| Abstract: | The weak interaction universally exists in actual gases,the analytical expressions of chemical po- tential,pressure,entrophy and heat capacity at a constant volume for actual gases in the absence of external po- tential are derived using total energy deduced by pseudo potential method,then based on the derived expres- sions,the effects of inter-particle interaction on the properties of Fermi gas systems are discussed. |
