颗粒在介质中的沉降,是选矿、化工、冶金等领域中最常见的基本现象之一。虽然这一课题的研究,从斯托克斯(Stokes)和雷廷智(Rittinger)算起,已有上百年的历史。但是从准确、通用和简便三个方面来要求,已提出的公式并不都是令人满意的,所以到目前为止,还不断有人研究。 The sedimentation of particles in the medium is one of the most common basic phenomena in the fields of mineral processing, chemical engineering and metallurgy. Although the study of this subject has existed for centuries from Stokes and Rittinger. However, from the three aspects of accuracy, universality and simplicity, the formulas that have been proposed are not always satisfactory. So far, there are still some people studying it.
