A REVIEW OF COMPUTER-PROGRAMS PERFORMING THERMODYNAMIC CALCULATIONS USING IN THE USA IN GEOCHEMICAL STUDY OF UNDERGROUND WATER - COMPUTERIZATION SYSTEM OF THE USA SCIENTIFIC LABORATORIES

Advantages and restrictions of the computer programs have been discuss ed performing thermodynamic calculations using in the USA in geochemic al study of underground water. Systematic hierarchy has been given for the programs concerning different processes taking place in heterogen ic systems water - rock: adsorption, redox, e.t.c. A list of the progr ams developing for the high temperature processes and for brains as we ll has been presented. A system of using and development of computer p rograms for thermodynamic calculations has been described.
