摘要：

The ultrapure water conductance was measured in the presence of lipid or stearic acid monolayers by means of ac and dc four-electrode techniques. Measurements were performed in N2 atmosphere. To maintain pH almost-equal-to 5 phosphoric acid (10(-5) M) or boric acid (0.1 M) was added to the aqueous subphase. In contrast with previous studies, no increase in the conductance was observed on adding a surfactant and compressing a monolayer.
