中文摘要：

皮肤组织生物热力学是一门涉及生物传热、烧伤、生物力学和生理神经学等的高度交叉的新兴学科．皮肤组织的热力学性能表征对皮肤组织生物热力学的建立和完善以及许多医学应用领域都具有相当重要的作用．然而，目前对于皮肤组织力学性质和温度之间的量化关系却几乎没有开展研究，试图揭示高温引发的热损伤对皮肤组织力学性能影响的研究也相当少．该文重点描述了猪皮在各种热损伤度下的压缩行为，讨论了与热损伤与皮肤压缩行为的相关性及机理．结果表明：皮肤的刚度随热损伤度的提高而下降，并且具有不同损伤度下的应变速率敏感性，这此特性主要是由皮肤的水合作用变化所引起的．

英文摘要：

Biothermomechanics of skin tissue is highly interdisciplinary, involving bioheat transfer, burn damage,biomechanics and physiology. Characterization of the thermomechanical behavior of skin tissue is of great importance and can contribute to a variety of medical applications. However, few studies attempted to address the influence of heat induced thermal damage on the mechanical properties of skin tissue. This paper presents the compressive behavior of pigskin at different thermal damage levels and discusses the possible mechanisms of thermal damage-dependent compressive behavior of skin. The results demonstrate that skin stiffness decreases with increasing thermal damage degree and there exist strain rate sensitivity at different damage levels, caused mainly by hydration changes.
