摘要：

We present experimental observations of a fluidized state in a 2d vertical packing of beads submitted to vertical vibrations. The density field and the velocity distributions are simultaneously measured. The system is shown to reach a steady density profile but the state of internal agitation is dependent on the phase of excitation.
