天外來福
隕石在高空飛行時，表面溫度達到幾千度。在這樣的高溫下，隕石表面融化成了液體。后來由于低層比較濃密大氣的阻擋，他的速度越來越慢，融化的表面冷卻下來，形成一層薄殼叫“熔殼”。熔殼很薄，一般在1毫米左右，顏色是黑色或棕色的。在熔殼冷卻的過程中，空氣流動在隕石表面吹過的痕跡也保留下來，叫“氣印”。氣印的樣子很像在面團上按出的手指印。 熔殼和氣印是隕石表面的主要特征。若是你看到的石頭或鐵塊的表面有這樣一層熔殼或氣印，那你可以立刻斷定，這是一塊隕石。但是落下來的年代較長的一些隕石，由于長期的風吹、日曬和雨淋，熔殼脫落了，氣印也就不易辨認出來了，但是那也不要緊，還有別的辦法來辨認。
When the meteorite flies at high altitude, the surface temperature reaches several thousand degrees. At this high temperature, the surface of the meteorite melts into a liquid. Later, due to the obstruction of dense atmosphere in the lower layer, his speed became slower and slower. The melting surface cooled down and formed a thin shell called "melting shell". The shell is very thin, usually about 1 mm, and the color is black or brown. In the process of melting shell cooling, the trace of air flowing on the surface of meteorite remains, which is called "air stamp". It looks like a finger print on a dough. The main characteristics of meteorite surface are melting shell and gas seal. If you see such a layer of molten shell or gas mark on the surface of stone or iron, you can immediately conclude that it is a meteorite. But for some meteorites that have fallen for a long time, due to the long-term wind, sun and rain, the melting shell has fallen off, and the air mark is not easy to identify, but that doesn't matter. There are other ways to identify them.
石隕石的樣子很像地球上的巖石，用手掂量一下，會覺得它比同體積的巖石重些。石隕石一般都含百分之幾的鐵，有磁性，用吸鐵石試一試便會感到。另外，仔細看看石隕石的斷面，會發現有不少的小的球粒。球粒一般有1毫米左右，也有大到2~3毫米以上的。90%以上的石隕石都有這樣的球粒，它們是隕石生成的時候產生的。是辨認石隕石的一個重要標記。鐵隕石的主要成分是鐵和鎳。其中，鐵占90%左右，鎳的含量一般在4~8%之間，地球上的自然鐵中鎳的含量一般不會有這么多。
The appearance of the meteorite is very similar to the rocks on the earth. If you weigh it by hand, you will feel that it is heavier than the rocks of the same volume. Meteorites generally contain a few percent of iron. They are magnetic. You can feel it when you try them with a magnet. In addition, if you look at the section of the meteorite carefully, you will find that there are many small chondrites. Generally, the size of the ball is about 1 mm, but also 2-3 mm or more. More than 90% of meteorites have such chondrites, which are produced when meteorites are formed. It is an important mark to identify meteorites. The main components of iron meteorites are iron and nickel. Among them, iron accounts for about 90%, and the content of nickel is generally between 4% and 8%. The content of nickel in the natural iron on the earth is generally not so much.
在鐵隕石上切割一個斷面，磨光后，用5%的硝酸酒精侵蝕，光亮的端面會呈現出特殊的條紋，像花格子一樣。這是因為鐵隕石本身成分分布不均勻，有的地方含鎳量多些，有的地方少些，含鎳量多的部分，化學性質穩定，不易被酸腐蝕，而含鎳量少的部分受酸腐蝕后，變得粗糙無光澤，這樣就由這些亮的和暗的部分組成了花格子一樣的條紋。除了極少數含鎳量特多的隕石外，都會出現這些條紋。這是辨認鐵隕石的一個主要方法。 石鐵隕石極少見，由石和鐵組成，它含有大致相等的鐵和硅酸鹽礦物。
Cut a section on the iron meteorite, polish it, and erode it with 5% nitric acid alcohol. The bright end surface will show special stripes, like a lattice. This is because the composition of the iron meteorite itself is not evenly distributed. Some places contain more nickel, some places are less, and some parts contain more nickel. Their chemical properties are stable and they are not easy to be corroded by acid. However, the parts containing less nickel become rough and lusterless after being corroded by acid. Thus, these bright and dark parts form the same stripes as lattice. Except for a few meteorites with high nickel content, these streaks will appear. This is a major method to identify iron meteorites. Ferrites are very rare, consisting of stone and iron. They contain about the same iron and silicate minerals.
在3類隕石中，石隕石最多，1976年3月8日，在我國吉林省吉林地區降落的一場大規模的隕石雨，便是一次石質的球粒隕石雨。這次隕石雨散落的范圍達四、五百平方公里，搜集到的隕石有一百多塊，總重量在2600公斤以上。其中，最大的一號隕石重1770公斤，是目前世界上搜索到的最重的一塊石隕石。第二位的是美國諾頓石隕石，重1079公斤。 鐵隕石比石隕石要重的多，最重的一塊在非洲納米比亞，名字叫戈巴隕石，有60噸重。在我國新疆的一塊大隕鐵重30噸，是世界的第三位。
On March 8, 1976, a large-scale meteorite rain fell in Jilin area of Jilin Province, China, which is a stone chondrite rain. The meteorite rain covers an area of four or five hundred square kilometers. More than one hundred meteorites have been collected, with a total weight of more than 2600 kg. Among them, the largest one weighs 1770 kg, which is the heaviest one in the world. The second is Norton meteorite, weighing 1079 kg. Iron meteorite is much heavier than stone meteorite. The heaviest one is in Namibia, Africa. Its name is Goba meteorite. It weighs 60 tons. A large meteorite iron in Xinjiang weighs 30 tons, which is the third largest in the world.
大多數流星體在進入大氣層時都會瓦解，估計每年仍有500顆左右，小至彈珠大至籃球的隕石落在地面上；但是，通常每年只有5至10顆流星會被發現墜落，并被科學家得知和尋獲。少數的隕石夠大，可以創造出巨大的撞擊坑；相對的，其它的隕石則因為不夠大，墜地時都已經達到終端速度，最多只能創造出一個小坑洞。
Most meteoroids will disintegrate when they enter the atmosphere. It is estimated that about 500 meteorites, ranging from marbles to basketball, still fall on the ground every year. However, only 5 to 10 meteors are usually found to fall every year, which are known and found by scientists. A few meteorites are big enough to create huge impact craters; in contrast, other meteorites, because they are not big enough, have reached the terminal speed at the time of falling, and can only create a small crater at most.
大隕石擊中地面時的速度可能仍接近它們的第二宇宙速度，在超高速的撞擊下會留下一個撞擊坑。坑洞的類型取決于隕石的大小、組成、破碎的程度、和進入的撞擊角度。這種碰撞的力量有可能造成廣泛的破壞。在地球上最常見到的超高速撞擊，是由最容易穿越大氣層的鐵隕石造成的。
Large meteorites may still hit the ground at a speed close to their second cosmic speed, leaving a crater under hypervelocity impact. The type of crater depends on the size, composition, degree of fragmentation, and impact angle of the meteorite. The force of this collision has the potential to cause extensive damage. The most common hypervelocity impact on earth is caused by iron meteorites, which are the most likely to cross the atmosphere.
鐵隕石造成的撞擊坑例子如，巴林杰隕石坑、奧德薩隕石坑、瓦巴坑和狼溪隕石坑，在這些隕石坑都發現相關聯的鐵隕石。相較之下，夠大的石質流星體或像彗星這樣的冰雪球或小行星，即使重量達到數百萬公噸，在進入和通過大氣層時，依然會被破壞而不會留下撞擊坑。雖然這種瓦解的事件很罕見， 它們會造成可以引起重視的振蕩，著名的通古斯事件可能就是這種事件。非常大的石質流星體，數百米直徑或這更大，質量達到千萬公噸或更重，可以墬落到地球表面，并撞擊出大撞擊坑，但是這是非常罕見的。這種撞擊通常都辦圍著巨大的能量，因此撞擊體會完全被摧毀，而沒有隕石能殘留下來（第一個被發現與石隕石有關聯的大隕石坑，是2006年五月提出報告的南非摩洛袞隕石坑）。
Large meteorites may still hit the ground at a speed close to their second cosmic speed, leaving a crater under hypervelocity impact. The type of crater depends on the size, composition, degree of fragmentation, and impact angle of the meteorite. The force of this collision has the potential to cause extensive damage. The most common hypervelocity impact on earth is caused by iron meteorites, which are the most likely to cross the atmosphere.
幾種現象是太小而無法造成超高速撞擊坑的墬落隕石目擊者需要提出的證據。流星體穿過大氣層時的火球可以非常明亮，甚至足以媲美太陽的強度，然而大多數都比較黯淡，甚至在白天而不會被注意到。有許多的顏色曾被報告過，包括黃色、綠色和紅色。隨著物件的碎裂，會有閃光和爆發。在隕石墜落時經常會聽到主要碎裂事件引起的激波產生爆炸、碎裂或隆隆的聲爆。在廣大的范圍內都可以聽到這種聲音，半徑可以達到數百公里或更大；有時可以聽到口哨聲或嘶嘶聲，但還缺乏理解。在火球經過之后，經常會看見煙塵的尾巴在大氣層內殘留好幾分鐘。
Several phenomena are too small to cause the hypervelocity impact crater to fall down the meteorite witnesses need to provide evidence. The fireball of meteoroids passing through the atmosphere can be very bright, even as strong as the sun, but most of them are dim, even in the daytime without being noticed. Many colors have been reported, including yellow, green and red. As the object disintegrates, there will be flashes and explosions. When a meteorite falls, it is often heard that the shock wave caused by the main fragmentation event produces an explosion, fragmentation or rumbling sound explosion. This kind of sound can be heard in a wide range, with a radius of hundreds of kilometers or more; sometimes whistles or hisses can be heard, but there is still a lack of understanding. After a fireball passes, the tail of soot is often seen to remain in the atmosphere for several minutes.
流星體在進入大氣層的過程中會被加熱，它的表面會融化和經歷燒蝕的體驗。在這個過程中，它們可以被雕塑成各種不同的形狀，在表面出現和留下被稱為氣印的淺層指紋狀凹陷。如果流星體保持固定的方位，沒有翻滾的前進一段時間，它可能會形成一個錐形的鼻錐或是熱遮罩的形狀。
Meteoroids are heated as they enter the atmosphere, and their surfaces melt and experience ablation. In this process, they can be sculpted into a variety of different shapes, appearing on the surface and leaving a shallow fingerprint like depression known as an airprint. If the meteoroid maintains a fixed orientation and does not roll forward for a period of time, it may form a conical nose cone or a heat mask shape.
