| 摘 要： | 研究了正常国人新鲜尸体膝关节软骨和骨性关节炎膝关节软骨的粘弹性力学性质.对正常和病态膝关节软骨进行一维拉伸应力松弛、蠕变实验,得出了应力松弛、蠕变实验数据和曲线,以回归分析的方法处理应力松弛、蠕变实验数据,得出了归一化应力松弛函数、归一化蠕变函数表达式.以冯元桢教授的准线性理论得出了正常组和病态组膝关节软骨松弛函数表达式,并对实验结果进行了分析讨论.

| Abstract: | To research on the viscoelastic properties of normal and osteoarthritis knee joint cartilage got from fresh corpse of Chinese. Did the stress relaxation tests and the creep test on them. Got the tests data and curves of stress and creep. Reduced the test data then by regression analysis method we obtained the reduced stress relaxation and creep function. By Feng YZ's the semi-linear theory we obtained the relaxation function of the normal and morbid group. |
