摘　　要：In order to substantiate the applicability of the Takayama-Lin-Liu-Maki model to conducting polymer,the Su-Schrieffer-Heeger model is generalized to include the effects of lattice zero-point motions on electronic properties.Beyond the treatment of the white-noise approximation,some significant electronic properties of Peierls-Fröhlich states are documented.The finding shows that the correlation of lattice motions suppresses the effects of zero-point motions on the electronic properties more seriously.
