For a model membrane fabricated by impregnating a Millipore filter with dioleyl phosphate (DOPH), a theory is presented to describe two kinds of observed self-oscillations of the electric potential: one is a short-period oscillation with a period of several seconds and the other is a long-period oscillation with a period of several tens of minutes. Both have been observed in the presence of a salt-concentration difference across the membrane. While most of the observed properties have been explained well by former theories, essential deviations between theories and observed data have still been left for the wave forms of self-oscillations in the presence can of an applied electric current. The present theory can describe properties by taking account precisely of the effects of charge accumulation on the DOPH multilayers. The present theory can be used for the analysis of this type of model membrane applied to a chemical sensor.
