摘要：

A theoretical study of dust-acoustic (DA) shock waves has been carried out in an unmagnetized electron depleted dusty plasma containing inertial negatively charged dust grains and nonextensive positively charged ions. The normal mode analysis is used to examine the linear properties of DA waves. The reductive perturbation technique is employed in order to derive the nonlinear Burgers equation. The basic features (viz. polarity, amplitude, width, etc.) of the DA shock waves are investigated. Both polarity (positive and negative potential) shock waves are found to exists in the plasma under consideration in this manuscript. The findings of this investigation may be used in understanding the wave propagation in laboratory and space plasmas.
