Résumé

Cet exposé traite du problème de la plaque chaude gardée et résume les travaux de Somers et Cyphers, de Pascal, Woodside, Pratt et Donaldson qu’il complète par des résultats expérimentaux sur les mesures de déséquilibre faisant suite aux travaux de Pascal, et donne une précision supplémentaire par la mesure directe des flux. On attire également l’attention sur l’intérêt de compléter les dispositifs lorsque la température moyenne de la mesure est proche ou inférieure à celle de l’environnement.

Summary

This paper deals with the problem of the guarded hot plate and sums up the works by Somers and Cyphers, Pascal, Woodside, Pratt and Donaldson which are completed with experimental results on the unbalance effect, as a continuation of Pascal’s works, and a supplementary precision is given concerning the direct measurement of heat flow. Attention is called as well to the interest of measures under low gradient and to the necessity of completing the devices when the mean temperature of the measure is near or inferior to the room-temperature.
