宾汉体是宾汉(E.C.Bingham)于1919年提出的一种理想物体,即在承受较小外力时物体产生的是塑性流动,当外力超过屈服应力t时,就按牛顿液体的规律产生粘性流动。
...×102Pa,表观黏度只有0.5Pa·S,接近于室温时中等牌号发动机机油的黏度,这说明半固态金属的流变性能犹如宾汉体(Bingham body)的流变性。

Finally, the paper shows that the rheology model con be stated in the form of the plastic-viscous Bingham body.
宾汉体在流动时候,离边壁远的地方经常会产生塞流现象。
When Bingham fluid is in motion, plugged flow often occurs at places far from the boundary -walls.
结果表明,似膏体料浆在较高浓度近似呈宾汉塑性体,在管道中的流态属于层流。
The result shows that the rheological model of paste-like slurry is similar to that of Binhan and its flow state in pipeline transportation is of laminar flow type.
