Abstract: A generalized FK model is presented for treating phase transition problem with double-well interatomic interactions and a perturbed sinusoidal external potential,in which the interatomic interaction is of realistic significance.The effective potential method is used to study its phase diagram and a series of novel,complex but regular phase structures have been found.

Key words: CI transition, FK model, the effective potential
