本文提出了超微半扁球电极上循环伏安扫描可逆波理论,对不同p,g参数时电流、电位的性质进行了详细的讨论,并用汞超微半扁球电极在四氯苯醌-四丁基高氯酸铵-乙腈体系中的实验对理论进行了验证,实验结果与理论相符。

The theory of cyclic voltammetric revresible wave on an oblate hemispheroid ultramicroelectrode has been described in this paper. The behaviours of curent-potential curve at different p and g have been discussed in detail. In order to verify the theory, the experiments were carried out on different mercury hemispheoid microelectrode with TCBQ-TBAP-acetonitrile system. The experimental results agreed with the theoretical ones.
