轴旋转

Theoretically, in spherically symmetric isotropic media, we should not observe rotational signals around the vertical axis before the onset of SH waves.

理论上说，在球对称均匀介质中，在 SH 波到达前不可能观测到绕垂直轴的旋转信号。

Or to have the boat fully loaded with starlight And sing aloud in the splendour of starlight.

轴枢和套圈的表面是准确的旋转表面，并在未施加载荷正确对中。

The axial force and torque of taphole drill are analysed.

通过对开铁口机轴压扭矩的分析和研究，得出了在旋转钻进过程中增加冲打是提高钻进速度的有效手段。

The mixing drum is supported with heavy duty ' trunnion rollers' that rotate by the drive unit.

低能耗。混合筒体由重型的"耳轴滚轮"支撑，通过驱动装置带动旋转。

A rotating arm as an axis, and have a connecting holes, therefore, we connect to the vertical stress analysis of mechanism of connection.

一个旋转臂上既有一个连接轴，又有一个连接孔，因此，我们对竖直连接的连接机构进行受力分析。

For rotation of the workpiece around the vertical axis.

对于周围的垂直轴工件旋转。

When the rotor is high-speed rotating as the pump shaft, the fluid in flow channel forms the pump-up-flow under the influence of the shear and viscous force.

转子随泵轴做高速旋转，流道内的流体在剪力和黏性力的作用下形成"泵送"流。

The piston is attached to the top of a connecting rod by a pin,called a piston pin or wrist pin.the bottom of the connecting rod is attached to the crankshaft.the connecting rod transmits the up-and-down motion of the piston to the crankshaft,which changes it into rotary motion.the connecting rod is mounted on the crankshaft with large bearings called rod bearings.

这个活塞被一个叫活塞销或轴颈销的销子连接在连杆的上部。连杆的底部被连接在曲轴上。连杆把活塞的上下运动传递给曲轴转变成旋转运动。连杆通过一个大的叫做杆轴承的轴承（其实就是滑动轴承，分成两个半圆轴瓦）安装在曲轴上。

We might come up with the idea of rotating the box around the X or Z axis, as in figure 2 above.

我们能找到位于X或Z轴的体附近的旋转思路，如上图2所示。

Around the z axis (but still centered at the same location), then you would need to apply the translation first and then rotate the object.

周围的Z轴（但仍然在同一地点为中心），那么你将需要申请翻译，然后再旋转对象。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
