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

“我一直在宣传一个问题是同位素危机。”

2.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.

所以如果有人从一个地方 迁移到另一个地方，在迁移后合成骨骼会同样反映出有关 周围环境新同位素标志。

3.Its chemistry, pristine because of the Wilcocks' swift action, showed that the water in it nevertheless had the same isotopic composition as water on Earth.

由于威尔科迅速行动，它化学成分是原始，表明其中水与地球上水具有相同同位素组成。机翻

4.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.

但最近对同位素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。机翻

5.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.

通过检查同位素组成，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。机翻

6.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.

要是你问两位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同位素、离子化程度，等等，这些听上去很可爱，但不容易搞明白。

7.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同位素测量，他们发现月球成分几乎与地球相同，而不是其他物体。机翻

8.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同位素组成，证明维尔德 2 号彗星起源于太阳系。机翻

9.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少指出了解决月球化学同位素与地球非常相似同位素危机方法。机翻

10.This, by studying the isotopic composition of ancient silver coins, has tried to draw conclusions about where the metal in a coin was mined, and thus about patterns of trade.

这通过研究古代银币同位素组成，试图得出关于硬币中金属是在哪里开采结论，从而得出关于贸易模式结论。机翻

11.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，为了确定有多少物质是真正星际物质——来自我们太阳系之外——研究人员使用其他同位素线索来筛选核反应和宇宙射线产生铁 60 数量。机翻
