Surfactants are ubiquitous in natural water . adsorption of surfactants with particles suspended modifies the surface characteristics of solid particles which are very important to coagulation 表面活性剂广泛存在于天然水体中,水中悬浮颗粒表面由于吸附表面活性剂而改变表面性质,从而对水处理中混凝工艺产生影响。
The paper attempts to break through the superficiality and blindness of the research on current pattern of websites profit , and try to explore the choice of websites " dynamical profit mode from a strategic perspective 本文试图突破目前对网站盈利模式研究的表面性、盲目性,从战略高度来探索网站动态盈利模式的选择。
Owing to its many advantages , it has become a powerful technique in polymer field such as the characterization of the surface morphology and properties , the visualization of phase separation , and the investigation of polymer on nanometer scale 近年来，其应用已由对聚合物表面几何形貌的观测发展到纳米级结构和表面性能的研究领域。
( 2 ) the morphology and electrical properties of meh - ppv films were studied by atomic force microscopy , x - ray photoelectron spectroscopy . it is found that technics of fabrication affect the devices ’ performance ( 2 )利用原子力显微镜、紫外分光光度计对meh - ppv薄膜表面性能以及电性能进行了研究,讨论了薄膜制备工艺对器件性能的影响。
The results showed that it is possible for seed of hydrophobic white carbon to realize encapsulation of white carbon with polymer , and in this reaction system , the concentration of surfactant , should be close to its cmc 本文还采用在位分散聚合方法制备了甲基丙烯酸甲酯二氧化硅微米级复合材料，讨论了不同表面性质的白炭黑对其性能的影响。
( 1 ) the surface properties of mixed solution of 4 - bapta and ctab were investigated . the tem and dls showed that 4 - bapta and ctab have combined to form stably vesicles , and the mechanism of vesicle " forming was also discussed ( 1 )研究了ctab bapta混合体系的表面性质， tem和dls表明混合体系中产生了稳定的囊泡，并对囊泡的形成机理进行了讨论。
Neither distinguishable as human nor inanimate objects , the autonomous images that exist solely as superficial appearances problematize the relationship between the representation and the inner reality when discussing the origin of beauty 这些图像，既不可辩为人，亦不可辨为无生命的物，仅靠表面性自成一律的这些图像，质问了诉说“美”的表象与内在的关系。
