联轴器是一种联接两根相邻轴末端的装置。
A coupling is a device for connecting the ends of adjacent shafts.
机械构件中，联轴器可以用来实现相邻两根旋转轴的半永久性联接。
In machine construction, couplings are used to effect a semipermanent connection between adjacent rotating shafts.
他们建议，如果术者希望将上位相邻节段的多裂肌束去神经化降至最低，应利用经皮技术在头侧节段置入椎弓根螺钉。
They recommended that pedicle screw insertion at the cephalad level be performed percutaneously if one desires to minimize denervation of the multifidus complex at the cephalad adjacent level.
因此，在一个节段经乳突置入椎弓根螺钉可引起支配相邻关节突关节头侧水平结构的后内侧支损伤。
As a result, insertion of a pedicle screw through the mammillary process at one level can cause injury to the medial branch of the dorsal rami that supplies the adjacent cephalad level.
目的：观察不同骨水泥对椎弓根螺钉的加固作用及其对相邻脊髓的影响。
Objective: to observe the ability of different bone cements to augment pedicle screw fixation and the effect of the cements on the adjacent spinal cord.
编队内各导弹采用相邻局部通信，编队之间则通过各编队通信拓扑生成树的根节点进行通信。
The missiles within a group communicate by means of the nearest-neighbor topology, while communication between groups is implemented through the root nodes of the group topology spanning tree.
