【摘要】 本文根据赵润屋的超声波实验结果提出血管的整体忙位移是脉象的新的科学解释。假设挠动脉切脉处的血管是一个在非对称载荷作用下的弹性简支梁,文章导出了位移函数的分折表达式及力学和生理参数对位移波的影响,并将它和压力波进行了比较.结果表明,位移波和压力波具有相似的波形,但具体数值不同。更多还原

【Abstract】 According to the ultrasonic experimental result of Zhao E. W., a new explanation of the pulse condition-the displacement wave of the radial artery-is proposed. In this paper an analytic expression of the displacement function and it’s variation with physiological parameters are derived under the assumption that the segment of the radial artery at which the pulse is felt is an elastic simple beam. Comparing the displacement wave with the pressure wave shows that they have similar wave form but different values.更多还原
