天体的

Celestial mechanics enables astronomers to calculate the positions of the planets at any time in the post or future and to predict the movements of comets.

天体力学使文学家能计算出行星在过去或将来任何时候的位置，并能预报彗星的运行位置。

See [90]. The theoretical work by these mathematicians supplied many of the ideas and approaches that were later used in more applied situations in physics, celestial mechanics, chemistry, biology, and other fields.

这些数学家的理论工作提供了很多思想和方法，这些后来都被应用于物理、天体力学、化学、生物学和其它领域更为复杂的情形。

Furthermore the laws of celestial mechanics www.readinggroupguides.com/ credited to Copernicus, Kepler and Galileo were know by the Chinese and used to create a very accurate calender in 1280 for Kublai Khan (page 23 -28) that was later adopted by the Europeans.

此外天体力学定律 www.readinggroupguides.com/贷记哥白尼，开普勒和伽利略系统是由中国的了解和用于创建一个非常准确的在1280年忽必烈汗（页日历23 -28），后来由欧洲人通过。

The goal of TAOS project is measuring the number and size distribution of Kuiper Belt Objects down to a few kilometer size of cometary nuclei.

Some objects in deep space are not quite as they appear.

宇宙中的一些深空天体看起来并不是它们真实的样子。

Preliminary orbital computations by the Minor Planet Center suggested an atmospheric entry of this object within a day of discovery.

作为国际小行星中心所在地的哈佛史密松天体物理中心昨天表示，北京时间今天上午10：46，小行星2008 TC3与地球相撞的概率可达99.8%-100

With a mass of only 2.5 Jupiters, the object is too small to be a star or brown dwarf and must instead be a planet.

因为它的重量仅有木星的2.5 倍，所以该天体不足以成为一颗恒星或褐矮星，由此它一定是一颗行星。

Comparing with the magnetic fields in the neutron star andwhite dwarf of 10~7 Gauss, the magnetic fields in the solar atmosphere is much smaller.

与中子星、白矮星等致密天体上高达10~7高斯的磁场相比，太阳表层大气中的磁场则要弱得多。

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.
