The potential differences between glass electrode and calomel electrode, Vna and Vh, and the electric conductivity σ were measured at rest and at stirring in the aqueous solutions of sodium dodecyl sulfate(SDS) over the concentration range 10(-4)~10(-1)mole/l at 25℃ by the improved system of apparatus, by which Vna and Vh could be measured with the accurady ±0.05mV in the normal electrolyte solution, even in the humid season. The unusual increments of Vna, Vh by stirring are found in the SDS solutions above 7~8×10(-4) mole/l. It is verified by a few experiments, that these increments of Vna, Vh by stirring result from the structure change of the SDS membrane which formed on the liquid junction part of calomel electrode.
