摘　　要：本文提出了微环电极上线性扫描伏安法可逆波理论,对电流、电位的性质进行了详细的论述。得到了P≤1,γ≤40适用的峰电流经验式。用微金环和铂环电极在K_4Fe(CN)_6·KCl体系中进行了实验验证,结果与理论相符合。In this paper, the theory of reversible wave for linear sweep voltammtry at microring electrode is described. The behaviours of current—potential curve are discus sed in detail. The maximum current is expressed by an approximate equation which is valid for P≤1 and γ≤40 of the microring electrode. In order to verify the theory, the experiments were carried out on gold and platinum microring electrodes with K_4Fe(CN)_6 in 0.5 mol·dm^(-3) KCl solution. The experimental results are in good agreement with the theoretical ones.
