放射性

This approach seemed to work: radiocarbon dating of Taino posts has shown that they were in place for hundreds of years.

从考古证据看，这一推论应该是正确的：放射性同位素测定表明，那里的柱子已在原位牢牢竖立了好几百年，而更重要的是，那些木桩的树皮还好好的。

Researchers use radiocarbon to study certain biological processes.

研究人员借助放射性碳来研究某些生物过程。

To resolve this issue, the Coronerordered radiocarbon and DNA analyses.

为确定最终结果，验尸官会安排放射性C14检测和DNA分析。

The process, sometimes referred to as "radiocarbon reading," involves measuring carbon decay.

过程中，有时称为"放射性碳含量，"碳涉及测量衰变。

The site was dated back to 5200 B.C., in the Late Stone Age, through radiocarbon dating.

这个遗址可以追溯到公元前5200年，石器时代后期，经理了放射性碳的时代。

The results show that the explosion of Supernova SN1054 had caused increase of radiocarbon contents Δ14C in tree rings.

从测量结果可看出超新星SN1054的爆发引起了树轮放射性碳含量Δ14C的增加。

We took part in the Fourth International Radiocarbon Inter comparison study as the one and only lab from China to participate.

中国科学院地球环境研究所14C实验室作为中国唯一的代表参加了第四届放射性碳测年国际比对活动，取得了比较优异的成绩。

To do this we have included 183 volcanoes with dated eruptions during the last 10,000 years, as determined by techniques such as "Radiocarbon" dating.

为了做到这一点，我们把183座在过去10000年内有爆发日期的火山包括了进去，这是用"放射性碳元素"日期测定技术来决定的。

The split between the two groups can hardly be papered over.
