摘　　要：从化学反应动力学基本方程出发、结合有关复杂电化学反应理论的两条基本原则(并行反应独立原理和极化曲线叠加原理)并用表观速率常数来包容传质系数的方法,建立恒温、恒容、恒电位操作条件下的草酸电还原反应的电化学工程模型。本文还探讨了用电流观测法解析复杂电化学反应的表观动力学常数的可能性,并用该方法对模型进行了验证。Electrochemical engineering model for electro-reduction of oxalic acid was developed by starting from the basic equation of chemical kinetics,combining with the two basic propsitions of the electroche- mical theory of simultaneous reactions(principle of independence of simultaneous reactions and that of superposition of polarization cur- ves)and using the apparent kinetics constants for covering mass tr- ansfer coefficients.The model was proved by the determining reaction currents.
