摘要：

The mathematical model of dislocation glide movement is used to calculate the signal of acoustic emission that accompanies the defect overcoming in a crystal. The elastic stress in the emitted signal is estimated. It is established that the acoustic emission signal in the case of dislocation separation from a defect substantially exceeds the signal in the case of deceleration of a gliding dislocation on a defect. The shapes of these signals also differ.
