中文摘要：
用表面张力、电导和法荧光光度法测定了阳离子表面活性剂3-对壬基酚基-2-羟丙基三甲基溴化铵（NPTAX，X=Cl，Br，I）的胶束化行为．根据实验数据及相应的公式确定出临界胶束浓度（cmc）、胶束聚集Gibbs自由能（△Gm），临界胶束浓度时的胶束解离度（a^0）和胶束聚集数．考察了温度、浓度和反离子对这些参数的影响．
英文摘要：
The detailed micellization behavior of cationic surfaetants 3-p-nonylphenoxy-2- hydroxypropyl trimethyl ammonium halide （NPTAX, X = Cl, Br, I） was studied by surface tension, conductivity and steady-state fluorescence measurements in the temperature range of 15 to 50 ℃. The critical micelle concentrations （cmc）, thermodynamics of mieellization （△Gm）, degree of counterion dissociation （a^0） at the eme and aggregation number （Nagg） were determined from experimental data. The effects of temperature and concentrations of surfactant on their various properties in aqueous solution have been investigated, respectively.
