- 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。
- 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。
- 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。
- The results agree with those by using isotopic method reported in the literature. 与文献报道的同位素方法研究结果相同。
- After my colleagues and I had worked out in a general way how the observed set of xenon isotopes was created inside the aluminum phosphate grains, we attempted to model the process mathematically. 在想通了观察到的氙同位素大致如何在磷酸铝颗粒中生成之后,我和同事就试图用数学模式来模拟这个过程。
- But even if nature could miraculously create a similar process on a microscopic scale, the mix of xenon isotopes in the aluminum phosphate grains we studied would have been different from what we found. 但是,即使大自然能奇迹似的在微小尺度创造出类似的过程,磷酸铝颗粒中的氙同位素组成也会和我们所发现的不同。
- The method seems good but it needs to be tried out. 这个方法似乎不错,但需要试验一下。
