摘      要：The correlation effects among the polaronic and one-phonon coherent and two-phonon squeezed states induced by the motion and density fluctuation of the electrons change the state and properties of the strongly coupled electron-phonon systems and make the ground state energy decrease, the binding energy of the polarons increase, the CDW ordering enhance and the quantum fluctuation effect of the lattice phonons weaken.
