✦ Synopsis

In the evaluation of thermodynamic measurements of mixtures a development of the excess Gibbs free energy, Ai@, in orthogonal functions has proved advantageous. Since measurements do not give a smooth curve but a set of discontinuous values, a method appropriate for the evaluation of equidistant discontinuous measurements has been developed, using VETTIN'S discontinuous orthogonal polynomials. The necessary formulae and tables are listed in this paper. R&urn&--Pour l'estimation des propri&& thermodynamiques des solutions, il est interessant de developper en series orthogonales la fonction Am, Bnergie libre d'exces de GIBBS (ou enthalpie libre d'exc&s). Comme les exp&-iences ne donnent pas une courbe reguliere mais une s&e de valeurs discontinues, il a fallu developper une methode convenable pour l'tvaluation de mesures discontinues bquidistantes, en recourant aux fonctions polgnomiales discontinues de VETTIN. Formules et et tables necessaires dans le m&moire.
