摘要：

The charge evolution of negatively charged dust grains during plasma expansion is investigated in the presence of Boltzmannian positive and negative ions. Using the self-similar treatment, it is found that the dust charge profile depends on the dust initial charge as well as on the negative ions density. (C) 2003 American Institute of Physics.
