摘要：
The mechanical and dielectric loss spectra of ZrO2-Y2O3 and ZrO2-CaO indicate the presence of associates (dipoles) consisting of dopant cations and oxygen vacancies on nearest neighbour sites, with trigonal defect symmetry. Reorientation of the dipoles is connected with a polarization current, which should be considered in the analysis of AC impedance measurements.
