event horizon iˈventhəˈraizən 短语⁵⁸³³³ 基本例句 视界 And if now you look at this part of this equation and you take the radius on one side, of the event horizon equals 2 MG divided by c squared, and that's how I found that equation. 这一部分,在一边代入半径值,你会得到视界的半径,2MG除以 c的平方,这是得到等式的方法,不好意思我讲太快了。163 In effect, an event horizon has formed in the river, preventing waves from making their way out. 结果,小溪就形成了一个视界,阻止了波浪逃离整个溪流的逆流。 ecocn It's surrounded by the event horizon, a region beyond which objects need to travel faster than the speed of light to escape the black hole. 包围着奇点的边界叫做视界。物体要想逃离黑洞并越过视界必须以大于光速的速度运动。 yeeyan The problem is that these stable orbits would only exist once you have crossed the threshold of the event horizon, where time and space flow into one another. 问题是,只有曾穿过黑洞视界的临界才会存在稳定轨道,那里时间与空间会流入其他地方。 cri A virtual particle or antiparticle may be captured by the black hole’s gravity. Once within the event horizon, it cannot escape and its abandoned partner has no option but to become real. 一个真实粒子或反粒子也许会被黑洞的引力吸入,一旦在黑洞边界里,它便无法逃离,而被抛弃的一半没得选择只能变为真的。 ecocn Assuming that the protective event horizon evaporates along with the black hole, the singularity at the center could be exposed at the moment the black hole winks out of existence. 假设起保护作用的黑洞边界随着黑洞一起消失,中心的奇点就会在黑洞消亡的那一刻暴露出来。 yeeyan Dr Hawking’s insight came from considering what happens in the empty space just outside the event horizon. 霍金博士的思想源于对视界之外的真空发生的事情进行的深思熟虑。 ecocn Essentially, the leading edge of the chasing pulse sucks it in, acting like the event horizon of a black hole. 从本质上来讲,后来追逐的脉冲的主导边缘将慢脉冲吞噬了,就像一个黑洞的视界那样。 ecocn If M is the mass of the Earth, the radius of the event horizon is one centimeter. 视界的半径,是1厘米,若 M是太阳的质量。163 If M is the mass of the sun, the radius of the event horizon is three kilometers. 视界的半径就是,3公里,若 M是太阳的三倍重。163 In his paper, Dokuchaev studies hypothetical orbits in the area between the event horizon and the singularity to understand their dynamics. 在他的论文中,多库恰耶夫研究了位于视界和奇点之间的假设性轨道,来理解它们的动态变化。 yeeyan It became apparent that it had a surfacewhich got named an event horizon which you could get into but not out of. 很显然它有一个只能进去却无法出来的表面后来称其为视界。 iciba Once something has passed through the so-called event horizon that surrounds this region, it is doomed to a one-way trip. 一旦某些东西穿越了环绕这个区域的所谓“视界”,那这个东西就注定无法返回。 ecocn The projection starts off at Planck scale lengths at the Universe’s event horizon, but its projection becomes blurry in our local space-time. 宇宙视界的投射发生于普朗克尺度,所以在我们所在的时空尺度上,这一投射发生了模糊。 yeeyan They have not only an outer event horizon but also an inner horizon, called a“ Cauchy” horizon. 它们不仅有一个外边界,还有一个内边界,称为“柯西”视界。 yeeyan To be sucked in by a black hole, you need to reach its event horizon, the one-way boundary beyond which nothing can escape. 要被一个黑洞吸入,你必须抵达它的视界,即:超过这个边界任何都无法逃离的单程边界。 bbs.chinadaily.com.cn Using the Gauss- Bonnet theorem, Stephen Hawking proved that the topology of the event horizon of a four dimensional black hole is a2- sphere. 使用高斯-博内定理, 史蒂芬·霍金证明一个四维黑洞活动视界的拓扑结构是2个球体。 iciba Whatever their origin, all black holes have an“ event horizon”, within which gravity is so intense that nothing can escape. 不论黑洞有何起源,他们都有“黑洞边界”,里面引力强大,什么都无法逃离。 ecocn |
