查询词典 radiocarbon

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。

Then, taking into consideration that radiocarbon inconsistencies have shown up in such a relatively short period of time, who's to say that the rate of today's radioactive bombardment is not totally out of whack with what it was billions, millions, or even thousands of years ago.

然后，考虑到放射性矛盾已经显露出来，在这样一个相对较短的时间里世卫组织说，利率今天的轰击放射性并非完全出于与失衡，这是作什么几十亿，几百万，甚至几千年前。

Using radiocarbon dating techniques, simulations and computer models, the researchers recreated the ancient disaster in order to identify the responsible fault.

应用放射性碳测定年代技术、仿真技术和计算机模型，研究人员再现了那次古代的灾难以确定可能引发灾难的断裂带。

Ross-Ibarra defends his estimate by explaining that his team couldn't age the bushes using radiocarbon dating, because they couldn't find any old pieces of wood.

Ross-Ibarra为他的估计做出的辩护是他的团队不能使用放射性碳测试年龄的方法来确定这些灌木的年代，因为他们无法找到旧的木头片。

Accelerators are also used for radioisotope production, cancer therapy, Biological sterilization, and one form of radiocarbon dating.

加速器也用于制造放射性同位素、治疗癌症、生物消毒及放射性碳定年。

Organic matter less than 7000 years old can be dated using radiocarbon dating, This uses the fact that the isotope carbon-14 is found in the atmosphere and taken in by plants when they photosynthesize, and subsequently assimilated by the animals that feed on them.

在7000年以内的有机体可以用放射性碳来推测它的年代。

Between 2,500 yr BP and 1,800 yr BP. This was a neo-glacial age with a cold snap. The ice-cap on the King George Island and Ardley Island advanced. Iso -static adjustment lowered the palaeo -first terrace at the edge of Ardley Island under the high tide sea level. This made the rookeries around Y2 lake disappear and Y2 lake changed into a lagoon. The fact of Y2 lake under the sea level was coincident with the radiocarbon age (2180±95 yr BP) of the modern third raised beach terrace with 14m-height above the sea level near Yin ' Ou lake in the Fildes Peninsula.

第二阶段，距今1，800至2，500年，该时期气候骤冷，温度急降，该时期乔治王岛的冰帽有所扩张，同时在阿德雷岛上也出现小规模冰进，由于&地壳均衡&补偿使得该岛边缘古一级阶地处于高潮海平面之下，Y2湖周围的企鹅聚居地消失，该时期 Y2湖沉积表现为泻湖相沉积，与 Y2湖相邻的 Fildes 半岛燕鸥湖边海拔14米的上升海滩的三级阶地14 C 年龄为2180±95yr。

A strange manuscript found inside and the unusually age-worn chest coupled with its noticeably unique design prompted them to conduct a radiocarbon test of the timber with which the chest was made.

结果发现里面有一份手稿，而箱子实在很古老，用来制作箱子的木材也十分奇特，于是决定用放射性碳来测算它的年代。

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.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
