An experimental sampler for rare gases (ESRG) which can collect radioxenon isotopes from atmosphere under normal temperature and low temperature is installed and studied.
为了在常温至低温条件下进行大气中氙同位素取样,研制了一套稀有气体取样实验装置(ExperimentalSamplerforRareGases,RSRG),并以129Xe为分析对象,利用感应耦合等离子体质谱仪进行了取样效率标定。
Currently the most important difficulties are xenon sampling, puring and radioactive xenon isotopes measuring.
测量放射性氙同位素活度一般采用HPGeγ能谱法或β-γ符合法,本文详细介绍了这两种方法测量惰性气体氙同位素的原理和方法,实验室同时用两种方法测量了CTBT组织的IMS(国际监测系统)2007年度和2008年度惰性气体传递实验氙样品,对两种方法的测量结果进行了分析,并提出了提高惰性气体氙样品测量准确度的方法。
The result was the peculiar segregation of xenon isotopes we uncovered.
结果就是我们所观察到，氙同位素的特殊区隔。

However, some of the minerals contain xenon isotopes unlike those usually produced by radioactive decay of uranium.
然而，有些含氙同位素的矿物并非如此，是由铀的放射性衰变产生的。
None of the xenon isotopes we measured were the direct result of uranium fission.
我们所测量到的氙同位素，根本都不是直接由铀的核分裂而来。
This exercise revealed much about the timing of reactor operation, with all xenon isotopes providing pretty much the same answer.
这个计算揭露了许多关于反应器运作时间的细节，而所有氙同位素都提供大致相同的答案。
Another mystery is the isotopic composition of xenon found in minerals from the Oklo uranium deposit in Gabon, Africa.
另一个令人费解的问题就是在非洲加蓬的奥克洛铀矿床的矿物中所发现的氙同位素组成。
As expected, the researchers found the xenon isotope produced by uranium fission in uranium minerals from this deposit.
正如所预料的那样，研究人员发现氙同位素是由这些沉积矿床中的铀矿物裂变产生的。
An hour later the next lighter stable isotope, xenon 134, appeared.
一小时之后，略轻一点的稳定同位素氙134出现。
Xenon possesses nine stable isotopes, produced in various proportions by different nuclear processes.
氙具有九种稳定的同位素，在不同的核反应中所产生的比例不同。
Being a noble gas, it resists chemical bonding with other elements and is thus easy to purify for isotopic analysis.
由于氙是惰性的，不易与其他元素产生化学键，因此很容易纯化以进行同位素分析。
