动脉的血流量与血压的空间和时间变化率同步
Synchonization of the Blood Flow Rate in Arteial with the Changing Rate of Space of Blood Pressure with Time
【摘要】 在生理学等相关书籍中多有关于动脉血流量与血压随时间变化关系曲线,但却未见对它们为何有如此关系做出解释,这正是本文力图解决的问题。研究以实验曲线为依据,借助泊肃叶定律和相关物理、数学知识,通过分析、推理而阐明血流量与血压梯度的关系。研究推断在一次心动周期过程中动脉血管中任一截面的血流量随时间的变化与该处血压的空间变化率和时间变化率大致同步。血流量与血压不同步。
【Abstract】 In physiology-related books,there are many relationship curves about blood flow rate in arteries and blood pressure changes with time,but there are not much explanation about such relationship.This is the very the question that the present article tries to answer.We clarified the relations between blood flow rate and blood pressure gradient using the experimental curves as the basis,using Poiseuille Law and relative knowledge of phisics and mathematics,and using analysis and reasoning.Based on the study,it can be concluded that in every course of cardiac cycle,the blood flow rate of any section in artery blood vessel is roughly synchronized with changing rate of space and time of the blood pressure,but blood flow rate is not synchronized with blood pressure.
【Key words】 Blood flow rate in arterial; Space changing rate of blood pressure; Synchonization of blood flow rate roughly with gradient of blood pressure;
