摘要：
The viscoelasticity of blood is quantified by studying the oscillatory flow of suspensions of RBC in plasma in 218 mu m and 400 mu m glass capillary tubes. The flow conditions are chosen to reflect normal physiological flow in small arterial vessels. Data are obtained for suspension hematocrits between 35 and 80 percent, and at physiological temperature (37 degrees C). The results indicate that the elastic component of the viscoelasticity of blood is effectively negligible for the conditions of this study: the measured pressure gradient-flowrate relationship is dominated by the viscous component of blood viscoelasticity.
