Popis: 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.
