摘　　要：用毛管粘度计测定悬浮液和非牛顿体的流变参数，必须注意∑效应（管径效应）的影响，但有关该效应产生的原因，至今仍不够清楚。本文根据泥浆测粘实验中长期的观察与体验，并在前人研究基础上，对其成因提出新的看法。When measuring rheological parameter of suspension and non Newtonian flow by capillary viscosimeter, the influence of ∑ effect must be avoided attentively, but the cause of producing the ∑ effect is not clear enough now. Based on the long observations and experience in slurry viscocity test, along with the pedcessor's results, this paper gives an analysis to the cause of this effect and also provided some new ideas.
