陨石球粒

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 large number of meteorites from Antarctica and the desert areas of Australia,Africa and North America changed the previous chondrite classification in recent years.

近年来在南极及澳大利亚、非洲和北美的沙漠地区发现和回收了大量的陨石，改变了以前的球粒陨石分类。

An ordinary chondrite(Sample No.GRV052483) was recovered on blue ice during the 22nd Chinese Antarctic Research Exploration in Grove Mountains,Antarctica.

南极陨石GRV052483样品为中国第22次南极科学考察队在蓝冰上发现的一块普通球粒陨石。

The elemental weight ratios (Na, K, Mg, Ca, Fe, Al, Ti, Mn, Ni)/Si of Ningqiang matrix are within the range of the corresponding ratios of CV chondrite matrix, Ca/Si and Al/Si ratios are high relative to those in the other CV chondrite matrix.

宁强基质的元素重量比值（Na、K、Mg、Ca、Fe、Al、Ti、Mn、Ni）/Si处于CV球粒陨石相应比值的变化范围之内，而Ca/Si、Al/Si值相对于其它CV陨石基质的同样比值较高。

According to this scenario, researchers could never find evidence of such early chondrules because all these objects would have been destroyed by the melting of the chondritic asteroids into which they accreted.

在这个情形下，研究人员恐怕永远也无法找到如此早期的球粒证据，因为所有这些物体在聚合的过程中，都会因为球粒陨石小行星熔化而被破坏。

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。

Irons, stony-irons, chondrites, and achondrites are by no means equally abundant among observed meteorites.

铁矿、陨铁石、球粒状陨石及无球粒陨石在可观测到的陨石中绝不多见。

The study and comprehensive analysis of static high-pressure quenching experiments and laboratory dynamic high-pressure experiments on chondrites,as well as the study of shock-induced phase transition of minerals in the Suizhou meteorite revealed that the P-T conditions for phase transition of minerals during natural impact events,such as collision of cosmic bodies or impact of meteorites on the Earth′s surface,are not consistent with those obtained by shock experiments on chondrites or rocks in laboratory,...

通过对球粒陨石的静态高压淬火实验和人工动态高压实验的研究和综合分析，以及对在太空中经受过撞击的随州陨石中矿物发生高压相变的研究，查明了自然界的冲击事件，如星体的相互碰撞和陨石对地球表面的撞击中，矿物发生相变的P-T条件与人工冲击波实验的结果并不一致，而与静态高压淬火实验的结果相似，即前者类似静态高压淬火实验，保压时间较长，能产生高压矿物，后者保压时间极短，无高压矿物形成。

铁矿、陨铁石、球粒状陨石及无球粒陨石在可观测到的陨石中绝不多见。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
