着重介绍了剖分T型钢这种新型材料的研究现状，并对比关于T型钢腹板宽厚比限值的三种不同的理论观点，对三种观点进行了分析，使单轴对称截面压杆设计中比较复杂的弯扭屈曲问题得到有效的处理，从而使设计工作得以简化。

It mainly discusses on stability finite element method of out-spane flection.

重点讨论平面外屈曲稳定分析的有限元法。

Objective: To compare the different parameters of the patellofemoral joint in kinematic MR in normal and abnormal groups under various degree of flection.

目的：通过测量髌股关节动态MRI的一些参数，比较不同屈曲角度下正常人及患者之间的差异性。

Results: All parameters showed no difference at various degree of flection in the normal and abnormal groups respectively. The PTA and FTD at all degrees and FTA at 18 and 24 degrees were different between the two groups.

结果：各参数在正常组及病例组在不同的屈曲角度下组内均无显著性差异；PTA及FTD在所有角度下均有组间的显著性差异，FTA在部分角度下有显著性差异。

Rogowski coil can pass and will lead the line round on a pipe, then arriving pipe both ends flection together but constitute.

Rogowski线圈可以通过，并会导致线路回合对一个管道，然后到达管道两端均屈曲在一起，但构成。

PTA and FTD at all degrees and FTD at the 18 and 24 degrees of flection can be used to investigate the position of the patellofemoral joint effectively in kinematic MR and we suggest using the PTA, FTD and FTA at the 20 degree of flection in axial plane to study the patellofemoral joint in the future clinic.

动态MRI下的PTA及PTD可以很好的定量评价髌股关节的对合关系，FTD在18及24下也可以用来定量评价髌股关节的对合关系，建议在膝关节屈曲20左右进行MR检查测量PTA、FTD、FTA来定量评价髌股关节。

Geographical disaster resulted in soil movement and ground deformation, so buried pipeline will occur bend,compress,distort,rip,and part flection and other breakage activities.

地质灾害引发土壤运动和地表变形，从而导致埋地管道产生弯曲、压缩、扭曲、拉裂、局部屈曲等破坏行为。

Objective To investigate the effect of continuous passive motion and rehabilitation on flexion of the shoulder after intensive burn.

目的研究持续被动运动和康复疗法改善深度烧伤后肩关节屈曲功能障碍的临床效果。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
