摘要：

Contrary to the usual interpretations, we experimentally show that the frequency-independent (dc conductivity) and frequency-dependent (polarization conductivity) conductivities of ionic glassy conductors can be considered to be independent of each other. Indeed, after having inserted two ionic glasses (Na2O.3SiO2,Ag2S.GeS2) between inert dielectrics, we observe that though the dc conductivity disappears, the polarization-conductivity behavior, i.e., the frequency power law, remains unchanged.
