摘要：
Two experiments have been carried out to understand the physical characteristics of surface heap and internal convection of granular material subjected to vertical vibration. The results show that they have a clear auto-amplifying behavior. An effective force leading to the heap and convection has been obtained, which includes the square and cubic terms of the local height.
