你知道陨石如何投资吗

陨石

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 the meteorite is flying at high altitude, the surface temperature of the meteorite reaches thousands of degrees. At such a high temperature, the surface of the meteorite melts into a liquid. Later, due to the obstruction of the lower layer of thicker atmosphere, his speed became slower and slower, and the melting surface cooled down to form a thin shell called the "melt shell". The shell is very thin, usually around 1 millimetres, and the color is black or brown. In the process of cooling the molten shell, the trace of the air flowing through the surface of the meteorite is also retained, called "gas seal". The air print looks like the finger printed on the dough. The main features of the surface of the meteorite are the molten shell and gas print. If you see the surface of stone or iron has a layer of melted shell or gas seal, you can immediately conclude that this is a meteorite. But some meteorites that fall down for a long time are not easy to identify the gas seals due to long wind, sun and rain. But that doesn't matter. There are other ways to identify them..

石陨石

石陨石的样子很像地球上的岩石,用手掂量一下,会觉得它比同体积的岩石重些。石陨石一般都含百分之几的铁,有磁性,用吸铁石试一试便会感到。另外,仔细看看石陨石的断面,会发现有不少的小的球粒。球粒一般有1毫米左右,也有大到2~3毫米以上的。90%以上的石陨石都有这样的球粒,它们是陨石生成的时候产生的。是辨认石陨石的一个重要标记。铁陨石的主要成分是铁和镍。其中,铁占90%左右,镍的含量一般在4~8%之间,地球上的自然铁中镍的含量一般不会有这么多。

The stone meteorite looks much like the rock on the earth and weighs it by hand and thinks it is heavier than the same volume of rock. Stone meteorites usually contain a few percent of iron, magnetic, magnet it will feel. In addition, a careful look at the cross section of the stone meteorite will find a lot of small pellets. The pellets usually have about 1 millimeters or more than 2~3 millimeters. More than 90% of the stone meteorites have such chondrules, which were produced when meteorites were formed. It is an important marker for identifying stone meteorites. Iron and nickel are the main components of the iron meteorites. Among them, iron accounts for about 90%. The content of nickel is generally between 4~8%, and the content of nickel in the earth's natural iron is generally not so much.
