② 关于黑洞的知识(英语)•
黑洞是现代广义相对论中，宇宙空间内存在的一种天体。黑洞的引力很大，使内得视界内容的逃逸速度大于光速。
1916年，德国天文学家卡尔·史瓦西（Karl Schwarzschild）通过计算得到了爱因斯坦引力场方程的一个真空解，这个解表明，如果将大量物质集中于空间一点，其周围会产生奇异的现象，即在质点周围存在一个界面——“视界”一旦进入这个界面，即使光也无法逃脱。这种“不可思议的天体”被美国物理学家约翰·阿奇博尔德·惠勒（John Archibald Wheeler）命名为“黑洞”。
“黑洞是时空曲率大到光都无法从其事件视界逃脱的天体”。[1-3]
黑洞无法直接观测，但可以借由间接方式得知其存在与质量，并且观测到它对其他事物的影响。借由物体被吸入之前的因高热而放出和γ射线的“边缘讯息”，可以获取黑洞存在的讯息。推测出黑洞的存在也可借由间接观测恒星或星际云气团绕行轨迹取得位置以及质量。

③ 关于黑洞的英语作文
General theory of relativity prediction one kind of specially compact dark heavenly body. The big quality star occurs in its evolved last stage collapses shrinks, its material is specially compact, it has is called “ arc of visibility” the seal boundary, in the black hole is going into hiding the huge gravitational field, because the gravitational field is specially strong including photon any material can only go, but inescapable.Forms the black hole the star nuclear mass lower limit the approximately 3 time of solar qualities, certainly, this is the final star nuclear mass, but is not the star in the main foreword time quality. Except this kind of star level black hole, also has the other origin black hole - - so-called miniature black hole possibly to form in the universe early time, but the so-called ultra big quality black hole possibly exists in the galaxy central committee.
The black hole does not let, no matter what how in boundary any thing by outside seeing, this is this kind of object is called “the black hole” the reason. We are unable the transmitted light reflection to observe it, can only through receive its influence the periphery object to come the indirect understanding black hole. Although such said that but the black hole has its boundary, namely " event arc of visibility (arc of visibility) “. According to the guess, the black hole is the death star surplus, is when special big quality super-giant collapsing contracts proces. Moreover, the black hole must be a quality is bigger than Qiandela the Saika limit to form the stellar evolution to the last stage, the quality is smaller than Qiandela the Saika limit star is unable to form the black hole
④ 黑洞英文介绍
General relativity predicts a particularly dense dark objects. Evolution of massive stars in their late collapse occurs, the dense material in particular, it has one called "event horizon" of the closed border, a black hole hidden in a huge gravitational field, e to the gravitational field so strong, including in particular photon (ie the composition of light particles, the speed c = 3.0 × 10 ^ 8m / s), including any material can only be entered could not escape. The formation of a black hole minimum mass star's core is about three times the solar mass, of course, this is the last star of nuclear quality, rather than main sequence stars in the period of quality. In addition to this stellar-class black hole, there are other sources of black holes - the so-called micro-black holes may be formed in the early universe, the so-called supermassive black holes may exist in the central galaxy. A black hole can be found through the concept of electronic equipment.
The black hole within its borders to prevent any outsiders to see anything, which is the object known as the "black hole" of the reason. We were unable to observe the reflection of light it can only be affected indirectly understand the objects around the black hole. Having said that, but the black hole still has its borders, namely "event horizon (horizon)." It is assumed that the evolution of stellar black hole of death matter, is in a special super-massive stars collapse generated. In addition, the quality of a black hole must be larger than the Chandrasekhar limit of stellar evolution to the end of the form, quality, smaller than the Chandrasekhar limit of the star is unable to form a black hole.
翻译成汉语就是下面的意思----
广义相对论预言的一种特别致密的暗天体。大质量恒星在其演化末期发生塌缩，其物质特别致密，它有一个称为“视界”的封闭边界，黑洞中隐匿着巨大的引力场，因引力场特别强以至于包括光子(即组成光的微粒，速度c=3.0×10^8m/s)在内的任何物质只能进去而无法逃脱。形成黑洞的星核质量下限约3倍太阳质量，当然，这是最后的星核质量，而不是恒星在主序时期的质量。除了这种恒星级黑洞，也有其他来源的黑洞——所谓微型黑洞可能形成于宇宙早期，而所谓超大质量黑洞可能存在于星系中央。黑洞可以经由电子仪器观查到。
黑洞不让任何其边界以内的任何事物被外界看见，这就是这种物体被称为“黑洞”的缘故。我们无法通过光的反射来观察它，只能通过受其影响的周围物体来间接了解黑洞。虽然这么说，但黑洞还是有它的边界，即“事件视界（视界）”。据猜测，黑洞是死亡恒星的演化物，是在特殊的大质量超巨星坍缩时产生的。另外，黑洞必须是一颗质量大于钱德拉塞卡极限的恒星演化到末期而形成的，质量小于钱德拉塞卡极限的恒星是无法形成黑洞的。

黑洞、反物质和虫洞这三样东西本来就属于很难懂得东西，还要用英文表达的简单点的话有点难。但可以把它写的形象生动点：比方说黑洞是一个很黑的洞，就不要说黑洞是一个可以吸引周围一切物体的高质量天体。

⑦ 关于黑洞的三分钟英语演讲稿，私信发给我
Dear teachers and classmates, good morning, today I give everybody to bring the theme of black hole secret.
As everyone knows, the black hole is a celestial bodies. But a lot of people see him as a bottomless pit, it was wrong. Even some humanitarian to the way that the black hole mass is infinite, that is not correct.
In fact, the black hole has a lot of potential, the most common is the star level of the black hole, as the name suggests, she is and the stars involved. Stellar black holes are usually made by more than eight times the mass of the sun, the stars, the aging after collapse to form, so, the sun to become a black hole, or less qualified.
Why do stars aging will collapse? Because we all know that the universal gravitation, we usually blowing balloons if not tied shut up, will quickly leak, in the final analysis because of the balloon is elastic, the intermolecular gravitation.

Black Holes(黑洞)
Black holes are some of the strangest things in space. A black hole sucks in anything that gets near it. Nothing can escape from a black hole—not even light.
BLACK HOLES ARE STRONG
Nothing escapes from a black hole because its gravity is so strong. Gravity is a force that pulls one thing to another. Gravity is the force that holds you down on Earth. When you jump up, Earth’s gravity pulls you right back down. Earth’s gravity also makes the Moon orbit (go around) Earth.
The more matter (stuff) that is packed in a star, planet, moon, or other object, the stronger is its gravity. Gravity makes an object with more matter pull an object with less matter toward it. The Sun has a lot more matter than Earth. The Sun’s gravity pulls on Earth. It makes Earth orbit the Sun.
Matter is packed very tightly in some things and loosely in others. The matter that makes up an iron ball is packed much tighter than the matter that makes up a bag of feathers. A scientist would say that an iron ball is much denser than a bag of feathers.
A black hole is denser than anything you could imagine. A black hole could have a million times more stuff than our Sun. All of this stuff would be packed into an area smaller than a city. The force of gravity from so much stuff packed into such a small area is awesome.
WHERE DO BLACK HOLES COME FROM?
Astronomers and physicists think black holes come from dying stars. A dying star burns out and stops shining. All the stuff that makes up the star starts falling in on itself. The star gets denser and denser. If the star is big enough and has enough matter, it could get dense enough to become a black hole.
STUDYING BLACK HOLES
No one has really seen a black hole. You cannot see black holes because they do not give off any kind of light. Physicists used math to predict that black holes exist.
Astronomers look for signs of black holes. Astronomers study powerful rays coming from stars in deep space. The stars seem to be orbiting black holes. Astronomers think that black holes are sucking gas from the stars, and this makes the stars give off X rays.
Galaxies are enormous groups of stars. Astronomers think that most galaxies have huge black holes at their centers. The Hubble Space Telescope took pictures of a disk of hot gases at the center of our own Milky Way Galaxy. Astronomers think this disk is going around an enormous black hole right in the center of our galaxy.
黑洞(黑洞)
黑洞是在太空的一些奇怪的事。一个黑洞吸入任何靠近它。没有什么能逃脱黑hole-not甚至光。
黑洞是强大的
没有逃离黑洞因为它的引力是如此的强烈。重力是一股力量,把一件事到另一个地方。重力是地球上把你的力量。当你跳起来时,地球引力把你拉回来。地球的引力也让月球地球轨道(四处)。
越多事情(东西),装在一个明星,行星,月亮,或其他对象,它的引力就越强。物体重力使一个对象有更多物质拉向它用更少的问题。太阳比地球更重要。地球上太阳的引力拉。它使地球轨道太阳。
问题是包装非常紧密一些事情和松散。这件事让一个铁球比这件事更紧了,一袋羽毛。科学家会说,一个铁球比一袋密集的羽毛。
一个黑洞的密度比你能想象的任何东西。一个黑洞可能更多的东西比太阳的一百万倍。所有的这些东西会比城市更小的区域里。这么多东西的重力挤进这么小的区域是可怕的。
黑洞来自哪里?
天文学家和物理学家认为黑洞来自垂死恒星。垂死的恒星燃烧停止照耀。所有的东西,明星开始下降。星星变得越来越密集的。如果恒星足够大,有足够的物质,它能密度足以成为一个黑洞。
研究黑洞
没有人真正看到一个黑洞。你看不见黑洞因为他们不发出任何类型的光。物理学家利用数学预测,黑洞的存在。
天文学家寻找黑洞的迹象。天文学家研究强大的射线来自恒星外层空间。星星似乎环绕黑洞。天文学家认为,黑洞吸气体从恒星,这使得星星发出X射线。
星系是巨大的恒星组。天文学家认为,大多数星系有巨大的黑洞中心。哈勃太空望远镜拍照片的一个磁盘的热气体在我们的银河系的中心。天文学家们认为这个磁盘将在一个巨大的黑洞就在银河系的中心。
⑨ 什么是黑洞卞毓麟阅读答案
定义：由一个只允许外部物质和辐射进入而不允许物质和辐射从中逃离专的边界即视界属(event horizon)所规定的时空区域
黑洞是一种引力极强的天体，就连光也不能逃脱。当恒星的半径小到一定程度，小于史瓦西半径时，就连垂直表面发射的光都无法逃逸了。这时恒星就变成了黑洞。说它“黑”，是指它就像宇宙中的无底洞，任何物质一旦掉进去，“似乎”就再不能逃出。由于黑洞中的光无法逃逸，所以我们无法直接观测到黑洞。然而，可以通过测量它对周围天体的作用和影响来间接观测或推测到它的存在。
