摘要：

The dispersion relation is derived for current-driven dust-acoustic (DA) waves in a collisional plasma with dust grains having both positive and negative charges. The critical electric field is calculated for excitation of the two DA modes that are possible in such a plasma. Some numerical results are given for both a laboratory-type plasma and a cosmic-type plasma. (C) 2001 Elsevier Science Ltd. All rights reserved.
