提出了由扩散和在滴汞电极上反应的物质再生的催化过程的速率控制极谱电流的理论。本文导出了催化电流的性质，并报道了一种从实验电流中确定速率常数的图解法。该理论适用于在过氧化氢的存在下还原铁离子中观察到的催化电流。计算值与实验值吻合较好。
The theory of polarographic currents controlled by diffusion and by the rate of a catalytic process which regenerates the substance reacting at the dropping mercury electrode is developed. The properties of catalytic currents are derived and a graphic method for the determination of rate constants from experimental currents is reported. The theory is applied to the catalytic currents observed in the reduction of ferric ion in presence of hydrogen peroxide. Calculated and experimental data are in good agreement.
