| Résumé : | The problem of demonstrating an H theorem for classically interacting moderately dense gases is discussed. In particular the H quantity recently given by Prigogine, George and Henin is studied in this case in detail. The H quantity is such that it takes into account those interactions which cause an irreversible increase in entropy. The remaining interactions serve only to redefine the natural units of the description of the system. It is shown that, in terms of their theory, considering both two- and three-body interactions there is an irreversible approach to a stationary state. This stationary state implies, for macroscopic subsystems, the correct values of equilibrium thermodynamic variables, at least to second order in the density. © 1973. |
