摘要：

The screening of a highly charged grain immersed in a plasma background was investigated by means of the microscopic Monte Carlo simulations and within the Poisson-Boltzmann theory allowing for nonlinear effects. It was shown that a strong plasma-grain coupling causes, in a distinct contrast to the linear Debye-Huckel screening theory, the accumulation of the induced plasma charge on the grain surface, accompanied by a sharp reduce in the effective charge.
