建立一种研究气泡对槽电压波动影响的方法，该方法将整个电解槽等效为一个电阻电路，并利用Matlab/Simulink仿真软件建立等效电路的仿真模型进行动态仿真研究，从而获得不同气泡状态下槽电压和阳极电流的时间序列数据，利用频谱和统计分析方法对这些数据进行分析。结果显示，较高的气泡释放频率对槽电压波动的影响更大，当一组阳极表面气泡覆盖率超过80%时，槽电压可能超出正常的波动范围。仿真结果证实了在实际生产中计算机监测到的阳极效应主要是全槽的阳极效应。

A method to investigate the effect of gas bubble on cell voltage oscillations was established. The whole aluminum electrolysis cell was treated as a resistance circuit, and the dynamic simulation of the cell equivalent circuit was modeled with Matlab/Simulink simulation software. The time-series signals of cell voltage and anode current were obtained under different bubble conditions, and analyzed by spectral and statistical analysis methods. The simulation results show that higher bubble release frequency has a significant effect on the cell voltage oscillations. When the bubble coverage of one anode block exceeds 80%, the cell voltage may exceed its normal fluctuation amplitude. The simulation also proves that the anode effect detected by computer in actual production is mainly the whole cell anode effect.
