摘要：

The thermal conductivity at T < 0.5K parallel to the CuO2 planes in single crystalline YBa2Cu3O6.9 can be decomposed as kappa-a,b(T) = kappa-phonon(T) + A.T, while kappa-c(T) = kappa-phonon(T). This is explained by a model calculation, assuming that superconductivity is generated in the CuO2 layers and weak superconductivity is induced in the CuO chains by the proximity effect.
