Establishing an human spine dynamic model is an significan event to study spine injured biomechanics of pilot " s ejective injury, parachute opening, landing and study the endurance to impact loading on human spine. in this paper, the huston " s method of kane " s equations is developed so that it can be applied to the multibodysystem including translation between the bodyies. the dynamic model of human spine is provided basing on these theories, while the big movement of spine is considered. the deformation of vetebra is far smaller comparing with the intervetebra disc, so the spine is considered into multibodysystem including rigid bodies ( vetebra ) and the flexible bodies ( intervetebra disc ). the computer solution correspond with the results of the large scale human impact test. the rigid coefficient factors and the damping factor of intervetebra joints are obtained
人體脊柱動力學模型的建立對研究飛行員彈射救生、傘兵跳傘開傘、著陸等脊柱損傷的生物力學以及研究人體脊柱耐受沖擊載荷的極限問題都具有重要意義.首先發展了凱恩方程的休斯頓方法，使其可應用於變形體連接的多體系統，並以此理論為依據建立人體整椎脊柱沖擊動力學模型，此時考慮脊柱的大位移運動，每個椎骨的變形相對椎間盤的變形小得多，把脊柱看成由剛體（椎骨）和變形體（椎間盤）組成的多體系統.並以大型真人坐姿沖擊實驗結果進行了擬合，最後得到腰椎間關節剛度系數因子和阻尼系數因子Methods : after cultured scs combined with fn were grafted into hemi - resected lumbar spinal cords of adult rats, we used surface recording of spinal cord evoked potential ( scep ) and image analysis system to compare the latent period of scep and count the axon number between the therapeutic group and the control group
方法：將體外培養的雪旺細胞結合纖連蛋白植入大鼠半切損傷的脊髓內，用脊髓誘發電位及圖像分析方法比較治療組和對照組誘發電位潛伏期，再生軸突計數及二者間的關系。Results : in the group treated with scs and fn, the latency of p1 wave was significantly shorten and the number of regrowed axons significant increased, with a significant negative correlation
結果：雪旺細胞結合纖連蛋白治療組脊髓誘發電位潛伏期顯著縮短，再生軸突明顯增多，二者呈負相關。
