摘　　要：本文研究了双极流体通过带有轴对称柔和狭窄的刚圆管时的流动特性。运用Bleustein和Green的双极流体理论,导出了速度剖面、流量、阻抗和壁面最大剪应力的公式,并做了数值计算,分析了狭窄度与双极参数对上述有关量的影响。In the paper, the flow characteristics of dipolar fluid through a rigid circular tube with an axisymmetric mild stenosis are studied. The expression of velocity profiles, flow flux, the resistance to flow and maximum wall shear stress are derived using Bleustein and Green's dipolar fluid theory. The numerical computations are performed and the effects of stenosis size and diploar parameters on those quantities above are analyzed.
