　　陨石也称“陨星”，是地球以外脱离原有运行轨道的宇宙流星或尘碎块飞快散落到地球或其它行星表面的未燃尽的石质、铁质或是石铁混合的物质。2019年10月11日凌晨约0时16分前后，一颗陨石可能坠落在东北吉林省松原市附近，辽宁沈阳、吉林长春、吉林松原、黑龙江哈尔滨等黑龙江和吉林多地网友均目击到这颗陨石坠落时产生的火光。因为陨石是外太空的来物，陨石确定真假是需要仪器鉴定的，肉眼只有辅助的作用。大多数陨石来自于火星和木星间的小行星带，小部分来自月球和火星。陨石大体可分为石质陨石、铁质陨石，石铁混合陨石。陨石的平均密度在3～3.5之间，主要成分是硅酸盐。陨铁密度为7.5～8.0，主要由铁、镍组成。陨铁石成分介于两者之间，密度在5.5～6.0间。陨星的形状各异，最大的陨石是重1770千克的吉林1号陨石，最大的陨铁是纳米比亚的戈巴陨铁，重约60吨。中国陨铁石之冠是新疆青河县发现的“银骆驼”，约重28吨。
　　
　　A meteorite, also known as a meteorite, is an unburned mixture of stone, iron, or stone and iron scattered rapidly on the surface of the Earth or other planets by meteors or dust fragments from the universe that have left their original orbits outside the Earth. A meteorite may have crashed near Songyuan city in northeast China's Jilin province around 04:16 am on Oct 11, 2019. Netizens in Heilongjiang and Jilin provinces including Shenyang, Liaoning, Changchun, Songyuan and Harbin witnessed the firelight from the meteor. Because meteorites are from outer space, meteorites to determine the true and false is the need for instrument identification, the naked eye only auxiliary role. Most meteorites come from the asteroid belt between Mars and Jupiter, and a few from the moon and Mars. Meteorites can be roughly divided into lithic meteorites, ferroic meteorites, ferroic mixed meteorites. Meteorites have an average density of 3 ~ 3.5 and are mainly composed of silicates. The density of meteorite iron is 7.5 ~ 8.0, mainly composed of iron and nickel. The composition of meteorite is between the two and the density is between 5.5 and 6.0. Meteorites come in various shapes, the largest meteorite being the Jilin 1 meteorite weighing 1,770 kg, and the largest meteorite being the Goba meteorite in Namibia, weighing about 60 tons. The crown of Meteorite in China is a "silver camel" found in Qinghe County, Xinjiang province, weighing about 28 tons.
　　
　　陨石在高空飞行时，表面温度达到几千度。在这样的高温下，陨石表面融化成了液体。后来由于低层比较浓密大气的阻挡，他的速度越来越慢，融化的表面冷却下来，形成一层薄壳叫“熔壳”。熔壳很薄，一般在1毫米左右，颜色是黑色或棕色的。在熔壳冷却的过程中，空气流动在陨石表面吹过的痕迹也保留下来，叫“气印”。气印的样子很像在面团上按出的手指印。熔壳和气印是陨石表面的主要特征。若是你看到的石头或铁块的表面有这样一层熔壳或气印，那你可以立刻断定，这是一块陨石。但是落下来的年代较长的一些陨石，由于长期的风吹、日晒和雨淋，熔壳脱落了，气印也就不易辨认出来了，但是那也不要紧，还有别的办法来辨认。
　　
　　When meteorites fly high, their surface temperatures reach thousands of degrees. At such high temperatures, the surface of the meteorite melted into liquid. Later, as the thicker atmosphere in the lower layer blocked his speed, the melting surface cooled down, forming a thin shell called a "molten shell." The shell is very thin, generally around 1 mm, the color is black or brown. As the shells cool, traces of air flowing across the meteorite's surface remain, known as "gas prints." Air prints look a lot like finger prints on dough. Molten crust and gas seals are the main features of meteorite surfaces. If you see such a crust or vapor imprint on the surface of a rock or piece of iron, you can immediately tell that it is a meteorite. But some of the older meteorites, blown off by the wind, the sun, and the rain, are hard to make out. But that doesn't matter, there are other ways to make out.
　　
　　鉴定一块样品是否为陨石，可以从以下几方面考虑：1．外表熔壳：陨石在陨落地面以前要穿越稠密的大气层，陨石在降落过程中与大气发生磨擦产生高温，使其表面发生熔融而形成一层薄薄的熔壳。因此，新降落的陨石表面都有一层黑色的熔壳，厚度约为1毫米。2．表面气印：另外，由于陨石与大气流之间的相互作用，陨石表面还会留下许多气印，就象手指按下的手印。3．内部金属：铁陨石和石铁陨石内部是有金属铁组成，这些铁的镍含量很高（5%～10%）。球粒陨石内部也有金属颗粒，在新鲜断裂面上能看到细小的金属颗粒。4．磁性：正因为大多数陨石含有铁，所以95%的陨石都能被磁铁吸住。5．球粒：大部分陨石是球粒陨石（占总数的90%），这些陨石中有大量毫米大小的硅酸盐球体，称作球粒。在球粒陨石的新鲜断裂面上能看到圆形的球粒。
　　
　　To determine whether a sample is a meteorite, consider the following aspects: 1. Appearance melts shell: meteorite should pass through dense atmosphere before falling to the ground, meteorite produces high temperature in the process of falling and atmosphere friction, make its surface produces melting and form a thin layer of molten shell. As a result, newly landed meteorites have a black shell about 1 mm thick. 2. Surface airprints: In addition, meteorites leave many airprints on the surface, like fingerprints pressed by a finger, due to their interaction with the great airflow. 3. Interior metal: Iron meteorites and ferrocenites are composed of metallic iron, which is high in nickel (5-10%). Chondrites also contain metal particles, which can be seen on the fresh fracture surfaces. 4. Magnetism: Because most meteorites contain iron, 95% of meteorites are held by magnets. 5. Chondrites: Most meteorites are chondrites (90% of the total), which contain large millimeters-sized silicate spheres called chondrites. Circular chondrites can be seen on the fresh fracture surfaces of chondrites.

In addition to Ni and Fe, it also contains As, Mo, Mn, Zr, Nb, Ru, Rh, Ag, Cd, In, Sn, and Ir. A few iron meteorites also contain silicate inclusions. According to Fe, Zr, Nb, Ru, Rh, Agr and their structural characteristics, rare metal meteorites are classified into 13 groups. Meteorites are of great scientific value. By analyzing the radioactive material in meteorites, we can calculate the age of meteorites and infer the experience of meteorites after their formation. Meteorites for sale 138060-84568150000-80998 Meteorites are meteors from the universe outside the earth from the original orbit or into pieces scattered to the earth's stone body, it is the human direct understanding of the solar system stars precious and rare specimens, very valuable collection.
