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。一個黑洞吸入任何靠近它。沒有什麼能逃脫黑hole-not甚至光。
黑洞是強大的
沒有逃離黑洞因為它的引力是如此的強烈。重力是一股力量,把一件事到另一個地方。重力是地球上把你的力量。當你跳起來時,地球引力把你拉回來。地球的引力也讓月球地球軌道(四處)。
越多事情(東西),裝在一個明星,行星,月亮,或其他對象,它的引力就越強。物體重力使一個對象有更多物質拉向它用更少的問題。太陽比地球更重要。地球上太陽的引力拉。它使地球軌道太陽。
問題是包裝非常緊密一些事情和鬆散。這件事讓一個鐵球比這件事更緊了,一袋羽毛。科學家會說,一個鐵球比一袋密集的羽毛。
一個黑洞的密度比你能想像的任何東西。一個黑洞可能更多的東西比太陽的一百萬倍。所有的這些東西會比城市更小的區域里。這么多東西的重力擠進這么小的區域是可怕的。
黑洞來自哪裡?
天文學家和物理學家認為黑洞來自垂死恆星。垂死的恆星燃燒停止照耀。所有的東西,明星開始下降。星星變得越來越密集的。如果恆星足夠大,有足夠的物質,它能密度足以成為一個黑洞。
研究黑洞
沒有人真正看到一個黑洞。你看不見黑洞因為他們不發出任何類型的光。物理學家利用數學預測,黑洞的存在。
天文學家尋找黑洞的跡象。天文學家研究強大的射線來自恆星外層空間。星星似乎環繞黑洞。天文學家認為,黑洞吸氣體從恆星,這使得星星發出X射線。
星系是巨大的恆星組。天文學家認為,大多數星系有巨大的黑洞中心。哈勃太空望遠鏡拍照片的一個磁碟的熱氣體在我們的銀河系的中心。天文學家們認為這個磁碟將在一個巨大的黑洞就在銀河系的中心。

❽ 一篇關於天文學的英語短文

The Greek Heavenly Thoughts

The Greek was the first recognize the distinction between the natural and the supernatural. In other words , they found the nature, since then, the cosmology(宇宙學) could never be maintain a system of myth.

Graally, the Greek believed themselves to live in a cosmos, and considered the cosmos to be an entirely natural place. Besides they saw an order in the cosmos. The order, to them, not only means an arrange, but also a good order, and also a beautiful, elegant order. With an optimism(樂觀主義), they believed the order, and the cosmos were comprehensible(可知的), and furthermore, could be described in words and numbers. When the Greek formed these crucial ideas, some earliest philosophers and scientists were important and influential. The Milesians(米利都學派得的哲學家), including Thales(泰勒斯), Anaximander(阿納克西曼德), described the cosmos in entirely natural terms for the first time. Heraclitus(赫拉克立特) insisted that the cosmos worked according to a logos(理性), which mean 「word」, 「account」, 「measure」, and 「proportion」, and if we grasp this logos, the cosmos could be understood and described well.

After the Greek accepted the idea that the cosmos was a natural place and comprehensible, some pre-Socratics(前蘇格拉底時代德哲學家) overcame some significant conceptual(觀念上的) hurdles to achieve a more sophisticated cosmology. There was the move from a hemispherical(半球形) universe to a spherical(球形) one, and a earth supported by water to supported by air, and then to one which need no support. In the earlier Greek cosmologies, objects were thought to drop in parallel straight lines from the top of the cosmos to the bottom, this led to the problem why the earth doesn』t fall to the bottom of the cosmos, so in this sort of the cosmos, something is required to support the earth. Then Aristotle placed the earth at the center of the cosmos, there was no the problem of the earth dropping. He believed that objects moved to the center of the cosmos, that is the earth itself.

The idea that the earth was central and stable dominated Greek astronomy and cosmology. In Greek minds, it can explain many phenomena. Firstly, the experience told Greek, if one was in rapid motion, he certainly knew about it, so they thought, if the earth has a daily rotation from west to east, there should be constant wind from east to west; if the earth is in motion around the sun, all objects will sweep off the face of the earth. Secondly, because they had no knowledge of gravity, they believe if the earth in rapid motion, it will disintegrate(解體). Thirdly, if the earth takes up different positions relative to the stars(恆星), there should be a stellar parallax(恆星視差量), one can detect slight changes in the apparent positions of the stars from the earth.

When the Greek physics, astronomy, philosophy and common sense all seemed to indicate an immobile earth, there was an important consequence, all of the motions of the heavens were real motions to the earth, not apparent ones e to the motion of the earth.

At the outset, Greek observational astronomy was rather divorced(背離) from philosophical speculation about the nature of the cosmos. Some observed the heavens and took careful notes of what they saw, some proced cosmological models based on general philosophical considerations. But no one gave a cosmological model that were anywhere near explaining, in a precise manner, the phenomena that had been record. The Pythagoreans(畢達哥拉斯學派的哲學家) made the first attempt. They believed in the center of the cosmos was a fire, not the sun, the fire was shield from the earth by a body known as the counter earth. The model was vague and speculative, and the earth moves around the fire, and between the fire and earth, there was the counter earth. Plato(柏拉圖) proced a slightly better model, had central earth, with the sun, the moon, the five planets and the stars orbiting around it. Then it was a basic assumption of Greek astronomy and cosmology, if some motions seems not circular or regular, almost all Greek philosophers and scientists would consider these as some combination of several circular and regular motions. Neither of two models could account for two important phenomena relating to the point at which the sun sets. The sun does not always set e west(正西方). Where the sun sets ring a year changes from a maximum of 23.5º north of west to a maximum of 23.5°north of west. Solstices(至日,包括冬至、夏至) occur at the maximum points, while equinoxes(分日,包括春分、秋分) occur at the e west. Later Plato gave the first model that could give a reasonable account for these phenomena. The model was one of the most important Greek cosmological models. Plato made the first serious attempt to unite astronomical phenomena and cosmological traditions. He insisted that the sun, the moon, have a combination of two regular circular motions, that』s to say, the sun and the moon have a second motion in addition the daily one, offset(偏移) at an angle to it. As to the five planets, which are wandering in the heaven apparently, Plato gave a similar but more complex explanation. The model could give a reasonable explanation approximately, but couldn』t explain the planets exceptive motions. They will progress against the background of the fixed stars over a year or two, or even longer, then they will halt suddenly, and go in the other direction for a while, stop again, after that, progress in the normal direction. Facing a series strange exceptions and motions of the planets, Eudoxus(人名,難以翻譯,重要的哲學家、科學家) thought regressively(回歸,追本溯源). He was a pupil of Pythagorean, and had a close relationship with Plato. About planets, Plato』s model had two regular circular movements for each planet, Eudoxus gave four circular movements for each planet. In this model, the first sphere (環), generate a daily motion; the second generate the motion along the ecliptic(黃道), the other two proce a pattern like the figure 8 laid on its sides(行星出現在黃道正負8度范圍內). Besides, Eudoxus had a record of planets』 motion, and made a good use of mathematics, so compared with Plato』s model, his is more sophisticated.

Eudoxus』 model was excellent model for a long time, but there were some inherent difficulties. Because the distance between the earth and each one of five planets that we can see with naked eyes, always changes, it is not difficult to find that all planets』 size are varying apparently. Eudoxus can』t cope with the phenomenon, in his model, the distances between the earth and the planets are constant, that means the size of planets can』t vary. Account for these problems, Ptolemy(托勒密) proced a whole new system which was to last for nearly 1500 years. The system was based on combination of regular circular motions too. He gave up concentric(同心圓) sphere model in favor of a system based on a device, the epicycle(本輪,天文模型的一種). The epicycle is a combination of two regular circular motions, but not around the same center. The center of smaller circle moves around the larger circle. The two circles can proced many complex patterns, because these patterns, Ptolemy was able to explain most problems that beset the concentric sphere model, including the variation of apparent size, the brightness, the velocity(速度) of the planets. Besides the epicycle, Ptolemy made another subtle change, the earth is offset from the center of the sun』s orbit. So the model can account for that seasons have slightly different lengths. Now before the telescope was invented and new phenomena that can』t be found with naked eyes were detected, the model is the best in the ancient times.

After talking about some important Greek cosmological models, we have to mention an exceptive astronomer, Aristarchus(阿里斯塔克斯). He is the first one who have a revolutionary thinking that the earth is orbiting around the sun. But sadly, we don』t know how and why he can be aware this without any idea about gravity and the phenomena which only can be detected with telescope, only we know he is a follower of Aristotle.

METEOR (Metric for Evaluation of Translation with Explicit ORdering) is a metric for the evaluation of machine translation output. The metric is based on the harmonic mean of unigram precision and recall, with recall weighted higher than precision. It also has several features that are not found in other metrics, such as stemming and synonymy matching, along with the standard exact word matching. The metric was designed to fix some of the problems found in the more popular BLEU metric, and also proce good correlation with human judgement at the sentence or segment level This differs from the BLEU metric in that BLEU seeks correlation at the corpus level.

Example alignment (a).Results have been presented which give correlation of up to 0.964 with human judgement at the corpus level, compared to BLEU's achievement of 0.817 on the same data set. At the sentence level, the maximum correlation with human judgement achieved was 0.403.[1]
