  1. They have discovered now, previously unimagined objects-pulsars, quasars, and black holes.

    他們發現了以往想象不到的新客脈沖類星體和黑洞。
  2. The quasars cannot shine for longer than a few million years with their present luminosity.

  3. A lunar occultation of a quasar

    類星體的月掩測定
  4. We form a ly a line sample from spectra of 19 qsos in the literature. in this analysis, we demonstrate that a proximity effect is present in the data ; i. e., there exists a significant deficit of lines at zabs = zem, within 4h - 1 mpc of the qso emission redshift. and the deficit depends on the rest equivalent width of the lines, with weak lines showing a relatively weaker effect

    我們發現所選樣本中確實存在接近效應,特別在z _ ( abs ) z _ ( em )附近距類星體4h ~ ( - 1 ) mpc范圍內, ly森林的線數相對演化規律估計得到的線數缺少很顯著,並且與譜線的靜止等值寬度有關,弱線的接近效應較弱。
  5. Energy is injected into space by quasars in the form of fast, nonrelativistic particles.

    能量是以快速非相對論性粒子的形式由類星體注入空間的。
  6. The quasars are so bright that they probably are consuming their energy resources at a very rapid rate.

    類星體非常明亮,因而它們可能正在極其迅速地消耗它們的能源。
  7. The redshift means that the quasars are very far away, more distant than the most distant galaxies we can see.

    紅移意味著類星體是非常非常遙遠的天,比我們觀測到的最遙遠的還要遠。
  8. This explains why there are no nearby quasars

    這解釋了為什麼附近沒有類星體
  9. Quasar is short for quasi - stellar radio source

    類星體是「似恆射電源」的縮寫。
  10. Vacuum phase - transition and the energy mechanism of quasars

    真空相變與類星體的能源機制
  11. Multi - wavelength observation of quasars

    類星體的多波段觀測
  12. Many quasars radiate as much power as 100 trillion suns

    許多類星體輻射的功率就如100兆個太陽那般強。
  13. A radio galaxy is related to, but appears larger than, a quasar

    一個射電系與之有關,但是它比類星體要大。
  14. Two also lie near very dense clusters of massive young stars, intimating that sgrs tend to form from such stars

    其中兩顆還與由大質量的年輕恆所組成的緻密團距離很近,這表示sgr可能是由這類星體所演化而來的。
  15. Some speculation exists that quasars are actually white holes instead of supermassive black holes

    一些人推測存在的類星體實際上是白洞而不是超大質量的黑洞。
  16. Other speculations include the hypothesis that quasars are actually white holes instead of supermassive black holes

    其它的推測包括類星體實際上是白洞而不是超大質量黑洞的假設。
  17. Candidates for more massive black holes were first provided by the active galactic nuclei and quasars, discovered by radioastronomers in the 1960s

    活躍的銀河核和類星體首先提供了更多質量龐大的黑洞候選者,在1960年無線天文學家發現了它們。
  18. Core - dominated quasar

    核占優類星體
  19. Because some brighten or dim significantly in less than a day, their energy - producing regions must be no larger than the distance light can travel in a day ? about the size of our solar system

    由於某些類星體在不到一天的時間里明顯增亮或變暗,其產能區應該不會比光一天行進的距離長,即約為我們太陽系的大小。
  20. The project is now approaching the halfway point in its goal of measuring one million galaxy and quasar redshifts

    這個計畫的目標是量取100萬個系與類星體的紅移,現在已將達成目標的一半。
