本實驗研究的目的在於探討血管橈度與脈搏波速關係，利用本實驗室開發之脈聲儀來測量模擬血管材料的橡膠管與矽膠管等彈性管的應變與應力關係，藉由此方式在彈性管受到應力作用時，將膨脹與收縮的效應全盤考慮。且利用兩個微型麥克風建立一個便利的測量脈搏波速的技術，這個創新的方式也發展出一測量模擬血管的彈性之方法。實驗結果顯示，橡膠管的彈性比矽膠管要好，且較矽膠管適合做模擬血管的實驗。而在測量脈波波速的實驗結果顯示，彈性越好的橡膠管其脈波波速將越慢，同時實驗結果也指出動脈硬化也將造成血管中脈波波速的增加。

The study of the relationship between the compliance of modeling vessel and pulse wave velocity has been done by using a pair of acoustic transducers. The two microphones build up an easy tool for measuring the pulse wave velocity. An innovative method also developed to measure the compliance of the modeling vessels. The results show that a rubber tube has much better compliance than a silicone tube. And it is more suitable to be used as a model vessel. The results of the pulse wave velocity measurement show that the better the compliance, the slower the pulse wave velocity. It also indicates the hardening of the artery would result an increasing of the pulse wave velocity in the vessel.
