人体外周动脉是粘弹性的薄壁小园管,前辈学者将动脉血管作为生物材料对它的受力形变关系以及管壁对压力波传播的非线性弹性效应作过有益的研究。但是由于构成动脉血管壁的平滑肌随神经体液机能状况而变,它通过血管牵张感受器和神经反射作用随血管内压力的变化而变化,为了能够了解在完整机体生命活动条件下,外周动脉血管在压力波作用下的形变运动,作为循环动力学讯号检测技术建立数学模型的基础,
The human peripheral arteries are viscoelastic thin-walled tubes. The scholars of the previous generation used arterial blood vessels as biomaterials to do useful research on its force-deformation relationships and the nonlinear elastic effects of pressure waves on the wall. However, because the smooth muscle that constitutes the arterial blood vessel wall changes with the function of the neurohumoral fluid, it changes with the pressure in the blood vessel through the vascular stretch sensor and nerve reflex, in order to understand that the peripheral arterial blood vessel is in the complete body life activity condition. Deformation motion under the action of pressure waves serves as the basis for the establishment of a mathematical model for cyclic dynamic signal detection technology.
