The mechanical properties of costal cartilage specimens from cattle were tested under periodical compressive loads. The specimens were put between the compression plates of an electronic materials testing machine and were exposed to defined deformations and deformation rates. On the basis of these induced periodical deformation-time curves as input functions we obtained force-time curves as output functions.
(1) The cyclic force-time curves generated by deformation-time input functions with constant amplitudes initially showed a general decrease of force peaks until a force-time curve with constant amplitudes gradually arose. (2) If periodically loaded after a constant deformation had taken place the force peaks increased, at first pronouncedly but later diminishing. We named this the 'peak increase phenomenon'. (3) The mechanorheological curves of hyaline cartilage can be explained approximately by the viscoelastic behaviour of microfibrils in a parallel arrangement with the elastoviscous properties of cartilaginous ground substance.
对牛肋软骨标本在周期性压缩载荷下的力学性能进行了测试。将标本置于电子材料试验机的压缩板之间，并使其承受规定的变形和变形速率。基于这些作为输入函数的诱导周期性变形-时间曲线，我们获得了作为输出函数的力-时间曲线。
（1）由具有恒定振幅的变形-时间输入函数生成的循环力-时间曲线最初显示力峰值普遍下降，直到逐渐出现具有恒定振幅的力-时间曲线。（2）在发生恒定变形后进行周期性加载时，力峰值会增加，起初明显增加，但随后逐渐减小。我们将此称为“峰值增加现象”。（3）透明软骨的力学流变曲线大约可以用与软骨基质的弹粘性特性平行排列的微原纤维的粘弹性行为来解释。
