| Abstract: | According to the general exergy function of thermodynamic system,the paper has made a general proof that the exergy of the closed thermodynamic system is positive and pointed out that if only these exists some difference on intensity amount between system and environment,the related outside could achieve the useful work when the system changes to its stationary state. The result mentioned above indication that calculation of the exergy is also with out exception when the system of steady flow is below the pressure of the environment. |
