Abstract

Abstract: By using the geometric method，two important formula in the radiation thermodynamics of the cavity are proved，namely，the relation between the radiation pressure and radiation energy density as well as the relation between the radiation energy passing density and the radiation energy density. The description and proving problems for the above two formula in the present textbooks are discussed.
