种存在形式，其中非冻结水含量为2.13g水/g绝干树脂，该数值大大高于非离子型水凝胶。

Encapsulated psoralen were evaluated by dialyzation using psoralen gel as the control. Changes of liposome????encapsulated psoralen and release rate were detected during a 3????week storage at 4 ℃ for evaluating the stability of the liposomal formulation.

以同浓度的补骨脂素凝胶为对照，用透析法检测补骨脂素脂质体凝胶的体外释药模式，并对其在4 ℃下贮存3周的释药稳定性进行研究。

Methods: All the patients recruited were randomized into the diclofenac diethylamine salt gel and diclofenac sodium gel groups and treated with local application three times daily for 14 days respectively.

4 0例患者随机分为双氯芬酸二乙胺盐凝胶组和双氯芬酸钠凝胶组进行临床对照试验，分别采用局部涂擦给药法，tid ，14d为 1疗程。

If whole face is fat, use more relaxed it is easy to if be local only,protect wet gel; give oil, resemble T word place, and two buccal slant dry person, but partition is used relaxed protect wet gel of T word place, the latex that reachs oiliness or lacteal frostlike powder (two buccal or other is dry place) will protect wet.""

若全脸都油，就使用较清爽的保湿凝胶；若只是局部轻易出油，像 T 字部位，而两颊偏干燥的人，可分区使用清爽保湿凝胶，及含油的乳液或乳霜来保湿。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
