自转

This is because as Earth turns, air is pulled to the right in the northern hemisphere.

这是因为地球自转，空气被北半球右侧。

The Prime Meridian, which runs through Greenwich in south-east London, became the basis for the world's time keeping in 1884 after the first Astronomer Royal, John Flamstead, calculated that the Earth rotated on its axis once every 24 hours.

1884年，首位皇家天文学家约翰法兰姆斯坦算出地球每隔24小时绕轴自转1次，使得通过伦敦东南格林威治的本初子午线成为全球计时基准。

A GSO satellite appears stationary above the earth, because of its running direction and orbital velocity is as same as the earth's rotational direction and speed respectively.

由于静止的运转方向和角速度与地球的自转方向和角速度相同，卫星的空间位置与地面任意地点的相对空间关系固定不变。

The theoretical and experimental investigations of discus flight indicate the following useful conclusions:the optimum combination of throw angle and discus inclination angle is 35°/26°at zero wind,while 45°is not the best release angle due to the aerodynamic force;different combinations of throw angle and inclination angl...

由于气动力的作用，45°并非铁饼的最佳投掷角度，实验和理论研究表明：无风时35°/26°的投掷角/倾角组合最佳；顺风和逆风投掷必须采用不同的投掷角/倾角组合才能获得当地条件下的最好成绩；铁饼出手时25r/s的自转速度已经可以满足稳定性的要求。

Time is now set not by earth's rotation, but by satellite and atomic clock.

现在是时间设定不是由地球自转的，而是由人造卫星和原子钟。

Time is now set not by earth's rotation, but by satellite and atomic clock.

现在，时间不再以地球的自转来设定，而是使用卫星和原子钟来确定。

Time is now set not by earth's rotation, but by satellite and atomic clock.

但现在时间并不是依据地球自转来决定，而是由卫星和原子时计决定。

Jerry Lee Lewis wasn't completely off the mark when he sang about Chantilly Lace,"a wiggle in her walk and a giggle in her talk make the world go 'round."

歌手杰里李刘易斯并没完全说明出来，但却唱出Chantilly Lace的歌：扭腰摆臀的走动与花痴般的傻笑让世界因她而自转。

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。
