陨石

Or are they being formed as a result of meteoroids or sunlight hitting the surface?

或者，它们是因为陨石撞击或阳光照射表面而产生的结果？

As you saw, I wasn't able to stop all the meteors.

正如你所见，我未能阻止全部陨石。

I tried to stop the largest meteors from striking outside the city, but a few got away from me.

我试着从高空阻止最大的陨石撞击城市，但却有一些从我身边漏掉了。

Here we present a simple alternative explanation involving deposition from a ground-hugging turbulent flow of rock fragments, salts, sulphides, brines and ice produced by meteorite impact.

在这里我们提供一种简单的替代方案解释下面现象包括来自地面的沉淀-包裹岩石碎片，盐，硫化物，盐水和被陨石冲击生产的冰叶的流程。

Now two NASA scientists studying meteorites older than our planet have found a majority of left-handed amino acids, suggesting that our solar system has always had a preference for southpaws.

现在两个美国航空航天局的科学家在研究比地球更久历史的陨石的时候，发现了大部分的左旋氨基酸，这表明我们的太阳系一直钟情于左撇子。

The study of natural fullerenes is a new area of across fullerene science and geological science. So far natural fullerenes have been found in shungite, fulgurite, carbonaceous conglomerates in impact crater, E/K boundary carbonrich clay rock layer, T/P boundary layer, dinosaur eggshell, coal, heavy crude oil, solid bitumen and socalled seminatural fullerenes in common soots, Chinese ink sticks, commercial char, et al., only with low concentrations.

天然富勒烯研究是富勒烯科学和地质科学相交叉的一个新兴研究领域，迄今为止已在桑加岩、闪电熔岩、陨石撞击坑中的含碳质角砾岩、古近系/白垩系地层界线的含碳粘土岩、三叠系/二叠系界线岩石、恐龙蛋壳、煤、重质油、固体沥青以及半天然的烟灰、木炭、书墨等物质中检测到富勒烯的存在，但含量很低。

Among the Stardust particles, the investigators found that the ratio of oxygen isotopes was similar to that found in meteorites formed in the inner solar system.

调查人员发现在星尘样品中氧同位素的比例与形成与太阳系中心的陨石类似。

The pea-sized piece of rock hit him in the hand, sent him flying, and then buried itself in the road.

豌豆大小的陨石打在他的手上。把他撞飞，之后就掉在路上。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
