英文摘要	The effects of the nonthermally distributed ions, the external magnetized field, and collisions on 3-D nonlinear dust acoustic solitary waves in inhomogeneous hot dusty plasmas have been investigated theoretically. A modified variable coefficients Korteweg-de Vries (MKdV) equation governing the 3-D nonlinear dust acoustic solitary waves have been derived by the reductive perturbation method. The approximate analytical solution of standard variable coefficients KdV equation derived from modified variable coefficients KdV equation has been obtained. This approximate analytical solution shows that nonthermal ions, inhomogeneity, collision, the oblique propagation of waves, the temperatures of dust and ions have effect on amplitude and width of 3-D nonlinear dust acoustic solitary waves. The amplitude of solitary waves is independent on the external magne-tized field, but the width of solitary waves is dependent on the external magnetized field. Moreover, The phase velocity of waves is dependent on nonthermal ions, the oblique propagation of waves, the temperatures of dust and inhomogeneity.
