动脉波

So for the moment, we recommended in the newguideline that to measure pulse wave velocity, carotid artery pulse wave velocity which means arterial stiffness, because we have good evidence that it is an independent predictive value for cardiovascular events.

所以目前，我们在新的指南中推荐测量脉搏波速度，测量颈动脉的脉搏波速度，这个指标就是代表动脉僵硬度，因为我们有很充分的证据证明它对心血管事件有独立预示价值。

Experimental results show that, compared with the normal pulse, the wiry pulse has an increased PWV(P＜0.01 or P＜0.05), the thready pulse has a decreased PWV(P＜0.05),but the PWV of the smooth pulse is not significantly different from the normal's (P＞0.05). PWV highly correlates with the artery blood pressure.

实验测定的结果表明，弦脉的脉搏波速度比同龄组平脉有显著性增大(P＜0.01或P＜0.05)，细脉的脉搏波速度比同龄组平脉有所减小(P＜0.05)，而滑脉与同龄组的平脉相比无显著性差异(P＞0.05)；脉搏波速度与动脉血压之间具有很大的相关性。

The thesis discusses three eigenvalues individually and explains the pressure wave propagation of three modes, includes wave speed, wave decay and energy distribution. Since the elastic potential energy occupies more than 98% of mechanical energy in the arteries, which is larger than 2% of kinetic energy of flowing blood. Else join elastic wall and wall of managing having a viscid condition to analysis .

本文将个别讨论此三组特徵值，来说明三组压力波的传递模态，其中包括波速，以及波的衰减；由於在动脉的能量分布中，由管壁振动的弹性位能占了98%，远超过血液本身流动的2%，再加上管的弹性模数和管壁的黏滞性再来讨论此三组模态，个别在弹性管的能量分布。

Especially the formation of reversal gradient of blood pressure before the dicrotic notch.

特别是逆向血压梯度的形成，认为动脉血流的惯性及左心室的舒张是重搏波切迹前短时期内近心端血压低于远心端血压的主要原因，在动脉中存在着惯性动能与压力势能之间的相互转化。
