Statistical theory of associated-liquid structure

The above integral-equation system can be considered as a generalization of the Percus-Yevick approximation in the theory of simple liquids to the case of an associated liquid. It is familiar that the success of the Percus-Yevick equation is not a consequence of its being physically more sound than other integral equations, but rather it is determined by the successful reduction in the diagram types omitted in this approximation . Therefore, the proposed equations are to be, considered only as a first attempt to give a closed approximate description of the structure of an associated liquid on the basis of the integral-equation method. One will be able to judge whether the set of closing equations (25) is better in this case or whether it should be replaced by some other system only after comparing the solutions to (29) with results from a special computer experiment designed to simulate an, associated liquid.
