查询词典 meteorite

Under the precondition of above analyses, this research compares the meteorite-stricken cases in planets and secondary planets of solar system, the "shielding" and "eroding" effect in aerosphere, the scale of small planets and movement rules, then briefly analyzes the basic reason of mass meteorite-stricken events occurred in earth history.

在上述分析的前提下，本研究从太阳系有关行星和卫星表面陨击现象对比，大气层的"遮蔽"和"侵蚀"作用，小行星的规模及运动规律等方面简要分析了地球历史上大规模陨击事件发生的基本原因。

For meteorite-stricken events in relatively large scale, the impact is so huge that it reaches the earth antipodal point of the meteorite-stricken target through the meteorite-stricken antipodal effect.

对较大规模的陨击事件来说，其影响之广甚至可通过陨击对趾效应达到陨击靶点的地球对趾点。

The ordinary chondrite Semarkona is the most unequilibrium LL3.0 type meteorite, which might be only weakly effected by later thermal metamorphism. Thus, the age of Semarkona is significantly important for the studying of the formation and evaluation of meteorite.

普通球粒陨石Semarkona是最小平衡的LL3.0型陨石，受后期热变质的影响很小，因此其年龄研究对反演陨石起源有重要意义。

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）。

This article adopts the method of comparative planetology, suggesting that meteorite-stricken event is the widespread geological process in the solar system, and the meteorite-stricken case occurred on the earth is the same as it did in other earth-like planets in the solar system.

本文采用比较行星学的方法，认为陨击作为太阳系普遍的地质过程，地球跟太阳系其他类地行星受到陨击的情况是相类似的。

This article adopts the method of comparative planetology, suggests that meteorite strike event is the universal geological process in solar system, and the meteorite strike case occurred in the earth is as the same it did in other terrestrial planets.

本文采用比较行星学的方法，认为陨击作为太阳系普遍的地质过程，地球跟太阳系其他类地行星受到陨击的情况是相类似的。

This article adopts the metho d of comparative planetology, suggests that meteorite strike event is the universal geological process in solar system, and the meteorite strike case occurred in the earth is as the same it did in other terrestrial planets.

本文采用比较行星学的方法，认为陨击作为太阳系普遍的地质过程，地球跟太阳系其他类地行星受到陨击的情况是相类似的。

Based on the theory that "meteorite strikes are a common geological process in the solar system" and the comparative planetology, these ringed mountain geological structures are the relics of earlier meteorite strikes distributed on the earth, which is the natural landscape formed in the interaction when celestial bodies fell down on the earth and struck the ground.

根据"陨击是太阳系普遍的地质过程"和比较行星学推测，这些环形山地质构造是地球上分布的早期陨击遗迹，是外天体陨落地球撞击地面岩层时与其相互作用形成的自然景观。

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。

The shockwave of the meteorite strike on the terrane of the surface passes the dynamic energy to the surface and forms the target terrane shatter cone; due to the fact that the terrane of stricken surface can not maintain the state of stress, a cluster of rarefaction wave was formed behind the shockwave to decompress terrane substances from high pressure state, this cluster of rarefaction wave ejects with high speed from the interface between the substances such as meteorite, surface terrane and lava, the shockwave compresses the target terrane substances, generating super-high temperature and forming a jet current of rock mass, rock powder, lava or rock fog with high pressure and temperature, the jet current lasted until the shockwave rebounded from the backside of rock, and the target of meteorite-stricken surface is formed on surface.

陨石撞击地面岩层时的冲击波把动能传给地表产生靶岩震裂锥，由于被撞击地表岩层不能维持应力状态，冲击波后面就发展一簇稀疏波使岩层物质从高压状态下减压，在陨石、地表岩层、熔岩等物质交界处高速喷出，冲击波压缩靶点岩层物质产生超高温，成为压力大温度高的岩块、岩粉、熔岩或岩雾喷射流，直到冲击波从岩石背侧反射、地面上形成陨击靶点。

Graf, without question, is the greatest women's player in history.

格拉芙，现在，毫无疑问是女子网坛历史上最伟大的选手。

If not, you will have to look around at all your important data.
