The stress relaxation and creep test were performed. For normal and abnormal meniscus, the slope of relaxation curve G (t) with In t ATr is -0.1179 and -0.0856, Ge (the value of G(t) at the end) is 0.5250 and 0.5710 respectively. For normal and abnormal cartilage of femoral head, the Kr is -0.101 4 and -0.063 3, Ge is 0.591 5 and 0.6632 respectively. For normal and abnormal meniscus, the Kc (the slope of creep curve J(t) with In t) is 0.208 0 and 0.109 5, Je (the value of J (t) at the end) is 1.953 8 and 1.493 1 respectively. For normal and abnormal cartilage of femoral head, the Kc is 0.167 3 and 0.120 7, Je is 1.854 9 and 1.599 8 respectively. The stress relaxation and creep quantity of abnormal specimens evidently move less than that of normal group. The main reason is collagen degeneration and decrease in proteoglycan.</em></p><p class='subject'><strong>关 键 词：</strong><a href='/zk/search.aspx?key=K%3d%5b%e4%ba%ba%e8%82%a1%e9%aa%a8%e5%a4%b4%e8%bd%af%e9%aa%a8%5d' title='人股骨头软骨'>人股骨头软骨</a> <a href='/zk/search.aspx?key=K%3d%5b%e4%ba%ba%e5%8d%8a%e6%9c%88%e6%9d%bf%5d' title='人半月板'>人半月板</a> <a href='/subject/article.aspx?id=3726170' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e9%bb%8f%e5%bc%b9%e6%80%a7%5d' title='黏弹性'>黏弹性</a> </p><p class='class'><strong>分 类 号：</strong><a href='/zk/search.aspx?key=C%3dQ66' title='Q66'>Q66</a>[<a href = '/domain/article.aspx?id=106' >生物学—生物物理学</a>] <a href='/zk/search.aspx?key=C%3dR318.01' title='R318.01'>R318.01</a>[<a href = '/domain/article.aspx?id=469' >医药卫生—生物医学工程</a>] </p>
