【摘要】The theory of dynamical (wake) potential behind a moving test charge in a weakly coupled dusty plasma is extended to that including of strong interaction between dust grains.Such strong interaction is included in the dielectric response function by a generalized hydrodynamic (GH) fluid model.It is shown that the strong interaction between dusts including the lattice spacing correction has a significant effect on the wake potential in dusty plasma.This may be used to investigate basic features of phase transition and possibility of lattice formation of dusty plasma. 【总页数】6页(111-116) 【关键词】
