摘要：

The concept of granular temperature, introduced in the kinetic theory of rapid granular flow, is discussed here from experiments on a large air blowing table. Essentially, because granular systems are dissipative, the ''temperature'' is dependent on particle mass. This leads to a lack of equipartition. Then, granular temperature cannot be defined.
