A series of radial distribution function, configuration energies and pressure for symmetrical electrolyte model fluid of 1 :1 and 2:2 type under varied conditions were obtained by using Monte Carlo simulation of NVT canonical ensemble. It is of great significance for constructing a new reference fluid of electrolyte solution. The electrolyte solution is represented with a mixture of charged and dipolar hard sphere. The structural orderness and thermodynamic properties of ion-dipole mixture as well as their parameters dependence on temperature, concentration and total density were discussed.
