| 摘 要： | 本文利用稳定性涡流模型，以Casson方程作为血液的本构方程，研究了具有不同屈服应力的血液在圆管中流动的稳定性问题，建立了判别其流动状态的判据，获得了广义临界雷诺数、临界压力梯度与管径的变化关系。为在层流条件下的血流动力学、流变学以及体外模拟等理论或实验研究提供了稳定性方面的理论依据。

| Abstract: | The flow stability of blood represented as Casson equation in pipe was studied by means of stability eddy model in this paper. The criterion used to judge flow state, the relationship between vasal redius and critical Reynolds number, as well as critical pressure gradient were established. A theoretical Method of stability was provided for further theoretical and experimental research under laminar condition such as Cardivascular fluid dynamics, Biorheology,Simulation in vitro, etc. |
