卷积伏安法(新极谱法)是近十年发展起来的一种新电化学分析方法, 本文报导了逐级电子转移过程的0.51次微分电分析法的理论和实验结果, 用计算机模拟了理论极谱图, 讨论了标准分离电位和电子转移数对极谱的影响 。并选择0.1M的NH~4Cl-NH~4OH作为缓冲溶液中铜(II)的还原作为检验理论和实验之间的关系。

The theory of 0.5th order differential polarog. for multistep reversible charge transfers is proposed, and a theor. polarogram was computer simulated. The effect of both the standard potential separation (DE? and the no. of electrons on polarograms is discussed. The reduction of Cu(II) in 0.10M NH4Cl-NH4OH was selected to test the theory, and reasonable agreement between theory and experiment was obtained.
