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 point on the celestial sphere that is directly above the observer.

天顶：在观测者正上方的天体上的一点

Oh, Lord God almighty, may there be peace in celestial regions.

哦，上帝万能的，可能有和平的天体地区。

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.

中美掩星观测计画的目标为测量彗星核大小至几公里的古柏带天体之数量与大小分布。

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。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
