在无探针条件下，用电化学方法测定了SDS／BA／H2O三组分体系的扩散系数和扩散活化能．结果表明，L1区域由O／W结构做乳液与油、水观连续结构徽乳液（BI）两个小区域组成，并不是单一的O／W区域.在O／W区域内，微乳液以液滴状态存在，具有较好的扩散性能和较小的扩散活化能；在BI区域，水与BA同作为连续相与被增溶相存在，统合体系呈网络结构，扩散性能较低，扩散活化能较大．
In the absence of probe, the diffusion coefficient and diffusion activation energy of SDS / BA / H2O three-component system were determined by electrochemical method. The results showed that the L1 region was composed of two small regions of O / W structure emulsion and oil and water continuous structure Emulsion (BI), not a single O / W region.In the O / W region, In the BI region, water and BA are the same as continuous phase and solubilized phase, and the integrated system has a network structure with low diffusion ability and diffusive activation energy Larger.
