AsTher Thermodynamic Database and Applications**

1. Database Administration: Modification, administration and creation of thermodynamic datasets.

2. Pure Substance: The values of the state functions can be shown in tables or graphics in depend of temperature or pressure.

3. Reaction The change of the state function by reactions can be shown in tables or graphics in depend of temperature and pressure

4. Equilibrium Calculation of a thermodynamic equilibrium. By variation of the system conditions e.g. temperature, pressure and mass and composition of substances, the results of several calculations can be shown as table and graphic in depend of the variant parameters.

5.
Recalculator, Calculation of concentrations as well as estimation
of
the temperature and pressure in an equilibrium state
corresponding to the given conditions or
measurements.
