摘　　要：作者导出了包括氧化铝中α-Al2O3含量、电流效率、电解温度和室温四变量在内的理论能耗和理论能耗电压计算公式。进一步提出铝电解技术参数相互适应原理,根据这一原理,随着电解技术条件的改变及时调整能量平衡,电流效率将会提高。An equation to calculate the theoretical energy consumption and theoretical energy consumption voltage was presented in this paper. It is a function of α - Al2O3 fraction in alumina, electrolysis temperature, current efficiency and ambient temperature. Furthermore, a principle adapting energy input to change of electrolysis process conditions was presented, and the current efficiency can be increased by adjusting the energy balance according to this principle.
