摘要
非均匀颗粒群体沉降现象在自然界相当普遍 ,本文分析非均匀颗粒群体沉速的试验方法 ,比较各种沉降试验和流态化试验 ,得到认识 :深度取样锥体筒流态化法是目前较好的试验方法。
The group settling of non-uniform grains is a very widespread phenomenon in nature, so a series of analysis on experimental method of it has been carried out in this paper. By comparing the methods of settling experiment and fluidization experiment, it can be considered that the method of fluidization experiment by sampling in cone-shaped tube is a better one at present.
