We report a complete set of experimental determinations of the superfluid onset temperature in film mixtures at four different coverages. For each coverage the data show a linear concentration dependence. At low temperature we observe a discrepancy between the third sound velocity measured at the onset temperature and the calculated one.Nous avons mesuré la température de transition superfluide dans des films de mélange correspondants à quatre taux de recouvrement différents. Pour chacun d'eux les résultats expérimentaux montrent une variation linéaire de cette température de transition en fonction de la concentration. A basse température, la valeur de la vitesse du troisième son mesurée à la transition devient très différente de celle calc...
