摘要：

This paper obtains the adiabatic variation of the soliton velocity, in presence of perturbation terms, of the phi-four model and the nonlinear Klein-Gordon equations. There are three types of models of the nonlinear Klein-Gordon equation, with power law nonlinearity, that are studied in this paper. The soliton perturbation theory is utilized to carry out this investigation. (C) 2008 Elsevier B.V. All rights reserved.
