In this paper electric circuit model was developed for experimental approach to study the human endurance to ejection. The human body is considered as an elastic body of single degree of freedom with low damping ratio. Its mechanical motion after the action of ejection force is similar to the current motion in the circuit of an electric oscillator. Their motion can be expressed by the same differential equation. When their natural frequency and damping ratio are the same, the electric oscillatory circuit can be used for experiments instead of human body. Natural frequency of 10.5Hz and damping ratio of 0.3 were selected for the electric model. Having transfered square waves, sine waves, triangle waves, trapezoid waves, discrete waves and overlapping waves into the electric circuit model, the output wave can be obtained. According to the amplitude of the wave, we can get the ratio value of input to output waves. If we know the amplitude of input wave, we can calculate the amplitude of the output wave from the ratio. The value of amplitude of output wave represents the magnitude of ejection overload acting on the human body. If we know the endurance capability to compressive stress of the vertebral bone, we can predicate the human endurance to ejection overload. According to this principle we have plotted the curve of human endurance vs. ejection overload.

本工作采用电子振荡线路模型对人体弹射过载耐力进行研究。人体是弹性体,他受到弹射力作用后的运动规律与电子振荡线路的电流运动相似,都可用相同的微分方程表达,只要它们的固有频率和阻尼比相同,电子模型即可代替人体进行实验。电子模型主要参数为带宽0~100多Hz,主固有频率10.5Hz,阻尼比0.3。将模拟的弹射信号输入到模型中去,即可得输出信号,它的波幅即代表作用在人体上的过载值,然后根据人体脊椎骨耐压强度,即可获得输入波形与耐力之间的关系。通过一系列实验,求得输入不同波形时人体的耐力数据和耐力曲线。

Objective To investigate the influence of posterior approaches on the stability of lumbar spine from the view points of biomechanics Methods Fresh human cadaver specimens of spine were used to form five different types of models,with test system of three dimension movement to measure the staility of lumbar spine,and then the results were compared with that of the intact type.Results There is no significant influence on lumbar stability following total laminectomy TL and bilateral fenestration,however,there was significant influence on lumbar stability after partial or total resection of facets;there was impairment of lateral bending,anterior flexion and rotational movement of the lumbar spine.Conclusion One should avoid injury of facet joints in lumbar operations through posterior approaches so as to maintain lumbar stability and reduce postoperative syndromes.

目的 从生物力学角度探讨不同的腰椎后路手术对其稳定性的影响。方法 采用新鲜人体脊椎骨制作成双侧开窗、小关节内侧半切除、小关节全切、全椎板减压及全椎板减压合并小关节全切共 5种手术模型 ,利用脊柱三维运动实验系统进行稳定性的测试和分析 ,并与正常组进行比较。结果 脊椎全椎板切除及双侧开窗对腰椎稳定性影响不显著 ,小关节部分或者全部切除则显著影响腰椎的侧弯、前屈和旋转活动度。结论 腰椎手术应尽量避免损伤小关节 ,以维护腰椎稳定性 ,减少术后并发症的发生
