人脊柱C5.6、T6.7、L4.5椎间盘归一化蠕变函数

The Normalization Creep Functions of C5.6,T6.7,L4.5 Interverbral Discs of Human Vertebral Column

报导了对 9例 1 9- 35岁新鲜 C5.6椎间盘 ,9例新鲜 T6.7椎间盘和 1 0例 L4.5椎间盘进行的蠕变实验研究。模拟人体温 36.5℃± 0 .5℃ ,对试样施加 30 0牛顿载荷 ,测定椎间盘蠕变效应 ,得出应变——时间曲线 。

In this paper are reported the creep experimental studies on 9 fresh C5 6 intervertebral discs,9 fresh T6 7 intervertebral discs and 10 L4 5 intervertebral discs that were taken from the bodies of ten men(aged 19 35 years)who had died of head injury 1 4 h before. By simulating the temperature of human body (36.5℃±0.5℃) and putting 300N load on the discs, we measured the intervertebral creep effects and obtained the strain time curves.
