根据镁合金微弧氧化微区电弧放电机理、微弧氧化的三个阶段理论，并根据实验中出现的，保持电压恒定时，在微弧氧化处理初期电流不断下降，后期电流保持稳定或微升这一现象，拟合出负载阻抗随时间变化的三次方程，从而实现了在实验过程中的膜层厚度监测，具有一定的工程应用价值。

Based on the micro-discharge mechanism of micro-arc oxidation (MAO) of magnesium alloys and the three-stage theory of micro-arc oxidation, and according to the phenomenon occurred in experiments, which is, while a constant voltage is maintained, current keeps declining at the beginning of micro-arc oxidation and be stable or increases slightly at the later mi-cro-arc oxidation, a time-varying load impedance cubic equation is fitted out, thus the film thickness monitoring during ex-periments could be realized, and it has a certain value in engineering.
