Applying for Borland C ++ language,the software of the thermodynamic property database on coolant has been developed,which can calculate thermodynamic properties and refrigeration cycles performance in 18 kinds of coolant and their mixed coolant.

In view of the above mentioned facts, this paper proposes a set of very useful thermophysical property data of liquid and supercritical fluid for xenon, giving a reference to research workers.

Empirical formulas for thermophysical properties calculation of Pork, Beef and Cod;

Equations for calculating thermophysical properties of moist air;

The content and present testing accuracy of refrigerant thermophysical properties,environmental characteristics and evaluation guideline were introduced.

In order to obtain the thermal properties required in the processes of cold storage,fast-freezing and vacuum freeze-drying of Lychee,based on established data,the equations for predicting the specific h ～t and t～xice/ x w0,as well as regression equations of ρ,c and k of Lychee pulp were obtained and shown.

But it is unfortunately that these methods, when being used to calculate the thermal properties of some materials at high pressure, are either too inaccurate or too intensive in computation.

the collection and test for thermodynamic property data, and the usage and test for thermodynamic models are discussed.
