摘要

The heap and covection of granular materials under vertical vibration are the complicated phenomena having a wide field of application, Although several formation mechanisms for various heaps and convections have been suggested according to the experimental observations and the molecular dynamical simulations, there exist their limitations or difficulties in these formation mechanisms. Some of them attributed the heap and convection to the horizontal restriction from the vertical walls of the container. The authors of ref. concluded that the friction between the vertical walls and the granular material, and (or) the spatial modulation of the excitation lead to the heap and convection. Obviously, these formation mechanisms are difficult to explain the soliton-shape heap and convection discovered by Chen recently because this kind of heap and convection formed in a narrow and long container, which means that this is a problem with infinite boundary in one-dimensional space. On the contrary, the shape of the heap is very similar to the water solitons or the envelope solitons in lattice. The purpose of this note is to experimentally look for dynamical formation mechanism for the soliton-shape heap and convection.
