摘要：

The analytic theory of 4 pi-kinks in long Josephson junctions is presented. The laws for the velocity "quantized" spectrum of the different modes of the moving 4 pi-kinks nonlinear vortices are obtained. The discreteness of the velocity spectrum is dictated by the condition of the phase matching of the nonlinear state which does not permit breaking of the vortices due to the Cherenkov radiation.
