【Abstract】 Six basic types of gas liquid critical curves for binary systems have been analyzed and described.By the equation of state obtained from hard ball model which is suitable for high temperature and high pressure,critical curves of four systems are calculated.In calculations,there are only three adjustable parameters for each system.The calculated results are identical with the experimental values.更多还原
