本文对固体颗粒在低粘度液体中悬浮所需的搅拌器转速和搅拌器尺寸进行了研究。结果以无量纲形式给出。通过这些经验关系式，可以在许多简单的情况下进行这种操作的设计。对于更复杂的系统，进行试验性实验可能会更好。讨论了缩放规则。作为完全混悬的标准，选择搅拌容器底部无固体物质的条件;未特别检查整个容器中混悬液的均匀性。结果与文献中的数据进行了比较。目前还没有从理论上考虑颗粒从底部上升的机制，但将继续对这一机制进行研究。
An investigation of the required stirrer speed and stirrer dimensions for the suspending of solid particles in a low viscosity liquid has been carried out. The results are given in dimensionless form. By means of these empirical correlations the design for this operation can be carried out in many simple cases. For more complicated systems it will probably be better to carry out trial experiments. Rules for scaling are discussed. As a criterion for complete suspension the condition is chosen that no solid matter rests on the bottom of the stirred vessel ; the homogeneity of the suspension throughout the whole vessel is not especially examined. The results are compared with data from literature. Theoretical consideration for the mechanism underlying the lifting of the particles from the bottom are not given, but research into this mechanism will be continued.
