| Abstract: | The formula of a compressible factor was given and the compressible factor was eliminatedsuccessfully by the introduction of ghost field. A general expresion of equilibrium distribution function, isotherm Navier-Stokes equations and the range of equilibrium distribution function which meetsself-map conditions were obtained. |
