星系

Much progress has been made in locating Earthlike planets but about 1,000 star systems have also been subject to serious radio scrutiny.

这项工程的很多进展是通过锁定像地球一样的行星来确立的，但是只有大约一千个星系受到严密的观察。

To study the star formation properties of galaxies is one of the major tasks of extragalactic astronomy.

星系的恒星形成性质的研究是目前河外天体物理学的热门研究领域。

Some of its brighter stars have been used as standard candles to establish important estimates of extragalactic distances and the scale of the Universe.

一些它的较明亮的恒星发出的光已经被用作标准光谱分析去建立银河系外星系距离的重要估算和宇宙的度量。

"Extragalactic nebula" is a former name for "galaxy".

&外星云&是&星系&的曾用名。

This galaxy was observed by a team affiliated with the HST Key Project on the Extragalactic Distance Scale.

星系NGC 4603由隶属于哈勃太空望远镜重大项目组的外银河系量天尺工程团队观测。

The luminosity of the most of extraglactic H2O megamaser sources is between tens and hundreds L ⊙, but one of the extragalactic H2O megamaser source TXFS 2226-184 is 6100 L ⊙. It belongs to the class of radio galaxy and is not general. It is mainly caused by its wide spectral profile.

多数河外H2O超脉泽源的光度在几十至几百个 L ⊙之内，但TXFS2226－184源的河外H2O超脉泽源的光度达6100 L ⊙，它属于射电星系类型，是主要由于其谱线轮廓较宽所造成的一种例外情况。

Since the first extragalactic H2O megamaser source toward the Active Galactic Nuclei NGC 4945 was discovered, 19 sources have been found.

自从在活动星系核NGC 4945的视线方向上发现第一个河外H2O超脉泽源以来，迄今为止已发现了19个河外H2O超脉泽源。

There are occasional exceptions if the leaders are handicapped minority, feministic atheist dwarfs, who also happen to be illegal aliens from ANY country or galaxy as long as they are democrats.

当然也有偶尔例外的时候，假如这个领导人是一个少数民族的残疾人，主张男女平等的无神论者，还是侏儒，恰好还是从外国或者外星系来的非法居民，而且还是民主党人。

Geminid meteors are named for the constellation Gemini the Twins.

双子座流星雨的名字来源于双子星系。

Six months later, Ulic and Aleema were joint warlords of the Empress Teta system. Their claim to that system was challenged by the upstart nomad, Mandalore. The two entered into a personal duel on Kuar.

六个月后，乌立克和阿力玛联合黛塔女皇星系的军阀，对抗前来挑战主权的傲慢游牧民族领导人曼道罗。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
