摘要：

We obtain the equation of state for a charged colloidal solution, which is represented by a collection of sticky charged hard spheres. The mean spherical approximation (MSA) is used for the ionic part, and the Percus-Yevick (PYA) approximation is used for the sticky part. Explicit expressions are obtained for the pressure in terms of a sticky parameter lambda and a screening parameter Gamma. The pressure diagram indicates a first order phase transition characteristic of colloids.
