陨石的

Among the investigated meteorites, Dong Ujimqin Qi, Weiyuan mesosiderites and Ningbo iron meteorite were recovered in China, and Rafruti ataxite was found in 1886 in Switzerland.

在所研究的4个陨石中，东乌珠穆沁旗、渭源{类型Ⅲ中铁陨石及宁波铁陨石是在中国回收的，另一个无结构铁陨石Rafruti是于1886年在瑞土发现的。

Classification of ordinary chondrite s based on mean Fa and Fs value of olivine and Low-Ca pyroxene respectively is effective.

格罗夫山普通球粒陨石在类型分布上，其比例和南极以及非南极普通球粒陨石有显著不同，说明可能存在相当数量的成对陨石。

In addition to the established groups,there are about ten unique chondrites or chondrite grouplets, and also numerous ungrouped irons and iron grouplets.

此外 ，还发现1 0个独特的球粒陨石、许多未分群的球粒陨石小群、铁陨石和铁陨石小群，它们也来自各自不同的母体。

The enstitate ordinary chondrite family formed near the Sun and in the inner solar system.

Two types of olivine in the Dongujimqin mesosiderite were identified: the matrix olivine and the brecciform olivine.

东乌珠穆沁旗中铁陨石中有二种橄榄石。一种是陨石中基质橄榄石，另一种是镶嵌在陨石表面的角砾状橄榄石。

The work involves two of the seven known "nakhlite" meteorites (named after El Nakhla, Egypt, where the first such meteorite was discovered), and the celebrated ALH84001 meteorite that some scientists believe shows evidence of microbial activity on Mars.

他们研究了七个知名的透辉橄无球粒陨石（根据陨石第一次被发现的地名命名，在埃及的 El Nakhla）中的两个和著名的ALH84001陨石（一些科学家认为这颗陨石反映了火星上的微生物活动）。

Two special TL phenomena have been found in Yanzhuang meteorite through the determination of the natural TL, annealed TL and induced TL by β radiation: l.when the sample of Yanzhuang meteorite is annealed at temperature up to 500℃, the TL peak induced by β rays moves to lower temperature with the increasing of irradiation dose; 2.when the annealed temperature is greater than 600℃, the TL peak temperature of the annealed sample is higher than that of the unannealed sample.

991年10月31日21点45分在广东省翁源县岩庄乡境内发生了陨石降落。从降落现场收集到3.skg的陨石样品，经初步鉴定为H6型、具有强冲击变质特性的珍稀普通球粒陨石。根据陨石命名规则定名为岩庄陨石。普通球粒陨石是目前研究太阳系早期所发生的化学与物理变化过程的最好的信息来源。

The chemical-petrographic types of these meteorites are presented below.Six are unequilibrated ordinary chondrites,including three H3 and three L3;92 meteorites are equilibrated ordinary chondrites,including 24 H-group(13 H4,10 H5,1 H6),64 L-group(2 L4,44 L5,18 L6) and 4 LL-group(3 LL4,1 LL5);the other two belong to stone-iron meteorites.In 6 unequilibrated ordinary chondrites,chondrules are well-shaped,and olivine and low-Ca pyroxene are commonly zoned and have wide ranges of composition.The olivine and low-Ca pyroxene in the other 92 equilibrated ordinary chondrites have similar composition,respectively,and to some degree it reflected thermodynamics equilibration in olivine and lowCa pyroxene.

并根据矿物-岩石学特征，划分了它们的化学-岩石类型：6块属于非平衡型普通球粒陨石(H3和L3群各3块)；92块属于平衡型普通球粒陨石，包括：H群24块(13块H4，10块H5，1块H6)，L群64块(2块L4，44块L5，18块L6)，LL群4块(3块LL4，1块LL5)；另外两块属于石-铁陨石。6块非平衡型普通球粒陨石保存了原始的岩石学和矿物化学特征，包括：清晰的球粒结构、橄榄石和低钙辉石具有明显的成分环带以及极不均一的化学组成等。92块平衡型普通球粒陨石中的橄榄石和低钙辉石显示出均一的化学组成，表明它们达到了一定的热力学平衡。

According to bulk chemistry, the ungrouped GRV 98003 is classified into IAB group, and the ungrouped Ujimqin as a unique iron of IAB iron meteorite complex.

根据化学组成，重新对这两个未分群的铁陨石进行了分类工作，其中将GRV98003铁陨石划分为IAB群，乌珠穆沁铁陨石划分为与IAB群相关的单独铁陨石。

Of a total of 28 meteorites collected in Grove Mountains, Antarctica, by the 16th CHIN-ARE, there are 20 equilibrated ordinary chondrites.

我国第16次南极科考队回收的28块陨石中，除1块火星陨石、1块HED陨石和6块非平衡L3型陨石外，其余20块为平衡型普通球粒陨石。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
