阴离子聚电解质 meaning in Chinese

anionic polyelectrolyte

First of all , nano - alumina dispersed in water is studied . we selected anion polyelectrolyte pmaa and cation surface active reagent ( ctab ) as dispersant . it is discussed that dispersant dosage , ph value , disperse time , disperse means and nano - alumina concentration affect disperse effect
本文首先研究了纳米al2o3在水中的分散，选择阴离子聚电解质聚丙烯酸氨和阳离子表面活性剂作为分散剂，讨论了分散剂用量、 ph值、分散时间、分散方法以及纳米al2o3粒子浓度对分散效果的影响。
The stability of nano - alumina aqueous dispersion is tokened by spectrophotometer and particle size distribution instrument . it is proved that when condition is dispersant pmaa = 0 . 4 % , ph = 9 , nano - - alumina content = 4 % ( wt % ) , ultrasonic for twenty minites , excellent stable nano - alumina aqueous dispersion can be acquired . nano particle average size is 205nm
用分光光度计和粒度分析仪表征了纳米粒子水分散液的稳定性，结果表明纳米相al2o3浓度为4 % ，分散剂为阴离子聚电解质，用量0 . 4 % ， ph = 9 ，采用超声波分散20分钟得到最好的分散效果，纳米颗粒的平均粒径为205nm 。
