摘要：

采用2个共轴圆筒组成了一个环形容器,在竖直振动激励下,使颗粒物质在这个二维无水平边界的容器中振动,观察到颗粒物质出现显著的隆起及输运现象,通过跟踪拍摄方法测量了这种隆起运动对振动频率的依赖关系。

关键词: 颗粒物质;频率;隆起

Abstract:

Granular materials move in a twodimensional container under vertical vibration using an annular container made of two concentric cylinders in this experiment. It is obvious that granular materials are heaping and transporting horizontally. The relationship between the transformation of heaping and the vibration frequency can be clearly observed by video photographs.

Key words: granular materials; frequency; heaping
