By using Reimann-Stielties series expansion method, two new current equations of linear sweep voltammetry and staircase voltammetry are obtained, which natrually bring the two basic voltammetry togather. Analyzing their current function in non-dimentionl ev el, the results show: their "resemblance" was constrained not only by the sampling fraction α, but also by the stair number N. When α=0. 303, the influence of N becomes very small,and when N→∞, the effect of α is negligible. Especially t in the case of N→∞, α= 1. 0, the current function of staircase voltammetry is thoroughly idential to that of linear sweep voltammetry.
