摘要：

We perform water self-diffusion measurements in ternary DDAB microemulsions near the structural transition point. This allows experimental investigation of the predicted anomalous diffusion behavior exhibited near a static percolation transition. Near the transition point time-dependent behavior is observed. The scaling behavior is consistent with theory for a static percolative medium. This is the first time anomalous diffusion has been experimentally measured in a well-characterized porous media.
