Abstract
Ways are discussed of describing dielectric spectra using the Cole–Cole distribution, constant phase element, and lognormal distribution. The central parts of the frequency dependences of the real components of the complex dielectric permittivity describe an experiment well in all cases. When using the Cole–Cole distribution, the high-frequency parts of the frequency dependences of the real components of the complex electrical conductivity do not agree with experimental findings. The lognormal distribution allows the width of the distribution to be associated with the physical meaning of the developing processes of relaxation polarization.

识别介电谱:科尔-科尔分布,恒定相元素和对数正态分布
摘要
讨论了使用Cole-Cole分布,恒定相位元素和对数正态分布来描述介电谱的方法。在所有情况下,复介电常数的实部频率与频率的关系的中心部分都很好地描述了一个实验。当使用Cole–Cole分布时,复数导电率的实数部分的频率依赖性的高频部分与实验结果不一致。对数正态分布允许分布的宽度与张弛极化发展过程的物理意义相关联。
