陨石

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。

At first it was thought to be a meteor impact crater due to its circularity but this has since been disproven due to the lack of shock-altered rock in its vicinity.

首先他被认为是一个陨石撞击而产生的陨石坑，因为它呈现的是一个圆的形状；但是这个说法已经被推翻，因为它的坑内附近缺乏陨石撞击会产生的变质岩石(shock-altered rock)。

Observations by laser confocal microscope and determinations by electron probe revealed that neither carbonaceous chondrite nor enstatite chondrite were found among these meteorites.

经激光共聚焦显微镜观察，未查出碳质球粒陨石。经电子探针鉴定，也未发现顽火辉石球粒陨石。

When meteorite hit the Earth surface, it created shockwave to transfer the kinetic energy to the Earth surface. When the speed of meteorite strike reached 10 km/second, the pressure of shockwave can reach several millions bar to compress the target terrane to produce heat, the effect of impact deformation caused by it is several scales stronger than rock intensity, the granite would melt down once the pressure of shockwave reached about 500 thousands bar, the granite would gasify (solid became liquid and meanwhile further became gaseity) once reaching over 600 thousand bar.

当陨石撞击地表时产生冲击波把陨石的动能传给地表，在陨击速度达到10公里/秒时冲击波的压力可达到数百万巴并压缩靶点岩层物质产生热，它产生的冲击变形效应比岩石强度大几个量级，冲击波压力约50万巴时花岗岩就熔化，大于60万巴时花岗岩就气化（在固态转为液态同时进一步转为气态）。

About 90% of meteorites are classified by the successors of Silliman and Kingsley as chondrites.

90%的陨石都分类为球粒状陨石。

This is one of the secrets of meteorites algorithm, named for the meteorite secret.

这是一个关于陨石的秘密的算法，名字为陨石的秘密。

Important natural geological analogues are volcanic glass and meteoric glass(anal-ogues of solidified mass), clay minerals (natural analogues of backfill material), iron meteorite and copper deposits (natural analogues of waste containers), natural nuclear reactors, uranium deposits, iron deposits containing Th and REE and contact zones between igneous rocks and other rocks (natural geochemical analogues of HLW repository).

目前已有的地质类比研究对象主要有火山玻璃，陨石玻璃，粘土矿物，铁陨石，铜矿床，铀矿床，含含Th和REE的铁矿床，天然核反应堆和火成岩接触带等。

Do not gum up the work by telling mother what we are going to do .

别告诉母亲我们要干的事，那会把事情搞糟的。

In recent years, application of the partial prestressed concrete beam s is developed.

近年来，随着部分预应力砼梁应用的推广，发现我国规范所采用的名义拉应力法的计算结果不稳定。
