自转

This should cover a very wide scope from such aspects as the effect of the rotation of the earth and planetary and galactic effects, major theories of development of the earth, lineaments, interpretation of earthquake data, major times of tectonic and biological change, and so on.

这应当覆盖非常广阔方面的范围，如同地球的自转、行星与银河系运动的作用，有关地球及其面部轮廓发展的主要理论，对于地震数据的解释，板块运动与生物变化的重要时段，等等。

He was a gyrocopter enthusiast before his microlight aircraft crash.

在他微型飞机出事之前，他热衷于飞自转旋翼机

Not only is the Earth's rotation too weak to affect the direction of water flowing in a drain, tests you can easily perform in a few washrooms will show that water whirlpools both ways depending on the sink's structure, not the hemisphere.

其实，地球自转的作用很微弱，因此难以影响水流动的方向。你可以在一些盥洗室中轻易地验证这一点，无论是逆时针还是顺时针，水流旋涡的方向取决于水槽的结构，而非南北半球。

The second-order post-Newtonian(2PX) equations of light ray have to be discussed under the recent extension of the DSX scheme which was founded in early 1990's to discuss a complete first-order post-Newtonian celestial mechanics for N arbitrarily composed and shaped, rotating deformable bodies.

DSX体系是在20世纪90年代初建立的，用来讨论对N个任意形状和组成、自转可变形物体的一套完整的一阶后牛顿(1PN)天体力学理论。

The earth , in revolving around thesun ,also t urns on it s own axis.

例 2 地球在围绕太阳运行的同时也绕轴自转。

Astronomical yearbooks and calendars for amateur astronomers provide the times of the beginning of the synodic solar rotations as well as the longitudes Lo.

天文年历和日历为业余天文学家提供了太阳会合自转周期的始时和经度Lo。

From orbit, though, its cities and factories and spaceports could be seen as the planet's rota tion brought its cavernous sinkholes one at a time into view.

不过，在轨道上望去，这颗星球上的城市、工厂和太空港就会随着星球的自转而逐一在坑坑洼洼的溶洞中显现。

If accretion takes place in eccentric orbits as well, the rotation will be prograde and of the right order of magnitude

如果吸积发生在偏心轨道，则自转将是正向的，且快慢也合适。

The authors find coupling mechanism of momentum of nutations between solar and earth. It is caused by solar radiation, earth's rotation and revolution, angle between ecliptic and equator, irregularity of oceans and continents between northen hemisphere and southen hemisphere and layer structure of earth's core.

作者发现：太阳辐射，地球自转与公转，黄、赤交角的存在，陆地和海洋在地球表面南、北半球的不规则、不对称地理分布，及地球内部因〖ZZ〗形成的分层结构，构成了一套天然的能使地球产生自由章动的日、地间动量相耦合的物理机制。

Magnetism is, ultimately, the result of a quantum-mechanical property known as spin.

最终，磁性产生于由自转的量子力学特性（quantum-mechanical property）。

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。
