This work presents a new approach to the analysis of immittance spectrograms of systems characterised by non-stationarity. The possibility of linking the evolution of the immittance response with changes in the parameters describing the system is achieved by introducing a spectrum in differential form. By using the above procedure, it becomes possible to separate elements with a dependence (or lack thereof) from an independent variable appearing in the dynamic electrochemical impedance method. The work illustrates the usefulness of this approach for the elementary components used to model the behaviour of electrochemical systems.

动态阻抗谱的差分分析

这项工作为分析以非平稳为特征的系统的阻抗谱图提供了一种新方法。通过引入差分形式的频谱，可以实现将阻抗响应的演变与描述系统的参数变化联系起来的可能性。通过使用上述过程，可以将具有相关性（或不具有相关性）的元素与动态电化学阻抗法中出现的自变量分离。这项工作说明了这种方法对于用于对电化学系统行为进行建模的基本组件的有用性。
