狗小肠粘液流变性能研究

Rheological Behavior of Dog’s Small Intestinal Mucus

通过试验研究了狗小肠粘液的流变特性。提出了狗小肠粘液Casson方程流变模型。试验结果表明 ,在低切变率下 ,狗小肠粘液的表观粘度随切变率升高而降低 ,具有剪切稀化的性质 ,属非牛顿流体。当切变率升高到一定程度后 。

The rheological property of small intestinal mucus of dogs was studied, and the Casson's rheological model of small intestinal mucus of dogs was obtained in this paper. The results obtained indicate that small intestinal mucus is a kind of Non-Newtonian fluid. Its apparent viscosity decreases with increasing shear rate. When the shear rate is high enough, the apparent viscosity of small intestinal mucus becomes a constant. [WT5HZ]
