您要查找的是不是:
- main spin axis 主自旋轴
- 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 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 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。
- Next to or facing the main stem or axis. 近茎轴一侧的紧挨着主茎或轴的,面向主茎或轴的
- The main impediment to growth is a lack of capital. 影响发展的主要障碍是缺乏资本。
- Crowds thronged the main square of the city. 城里的大广场上挤满了人群。
