The publication presents a set of equations and constants for calculating thermodynamic properties of refrigerants. State equation, equation of saturated vapor pressure, equation of liquid volume, equation of specific heat capacity, enthalpy and entropy for R11, R12, R13, R14, R22, R23, R113, R114, R500 and R502 are presented. High accuracy of results was achieved in comparing with ASHRAE tables. All equations are in SI units.  相似文献

Robert Burns Woodward is considered one of the greatest synthetic organic chemists of our time, if not the greatest. This article presents evidence that Woodward was also one of the greatest physical organic chemists as well. Among Woodward and his collaborators' most important accomplishments in the field of physical organic chemistry are: the Woodward–Hoffmann rules; the derivation and use of structure–mechanism–reactivity relationships in his multifold structure determinations and total syntheses; the Woodward ultraviolet rules and the Octant Rule; and his early demonstration that synthetic organic chemistry can contribute to the synthesis of potential superconductors and thus, to material science.

The successful investigations of r.f. effects in NGR were recently in progress [1–3]. The purpose of this paper is to pay attention to some new theoretical results in this field which may be an object of the experimental realization.  相似文献
