Perfect Gas Pressure of 2-phase Space and Physical Adsorption
Yang Xue-te · 2004
This paper ascertains perfect gas pressure of 2-phase formula by way of analogy and makes dimensional analysis of its result in order to make sure of its micro effect. Moreover,it illustrates the physical nature of two basic ways of improving vacuum degree through working out the relationship between thermodynamics function:U(internal energy),S(entropy),F(Gibbs free energy) and work of escape when the perfect gas in vacuum adsorbs and desorbs.
