| 1. | Energy is injected into space by quasars in the form of fast, nonrelativistic particles .
能量是以快速非相对论性粒子的形式由类星体注入空间的。 |
| 2. | The quasars cannot shine for longer than a few million years with their present luminosity .
在几百万年以后，类星体将不可能具有他们今天那样的发光度。 |
| 3. | The quasars are so bright that they probably are consuming their energy resources at a very rapid rate .
类星体非常明亮，因而它们可能正在极其迅速地消耗它们的能源。 |
| 4. | The redshift means that the quasars are very far away, more distant than the most distant galaxies we can see .
红移意味着类星体是非常非常遥远的天体，比我们观测到的最遥远的星体还要远。 |
| 5. | This explains why there are no nearby quasars
这解释了为什么附近没有类星体。 |
| 6. | Quasar is short for quasi - stellar radio source
类星体是“类似恒星射电源”的缩写。 |
| 7. | Vacuum phase - transition and the energy mechanism of quasars
真空相变与类星体的能源机制 |
| 8. | Multi - wavelength observation of quasars
类星体的多波段观测 |
| 9. | Many quasars radiate as much power as 100 trillion suns
许多类星体辐射的功率就如100兆个太阳那般强。 |
| 10. | A radio galaxy is related to , but appears larger than , a quasar
一个射电星系与之有关，但是它比类星体要大。 |
