【摘要】 本文测定了N-月桂酰基-N-甲基牛磺酸钠分别与十二烷基溴化吡啶和十二烷基二甲基丁基溴化铵阳离子表面活性剂混合水溶液的表面张力，计算了分子相互作用参数β[1,2]，利用正规溶液理论对它们的协同效应进行了讨论，计算结果与实验值相符。更多还原

【Abstract】 Systems investigated wrer sodium N-dodecanoyl-N-methyl-taurine (SDMT) ~Bromo-dodecyl pyridine (C12BP) and SOMT~ Dodecyl-dimethyl-butyl-ammonium bromide (G12AB). The surface tensions of the both solution were determined. The molecular interaction parameters β. were calculated for these systems.Using regular solution theory,the synergism was disscussed for them. The calculated results by this theory agreed well with experimental values.更多还原
