十二烷基硫酸钠（ＳＤＳ），醇（正丙醇、正丁醇、正戊醇、正己醇）和水三组分体系的相图测定表明两种情况：一种是从ｏ／ｗ型向ｗ／ｏ型转变是连续变化；另一种是从ｏ／ｗ型向ｗ／ｏ型转变是通过层状液晶，即两种结构的胶束是互不相连的．利用电导测量法，证明在第一种类型胶束区域内，从ｏ／ｗ型向ｗ／ｏ型转变的中间连续区域具有双连续结构．相图的胶束区域可分为ｏ／ｗ、ｗ／ｏ和双连续（Ｂ．Ｃ）三个小区域．但是这种双连续结构与微乳液中双连续结构不同，其特性折射常数和自扩散系数测量表明，胶束的双连续结构不遵守微乳液双连续结构的特性折射常数与自扩散系数规律．
Phase diagram determination of sodium dodecyl sulfate (SDS), alcohols (n-propanol, n-butanol, n-pentanol, n-hexanol) and water showed two cases: one from the o / w The change to w / o type is a continuous change; the other is from o / w type to w / o type through the layered liquid crystal, that is, the two types of micelles are not connected to each other. Using conductivity measurement, it was demonstrated that in the first type of micellar region, the mid-continuous region from o / w to w / o transition has a bicontinuous structure. Phase diagram of the micellar region can be divided into o / w, w / o and bicontinuous (B.C) three small areas. However, this bicontinuous structure is different from the bicontinuous structure in microemulsion. The characteristic refraction constants and self-diffusion coefficient measurements show that the bicontinuous structure of the micelles does not obey the intrinsic refractive index and self-diffusion coefficient of the bicontinuous structure.
