您要查找的是不是：
- Axis Of Rotation: vector expressed in a given referential. ：给定参数的向量来定义轴向。
- The horizontal axis of a two-dimensional Cartesian coordinate system. 横坐标轴平面直角坐标系中的水平横轴
- The vertical axis of the chart represents the value of the series, and the horizontal axis represents time. 图表的竖轴表示时序值,横轴表示时间。
- Locations on the earth's surface are specified in terms of the earth's axis of rotation. 地面的定位是沿着地球的自转轴而定的。
- Indicated ISO sensitivity is on the horizontal axis of this graph, standard deviation of luminosity is on the vertical axis. 表明，国际标准化组织的灵敏度是对横轴这个图，标准偏差的亮度是对纵轴。
- Structure passed by reference, that identifies axis of rotation of the quaternion. 结构,标识该四元数的旋转轴。
- Like Earth, the axis of rotation tilts 24. Hence, there are seasonal changes in Mars. 火星的自转倾角为24,和地球差不多,所以火星亦有四季变化。
- A similar great circle drawn on the surface of a celestial body at right angles to the axis of rotation. 天球赤道在天体表面与自转轴成直角的大圆
- The shoulder is another axis of rotation, and this axis is used in computing Shoulder Pull. 由于我们还借助肩膀的力量把球往上拉,肩部可以看成是第二个转动轴。
- Because the core current is somewhat symmetrical around the axis of rotation, the associated magnetic field is similar to that of a bar magnet. 因为地核流在旋转轴周围存在着一些对称，所以相关的磁场与棒磁铁的磁场相似。
- Magnetar's rotation axis of rotation around the second 60 weeks, it is super star after the explosion residues. 磁星每秒钟围绕旋转轴自转60周，它是超级大恒星发生爆炸后的残留物。
- We hold up our left hand and point our thumb in the positive direction of the axis of rotation. 我们握住自己的左手并且将自己的右手拇指朝向正旋转轴方向。
- The Geographic South Pole is where Earth's axis of rotation intersects its surface. 地理上的南极点是地球自转轴线与表面的交差处。
- Because the core current is somewhat symmetrical around the axis of rotation,the associated magnetic field is similar to that of a bar magnet. 因为地核流在旋转轴周围存在着一些对称，所以相关的磁场与棒磁铁的磁场相似。
- Moment of inertia: turning around its axis of symmetry, object has the character keeping speed and the direction of the axis of rotation not changing. 转动惯性:物体在绕着自己的对称轴转动时,具有保持转速和转动轴方向不变的性质。
- The horizontal axis shows sales in millions of dollars. 横轴表示以百万为单位的销售额。
- Taper support rib usually two or three cam roller contacts, in order to edge into the axis of rotation to be sent to the uniform output shaft. 锥度支撑肋通常与两个或三个凸轮滚子接触，以便入力轴的旋转可均匀地传送到出力轴。
- Pole shifts are a cataclysmic inversion of the planet's axis of rotation, up to180 degrees; a sudden slippage of the planet's solid crust around the molten core. 磁极转换是行星旋转轴的大变动倒置，等于180度翻转；在熔化的地核周围行星固体外壳突然意外的滑移。
- Dynamic equilibrium: if the axis of rotation of the rigid body is the principle axis of inertia, the additional dynamic reaction force of the bearing is zero. 静平衡：刚体转轴过质心，则刚体在仅受重力而不受其它主动力时，不论位置如何，总能平衡。
- Birds and compasses know north from south because, like a giant bar magnet, the earth's magnetic field has two poles that line up closely with the planet's axis of rotation. 候鸟与指北针都知道何为北方、何为南方，因为地球就像一条巨型磁铁棒，它的磁场有两极，且这两个地磁的磁场线和地球的自转轴非常接近。
