Double-dispersion impedance models are important for the accurate fitting of spectral impedance measurements in Electrical Impedance Spectroscopy (EIS). While the Cole-Cole model is the most widely known, it is possible to define double-dispersion Cole-Davidson and Havriliak-Negami models as well. In this work, we show that more freedom can be exercised when these three models are combined together and that this combination can be done in various forms. Experimental results using a two-stage optimization algorithm applied on the suggested models are provided.
双频阻抗模型对于准确拟合电化学阻抗谱（EIS）中的频谱阻抗测量非常重要。虽然科里-科尔模型是最广泛应用的模型，但也可以定义双频科尔-戴维森和哈夫利克-内伽米模型。在这项工作中，我们展示了这三个模型组合在一起时可以获得更多的自由度，并且这种组合可以以多种形式进行。我们提供了使用两级优化算法应用于建议模型的实验结果。
