查询词典 black hole

In the core of the larger spiral structure of NGC 1300, the nucleus shows its own extraordinary and distinct "grand-design" spiral structure that is about 3,300 light-years long. Only galaxies with large-scale bars appear to have these grand-design inner disks — a spiral within a spiral. Models suggest that the gas in a bar can be funneled inwards, and then spiral into the center through the grand-design disk, where it can potentially fuel a central black holes. NGC 1300 is not known to have an active nucleus, however, indicating either that there is no black hole, or that it is not accreting matter.

星系演化除了像两个星系相撞那样的剧烈作用之外，还有自己内部很慢的演化，因为一个星系总会有一些引力不稳定，如上图中的NGC1300，它是一个棒旋星系，这种bar结构导致的引力不完全对称会驱使很多气体和尘埃损失角动量往里面落，我们可以清楚的看到dust lanes，有点像黑洞的吸积，但这个星系是个非活动星系，目前还没有黑洞存在的明确证据，but我相信肯定是有的，没有比在星系中心放一个黑洞再完美不过的事情了，或许这些下落的dust lanes是黑洞发光的开始呢。

But there are images of binary star systems consisting of one normal star and one black hole, and of the central regions of Galaxies that are believed to contain black holes.

通过对弯曲时空中粒子的运动方程克莱因—高登方程的求解，并将出射波解在复平面做解析延拓，得出黑洞的辐射谱为严格的黑体辐射谱[1-2]。

Previously, the smallest known black hole would weigh about 6.3 times as much as the Sun, and some black holes tip the scales at millions or even billions of times that of our Sun.

更加准确的办法是通过黑洞的外观大小和其周围圆盘气体流所释放的 X 射线的相关性，天文学家能更加准确给黑洞称重。

The quasinormal modes and the late-time tails of perturbational fields in the black hole spacetime are related to the identification and stability of the black holes.

然而黑洞物理学中还有许多问题人们尚未弄清楚，像黑洞熵的统计起源、黑洞信息疑难以及黑洞是否稳定等都是黑洞物理中非常重要而有待解决的问题。

The black dot was equal to a black hole in space and the squiggly lines were meant to be people or things or just your basic atoms that got lost there.

而那些黑线却意味着是人，亦或是事物，或者干脆是你身上丢掉的一颗原子。

A pustulent vegetable. A retarded fossil . The black hole into which the universe continually implodes. Not even amoeba can survive on a keyboard you've touched.

当那个男子把黑洞洞的抢口对着她的时候，她吓得软软地放下了拉着小梅的手。眼睁睁地看着小梅被他拉上了车，看到小梅用求助的眼光看着她，而她却站在那，不敢喊也不敢叫。这时从对面走来一个比她们大一些的女孩子，看到此情景，她大步的向前，要那个人放了小梅，还亮出了她的记者身份。可没想到，那男人看她的记者证后，抢口却射出了毫不留情的子弹，她倒在了她们面前。
