查询词典 The Black Hole

These results are consistent with the scenario of small black hole and high accretion rate for NLS1s.

这些结果与窄线SeyfertⅠ型星系的小黑洞高吸积率模型一致。

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。

This dissertation is mainly about the scalar field in curved black hole spacetime backgrounds assumed to be asymptotic de Sitter space at infinity.

本文的主要内容是关于黑洞视界外部时空中的标量场，我们选择的黑洞时空在无穷远处是渐近de Sitter时空。

After a careful solution of the movement equation of particles as well as the Klein-Gorden equation in curved space-time, and the analgesic continuation of out going wave in the complex number r plane, it reaches a conclusion that the radiation spectrum of black hole is rigorous black body radiation spectrum.

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]。

And you have some idea of the force of a black hole.

你就会对黑洞的力量有某种概念。

But the existence of this black hole is too small, a few thousand part of a second.

但是，存在的这个黑洞是太小了，几千人参加的第二次。

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 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。

The other pigs all quite good eye pupil in the pigsty lookings at me, among them, the black skin of biggest a head of spoke up:" Take advantage o him have not yet bound the prison solid you, run hurriedly, that hole of the south wall we helped you the crest to open~~~~~, Originally they know that hole early!"

猪圈里的其他猪们都不错眼珠的看着我，其中最大的一头黑皮开口说话了：&趁他还没绑牢实你，赶紧跑啊，南墙上的那个洞我们帮你顶开了~~~~~啊，原来他们早知道那个洞！&

Legend Cave is a "bad one bucket black dragon" in, the hole drilled for the black dragon mountain formed by the collision, Jianfeng for the bad one off hilltops left by the sword the sword-shaped formation of rocks.

传说石洞是&吕洞宾斗苍龙&之地，洞为苍龙钻山所撞而成，剑峰为吕洞宾劈山后留下的宝剑形成的剑形山石。

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
