Methods Six cadaveric lumbar vertebrae were harvested and evaluated with dual-energy x-ray absorptiometry and quantitative computed tomography to assess bone mineral density. Matched, polyaxial pedicle screws were then randomly assigned by side and placed using the Magerl, Krag or caudad trajectory technique assisted by Iso-C 3D scan and 3D navigation system. Cyclic loading tests were performed with a maximum 250 N load at 3 Hz up to 30000 cycles while recording load and displacement. Stiffness quotients were calculated it comparison.

从尸体中获取6节腰椎椎体经DEXA和QCT检测骨密度值，证实为骨质疏松后在计算机导航下按随机分组的方法向12个椎弓根中置人不同方向的椎弓根螺钉，使用MTS-858生物力学仪脊柱力学测试平台进行±250N的循环负荷疲劳测试，记录负荷循环中的螺钉位移，计算系统的刚度系数并进行对比分析。

The incidence of junctional kyphosis and its association to the above parameters and to fusion levels were assessed.

Angulation of the hindquarters is in balance with the forequarters; the angle at the hock is relatively sharp, although the Belgian Malinois should not have extreme angulation.

后躯的角度与前躯平衡，飞节的角度比较明显，虽然，比利时玛利诺犬没有太夸张的角度。

Gross observation and mass changes of the grafts: Two weeks after inoculation, there were obvious nod formations at the inoculated sites, but no nod formed in the blank control group.

移植物的大体观察与质量变化：接种2周后，同种异体软骨细胞-FasL组及同种异体软骨细胞组兔接种细胞-材料复合物处，均有明显的结节形成，对照组未形成接节。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
