英文摘要	Based on the model setting is carried out to describe the interaction between static electric field and cell and the calculation of the transmembrane potential, and the Nernst formula and the Boltzmann formula, the method which to analyze the influence of the static field on the quantity across ellipsoid-cell membrane is investigated by using the theorem of electromagnetic induction. Furthermore, numerical studies were used to detect and verify the transition of ion exchange across the membrane. Some interesting results are approached as follows. The exchange of ions across the membrane and fluctuation of membrane potential are dependent on the position, orientation of electric field applied on the membrane of cell and the cell-shape. With the increasing of the field angle (between the direction of applied field and the direction of ellipsoid semi-major axis) and the semi-axis ratio ρ, it is found that the maximal ratio of ion concentration on the side of the ellipsoid-cell will reduce when external field is applied on the cell membrane, and its positions θ max will increase. Under a certain cell superficial area or volume, θ max is increased as ρ goes up. The larger field intensity for the electrostatic field with the noise, the smaller signal to noise ratio, as a result, the rate of relative change of the ion concentration will increase. The mechanism for transition in transmembrane ions could be that media or cell can be polarized when appropriate electric field is applied on ellipsoid cell even noise is considered. © 2018, Science Press.
