摘　　要：通过测定不同温度时SDS/正丁醇 /二甲苯 /水体系中W /O(油包水 )型、双连续相、O/W(水包油 )型微乳液的电导率 ,计算体系导电活化能。发现该体系活化能随含水量的变化呈“U”型 ,双连续相的电导活化能最低 ,有一极小值。通过对实验结果的分析 ,对O/W型微乳液的导电机理进行了讨论 ,为微乳液的实际应用提供理论基础。The conductance activation energies of SDS/n-butanol/xylene/water system were estimated from electric conductivity data of W/O microemulsion, bicontinucous structure and O/W microemulsion in the system at different temperatures. It was found that variations of activation energy with water content in the system showed the model of U and the activation energy of bicoutinucous structure had a minimum value. The conductance mechanism in O/W microemulsion was discussed, which is a theoretical foundation for the application of microemulsions.
