1.本文设计一种适用于沉淀悬浮体的循环式毛细管粘度计;提出“出流校正项”.2.证明浑水的流型曲线从2—3%(重量)开始就过渡为S型.3.结构稳定性系数χ是常数;它和含沙浓度γ的关系如下
A组χ=0.110γ1.63

B组χ=0.071γ1.63
γ的单位为公斤·米-3.4.无量纲准数Ψ=τ2/χ定量描述浑水的结构状态;当Ψ≥4.12,所研究的体系都达到结构的极限破坏状态.5.相对极限粘度与浓度的关系符合Orr等的经验公式.

1.A recirculating capillary viscometer suitable for the study of settling suspensions has been designed, and it is suggested that the out-flow correction must be taken into consideration.2.It is found that the rate of flow-stress curve of muddy water, when its concentration is larger than 2-3 wt.%，is generally of the sigmoid shape.
