摘　　要：通过测定不同温度时CTAB/C4H9OH/C7H16/H2O体系中w/o型微乳液的电导率计算了体系的导电活化能。研究了活化能随含水量的变化规律。发现活化能随含水量的变化与微乳液出现渗滤现象有关。讨论了表面活性助剂与表面活性剂的质量比km及起始含油量R对峰值活化能Ea,max的影响。The conduction activation energies(Ea)of w/o microemulsion in CTAB/C4H9OH/C7H16/H2O system were estimated from electric conductivity data of microemulsion at different temperatures.Variations of activation energy with water content(Φw) of microemulsion were determined.It is found that variations of Ea with Φw in w/o microemulsions were closely related to the occurrence of the percolation conduction phenomena.The influence of the cosurfactanttosurfactant mass ratio km and the initial oil content R on the maximum activation energy Ea,max was also discussed.
