铁陨石

The outer, non-metallic layers of the planet form what are known as achondrite stony meteorites, and there is a separate class of stony-irons that come from the boundary between inner core and outer layer.

位于行星外部的非金属层形成无球粒陨石石质陨石，在内核和外层之间还存在有一层独立的石质铁层。

The abundances of siderophile element Fe, Co, Ni, Au are close to those in Allende and CV chondrite, Na is slightly enriched and Mn,Cu show depletion.

亲铁元素Fe、Co、Ni、Au的丰度与Allende和CV陨石相应丰度接近，而Na略有富集，Mn、Cu显示出贫化的特征。

Meteorolite, very pure iron, so we can expect gold from sky.siderite, with crytles

陨石，真的，天上掉下来的都是这样的铁块，可以期待掉金子，馅饼有点难。

Troilite, rare on earth but a common mineral found in meteorites, was synthesized by arc-discharge method for the first time.

首次用电弧放电法合成出在地壳中罕见而在陨石中却常见的矿物——陨硫铁。

It may be the third largest iron meteorite in China. Fe content is 94.02%, Ni content 5.29%, and Co 0.45% in the iron meteorite. The main mineral is kamacite, and crystal and aggregate of schreibersite were also found in the iron meteorite.

通过初步的化学分析和矿物学分析，发现其铁含量为94.02%，镍含量为5.29%，钴含量为0.45%，主要矿物为铁纹石，局部含有陨磷铁镍石的晶体或集合体，表明它是一块典型的铁陨石。

Of mesosiderite. Current models of formation of mesosiderite are mainly based on mineralogy and movement of planetisimals, constraints from geochemistry are limited.

现有的中铁陨石形成和演化的模型的提出和论证基本上都基于其动力学机制和矿物组合的考虑，较少从矿物相之间的地球化学关系和制约上进行探讨。

Major element abundances of the silicate phase of the two mesosiderites are similar to those of howardites. The cosmic ray exposure ages are (242± 50) Ma for Dong Ujimqin Qi mesosiderite and (25.4± 5.0) Ma for Weiyuan mesosiderite.

东乌珠穆沁旗及渭源中铁陨石的硅酸盐相在主元素丰度上类似于紫苏钙长无球粒陨石，其宇宙射线暴露年龄分别为(252±50)Ma和(25.9±5.0)Ma。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
