【Abstract】 Based on the reduced parameter,the equations for equilibrium vapor pressure and density of hydrogen isotopes have been derived,which can be used below the critical point of D 2.It is shown that the calculating results of the saturated vapor density with the corresponding state method is more accurate than that with the dew point method,and that Benedict Webb Robin equation is more reasonable than the ideal gas equation for calculating the filling pressure.更多还原
