生物软组织的幂律形式松弛和蠕变函数

　　摘　要：本文利用幂律形式的松弛和蠕变函数，对一些生物软组织(如，软骨、动脉、输尿管、肠系膜等)的实验结果进行了分析，发现该形式能够揭示它们的力学特征。

　　Abstract：With the power-law relaxations and creeps, analysis on the experimental results of some soft tissues (i.e. cartilage, artery, ureter, mesentory etc.) was made. It was found that the power-law model could show up their mechanical properties.
