本实验以新鲜的猪主动脉为供体血管，采用真空冷冻干燥的方法对其进行保存，并对新鲜血管和冻干复水血管的力学特性进行比较。结果表明：冻干复水血管的周向拉伸、轴向拉伸及穿刺过程曲线都分别与新鲜血管对应过程曲线的趋势比较接近，说明血管在冻干后结构成分及排列方式没有发生大的改变。研究结果为血管的移植应用提供必要的基础数据。

In this paper, fresh porcine aortas are used as donor blood vessels for experiment. The method of vacuum freeze drying to save vessels is adopted, and the mechanics characteristics of fresh vessels and rehydration vessels are compared. The results show that, rehydration vessels are close to the fresh ones in curve trends of three main processes:circumferential tension, axial tension and puncture, which suggests that there is no significant change in vessel structure composition and arrangement before and after freeze drying. The research result can provide the necessary foundation data for vessel transplantation application.
