| 摘 要： | 简述颗粒物质研究的历史和颗粒物质研究的现状,以及颗粒物质研究的重要意义、通过实验得出：圆筒底面所受压力会随圆简直径增大而增大,但达到饱和压力后就不再增大,同时圆筒底面压力会随颗粒直径增大而增大;平面传送带的流量主要受传送带的速度和瓶颈开口大小的影响,但在一定瓶颈开口大小下,存在临界速度,流量关系会发生突变。

| Abstract: | The history, actuality and significance of the granular matter research are briefly introduced firstly. The results shows in two experiments: 1) The pressure force on the cylinder's subface will change as the diameter of cylinders in the same direction and not change until it reaches saturation. In the same time, the pressure also will change as the diameter of granules in the same direction. 2) The quantity of granules on the flat conveyer is influenced by the velocity of the conveyer and the size of the exit. There is a critical speed and a saltation of the quantity of granules under a certain size of exits. |
