您要查找的是不是：
- They spend most of the time in a stable state with the magnetic field aligned roughly with the spin axis. 他们与大致和旋转轴排列在一起的磁场一起，在其存在的大部分时间里都处于稳定状态。
- Lack of orthogonality between a suspension(or centering)axis and the spin axis will then result in a drift-producing torque exerted on the gimbal. 悬挂轴和自转轴间的不垂直度将引起产生漂移作用在框架上的力矩。
- The tilt of the planet's spin axis oscillates by as much as 20 degrees over a period of 125,000 years. 火星自转轴的倾角，以12万5000年为周期，变化达到20度。
- The idea behind the experiment is simple: Put a spinning gyroscope into orbit around the Earth, with the spin axis pointed toward some distant star as a fixed reference point. 实验背后的原理十分简单:将转动的回转仪放在环绕地球的轨道,转轴指向远处星体,作为固定基准点。
- The orientation of the equatorial belt suggests the parent star maintained the same spin axis both before and after it exploded. 环赤道带的方向说白，前身星在爆发前后的自转轴取向保持不变。
- Lack of orthogonality between a suspension(or centering) axis and the spin axis will then result in a drift-producing torque exerted on the gimbal. 悬挂轴和自转轴间的不垂直度将引起产生漂移作用在框架上的力矩。
- The narrow, jet-like feature running from north to south in the image is likely parallel to the spin axis of the pulsar. 自北向南贯穿图象的狭窄喷流结构可能与脉冲星的自转轴重合。
- A small differential radius of gyration will have less separation and sometimes produce one thick oil band around the ball, due to the lack of a significant preferred spin axis. 大RG差(HighRGDifferential)的球，会造成油线与油线间的较大间距，相反的，小RG差(LowRGDifferential)的球，所产生的油线间距也会较小，甚至有可能只会产生一条很宽的”油带”而已。
- In the 1980s geologists used the assumption of hotspot fixity to reconstruct plate motions and pinpoint the past locations of the earth with respect to its spin axis. 1980年代，地质学家利用热点固定的假设，重建板块运动并且标出过去地球相对于自转轴的位置。
- A compass with a motorized gyroscope whose angular momentum interacts with the force produced by the earth's rotation to maintain a north-south orientation of the gyroscopic spin axis, thereby providing a stable directional reference. 陀螺罗经一种装有机动陀螺仪的罗盘，由于陀螺仪的角动量与地球的自转产生的力相互作用，使陀螺转轴一直保持南北方向，从而提供一个稳定的方向指示
- The motorcycles were spinning along at full speed. 摩托车正全速疾驰。
- The heavy ax was awkward to use. 这把重斧头不好用。
- The lorry went into a spin on a patch of ice. 卡车在一片冰地上打滑了。
- Let's go for a spin in my new car. 坐我的新汽车兜一圈吧。
- The car is spinning along120 li per hour. 这车正以每小时120里的速度行进。
- The axis of a circle is its diameter. 圆的轴线是其直径。
- The firemen splintered the door with an ax. 消防队员们用斧头将门砸开。
- Does the earth rotate on an axis? 地球是绕轴旋转的吗？
- I've been in a real spin all morning. 我整个上午都晕头转向的。
- A wheel revolves round/on its axis. 轮子是绕轴旋转的。
