In this paper, starting from Chandrasekhar's results, we find the solution of the Dirac equation with non-zero rest mass just out side the event horizon of a nearly extreme Kerr black hole and suce...

本文在此基础上，在近似极端Kerr 黑洞的事件视界附近找到了静止质量不为零的Dirac方程的解，并成功地导出了Hawking热谱公式，从而解决了Dirac粒子在Kerr 黑洞的Hawking蒸发问题。

The physical solutions of the Dirac equation with non-zero rest mass are found outside the event horizon of general spherically symmetric and charged evaporating black hole.

引 言自从Balbinot研究了考虑到反作用时的蒸发黑洞的Hawking辐射以来，这一研究领域引起了国内外理论天体物理学家的极大兴趣[1 5]。

Black hole mass, along with the ratio of the accretionrate to the Eddington accretion rate, is a fundamental parameter of active galactic nuclei.

与吸积率和爱丁顿吸积率的比率一道，黑洞质量也是活动星系核的一个基本参数。

The results show that the emission line region is at least several tens light-days away from the central black hole!

认为类星体发射线辐射区应在离中心黑洞几十个光日处，仅是一种理论解释。

But when dealing with large masses or time periods that are infinitesimally small, like the core of a black hole or the first moments after the Big Bang, neither quite works.

2但是在研究大质量物质或无限小的时间段时，比如，对黑洞的核或者是宇宙大爆炸后的最初时刻，二者都不能完美地加以解释。

From K-G Equation and Dirac equation,using 2-D invariant line element, the radius equation and event horizon formula of particles are obtained.A simpler method to the research of quantum effect of the scalar and vector particles in black hole with spherical symmetry is singgested.

分别从K-G方程和Dirac方程入手，利用简化后的二维不变线元，直接给出了粒子的径向方程和视界面方程公式，为研究球对称黑洞中标量粒子和矢量粒子的量子效应提供了一个更简单的方法。

After what had seemed countless years in the black places below, the round ivory moon that ranged high in the darkness above looked like yet another hole, this one leading to a cool, lamplit place beyond the sky, a country of shining rivers and forgetfulness.

之前，在这块土地下面，那些黑暗的地方，Simon仿佛经历了无数的岁月，此刻，象牙般明亮的圆月，在上方的天空中，将光辉洒落在这黑夜里，在Simon的眼中，那月亮仿似另一处洞穴，通往一个冰冷的、明亮的地方，那个地方，是在非常遥远的夜空中，在那个国度，应该有着微光闪闪的河流，而且让人无法忘怀。

I am just a common person, why I not only saw the identity of time and space, but also saw the multi-dimension. I saw the "curve light", and I saw the "not curve light" and "light of black hole" too, how amazing! How beautiful!

我是极普通的人呀，为什么我不仅看到了时间和空间的"同一性"还看到了它们的"多维性"；"弯曲的光"我看到了，"不弯曲的光"和"黑洞的光"竟然也被我看到了，太不可思义！

There's not much evidence to weigh," notes Jane Rissler of the Union of Concerned Scientists."This issue of nontarget effects is just a black hole, and EPA has very little good data at this point to conclude whether the monarch butterfly problem is real, particularly in the long term.

证据根本就不够，"环保科学家协会的瑞斯乐指出，"基改作物对非目标生物的影响这个问题根本就是个黑洞，环保署目前握有的数据太少，根本无法判断大桦斑蝶的问题是否严重，更遑论长期的评估。

Bao. I think he does not know the : quasar physics at all!: A simple reason: astronomers detected redshifts of quasars based on the spectr : al lines emitted from the emission line regions, which are 0.1 to 1 parsec (1p : arsec=3.26 light years) far away from the central black hole. Therefore there : is very little effect from the gravitational redshift!

观察到的类星体的光可在几日内有明显的变化，可见类星体的发光区大小在光日尺度以下，即使你认为类星体的光谱线产生于吸积盘，那么吸积盘的大小须在光日尺度以下才能不相矛盾，请你说出一个你认定的类星体吸积盘的大小尺度与该尺度内所具有的质量，及因此计算出的可忽略的引力红移。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
