颗粒在跳汰床层中分布形态的研究

The distribution shape of particles in jig bed

在大量试验的基础上 ,对不同密度颗粒在床层中分布的基本形态进行了归纳 .分析了颗粒分布形态与正态分布的联系和区别 .用四分位模型构成了有效描述颗粒在床层中分布的模型体系 。

Depending upon a great number of test data, the distribution shape of particles for different density fraction in jig bed were sum up. The relationship and difference between the distribution of particles and the Normal distribution was analyzed. A model system that is good for describing the distribution shape of particles in jig bed was set up and most of distributions were Non-Normal distribution.
