Calculation of equation of state of a material mixture under high pressure

At the same temperature, constituents of a material mixture are in temperature and pressure equilibrium by density-pressure iteration algorithm. Combining the adding principle, EOS of a material mixture was calculated by program. In order to verify this procedure, the parameters of state of different deuterium-tritium(DT) and argon mixtures are analysed. For DT doped with a small quantity of argon, the computed EOS agrees well with that of pure DT. Similarly, the EOS of argon with a little DT is in accordance with that of pure argon. The results indicate that the program is feasible.
