Firstly, the homopolymerization of acrylamide was carried out in aqueous phase by reversible addition-fragmentation chain transfer radical polymerization using a trithiocarbonate as a chain transfer agent.

整个过程分为两步，首先在水溶液中，通过RAFT控制得到亲水性单体丙烯酰胺的均聚物；然后以得到的均聚物作为水溶性的大分子链转移剂，在水相中条件下参与亲油性单体苯乙烯无皂乳液聚合。

The sizes of the self-assembly micelles of the amphiphilic block copolymers and the effects werestudied by dynamic light scattering and UV-visible spectrophotometer. The micelle sizes werelargely influenced bythe hydrophobic chain content in the copolymer, the properties of the solvent and the copolymer concentration in the organic phase. The morphology of the micelles was investigated by transmission electron microscopy. Theresults showed that the micelles appeared spheres with inner core and outer shell. The critical association concentrations were determined by pyrene monomer fluorescence probe technology. The degradability of copolymer was studied by the loss of the intrinsic viscosity in the degradation process. The results indicated that the degradation rate of PECL was slower thanthat of PELLA and PEDLLA. The stability of the copolymer micelle dispersion was examined by measuring the critical flocculation concentration, which gradually decreased with increasing the content of thehydrophobic chain in the copolymer. The rheological results showed thatthe viscosity ofthe micelle dispersion with higher content of PEG segments was firstly decreased and then increased with the increasingthe temperature. Otherwise, the variation of viscosity was irregular. The viscosity of the micelle dispersion increased with the increase of the electrolyte (Na 2SO 4) concentrations. Polymer micelles paclitaxel was prepared by self-emulsification/solvent evaporation method and solid dispersion technique with amphiphilic block polymers as the carrier material.

运用动态光散射和紫外分光光度计研究了两亲性嵌段共聚物自组装胶束的粒径及其影响因素，结果表明，自组装胶束的形成机理受制备方式的控制，胶束的粒径随着共聚物相对分子质量或疏水嵌段相对分子质量和有机相中共聚物浓度的增大而增大，随着有机溶剂的水溶性的增强而减小；采用透射电镜观察胶束的形态结构，发现胶束呈具有核壳结构的均匀球形；采用芘荧光探针法测两亲性嵌段共聚物的临界聚集浓度；通过降解过程中共聚物特性粘度的变化研究两亲性共聚物的降解性能，发现与PELLA和PEDLLA的相比，PECL 降解速率较慢；随着共聚物中疏水嵌段含量的增大，纳米分散液的稳定性逐渐下降；PEG含量高的PEDLLA纳米分散液随着温度的升高，纳米分散液的粘度先下降然后增大，反之，没有规律性，且随着电解质Na 2SO 4浓度的增大，体系粘度增大。

For the high affinity sites, binding constant decreases with the decrease of the alkyl chain lengh in the surfactants, but for the low affinity sites, binding constant increases and are not distinct when the alkyl chain is dedocyl. The binding sites are related to the alkyl chain lengh, not for the number of hydrophile groups and temperature.Isothermal titration calorimetry has been used to observe the enzyme-catalyzed hydrolysis reaction of urea.

对于高结合位点，结合常数随疏水碳链长度的减小而减小；对于低结合位点，结合常数随疏水碳链长度的减小而增大，相应的当碳链减小至C12时，低结合位点不明显，结合位点数可能只与碳链长度有关，随亲水头基和温度变化不明显。

He said: I heard that the Yantai iris water plot house price rose, also did not know that is what reason, there before also does not have the real estate evaluator, now heard that gave manages down, north the area, south the area chefoo area iris water plot should have the scale, was the plot wide band how own, the iron passed the net to pass has?

烟台分类妈妈消息，今天一网民来电咨询关于烟台芝水小区在哪的相关问题，他说：我听说烟台芝水小区房价又涨了，也不知道是什么原因，就那里以前也没有房产证，现在听说又给办下来了，北区、南区芝罘区芝水小区应该有规模吧，小区宽带怎么亲，铁通网通都有吗？

In the phase-boundary reactions of cyclohexene hydration and isoamyl acetate hydrolysis, these amphiphilic zeolite particles are oriented at the aqueous-organic phase boundary and exhibit catalytic activity obviously superior to the parent zeolites.
