摘　　要：作者根据非牛顿液体的流动特性,推导出毛细管血液粘度仪的公式:剪切应力τ_a=apgh/2L剪切速率f(τ_a)=1/πa^3·[3q+h·(dq/dh)],据此公式设计和研制了血液粘度仪样机,对其重复性突验表明,该仪器性能稳定,剪切速率是同类仪器中最低的,粘度测定值误差最小。与锥板粘度计的对比实验表明,该仪器测试数据可靠。On the basis of specificproperty of non-Newtonian fluid (blood)we have worked out the formula of capil-lary blood viscosimeter: sheat stress τ_α=αρgh/2L shear rate f (τ_α)=1/πα~3[3q+h(dq/dh)] and designed and produced the pro-totype. Repetition experiments have indi-cated that the property of the instrument isstable, and a comparison of the prototypewith the cone and plate viscosimeter hasdemonstrated the reliability of the measu-rements.
