Facet joints oriented parallel to the sagittal plane provide substantial resistance to axial rotation but minimal resistance to shearing forces, whereas joints oriented more in a coronal plane tend to protect against flexion and shearing forces but provide minimal protection against rotation fig.

小关节朝向趋于矢状位可以限制脊柱的轴向旋转但是减少了对剪应力的限制。而趋于水平的小关节可以更好的保护屈曲和剪切下的应力，但对旋转的抵抗力降低（图3）。

Two cylinders drive the tipping unit, loading the bars; one asynchronous motor drives chain motion mechanism, implementing the feed and back off movement of bars; bar lifting movement in the process of chamfering and blanking movement after machining are carried out by another two cylinders; one asynchronous motor rotates the bar and one cylinder swings the wheel head when grinding; the feeding of the wheel head is accomp...

它通过控制两套汽缸驱动翻爪完成上料，一台异步电动机驱动链条式多轮运动机构完成磨削前的进料和磨削后的退料，两套汽缸完成磨削倒角加工时的预料和加工完成后的落料，一台异步电机在磨削加工时驱动棒料旋转，一个汽缸驱动磨头在加工时摆动，一台步进电机驱动磨头实现磨削进给，两套汽缸驱动翻爪完成下料，而磨头是用一台异步电机驱动砂轮旋转的机构，并给出了控制系统原理图及程序流程图，解决了控制器输入点数相对不足的技术问题。

Or, rather, it employs two ring-shaped half-pipes that rotate with respect to one another (the lower one remaining fixed while the upper one revolves along with the building). The joints between the half-pipes have rubber seals to stop the contents leaking, and each half-pipe has a vertical pipe connected to it, to introduce or dispose of the fluid concerned.

或者更确切的说，它使用了两根彼此旋转的环形半管（当上面那根独自围着建筑旋转的时候，下面那根余下的部分被固定），两根半管的接头有橡胶防止泄漏，每根半管都有一根垂直管与之相连，引入或排出附着的液体。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
