Abstract

There were studied the procedures used to evaluate the relaxation parameters of the dielectric materials, corresponding to restricted intervals of frequencies (200 Hz … 100 kHz, or less, by means of the method of dielectrics spectroscopy), or to restricted intervals of temperatures (80 … 300 K, in frame of the method of thermally stimulated depolarization currents (TSDC)), respectively. There were studied: a) the choice of the zero-order approximations of the correlation parameters, b) the selection of the experimental results corresponding to a unique dielectric relaxation, c) the convergence speed of the iterative procedure, d) the compatibility of some studied theoretical models relative to the existing experimental data. The obtained results allow for the optimization of the data processing used for the evaluation of the dielectric relaxation parameters for restricted domains of frequencies or temperatures..
