Through simulation of the real process of thomcolumbar burst fracture and use of modem dynamics techniques, the present study was (1) to investigate the kinetic relationship between structural damage and impact energy absorption and dynamics mechanism of thoracolumbar burst fracture by quantitative analysis of various injured segments;(2) to explore the instability mechanism of L1 vertebral burst fracture and its injury threshold by three-dimensional analysis of the injured segment with stereophotogrammetry in combination of transient physical parameters, anatomy and image;(3) to explore the corresponding relationships between impact energy, geometry parameters and biomechanics by geometry and biomechanical analysis of thoracolumbar burst fracture, which may provide an objective standard for evaluation of spinal injury severity and experimental evidence for adoption of biomechanical treatment in clinic;(4) to evaluate the fixation effect of different instruments and the effect of intervertebral bone graft on segment fixation by analysis of the threedimensional stability of different internal fixation instruments and their decompression of the spinal canal, which may provide experimental evidence for therapeutical selection for thoracolumbar burst fracture in future; and finally to investigate the effect of various instrument fixation on dynamical characteristics by comparison and quantitative analysis of frequency and amplitude responses, which may provide certain theories and experimental evidence for application of vibration test to judge the stability of the spine.

Green Trade Barrier is a form of tariffless barrier which is risen in 1980s,its essence is to hamper other countries commodity to enter into importy countrys market by establishing stand of environmental protection and other measures, and this actions constitutes a substantive means of protection Developing countries is restricted and limited more easily than developed countries because of lowness of their economic and technology level, as a result, some dispute of trade are induced The rigorous proce...

绿色贸易壁垒是在20世纪80年代兴起的一种非关税壁垒形式，其表现形式是进口国通过严格的环保标准和其他措施，阻碍国外商品进入本国市场，构成实质性的贸易障碍。发展中国家由于经济及生产技术水平较低，容易受到其制约或限制，因而引发贸易争端。WTO争端解决机制所具有的严密的程序性、较高的透明度和公平性，将有助于发展中国家突破绿色贸易壁垒。当然，这种积极性作用也因WTO争端解决机制本身的某些缺陷而不能完全发挥。
