摘　　要：本文根据阳离子导电机理,圆满地解释了P507(K)-醇(正丙醇—正已醇)-正庚烷-水四组分组成的W/O型微乳液的活化能-含水量曲线。并发现含水量较少、温度低于30℃时,表面活性剂阴离子与K^+组成的离子对,充当导电载体。The curves between the activation energy AE v. s. water content VH2o of the microemul-sions composed of P507(K)-alcohol (propanol,butanol,pentanol and hexanol)-heptane-wa-ter were studied. According to the electrical conductivity mechanism, with cation as the charge carrier,three types of figures composed of P507(K)-hexanol(pentanol) ,P507(K)-bu-tanol and P507(K)-propanol were explained successfully.
