摘要：

An analytical method is presented, on the basis of a discrete model, for evaluation of the potential barrier to be surmounted when the stable commensurately modulated structure is displaced by one lattice distance. A concrete example is given for the case where there occurs a phase transition between two commensurate phases with the same modulation period.
