摘要: 本文旨在用电模拟方法深入研究了极谱法测溶解氧电极扩散传质过程的数学模型.综合微电极和脉冲操作技术提出了改进目前使用的Clark电极特性的途径,并以无因次的形式定量地给出了电极尺寸和操作条件之间的关系曲线和讨论了最佳操作范围.

Abstract: The mathematical model of diffusion process in polarographic determination of dissolved oxygen has been thoroughly studied with an electric simulator. It is found that the combination of microelectrode and impulse operating technique is a possible way to improve the characteristics of present Clark electrode. The quantitative relations between the electrode size and operating condition are given in this paper in dimensionless form, and the range of the optimum condition has been discussed.
