陨石的

Meteorites arriving on Earth are decelerated by passing through our atmosphere.

到达地球的陨石经过我们的大气层时速度会降低。

The Moon's heavily cratered surface is the result of intense pummelling by space rocks between 4.1 and 3.8 billion years ago.

月球表面遍布的环形山是由41亿年到38亿年前太空陨石剧烈撞击月球而形成的。

On the second floor, mammals are exhibited, what are more fantastic are Africa tropical grassland animals and Australia marsupial animals; on the right side, minerals, rocks and precious stones are exhibited and there is also special show room for aerolites.

二层左侧展出哺乳动物，其中较精彩的是非洲热带草原动物和澳大利亚有袋动物的陈列；右侧陈列矿物、岩石、宝石，并有专室陈列陨石。

However, tellurium contents are extrmely high in Co-rich crusts, marine polymetallic nodules,deep-sea sediments and aerolites.

中文摘要：碲在地球上是一种稀有分散元素，碲在地壳中的丰度很低，仅为1.0ng/g；但碲在富钴结壳、海底多金属结核、党海沉积物和陨石中的丰度异常高。

Or arrived as part of a late-accreting veneer of water-rich meteorites, similar to the carbonaceous chondrites that we see today

另一种是来自一种后期聚集增生的富水陨星块体，与今天看到的碳质陨石相似

Looking at these isotopes allows the chondrules to be dated, and they were formed 4.56 billion years ago.

观察这些同位素可以估算出陨石球粒的年龄，他们是在45.6亿年前形成的。

Once a merged mass of chondrules and dust got big enough, things started to happen.

一旦陨石球粒和灰尘聚合的数量变的足够大，有些事情开始发生了。

Chondrules are frozen droplets of once-liquid rock.

陨石球粒是由一些曾经液化的石头凝固而成的小滴。

So meteorites are tangible evidence of what was happening when the solar system was born.

因此，陨石为研究太阳系诞生时的情况提供了切实的证据。

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。
