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。

The earth is a ellipsoid consisted of both solid and liquid, so the true value in each geological time should be less than the calculated oblateness.

地球是个固液混合的椭球体，在各个地质历史时期中地球扁率的真实值应该小于计算的扁率值。

In this paper, the RCS of plate, cylinder and sphere are calculated based on the PO theory.

阐述了用物理光学法解决高频散射的原理，对高频电磁场中的平板、圆柱及球体进行了计算，验证了F -1 1 7A隐身飞机大量使用平板隐身技术的结论。

Department of Energy's Lawrence Livermore National Laboratory, comprises 192 lasers that fire simultaneously at precisely the same point in space: a sphere of fuel two millimeters in diameter.

设在美国能源部Lawrence Livermore国家实验室的国家点火装置，装有192个能够同时向空间同一位置发射的激光器：这个空间是一个直径两毫米的燃料球体。

The general equation of heat transfer in the stationary state is solved for four special forms of bodies, namely, plane, circular cylinder, sphere, and prolate spheroid.

A quasar is an object far away in space that produces bright light and radio waves.

一个恒星状球体是一个远在外太空的能够释放明亮的光和无线电波的物体。

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。
