摘要：
A simple model of electrical resistivity for some copper oxides, in the normal state, and at low temperatures, is given. We show that the logarithmic temperature dependence can be obtained taking into consideration a non-Fermi-liquid model with a singular density of states and in the presence of randomly distributed nonmagnetic impurities, without taking into consideration the localization effects.
