摘要
本文研究了微血管自律运动引起的血液流动,着重分析了血液的粘弹性质对压力升高及壁面摩阻的影响.结果表明,微血管自律运动具有人体“第二心脏”的作用,血液粘弹性质的影响与Weissenberg数及平均流量的大小有关.
This paper deals with blood flow caused by microvascular vasomotion with the focus on the effects of blood viscoelasticity on the pressure rise and wall resistance. It is shown that microvascular vasomotion plays a role of the 'second heart' of the body which is of importance in conveying blood, and that the effects of blood viscoelasticity greatly depend on the Weissenberg number and mean flow rate.
