The quantitative relationship between blood pressure and blood stream of arteries, which is delineated by hemodynamics, is rather complex to understand and analyze mathematically. An equivalent simulated mathematical model was utilized to numerically describe this sort of relationship. The physiological essence of layered flowage inside the artery was opened out. The numerical simulation was accomplished using several sets of real parameters. Some important conclusions about quantitative relationship of the layered flowage were drawn through the simulation results. The research results presented in this paper have important reference value in respect of quantitative research of circulation physiology and clinical diagnosis and analysis of some illness within circulation system.
由血液动力学所描述的血压与动脉血流之间的定量关系,在数学上理解和分析起来相当复杂。利用一个等效的模拟数学模型对这种关系进行数值描述。揭示了动脉内部层流的生理本质。使用几组实际参数完成了数值模拟。通过模拟结果得出了关于层流定量关系的一些重要结论。本文给出的研究结果在循环生理学的定量研究以及循环系统某些疾病的临床诊断和分析方面具有重要的参考价值。
