a chemical analysis used to determine the age of organic materials based on their content of the radioisotope carbon-14; believed to be reliable up to 40,000 years

radiocarbon dating provides a range, often spanning 200 years or more, rather than an exact date for a site.

采用放射性碳技术来测定一处考古遗址的年代，得到的并不是一个準确日期，而是一个时间跨度范围通常为200年或更久远的数值。

radiocarbon dating in 1988 by three independent teams of scientists determined that it was made during the middle ages, long after jesus lived.

so it turns out that radiocarbon dating works for a lot of prehistorical art.

所以放射性碳年代测定对许多史前艺术有用。

radiocarbon dating places the site at ca.

the team obtained the date of 9260 years ago for the coprolite by radiocarbon dating one of the prickly pear seeds inside.

研究小组用碳→14年代测定法测定一颗刺梨种子的内部，把粪化石的年代确定为9260年以前。

accordingto bunce, eggshell is the best substance for radiocarbon dating andisotope analysis, which gives information about the environment inwhich the egg was laid.

bunce称蛋壳是最适合进行放射性碳年代测定和同位素检定的物质，能够提供胚胎当时所处环境的信息。

radiocarbon dating indicates the figure excavated from an archaeological dig in southern germany, near the danube valley, was at least 35, 000 years old, the researchers said.

radiocarbon dating experts have also found advantages from working onsite with archaeologists.

放射性碳测定年代的专家们还发现了在考古现场工作的各种优点。

because they rely on estimation, relative techniques like stratigraphy are considered less precise than absolute techniques, like radiocarbon dating or verification from written records.

因为他们象地层学那样依赖相关的技术进行推测，其精确度不如用放射性碳元素断定或根据记录来断定年代的方法。

radiocarbon dating showed that the head「s age matched the king」s date of death.

放射性碳显示这个头颅的年龄符合国王的死期。
