 动态散射 [dòng tài sǎn shè添加此单词到默认生词本
dynamic scattering

  1. 并通过纳米粒度仪、动态散射、静态光散射、透射电镜等手段对聚合物微凝胶粒子的结构形态和性质进行表征。
    The structure morphology and properties of the microgel were characterized by use of nano particle sizer, dynamic and static light scatering and TEH.
  2. 为了探索和验证聚合物分子尺寸与岩石孔喉尺寸的配伍关系,以河南油田东部老油区稀油油田为例,应用数学方法、微孔滤膜过滤方法和动态散射方法,对开展聚合物驱条件下拟使用的聚合物的分子尺寸进行试验测定,得到了双河油田不同渗透率岩石能够匹配的聚合物分子量。
    In order to probe and prove the compatible relations between the molecular size of polymer and pore throat size of rocks,an experimental detection is conducted on the molecular size of polymers to be used under the condition of polymer flooding with mathematical method,pore film filtration method and dynamic scattering method by using thin oilfield in Henan Oilfield for example.The molecular weight which can be compatible for the rocks with different permeabilities is obtained.
  3. 采用紫外光谱、相图、动态激光光散射、同位素示踪、光学显微镜、电导率等研究了羧甲基纤维素系列高分子表面活性剂与甲苯-水-异丙醇体系微乳液的形成过程,发现微乳液粒子大小均一,形态一致,其尺寸比低分子表面活性剂所形成的微乳液粒子大得多.醇分子插入到油水界面,改变了两相界面结构,促使微乳液的生成.电导率测定表明所形成的微乳液区均为水包油结构,即使在富含甲苯区域,亦不会有油包水的反相胶束形成.
    Polymeric surfactants were prepared by ultrasonic copolymerization of carboxy methyl cellulose (CMC) and alkyl poly(etheroxy) acrylate.The polymeric microemulsion was prepared by mixing polymeric surfactants aqueous solution,toluene and alcohol at given ratios.The results of dynamic laser scattering indicated that the microemulsion droplets have almost same size and conformation,and the size of polymeric microemulsion particles,which is much bigger than that of low molecular weight surfactants,is beyond the limit of microemulsion definition.But the systems are still thermodynamically stable.The results of isotope tracer analysis indicated that more and more alcohol molecules insert to the interface of oil and water,changes the interfacial structure of phases and finally help microemulsion formed.The whole structure of microemulsion is oil core surrounded by water.The formation of reverse micelles is shown to be unlikely even in toluene-rich region.
