摘要：

Microemulsions exhibit a rather sudden change of electric conductivity upon varying either composition at fixed temperature, or temperature at fixed mean composition. In literature this has been interpreted as a percolationlike process. In this paper we question this interpretation, and suggest instead that the change of conductivity is caused by a dispersion inversion that takes place in a plane through the symmetry axes of the three-phase body, irrespective of the volume fraction of the conducting phase.
