For this project, in virtue of the experimental observations on the vertical vibrator,the invert torsion pendulum and the vertical pipe with capillary outlet,and by using numerical simulations of the discrete element method, the mixing and segregation of granular materials of spherical and neraly spherical shape with the different size and different density under the vertical vibration or parallel shear motion have been researched, and the relationship between the macroscopic segregation properties and the microscopic characteristics of granular materials and the outer actions has also explored. The theoretical model and method describing the mixing and segregation of granular materials is developed.

本项目通过在垂直振动台、倒扭摆、带毛细出口的竖直玻璃管等装置上进行实验观测，并采用以离散元方法为主的数值模拟，研究了具有不同粒子尺寸、密度的球形或近球形颗粒物质在具不同结构形状容器中垂直振动和剪切运动时的粒子混合和偏析情况，探索颗粒材料流的宏观偏析特性与微观特征量及外部作用间的关系，发展描述颗粒物质混合和偏析的理论模型和方法。

Although these combined relative error γ.1%, in order to obtain more precise measurement results, it should be pay attention for the level of the torsion pendulum, the uprightness between the photoelectric doors and the block rod, the location of the being measured substance, the similarity of the shape and the quality between the standard object and the being measured object, human factors and so on.
