采用不同溶剂（四氯化碳、正戊烷、正庚烷和正癸烷）构建的油包水微乳液的低频电导率，在5到60°C的温度范围内，在水与表面活性剂比W为2到20的不同值下进行了测量。基于Eicke、Hall和Halle最近提出的电荷波动理论和影响对结果进行了分析。已经评估了由于两个相邻水滴之间的表面活性剂尾部相互渗透引起的短程吸引相互作用。
The low-frequency electrical conductivity of water-in-oil micro-emulsions, built up with different solvents (carbon tetrachloride, n-pentane, n-heptane and n-decane), has been measured in the temperature interval from 5 to 60°C, for different values of the water-to-surfactant ratio W, from 2 to 20. The results have been analyzed on the basis of the charge fluctuation theories recently proposed by Eicke, Hall and Halle and the effects of short-range attractive interactions due to surfactant tail interpenetration between two adjacent water droplets have been evaluated.
