血浆层对小血管中脉动流的影响

本文研究了血浆层的存在对小血管中脉动流的影响。分析表明,在小血管中血浆层的存在可以明显改变脉动血流量的峰值,但几乎不改变血流量的相位。也就是说,在一定的压力梯度下,由于血浆层的存在,血管中血流量的脉动幅度可大大增加,这对人体血液循环有特殊的生理意义。

The Influence of a Plasma Layer on Pulsatile Flow in Small Arteries

This paper presents the influence of plasma layer on the pulsatile flow in small arteries. The analysis demonstrates that the existence of the plasma layer may obviously increase the modulus of pulsatile flow, but hardly change the phase of pulsatile flow. That's to say, under a certain pressure gradient, the amplitude of blood flow harmonic wave can be greatly increased because of the plasma layer existing near the vessel wall. This has special physiological significance in blood circulation system.
