Abstract: Two new arithmetic formulas Of semiderivation for convolution voltammetry were presented based on the semiderivative property.With the derived formulas, the current function of linear sweep voltammetry was discussed in non-dimensional level,and the results are in complete accord with the G1 equation's under the same given parameters.In addition,the proposed arithmetic would afford direct and clear theoretical evidence for studying the link between linear sweep voltammetry and staircase voltammetry.
