Blazars are one of the most extreme classes of active galactic nucleus, with high luminosity, large amplitude and rapid variability, high and variable polarization, radio core-dominance, and apparent superluminal speeds. Their broad band emission extends from radio up to gamma-ray band, and is dominated by non-thermal process.

中文摘要：在AGNs中，Blazar天体是具有极端性质的一类，它以大幅快速光变、高且变化的偏振、射电核主导、视超光速运动、全波段非热辐射为主要特征。

The term planetary nebula , used to describe this general class of objects , is misleading .

Know astronomical unit and light year are used for expressing the distance between celestial bodies.

知道天文单位和光年是用来丈量天体之间距离的单位。

The magnitude, abbreviated as mag , is an astronomical unit describing the brightness of a celestial object.

Astrobiology's goal is to make sure that does not happen.

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.
