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 phenomenon of nonuniform particle population settling is quite common in nature. In this paper, the test method of non-uniform particle population settling velocity is analyzed, and various settlement tests and fluidization tests are compared. It is known that the deep sampling cone barrel fluidization method is currently better Test method.
