" A problem I've been advertising as an isotopic crisis."

“我一直在宣传一个问题是危机。”

Ask a pair of geochemists how something like this works, and they will start talking about isotopic abundances and ionization levels with an enthusiasm that is more endearing than fathomable.

要是你问两地球化学家这工作是怎么进行，他们会滔滔不绝地谈到丰富、离子化程度，等等，这些听上去很可爱，但不容易搞明白。

This is the isotopic composition of the animal's bones and teeth Hydrogen apart.

这是动物骨骼和牙组成，氢除外。

So to determine how much of the stuff was truly interstellar—from beyond our solar system—the researchers used other isotopic clues to screen out quantities of iron-60 produced by nuclear reactions and cosmic rays.

因此，为了确定有多物质是真正星际物质——来自我们太阳系之外——研究人员使用其他线索来筛选核反应和宇宙射线产生铁 60 数量。

Now, he says, a new theory in the journal Nature Geoscience may at least point to a way out of that isotopic crisis of the moon's chemical isotopes so closely resembling Earth's.

现在， 他说，《自然地球科学》杂志上一项新理论可能至指出了解决月球化学与地球非常相似危机方法。

By comparing the isotopic composition of the particles Stardust collected  with samples from our own solar system, it was proven that Comet Wild 2 originated from the solar  system.

通过比较“星尘号” 采集颗粒成分与太阳系内样本，证实了维尔德2号彗星起源于太阳系。

But more recent, detailed studies which analyse the isotopic data in more detail have pushed the consensus away from farming and rubbish dumps and towards swamps.

但最近对数据进行更详细分析详细研究已将共识从农业和垃圾场转向沼泽。

So if someone moves from one place to another, bones synthesized after that move will also reflect the new isotopic signatures of the surrounding environment.

因此， 若有人从一个地方迁移到另一个地方，迁移后合成骨骼也将反映出新环境周围特征。

The only way maybe you could tell is by looking at the isotopic strata to see if there was anything reminiscent of an industrial civilization.

也许唯一能判断方法是通过观察层来查看是否有任何类似于工业文明痕迹。

In addition, the lunar rock samples show similar isotopic signatures to terrestrial rocks, unlike those found on Mars or elsewhere in the solar system.

此外，月球岩石样本显示出与地球岩石相似特征，这与火星或太阳系其他地方发现岩石不。

The research is interest was in the isotopic ratios in the teeth under investigation of two chemical elements oxygen and strontium Atomic nuclei are made of protons and neutrons known collectively as nucleons.

研究兴趣在于被调查牙两种化学元——氧和锶比率。原子核由质子和子组成，统称为核子。

Problem is, as scientists have taken more and more precise isotopic measurements of the Moon they've found that it's nearly identical in composition to the Earth—not some other object.

问题是，随着科学家们对月球进行越来越精确测量，他们发现月球成分几乎与地球相，而不是其他物体。

By  examining the isotopic composition, scientists would be able to tell if it was unusual when  compared to the dust given off by our own star.

通过检查组成，科学家们将能够判断它与我们自己恒星发出尘埃相比是否异常。

By comparing the isotopic composition of the  particles Stardust collected with samples from our own solar system, it was proven that  Comet Wild 2 originated from the solar system.

通过比较收集到星尘粒子与太阳系样本组成，证明维尔德 2 号彗星起源于太阳系。
