摘　　要：绘制了 CTAB/正丁醇 -正辛烷 -水和 Al( NO3) 3(或 Na2 WO4 )盐水拟三元体系的 3 5℃相图 .用电导法并结合电解质理论讨论了微乳液的微观结构 ,将整个微乳液单相区分为 W/ O微乳区、O/ W微乳区和 B.C.双连续区 ,并且用渗滤理论确定了一个分散相质点为 W/ O球状结构的反胶团微乳液区 .The phase diagrams of the pseudo-ternary-component of CTAB/n-butanol-n-octane-water or brine[Al(NO_3)_3 or Na_2WO_4] systems were studied by dilution method. The microstructures of microemulsions were determined through conductance technique. Via percolation theory and electrolyte theory the single-phase regions of the microemulsions were delimited as W/O,O/W and bicontinuous microemulsion domains. In the W/O microemulsion regions we got a small domains(L′) in which the dispersed entities are of spherical form. [WT5HZ]
