| 摘 要： | 利用断电流法测定铝电解阳极电电位，用拟牛顿法确定过电位衰减极化曲线方程中的各项参数，结果表明采用拟牛地往往使得曲线的模拟结果与实验结果有一定偏差，从而影响其其预测功能，采用实数编码方法，把遗传算法应用于电位衰减曲线方程中的参数辨识，通过在遗传进化过程中动态改变交叉率和变异率以增加其全局寻优的机会，结果表明模拟曲线和实验结果相符很好。

| Abstract: | Anodic overpotential was measured by current interrupt technique, and the quasi Newton method was used to determine the coefficient of overpotential decay equation . The result indicated that a little difference exists between the fit data and the experiment data, which affects its predicting accuracy. So the genetic algorithm was introduced to recognize the parameters. Using real number coding, this algorithm was devised to change recombination rate and mutation rate dynamically, therefore more chance can be obtained to optimize the parameters overall situation. The simulated curve can be well agreed with the experiment result. [ |
