【操作系统】 EQS4WIN runs on Win XP/ME/98/95/NT/3.1 computers.

【用途】 One of the most significant features of EQS4WIN is its ability to solve problems both for which the problem free-energy data is available only as reaction equilibrium constants, as well as those for which individual species data is available (either obtained from its built-in database or supplied by the user).

Other special problem types uniquely treated by EQS4WIN concern the incorporation of Stoichiometric Restrictions (as arising, for example, via kinetic restrictions), and Equilibrium Constraints, by means of which an input feed composition may be determined from a specification of the target equilibrium composition. Treatment of these problem types was pioneered by the research of Prof. W.R. Smith and his colleagues.

The computational kernel which underlies EQS4WIN employs an efficient and robust free-energy minimization method based on more than 30 years of research of Prof. W. R. Smith and his colleagues. Prof. Smith, who acts as a consultant for Mathtrek Systems and supervised the development of EQS4WIN, "wrote the book on this subject". He is the senior author of the text Chemical Reaction Equilibrium Analysis: Theory and Algorithms, W. R. Smith and R. W. Missen, Krieger, Malabar, Fla, 1991; reprint, with corrections, of the same title by Wiley-Interscience, 1982.

     EQS4WIN Lite is a fully functional version, apart from problem size and input/output restrictions. It contains many example problem files illustrating its use for larger problems. The Lite Version includes only Version 1 features.
