摘要：

The solutions within the mean-spherical and binding mean-spherical approximations of the sticky-hard-sphere model for colloids and polyelectrolytes are discussed. It is shown that the excess thermodynamic functions-the internal energy E, and the entropy S-have the same simple forms for all cases, and are functions of a single screening parameter Gamma(T), which however depends on ail the sticky interactions.
