测定了十二烷基磺酸钠(AS)/十六烷基三甲基溴化铵(CTAB)/正丁醇(n-C4H9OH)/正庚烷(n-C7H16)/水(H2O),十二烷基硫酸钠(SDS)/十六烷基三甲基溴化铵(CTAB)/正丁醇(n-C4H9OH)/正庚烷(n-C7H16)/水(H2O)体系的微乳液正四面体相图，并用电导法划分了AS/CTAB/n-C4H9OH/n-C7H16/H2O体系微乳液的结构(W/O,B.C.和O/W)；同时研究AS/CTAB/n-C4H9OH/n-C7H16/H2O/盐类(NaCl,CaCl2或AlCl3)体系和SDS/CTAB/n-C4H9OH/n-C7H16/H2O/盐类(NaCl,CaCl2或AlCl3)体系形成中相微乳的盐宽，从中得出上述两体系中相微乳的盐宽随盐类阳离子价态的增大而的规律。

Microemulsions composed of AS/CTAB/n-C4H9OH/n- C7H16/H2O and SDS/CTAB/n-C4H9OH/n-C7H16/H2O were studied. Through measuring we investigated the structure of such microemulsion as W/O, B.C. and O/W. In present of brine, middle-phase microemulsion can form. The influence of salinity on formation and characteristics of the middle- phase microemulsion is discussed.
