摘要：
We perform a theoretical calculation of the effective temperature T(eff) for the high T(c) superconductor Y Ba2Cu3O7 as a function of the force constants in a lattice dynamic model. From the partial phonon density of states it is shown how Cu atoms might have higher frequency vibrations than O atoms and therefore higher T(eff).
