Analysis is given of the changes of dislocation motion modes with stress and temperature variation. Different regimes of dislocation kink pair formation and spreading (motion in the random potential, in the field of random forces, the quasi-localization) are considered. Discrepancies are discussed between the theory and experimental data on dislocation velocities.
