WHAT IS A METEORITE? 什么是陨石?
A meteorite is a piece of iron, stone, or stony-iron composite that has fallen to Earth from outer space.陨石是一块铁,石,石铁复合,已从地球外层空间。 Most meteorites originated within the Asteroid Belt between Mars and Jupiter, and were once part of a planet or large asteroid.大多数陨石起源于火星和木星之间的小行星带,一旦一颗行星或大小行星的一部分。 A few meteorites come from the Moon and Mars, and a few others may possibly be fragments of cometary material.少数陨石来自月球和火星,和其他一些可能是彗星物质的片段。

Meteorites are valuable both to science and the collecting community.陨石是宝贵的科学和收集社会。 A modest portion of meteorite finds should be made available to academia for study.陨石发现的一个温和的部分应提供给学术​​界进行研究。 Identification and classification of a new meteorite is a fairly complicated process that can only be handled by a very small number of specialists.一个新的陨石鉴定和分类是一个相当复杂的过程,只能由极少数的专家处理。 We have close professional relationships with top academic institutions and can advise you on how best to proceed if you have a real meteorite.我们必须密切与顶尖学术机构的专业的关系,可以告诉你,如果你有一个真正的陨石就如何最好地进行。


SOME BASIC FACTS 一些基本事实

Meteorites are attracted to magnets 陨石被吸引到磁铁
Meteorites contain a great deal of extraterrestrial iron, even the ones that look like terrestrial rocks (stony meteorites).陨石包含一个很大的外星铁,即使是那些看起来像陆地岩石(石陨石)。 Just like a common nail or ball bearing, they will easily stick to a magnet, but they are not magnetic .就像一个共同的指甲或球轴承,他们将很容易粘到一块磁铁,但他们没有磁性。 Test your find with a good hardware store magnet, or a rare earth magnet (offered for sale on our web site).测试你找到了良好的硬件存储磁铁,或稀土永磁(我们的网站上出售)。 An extremely small percentage of meteorites (far less than one in a thousand) do not show strong attraction to a magnet.陨石(远远超过了千分之一的)的一个非常小的比例不显示磁铁强大的吸引力。 They are so rare that we usually discount anything that will not adhere to a magnet.他们是如此罕见,我们通常折扣任何不会坚持一个磁铁。 Those meteorites look similar to volcanic rocks from Earth, and are not metallic in appearance.类似于这些陨石从地球上的火山岩石,并在外观上没有金属。

Meteorites are heavy 陨石重
Most meteorites are much denser than ordinary Earth rocks. 大多数陨石比普通地球岩石多密集。 The thing most people say when they hold a meteorite for the first time is, "Wow! It's so heavy!" 首次举行的陨石时,大多数人说他们的东西是,“哇!它是如此沉重! The unusual weight is due to high iron content. 不寻常的重量是由于铁含量高。 Even stone meteorites will feel heavier in the hand than most Earth rocks. 即使是石陨石会觉得较重,比大多数地球岩石的手。

Meteorites are not radioactive 陨石是没有放射性
Meteorites likely traveled in space for millions of years before visiting us here on Earth. 陨石在太空中可能走过了数百万年之前,地球上访问我们在这里。 They were bathed in cosmic rays, but are not dangerous or radioactive. 他们沐浴在宇宙射线,但并不危险或放射性。 Some meteorites, such as Canyon Diablo from Arizona, contain micro diamonds but those gems are nearly invisible to the naked eye and can only be seen after cutting a specimen. 如从亚利桑那州的大峡谷暗黑的一些陨石,包含微钻石,但这些宝石是肉眼几乎看不见,只能看到切割后的标本。 Meteorites do not contain emeralds, gold (except possibly as a trace element), fossilized aliens, or common earth minerals such as quartz. 陨石不包含翡翠,黄金(除了可能作为一种微量元素),化石的外国人,或共同的地球矿物,如石英。 If your rock looks just like other earth rocks, it probably is one. 如果您的岩石看起来就像其他的地球岩石,它可能是其中之一。 Meteorites look and feel different from the ordinary rocks around them. 陨石的外观和感觉从他们身边的普通岩石不同。

CHARACTERISTICS OF METEORITES 陨石的特征

Attraction to a magnet 一块磁铁的吸引力
Meteorites will easily stick to a magnet.陨石很容易粘到磁铁上。 Use a good quality magnet to test your specimen.使用质量好的磁铁来测试您的标本。 If you do not have one, we offer for sale the same powerful rare earth magnets used in our television series Meteorite Men .如果你没有,我们在我们的电视系列陨石男子用同样强大的稀土磁铁要约出售。 These indispensable magnets are always found in Geoff's meteorite hunting kit and on his pick.这些不可缺少的磁铁,总是发现杰夫的陨石狩猎套件和他挑。 Because of our rare earth magnet's powerful pull, meteorites actually jump right to it!由于我们的稀土磁铁的强大拉动,陨石实际上跳的权利!

Weight 重量
Meteorites are dense, they will feel heavier than ordinary Earth rocks.陨石密集,他们会觉得比普通的地球岩石重。

Fusion crust 熔壳
Recently fallen meteorites will exhibit fusion crust .最近下跌的陨石将展出熔壳。 This is a thin black rind, sometimes shiny, sometimes matte black, which is acquired during burning in the atmosphere.这是一个细的黑色外皮,有时有光泽,有时粗面黑,这是在大气中的燃烧收购。 A freshly fallen stone meteorite will look much like a charcoal briquette.一个刚倒下的石陨石看起来很像一个木炭型煤。 Even stone meteorites that have been on the Earth for a long time usually retain some fusion crust and almost always appear much darker than ordinary rocks.即使石陨石在地球上很长一段时间通常会保留一些熔壳,几乎总是比普通的岩石暗。

Surface features 表面特征
Meteorites, especially irons, often acquire "regmaglypts" (thumbprints) caused when their surface melts during flight.陨石,特别是铁杆,经常获得“regmaglypts”(指纹)引起的表面时,他们在飞行过程中融化。 Stone meteorites sometimes display regmaglypts too, but they are not as well defined as in irons.石陨石,有时显示regmaglypts太多,但他们不是铁杆以及定义。 Meteorites, particularly irons, may also show angular features such as points and ridges, and also flowlines which are caused by melting.陨石,特别是铁杆,也可能会出现点和山脊,也融化造成的管线,如角的功能。 Many of the suspected meteor-wrongs we receive are common terrestrial volcanic rocks.怀疑流星的是非曲直,我们收到许多共同的陆相火山岩。 Volcanic rocks (along with other types) often contain small, deep holes, as if they had been repeatedly punctured with a needle.火山岩(以及其他类型)通常包含小,深洞,如果他们曾多次用针头刺破。 These holes are called vesicles and are caused by gas escaping when lava cools, but meteorites do not contain vesicles.这些漏洞被称为泡和逃避熔岩冷却时气体造成的,但陨石不含有囊泡。

  陨石鉴定(上) An iron meteorite which fell in Russia in 1947. 铁陨石在俄罗斯于1947年下降。 It displays many fine regmaglypts. 它显示了许多美好的regmaglypts This is what a freshly-fallen iron meteorite would look like 这是一个刚倒下的铁陨石看起来

陨石鉴定(上)
An older iron meteorite in as-found condition. 在符合条件的旧的铁陨石。 This meteorite has been on Earth for centuries. 该陨石在地球上已经几百年。 Note the surface features (regmaglypts) and rust 注意表面特征(regmaglypts)和铁锈
陨石鉴定(上)
An iron meteorite found in the Namibian desert. 在纳米比亚沙漠发现的铁陨石 This meteorite has been on Earth for centuries. 该陨石在地球上已经几百年。 Note the angular shape, large regmaglypts and desert patina 注意角的形状,大regmaglypts和沙漠铜绿

 

  

 

Metallic flakes 金属薄片
Nearly all stone meteorites contain small, bright metallic flakes.几乎所有的石陨石中含有小,明亮的金属薄片。 These are tiny pieces of extra-terrestrial iron and nickel.这些额外的地面的铁和镍的小块。 You can usually see them after slicing off a small piece, or removing a corner with a bench grinder. Please note! We recommend that you do not cut up your suspected meteorite, or otherwise damage its appearance.通常可以看到他们后切了一小块,或删除一个角落里,一个砂轮机,请注意!我们建议您不要削减你的怀疑陨石,或以其他方式破坏其外观。 A meteorite with a beautiful or interesting shape will be worth less to collectors if its end has been hacked off.一个与美丽或有趣的形状的陨石将是值得收藏家如果已经被黑客入侵了它的尽头。 Ask a meteorite professional or accredited lab to do your cutting and testing.问陨石的专业或认可的实验室做你的切割和测试。

Chondrules 陨石
Small, colorful, grain-like spheres which occur in most stone meteorites, hence the name of these stone meteorites — chondrites.体积小,色彩艳丽,类似粮食领域发生在大部分石陨石,故名这些石陨石 - 球粒陨石。 Chondrites are the most common type of meteorite.球粒陨石是最常见的类型的陨石。 Chondrules are not found in earth rocks.陨石在地球岩石中都没有发现。

Rust or patina 生锈或铜绿
Meteorites which have been on the Earth for a long time will likely start to rust, or — in dry desert environments — acquire a "patina" caused by oxidation.有很长一段时间在地球上的陨石可能会开始生锈,或 - 在干燥的沙漠环境 - 收购氧化造成的“铜绿”。 The natural patina of irons is often yellow/ochre, red, or orange.铁杆的自然铜锈往往是黄色/赭色,红色或橙色。陨石鉴定(上)METAL FLAKES 金属薄片
Most stone meteorites contain abundant small metallic flakes composed of nickel and iron. 大部分石陨石中含有丰富的的镍和铁组成的小金属片。 These flakes cause stone meteorites to feel heavy 这些薄片事业感到沉重的石陨石

         常见问题及一些误解

"I want to find my own meteorite. Where do I look?" “我想找到我自己的陨石。,我在哪里看?
Meteorite hunting is an unusual occupation and the best way to succeed is to understand what meteorites are, where they come from, and what equipment and techniques are best suited to find them.陨石狩猎是一个不寻常的职业,并取得成功的最好方法是了解陨石是什么,他们来自哪里,什么设备和技术最适合找到他们。 Geoff Notkin of Aerolite Meteorites and star of Science Channel's award-winning hit series Meteorite Men, has written the definitive guidebook to searching for space rocks. Meteorite Hunting: How To Find Treasure From Space can be ordered online, or directly from us.陨石陨石和科学频道的获奖热播剧陨石男子明星杰夫Notkin,写了明确的指南寻找太空岩石。 陨石狩猎:如何找到空间的宝物可以网上订购,或直接从我们这里。 This groundbreaking book is packed with color photographs, maps and diagrams, and also contains an excellent section on meteorite identification.这一开创性的著作是挤满了彩色照片,地图和图表,并还包含一个优秀的部分陨石鉴定。

"Will I have a better chance of finding a meteorite the day after a meteor shower?" “我有一个更好的机会发现的陨石流星雨之后一天呢?
Meteorites are not associated with annual meteor showers such as the Perseids and the Leonids.陨石是不相关的年度流星雨,如英仙座流星雨和狮子座流星雨。 The cosmic material which causes those shooting stars is cometary debris — small pieces of ice and rock, frozen and drifting in space, which burn up when they encounter our atmosphere.宇宙的物质,从​​而导致这些流星是彗星碎片 - 由冰和岩石,小块冷冻和在太空中漂流,烧了起来,当他们遇到我们的大气层。 There has never been a documented case of a meteorite being part of one of the annual meteor showers.从未有过记载的情况下的一个陨石每年的流星雨之一。

"If a meteorite hit my house, shed, barn, etc will it burn it down?" “如果一块陨石击中了我的房子,棚,谷仓,等它烧了 ?“
Despite what we see in Hollywood action movies meteorites are not burning, or even hot when they land upon the Earth.尽管我们在好莱坞动作电影陨石中看到的不燃烧,甚至热当他们在地上的土地。 The glowing fireballs we see in the night sky are caused by atmospheric pressure and friction.我们看到在夜空中发光的火球是由大气压力和摩擦。 Meteors stop ablating (burning) approximately seven miles above our planet's surface, then fall in what is known as "dark flight," according to the normal pull of gravity.流星停止烧蚀(燃烧)约7英里以上我们这个星球的表面,然后下降,被称为“黑暗飞行”,按照正常的重力拉。 It is very cold at an altitude of seven miles, so meteorites cool quickly as they plummet towards the Earth.这是在七英里的高空非常寒冷,所以陨石凉爽快速暴跌对地球。 There has never been a documented case of a burning, or even hot, meteorite landing upon the Earth.从未有过的燃烧的记录,甚至热后,地球的陨石降落的情况下。 If you witnessed a burning object hit the ground it may have been a damaged aircraft, fireworks, UFO, or other unknown object.如果你亲眼目睹燃烧的物体砸在地面上,它可能已被损坏的飞机,烟花爆竹,飞碟,或其他不明物体。

"I saw a burning fireball land. How do I find it?" “我看到一个燃烧的火球土地,我该如何找到它?
Due to their great brightness large meteors often create a remarkable optical illusion in which it appears that they have hit the ground somewhere nearby.由于他们的伟大的大流星亮度往往创造它看来,他们砸在地面上的某处附近的一个显着的光学错觉。 The glowing fireballs we see in the night sky are caused by atmospheric pressure and friction, but meteors我们看到在夜空中发光的火球所造成的大气压力和摩擦,但流星 stop ablating (burning) approximately seven miles high.停止烧蚀(燃烧),高约七英里。 If you are lucky enough to witness a bright fireball, and the flame goes out while it's directly overhead , it is possible that the meteorite will land nearby.如果您有幸看到一个明亮的火球,火焰熄灭,而它的直接开销 ,这是可能的陨石,将附近的土地。 When we see a bright shooting star apparently landing close by, what we are usually seeing is a fireball arcing away, over the horizon, still high up in the atmosphere.当我们看到一个明亮的流星 ,显然登陆关闭,我们通常看到的是一个火球电弧离开,在地平线上,仍然很高,在大气中。 Due to the curvature of the Earth, the fireball may seem to hit the ground, but has in fact just moved out of our field of view and gone beyond the horizon.由于地球的曲率,似乎火球砸在地上,但实际上只是搬出了我们的视野和超越地平线了。 Because of its extreme brightness the fireball appears — to our human eyes — to be much closer than it actually is.由于其极端的亮度的火球出现 - 我们人类的眼睛 - 比它实际上是非常接近。 It's something I, myself, have been fortunate enough to witness a couple of times and it's frustrating because it does look as if the meteorite landed "just over there."这件事情我自己,已有幸见证了几次,这是令人沮丧,因为它看起来像陨石降落“就在那边。” However, it probably landed hundreds of miles away due to the incredible speed of travel.但是,它可能由于旅行的令人难以置信的速度降落数百英里远。 Another thing to consider is that when a meteorite lands near observers, those witnesses report hearing loud sonic booms, and/or "whizzing" noises.另一个要考虑的是,当陨石落在附近的观察员,这些证人报告的听证会大声声震,和/或“嗖嗖”的噪音。 If no sound accompanied the spectacle, then the meteor was probably a great distance away.如果没有的声音伴随着眼镜,然后流星可能是一个很大的距离。 But at least you had the privilege of witnessing a real fireball!但至少你曾有幸目睹了真正的火球! If you did hear the noise phenomena that accompany a meteorite, congratulations you are one of the lucky few!如果你没有听到噪音现象,伴随着陨石,恭喜你,是少数幸运者之一! We are unable to go on new expeditions at this time but we can offer you metal detectors and rare earth magnets to assist you in starting your own meteorite hunt.我们不能在这个时候去新的探险,但我们可以为您提供金属探测器和稀土磁铁,以协助您在开始自己的陨石追捕。

"I found one of those rare meteorites that doesn't stick to a magnet" “我发现了一个罕见的陨石不沾磁铁”
Unfortunately, that is not likely.不幸的是,这是不可能的。 Even the most experienced meteorite hunters who have found hundreds of specimens hardly ever find one of those rare meteorites which is not attracted to a magnet.即使是经验最丰富的陨石发现数百个标本猎人未落发现罕见的陨石,这不是一块磁铁吸引之一。 The few meteorites that are not attracted to magnets look much like earth rocks and the majority of those have been found because it was a witnessed fall.那些没有吸引到磁铁的几个陨石看起来更像地球岩石,其中绝大部分已被发现,因为它是一个见证秋天。 If you've found a shiny metallic-looking rock that doesn't stick to a magnet, it's not a meteorite.如果您发现了一个闪亮的金属外观,不沾磁铁的岩石,它不是一个陨石。 The earth rock most commonly mistaken for a meteorite is hematite, a common iron oxide which has a bubbly red, gray, or black metallic surface, and is sometimes called a kidney stone.最常用的误认为是陨石的地球岩石是赤铁矿,一个共同的香槟红,灰,黑色金属表面的氧化铁,有时也被称为肾结石。 Please see "Streak Test" below for more information about identifying hematite.请参阅“数测试”,确定赤铁矿的更多信息下面。 If you think you have found a rare lunar meteorite, unless it has fusion crust, please do not send it in to us for identification.如果你认为你已经发现了一个罕见的月球陨石,除非它有熔壳,请不发送到我们​​的识别。 Please see the Washington University in St. Louis web site on lunar meteorite identification.请参阅在圣路易斯网站的华盛顿大学月球陨石鉴定。

"I found a rock in my field/driveway/yard and it wasn't there before" “我发现在我的领域/车道/码的一块石头,这是以前没有的
Many people contact us after finding a rock which has materialized on a lawn or driveway during the night.许多人接触后,我们发现一个草坪上或在夜间车道物化的岩石。 I agree this is an intriguing mystery.我同意这是一个耐人寻味的神秘。 Please remember not all strange rocks are automatically meteorites.请记住不是所有的奇石怪自动陨石。 Please perform some of the tests described below to find out more about your rock.请执行下文所述的测试,找出岩石。

"I found a strange rock in the ocean/in a riverbed/near the railroad tracks" “我发现一个奇怪的石头在河床附近的铁轨/海洋/”
As we now know, meteorites contain iron and iron decomposes in moist environments or near water, especially salt water.正如我们现在知道,陨石含有铁和铁分解,在潮湿的环境或靠近水的地方,特别是盐水。 It is therefore very unlikely that a meteorite would be found in or near the ocean or a riverbed, although meteorites have occasionally been found in dry washes in the desert.因此,它是不太可能的陨石将在或接近海洋或河床发现,虽然偶尔在沙漠中的干洗发现的陨石。 Man-made material that will stick to a magnet is often used in the construction of railroad lines and that material is usually black in color.人造材料,将继续坚持一个磁铁往往是在铁路线的建设和使用材料通常是黑色的。 If your rock was found on or near a railroad line, it's not a good sign.如果您的岩石上或附近的铁路线,这不是一个好兆头。

"I found a heavy piece of metal that is round and looks like a cannon ball" “我发现了一个沉重的一块是圆的金属,看起来像大炮球
I have never seen a perfectly round meteorite.我从来没有见过一个完美的圆形的陨石。 If your piece of iron looks perfectly spherical, you can be pretty sure it was made by a person, even if it looks old and has acquired a patina.如果你的铁片看起来完美的球形,你可以确信,它是由一个人,即使它看起来老,并已获得了铜锈。 Man-made objects are found in odd and unexpected places.在奇数和意想不到的地方发现的人造物体。 Settlements are sometimes abandoned and metallic items get left behind.有时放弃住区和金属物品被甩在后面。 19th-Century prospectors ranged all over the world, especially in the American West, looking for precious metals. 19世纪的探矿范围遍布世界各地,尤其是在美国西部,寻找贵金属。 They often left lumps of smelted metal ore behind them, and that material is frequently mistaken for meteorites.他们往往留下肿块,在他们身后的冶炼金属矿和材料是经常误为陨石。 Also, people drop things, forget things, and throw things away.此外,人降的事情,忘事,并抛出东西。 Man-made metallic objects are everywhere.人造金属物体到处都是。

"How much is my meteorite worth?" “多少钱是我的陨石值得吗 ?“
Asking how much a meteorite is worth is like asking how much a diamond or a car is worth.问多少的陨石是值得的,就像是问多少的钻石或汽车是值得。 Value is determined by many factors including rarity of type, size, condition, aesthetic appeal, and so on.值是由许多因素,包括罕见的类型,规模,条件,审美情趣等。 Despite what you may have heard on television, or read on the internet, your meteorite is probably not worth a million dollars.尽管你可能听说过在电视上,或在互联网上阅读,您的陨石可能是不值得一百万美元。 However, meteorites are valuable to collectors and researchers.然而,陨石是有价值的收藏家和研究者。 Last year we identified a rock found in a field in the Midwest as a genuine meteorite and valued it at over $50,000.去年,我们确定了作为一个真正的陨石在中西部地区的一个字段中发现一块石头,价值超过50,000元。 If we determine that you have a genuine meteorite, we can then estimate its value for you.如果我们确定你有一个真正的陨石,然后我们可以为您估计其价值。

 

 

 

      
METEOR-WRONGS 流星的是非曲直
Please study carefully! 请仔细研究! All of these are common Earth rocks which are certainly look unusual, but not meteorites. 所有这些都是共同的地球岩石,这当然是看不寻常的,但不是陨石。 We know it can be difficult to someone outside the profession to distinguish a meteorite from a meteor-wrong, that is why we offer this page as assistance and an inspection service for a nominal fee. 我们知道以外的专业的人可能很难区别于流星错误的陨石,这就是为什么我们提供的援助和检查服务仅象征性收费

THE TESTS 测试
How to determine if you have a genuine meteorite 如何确定如果你有一个真正的陨石

1) Visual Inspection 1)目视检查
If you've read the previous passages you now know much more about meteorites than the average person.如果你读过前面的通道,你现在知道比一般人更多有关陨石。 Congratulations, and thank you for reading this far.表示祝贺,并感谢您阅读本。 Now, please carefully consider the following: Does your rock exhibit any of the characteristics discussed above?现在,请慎重考虑以下:你的岩石展示上面所讨论的任何特点? Does it feel heavier than it should?是否感觉比它应该重呢? Does it have regmaglypts, or patina, or fusion crust?它是否有regmaglypts,或铜绿,或熔壳? Compare your rock to the photographs of real meteorites, and meteor-wrongs.比较你的摇滚真正的陨石的照片,和流星的是非曲直。

2) The Magnet Test 2)磁铁测试
Please remember, a meteorite will stick easily to a good magnet. If your rock does not adhere to a powerful magnet you almost certainly do not have a meteorite.请记住, 一块陨石将坚持一个很好的磁铁 ,如果你的摇滚不坚持一个强大的磁铁,你几乎肯定不会有陨石。 There are many Earth rocks that also stick to magnets, so if your specimen adheres to a magnet it is not automatically a meteorite, but it's a step in the right direction.有许多地球岩石,还坚持磁铁,所以如果你的标本坚持一个磁铁,它不会自动一块陨石,但它是朝着正确方向迈出的一步。

3) The Streak Test 3)连胜测试
Iron oxides like hematite and magnetite are the Earth rocks most frequently mistaken for meteorites.铁的氧化物,如赤铁矿和磁铁矿是地球最频繁误陨石的岩石。 They are moderately heavy (not nearly as heavy as iron meteorites) and appear metallic in composition.他们中度重(不如沉重的铁陨石),并出现在组成金属。 Some specimens will stick to a magnet.部分标本将继续坚持一个磁铁。 If you think you have an iron meteorite, here's an easy test you can perform at home: Take your rock sample and scrape it against the coarse (unglazed) face of a white bathroom tile, just like you were drawing on a blackboard with a piece of chalk.如果你觉得你一个铁陨石,这里的一个很容易的测试可以在家执行:以您的岩石样本,并刮去反对的一个白色浴室瓷砖粗(无釉)面对它,就像你是在黑板上绘制了一块粉笔。 If your rock leaves a reddish or rust-colored streak on the tile it is likely hematite.如果您的岩石留下了红色或铁锈色的瓷砖连胜,这是可能的赤铁矿。 If it leaves a dark gray streak it is likely magnetite.如果它留下了暗灰色条纹,它是可能的磁铁矿。 This test only works on iron meteorites (not stones).此测试仅适用于铁陨石(不是石头)。 A genuine iron meteorite will typically leave NO STREAK, or possibly a very faint grayish mark.一个真正的铁陨石,通常会留下条纹,或可能是一个非常微弱的灰白色标记。 Please note that the streak test only works on iron meteorites.请注意,连胜测试只铁陨石。

4) The Nickel Test 4)镍测试
Most meteorites contain a significant percentage of nickel and iron.大多数陨石含有镍和铁的显著的比例。 Naturally occurring Earth rocks do not, so if your specimen tests positive for nickel it may be a meteorite.自然发生的地球岩石不这样做,因此,如果您的标本测试呈阳性反应,对镍,它可能是一个陨石。 We do not use or recommend store bought nickel testing kits.我们不使用或推荐商店买镍检测试剂盒。 In our experience they have not been effective in testing for meteoric nickel.在我们的经验,他们没有被有效地测试流星镍。 A professional analysis from an assay lab is the best method to use in order to determine nickel content.从专业分析检测实验室,是最好的方法使用,以确定镍含量。
