摘要：

Within mean field theory we reexamine the collective modes associated with the phase fluctuation in the presence of long range Coulomb interaction. We find that the phason propagator is dominated by an acoustic mode and an optical mode. These modes have already been described by Nakane and Takada and Wong and Takada. However, due to their inconsistent approximations, their results became unreliable; particularly in the vicinity of the transition temperature. Relevance of these modes to those found in the Raman and neutron scattering from blue bronze is briefly discussed.
