摘要: 根据质量平衡和槽电压平衡原理,提出了析气电极电流分布的数学模型.在理论分析中应用了改进的Bruggman公式和电极遮盖度系数.采用微机控制的电位测量系统和组合电极实测了电流分布规律及其影响因素.结果表明,模型计算值与实验值能良好地符合.

Abstract: A mathematical model of secondary current distribution for the gas-evolving electrode is presented on the basis of mass balance and voltage balance. A modified Bruggman equation and the degree of electrode screening are used in the theoretical analysis. The current distribution and the factors affecting the distribution are determined experimentally with the segmented electrode method and a computer controlled voltage measurement system. The curves computed with the model show good agreement with experimental results.
