Studying the Dynamic of Granular Matter

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.
