  A (1+1)-dimension equation of motion for \phi^4 theory is considered for the
case of simultaneou taking into account the processes of dissipation and
violation the Lorentz-invariance. A topological non-trivial solution of
one-kink type for this equation is constructed in an analytical form. The
modofied Hirota method for a solving the nonlinear partial differential
equations is applied. A modification of the method led to the special
conditions on parameters of the model and solution.
