A classical differences algorithm of simulation of electrode processes was applied for strict modelling of electrochemical oscillations induced by interplay of ohmic drops and negative polarization resistance of the charge-transfer process. The linear and spherical geometry of diffusion was implemented. A numerical way of incorporating constant and potential-dependent double layer capacitances is described. Examples of shapes of oscillations and associated full diffusion profiles of electroactive species are presented. A comparison of this strict modelling of oscillations and typical approximated way of calculations, suggesting the importance of precise calculations, was outlined.
