有人可以幫我翻譯這段天文資料嗎20點^^

1. WHY STUDY JETS?

Relativistic jets are a striking manifestation of

the efficient energy release from matter accreted

onto compact objects observed from X-ray binaries

and active galactic nuclei (AGN). The mechanisms

of jet formation and propagation remain

mysterious and new observations will be needed

to understand them. The evolution time scales

for jets produced by X-ray binaries with stellarmass

compact objects is millions of times faster

than for AGN jets. Observations of jets from Xray

binaries hold great promise for revealing jet

dynamics.

The first discovery of jets from Galactic X-ray

binaries was of stationary, large-scale lobes in the

X-rays [1] and radio ([2] for a review). Closer

in, near the compact object, jets take on two distinct

incarnations. One is compact jets found in

the hard X-ray spectral states. The compact jets

tend to be steady, at least to the sensitivity of current

observations, and, as the name would imply,

compact, with angular sizes of tens of milliarcseconds.

The other incarnation of jets from Galactic

black hole candidates are large scale jets. Such

jets are formed in high mass accretion rate states

often, and perhaps always, at state transitions.

Often these jets are impulsive events where dis-tinct

blobs from individual injection events can be

resolved and their motion can be measured. We

will concentrate on this class of jet in this review.

    1. WHY STUDY JETS?

    為何要研究噴出?

    Relativistic jets are a striking manifestation of the efficient energy release from matter accreted onto compact objects observed from X-ray binaries

    and active galactic nuclei (AGN).

    相對論所說的噴出是一種能量撞擊的證明,從成長中的物(星)體釋放出來的能量,碰到X光雙子星周邊的緊實物體或活動星核(AGN).

    The mechanisms of jet formation and propagation remain mysterious and new observations will be needed to understand them.

    噴出的物理現象及傳遞過程仍然保持神秘,為了解噴出,需要新的觀察報告.

    The evolution time scales for jets produced by X-ray binaries with stellarmass compact objects is millions of times faster than for AGN jets.

    用雙子星X光與星群緊實物來測量噴出的時間,比AGN快了幾百萬倍.

    Observations of jets from Xray binaries hold great promise for revealing jet dynamics.

    以雙子星X光法的觀察報告非常有可能揭開噴出的動力狀態.

    The first discovery of jets from Galactic X-ray binaries was of stationary, large-scale lobes in the X-rays [1] and radio ([2] for a review).

    雙子星X光法對噴出的第一個發現是,越大的列片的X光與無線電波越強,這是守衡的.

    Closer in, near the compact object, jets take on two distinct incarnations.

    更貼近些,接近緊實物核心,噴出有兩種典型.

    One is compact jets found in the hard X-ray spectral states.

    一種緊實噴出可在硬核X光光譜中發現

    The compact jets tend to be steady, at least to the sensitivity of current observations, and, as the name would imply,compact, with angular sizes of tens of milliarcseconds.

    這種緊實噴出傾向於安定,至少目前所觀察到的是如此,並且,望文生義,緊實意味著噴出體積微小至少維持數十宇宙秒.

    The other incarnation of jets from Galactic black hole candidates are large scale jets.

    另一種噴出的典型,是來自宇宙黑洞的大傢伙.

    Such jets are formed in high mass accretion rate states often, and perhaps always, at state transitions.

    這種噴出,經常甚至總是是在巨大星群中形成,在星群型態轉變時出現.

    Often these jets are impulsive events where distinct blobs from individual injection events can be resolved and their motion can be measured.

    通常,這些噴出是因為不同的星團所激發出來的.我們可以確切的觀察測量到,這些星團來自不同的運行軌道.

    We will concentrate on this class of jet in this review.

    在這篇評論中,我們將持續關注這類型的噴出.

    1. 為什麼研究噴氣機? 相對論性的噴氣機是高效率的能量發行的醒目的顯示從問題共同生長了緊湊對象被觀察從X-射線binaries 和活躍太空星群的中堅力量(AGN) 。噴氣機形成和傳播機制依然是神奇並且新觀察將是需要的瞭解他們。演變時間表為噴氣機由X-ray binaries 生產以stellarmass 緊湊對象快速地是成千上萬時期比對於AGN 噴氣機。噴氣機的觀察從X-射線binaries 擁有巨大諾言為顯露的噴氣機動力學。在噴氣機的第一發現上從太空星群的X-射線

    binaries 是固定式, 大規模耳垂在X-射線[ 1 ] 並且收音機([ 2 ] 為回顧) 。更加緊密, 在緊湊對象附近, 噴氣機承擔二分明化身。你是緊湊噴氣機被發現在堅硬X-射線鬼狀態。緊湊噴氣機傾向於是平穩的, 至少對當前的觀察敏感性, 和, 因為名字會暗示, 變緊密, 以十倍的有角大小milliarcseconds 。噴氣機的另一化身從太空星群的黑洞候選人是大規模噴氣機。這樣噴氣機經常, 和或許總被形成在大彌撒累積率狀態, 在狀態轉折。經常這些噴氣機是分明一滴從各自的射入事件可能是解決的衝動的事件並且他們的行動可能被測量。我們將集中噴氣機這組在這回顧。
