【摘要】 作者对10例19至51岁因头部外伤急死的新鲜腰段脊柱进行了粘弹性性质研究,试验在模拟人体屈曲生理状态下施行之。在100牛顿定载荷作用下测定腰段脊柱的松弛及蠕变效应。得出生理状态下,变形载荷—时间曲线和定载荷条件下的位移—时间曲线并给出归—化松弛方程及计算曲线。这些数据及实验现象不仅有助于解释脊柱的生理功能及超常运动,而且对临床上老年病的认识,旧术式的筛选及新术式的建立提供重要的理论依据。更多还原

【Abstract】 <ABSTRACT>Yiscoelastic properties of fresh lumbar vertebral column from malesubjects died of acute head injuries of 19-51 years old were tested, the testbeing performed by imitation of flexion of human lumbar vertebral columnand effects of load relaxation and creep deermined after application of loadof 100 Newton. The data obtained under essentially physiologic conditionare of theoretical importace including load-time, displacement-time andequation and caculation curve of reduced relaxation function.更多还原
