摘要：

A normal-state kinetic theory of copper-based oxides, which is an extension of BCS theory and Anderson localization to the strong-coupling limit lambda > 1, is proposed. In this limit carriers are charged 2e bosons (small bipolarons) below and above T(c). Temperature and doping dependencies of resistivity and Hall effect in copper oxides are explained by taking into account the localization of charged bosons in a random potential. Links with the 'spin' gap, high T(c) and with some other unusual properties are discussed.
