彗星

Sekanina, who has studied how Comet Shoemaker-Levy 9 and others have split apart, has concluded that the events that create these multiple nuclei often occur far from the Sun, even around aphelion.

Sekanina曾经研究过Shoemaker-Levy 9 彗星（1994年撞击木星的彗星——译者注）和其它彗星是如何分裂的。他得出结论，产生这些多重彗核的事件经常发生在远离太阳处，甚至可以是远日点。

Your comet is going to collide with the Earth and every living thing in its path will be killed!

你的彗星将会于地球相撞，彗星将会摧毁它撞到的地方的每一个生物。

It was a comet,andMaria had been the first person to see it and to report on it.

那是一颗彗星，而玛丽亚就是观测到这颗彗星并且报导它的情况的第一个人。

Of or relating to or resembling a comet .

属于或关于彗星的；类似于彗星的。

Locked within the cometary particles is unique chemical and physical information that could be the record of the formation of the planets and the materials from which they were made, he adds.

彗星微粒中封存着独特的化学和物理信息，或许可以记录行星和和彗星成分物质的形成，他补充说。

Less than a year after arriving on Earth the Stardust cometary samples have both challenged and confirmed scientists' most basic assumptions on the nature of comets, the history of the solar system, and the origins of life on Earth.

在"星尘"号彗星样品回到地球后不到一年的时间里，便对科学家们关于彗星本质、太阳系历史和地球生命起源的最基本的假设提出了挑战或肯定。

The Centre will continue in the pioneering traditions of astrobiology on panspermia, interstellar and cometary dust, meteorites from Mars, the connection between comets and terrestrial life, and comet-Earth interactions so on.

中心将继续在太空生物学方面的研究，包括胚种学，星际和彗星尘埃，火星陨石，彗星和陆地生物间的联系，彗星与地球间的关系等。

During the time he searched for comets, especially in the early and middle periods, Zhou found 20 comets independently and observed many known comets, despite having little access to comet ephemerides (A'lashankou, Bole is a remote place where transportation and communication are difficult). On 1985 Oct. 17, he independently discovered the comet C/1985 R1, and this achievement was honored by the Purple Mountain Observatory as the first Chinese amateur finding since the founding of the People's Republic of China.

这期间，特别是在他的寻彗早、中期，在没有任何有关彗星信息的情况下（阿拉山口，博乐是个交通，通讯不畅的地方），周兴明先生独立找到20颗彗星和观测了许多已知的彗星。1985年10月17日他独立找到的彗星C/19851(C/1985R1， Comet Hartley-Good)被我国紫金山天文台的专家誉为&新中国成立后的第一个业余发现&。

Three new groups of near-Sun comets have since been identified, two of them by German amateurs. In January 2002, Maik Meyer - who manages the Catalogue of Comet Discoveries Web site ( http://www.comethunter.de/) and has found 37 SOHO comets - noted that a newly discovered non-Kreutz SOHO comet and one found four years earlier had similar orbits.

自从SOHO上天后，又有3个新的族被发现，其中两个是由德国的业余爱好者发现的。2002年1月，发现了37颗彗星的德国爱好者Maik Meyer （他的彗星发现网站是 http：//www.comethunter.de/注意到，一颗心发现的非Kreutz族彗星和4年前发现的一颗有着相似的轨道。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
