M moments was loaded to simulate lumbar axial compression, anteflexion, extension, lateral bending and rotation. The stress of the pedicle screws was recorded.

m的力矩模拟腰椎前屈、后伸、侧屈和旋转等各种生理载荷，观察不同载荷下螺钉的应力分布。

MAIN OUTCOME MEASURES: Stress images and peak stress of pedicle screws under lumbar axial compression, anteflexion, extension, lateral bending and rotation.

主要观察指标：椎弓根螺钉在轴向压缩、前屈、后伸、侧屈和旋转等各种生理载荷下的应力云图和峰值。

A three-dimension FEM model of normal L4-5 was built, and the lumbar facet joints were treated as to contact with each other. Various motions of L4-5 were simulated by changing the loads: anteflexion, retroversion, right rotation, right bending and longitudinal compression.

本文建立了L4-5正常运动节段的有限元模型，将两小关节面处理为接触模型，分析了小关节面在腰椎前屈、后伸、侧弯、旋转及压缩运动状态下的受力情况，发现小关节在承载方面作用较大，特别是抗旋转运动过程中作用更明显。

Six cases were found to have normal direction of flow,but in the functional test of the involved upper limb,the reversal flow peak value of the ill vertebral artery increased,or the direction of flow turned from normal to reverse.2-dimensional ultrasound showed that 90% of subclavian steal syndrome were caused by arteriosclerosis,10% caused by aortitis.

结果 TCD检查时，24例患者中18例均表现为椎动脉血流反向，肢体束臂试验反向血流增加，6例血流方向正常，束臂试验患侧椎动脉反向峰值血流速度增快，或由正向变为反向。二维超声示引起锁骨下动脉盗血综合征的病因动脉硬化占90％，大动脉炎占10%。

Two methods show part hypoderma blood vessels of anterior and posterior aponeurosis branch and distal perforating branch, blood vessel morph of deep femoral artery can be show using the two methods.

二者均可显示前、后筋膜支和远侧穿支区域的部分真皮下血管，同时也可显示股深动脉穿支的血管形态。

Fold the side seam under and cut out the armhole.

All of them had tracheostomy before. The technique was to modification of Ossoff ECO2LA model. A small part of ventricular fold and posterior part of vocal cord was vaporized by laser. The mucoperichondrium overlying the arytenoid was reserved and sutured.

参照并改良Ossoff窥镜下杓状软骨切除术，汽化杓状软骨前部，包括声带突和部分肌突，一小部分室带及声带后端，保留粘软骨膜并缝合切口，以消灭创面，双侧分次手术。

On the basis of the 1 degree girded data of the seasonal mean temperature and salinity at standard levels in the South China Sea, mean Brunt-Visl frequency profiles were derived in order to compute numerically the vertical normal-mode for different seasons in various part of the South China Sea, and the associate linearized equation for horizontal large-scale waves is solved numerically with a improved thompson-Haskell algorithm.

根据南海1°×1°网格的标准层季节平均温、盐度资料，在未引入Boussinesq近似条件下，采用改进的Thompson-Haskell算法求解线性化斜压海洋水平大尺度波的垂直结构方程，从而得到了南海各网格点的第一斜压重力波相速度和相应的罗斯贝变形半径，并探讨其地理分布和季节变化特征，以期有助于南海环流和中尺度涡旋以及有关海洋侧边界效应的研究。

The producer surplus theory and consumer surplus theory were applied to deduce the cross subsidies among market participants in electricity pool under double auction mechanism, when market-wide system marginal price was used as settlement rule.

论文基于微观经济学中的生产者剩余和消费者剩余理论，推导论证了在对发电方和用户双侧开放的市场环境中，集中交易模式下采用全市场统一边际价格进行交易结算时产生交叉补贴的原因。

It turned out that he didn't take full advantage of his skills in using topspin, backspin, and sidespin returns.

结果，他没有充分利用自己在上旋、下旋和侧旋回击方面的优势。
