自转

This is the time of rotation stoppage.

这就是地球自转停止的时间。

Its rotation, or its day, is only about 10 hours long.

它的自转，或它的一天只有大约10个小时。

All I'm saying is, the moon did not have a rotational cycle of 14 hours.

我要说的是，月球可没有14小时的自转周期。

With the advancement of technology, people's growing demand for the bar, its accuracy is also getting higher and higher, before people parallel roller leveler straightening tubes, rods and other circular cross-section of the build, round-wood in hand Direct the process of rotation is easy to produce, and only straightening roundwood roll axis perpendicular to the longitudinal section on the bend.

随着科技的进步，人们对棒材的需求量越来越大、对其精度要求也越来越高，以前人们采用平行辊矫直机矫直管、棒等圆形断面条材，圆材在矫直过程中容易产生自转现象，并且只能矫直圆材垂直于辊轴的纵向剖面上的弯曲。

Therefore we will benefit of most of the geometric mathematical concepts to deal with our colors, such as norms, scalar product, projection, rotation or distance.

所以我们将有益于大多几何数学概念应付我们的颜色，例如准则、数积、投射、自转或者距离。

For example, since the earth to the base, relative to the sun to measure time to get the sun when the time is measured relative to the stars, known as the sidereal time, to atomic transition frequency as a benchmark time for the system is called atomic time.

例如，以地球自转为基准，相对于太阳来计量时间得到的是太阳时，相对于恒星来计量时间，称为恒星时，以原子的跃迁频率为基准的时间系统称为原子时。

"The third planet from the sun, having a sidereal period of revolution about the sun of 365.26 days at a mean distance of approximately 149 million kilometers (92.96 million miles), an axial rotation period of 23 hours 56.07 minutes, an average radius of 6,374 kilometers (3,959 miles), and a mass of approximately 29.11 10 kilogram s (13.17 10 pounds)."

"离太阳第三远的行星，绕太阳转动的恒星周期为365.26天，平均距离大约是1.49亿平方公里(9，296万英里)，自转一周的周期为23小时56.07分，平均半径为6，374公里(3，959英里)，质量大约是29.11×10千克(13.17×10英镑)。"

The Earth moves around the sun and spins on its slanting axis at the same time.

地球在绕着倾斜地轴自转的同时也是绕着太阳分转。

The snag is that the rotation of the Earth is not so reliable.

不便之处是地球的自转并不是那样的准确可靠。

Christchurch's international chart-topping songstress Hayley Westenra may be only 20, but her biography is in the shops today.

新西兰燿居榜单首位的国际明星海莉·薇思特拉虽然只有20嵗，但是她的自转今天已经出现在了书店里。

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。
