摘要：

A simple model for polyion-polyion attraction inside a polyelectrolyte solution is presented. It is shown via calculations that the attraction results from the correlations between the condensed counterions. Consistent with the experimental evidence, the attraction exists only in the presence of multivalent counterions.
