摘要：
The energy of the potential relief and of the Peierls barrier for a topological excitation (kink) in the Frenkel-Kontorova model is calculated in the continual limit to the second order of perturbation theory. A new method is proposed for analysis of the problem in a strongly discrete limit. Analytical results are compared with the results of numerical calculations.
