Length of day ; the earth's rotation ; light pressure from the sun ; angle momentum ; moment of inertia ; angle speed

日长；地球自转；太阳光压；角动量；转动惯量；角速度

It moves them under the Moon, away from the Moon, and to Moonrise and Moonset positions.

因为地球的自转，使的股票和期货的交易每天都通过月亮，它会驱动它们处于月亮之下，远离月亮，月出，和月落的位置。

After 10 to 100 million years of pushing, the neutron star is rotating once every few milliseconds.

经过了几千万到上亿年的加速，中子星开始以几毫秒为周期高速自转。

The undercarriage was a tricycle arrangement, with the wide-track main units retracting inwards into the wing and the nosewheel retracting backwards (following a 90 degree rotation) into the area beneath the cockpit.

飞机起落架是一个类似三轮车布局，配制宽轨的主起落架部分可以向后缩进机翼内，前轮向后回缩（自转90度）进座舱下部的区域。

Her main scientific interests are comparative planetary interiors and rotation, as well as modeling tides and nutation of the Earth, Mars, Mercury and Venus.

她的主要研究专长在于各行星的内部结构和自转的比较。亦精于地球、火星、水星和金星的潮汐作用和地轴的转动的计算。

Post-Newton metric was got inside and outside a uniform uncompressed ideal fluid oblate ellipsoid at rigid rotation.

摘要在后牛顿近似下，得到由均匀不可压缩理想流体在刚体自转下形成的扁球体的内外度规。

The earth is modeled as an oblate and rotating spheroid, and higher order terms in the multiple expansion of gravitational fields are considered. To avoid singularities in computations, the quaternion representation of the spacecraft attitude is used in the angular kinetic model equations.

其中地球被描述为绕短轴自转的椭球体，重力场梯度由四阶Jeffery常数描述，航天飞机的姿态运动用四元素法描述，以避免模型方程中的数值奇异点。

Taking fclio earth rotation and oblateness into consideration, the orbit perturbation, attitude errors and its stability effects on SAR Doppler parameters are analyzed.

在考虑地球自转和扁率的情况下，分析了轨道摄动、卫星姿态指向误差和稳定度对SAR多普勒参数的影响，并进行了数字仿真。

In § 2.3 we study the effects of the oblateness, caused by pulsar rotation, on the pulsar properties, then we calculate the some properties of the pulsar in SN1987A.

即然认为这颗光学脉冲星是老年中子星，要通过吸积加速使它的自转周期减小到现在的0.5毫秒，则表面磁场不能超过2×10〓G。

Earth Rotation is not offhand, it has its own rules.

地球的自转不是随便的而是有一定的规律的。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
