• A dislocation in a material of high Peierls barrier moves in a direction of an external force by successive forrnation of a new pair of kinks and by propagation and amihilation of the kinks. Dislocation velocity depends on a formation rate and on a propagation velocity of the kinks. A computer simulation gives that the moving dislocation is not a straight line but is distributed over many Peierls valleys containing many kinks. It also gives that, 1) an average dislocation velocity is approximately proportional to the geometric mean of the formation rate and the propagation velocity, and 2) the distribution of dislocation segnlents is not truly stationary but quasi-stationary within the time of a present computation. A new treatment of the average dislocation velocity reproduces results given by the computer simulation approximately.
