From measurements of pressure and volume of a gas of spherical particles excitetd by a vibrating piston and undergoing inelastic collisions, we determine a state equation between pressure, volume, particle number and the vibration amplitude and frequency.

Nous utilisons des mesures de pression et de volume d'un gaz de particules sphériques excitées par un piston vibrant et interagissant par des collisions inélastiques, pour déterminer une équation d'état reliant pression, volume, nombre de particules, et amplitude et fréquence de vibration.

Key words: granular gas -- state equation
