The indirect decompression mechanism of the pedicle screw open the fracture vertebral and intervertebral discs ,strain posterior longitudinal ligament and intervertebral discs annulus tibrosus ,and push the bone pieces in the vertebral canal ahead to reduct, this process is Ligamentotaxis ,It is function depends on the completement of posterior longitudinal ligament and intervertebral discs annulus tibrosus.

椎弓根螺钉间接减压机制是通过椎弓根螺钉撑开损伤部椎体与椎间盘，紧张后纵韧带与椎间盘纤维环，将凸入椎管的骨块推向前方而复位，称为韧带整复。

The new algorithm uses the particle aggregation quality to judge that if the particles in the swarm are congregative so much,then apply the differential evolution to mutate the self prevenient best position of each particle,in order to realize the aim of preserving the varieties of the swarm.

该算法对于单调函数、严格凸或单峰函数，能在初始时很快向最优值行进，但在最优值附近收敛较慢。对于多峰函数，则更容易出现所谓&早熟&现象，即局部收敛[3]。粒子群算法出现&早熟&现象的主要原因是缺乏种群多样性。
