【摘要】

：

以过氧化氢-抗坏血酸(H2O2-H2A)为引发剂,采用溶液自由基接枝聚合法将N-异丙基丙烯酰胺接枝到棉纤维上,制得接枝棉(CF-g-PNIPAAm).讨论了引发剂浓度对接枝棉的接枝率和温敏性的影响.结果表明:随着引发剂浓度的增加,接枝率先升高后降低,随后趋于平缓;H2O2为0.06mol/L,H2A为0.036mol/L,单体为0.6mol/L时获得最高接枝率(21.1wt％)的接枝棉;接枝棉的低

阿哈水库浮游植物功能群时空分布特征及其影响因子分析

为了解贵州高原阿哈水库的浮游植物功能类群时空分布特征及其影响因素,于2012年至2013年枯水期、平水期、丰水期对浮游植物与水样进行分层采样分析.结果表明:浮游植物可分为23个功能群,优势功能群为B、D、J、LO、P、S1和X1,其时空分布特征表现为:枯水期、平水期与丰水期分别以B+D+P+LO、S1+LO以及S1为主,其丰度由枯水期至丰水期依次递增;优势功能群主要在15m以下水体发生变化,营养物
