摘要: Taking into account the self-consistent dust charge variation, we use a Sagdeev potential approach to numerically investigate effects of negative ions on dust-acoustic soliton in negative-ion-contained dusty plasmas. It is shown that only can exist complex Also, presence significantly reduce both lower and upper critical Mach numbers. The profiles corresponding particle distributions ion free contained cases are illustrated discussed.
