彗星的

The article said that Herschel had developed a "new theory of cometary phenomena"; he had discovered planets in other star systems; and he had "solved or corrected nearly every leading problem of mathematical astronomy ."

文章说赫舍尔已经发展了"彗星现象的新理论"，发现了其他星系的星球，而且他已经"解决并更正了几乎每个数理天文学的主要问题"。

The second option is to extract the track directly from the aerogel in a "keystone", using an extraction technique that we developed here at Berkeley specifically for Stardust and have been using successfully for several months on the cometary collector.

第二种方案是直接从气凝胶中提取出含有轨迹的楔形块，用的是我们在伯克利特别为 Stardust 开发并在数月前成功用在彗星收集器上的提取技术。

Arcing toward a fiery fate, this Sungrazer comet was recorded by the SOHO spacecraft's Large Angle Spectrometric COronagraph on 1996 Dec.

以优美的弧线走向了惨烈的毁灭之路，这颗掠日彗星由SOHO探测飞船的广角光谱日冕观测仪于1996年12月23日记录得到。

The Crab Nebula is cataloged as M1, the first object on Charles Messier's famous list of things which are not comets.

蟹狀星雲的編錄是M1，也就是梅西葉著名的「非彗星型錄」的第一個天體。

"The filamentary appearance of P/2010 A2 is different from anything seen in Hubble images of normal comets, consistent with the action of a different process," Jewitt says.

"根据后续观测到的一系列异状都表明了 P/2010 A2的纤维构造不同于哈勃望远镜以往观测到的普通彗星，" Jewitt 说。

David: Yeah, shortly after Space Invaders, at least for me, there was then quite a proliferation, Pac Man was probably the most obvious, Asteroids, Galaxian, and, you know, you'd go to any fish 'n' chips shop and there would be an arcade cabinet.

大卫：是的，就在太空入侵者出现之后不久--至少对我来说不久后，就出现了许许多多类似的游戏，小精灵可能就是其中最引人注目的游戏了，另外还有爆破彗星，小蜜蜂等等--当时每个卖薯条的店里都放着一台大型游戏机。

But this time her target wasn't a simple lunar eclipse or darting comet.

但是这次，她的目标却不是简单的月蚀，也不是飞驰的彗星。

In the solar system are a large number of small meteoroids, and some groups of the meteoroid is, the meteor is the product of the collapse of the comet.

太阳系中还有数量众多的大小流星体，有些流星体是成群的，这些流星群是彗星瓦解的产物。

Astronomy software, shows you the complete night sky (340,000 stars) and our solar system in a 3D orrery view with the planets, asteroids, and comets from any place at any time.

天文学软件，向您显示完整的夜空（ 340000颗星）和我们的太阳系在一个三维orrery的看法与行星，小行星，彗星，从任何地方在任何时候。

Methods: Human leukemia cell line K562 was treated with different concentrations of WM. The proliferation of K562 cells was examined by MTT assay. DNA damage in K562 cells was examined by single cell gel electrophoresis assay, and apoptosis of K562 cells was detected by Annexin V-FITC/PI double staining. The expressions of total Akt, phosphorate Akt, and NF-κB p65 mRNA and protein were detected by RT-PCR and Western blotting, respectively.

以不同浓度的渥曼青霉素作用于人类髓细胞白血病细胞K562，采用MTT法检测细胞增殖活性，单细胞凝胶电泳技术检测细胞DNA损伤形成的"彗星"样拖尾现象，Annexin V FITC/PI双标法检测细胞凋亡，Western blotting、RT-PCR检测渥曼青霉素作用K562细胞后总Akt和磷酸化Akt以及NF-κB基因及蛋白表达水平的变化。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
