Abstract： The fluid variational free energy model is applied to calculate the equation of state (EOS) of the fluid (Ne/3,2He/3) mixtures at 296K. The pair potential is used to describe the He--Ne interaction. The calculated EOSs at 296K are compared with the experiments for solid Ne(He)2. The validity of the potential and the calculated model is verified by comparison. The present model is extended to calculate the equation of state of the fluid He--Ne mixtures with different He:Ne compositions in the pressure 0--160GPa and temperature up to 10000K.
