摘　　要：对受前行化学反应控制的络合吸附催化体系叠式循环阶梯脉冲伏安法进行了理论研究和实验验证，讨论了电流的特性．发现无论是正向扫描或逆向扫描、是正脉冲还是负脉冲，电流都是同方向，叠式循环电流相当于将单向脉冲电流叠加４次。The Additive cyclic staircase pulse voltammetry for complex adsorption catalytic system controlled by the preceding chemical reaction has been studied theoretically and verified experimentally. The effects of parameters for peak currents are discussed. The cyclic additive current was obtained by adding the pulse currents with the same sense four times, thus the sensitivity was increased.
