摘要：
We report model calculations of a fluidized state in a two-dimensional packing of spherical beads subjected to vertical vibrations as recently experimentally studied by Clement and Rajchenbach. Using molecular dynamics we calculate the density field and the velocity distributions of the beads. We discuss the concept of fluidization and propose new ways to characterize it.
