The radiocarbon dating of ancient iron articles by accelerator mass spectrometer method The development and application

我们用加速器质谱仪(AMS)建立了古代铁器的放射性碳测年方法，并有目的地给出了一件铁器的直接生成值。该方法提取效率高，不污染铁样中固有的碳，并考察了古铁器放射性碳测年的有效性。通过锻造铁器实验，对我们用于铁器实验的木炭和铁器提供的铁样进行了AMS测年。之后我们考察了一代人的价值。结果，铁中的碳史表明，在将其用于铁器制造实验之前，其生成几乎与木炭相同。因此，我明白了铁中的碳史是由铁匠中使用的木炭所改变的。古代铁器中的碳影响着我在每一个生产过程中使用的木炭的碳。而且我是直接的，能够给出一代铁器，这样一种铁器中的碳史就可以通过做14&gt；C年代测定来代替。此外，我还能够确定对铁器进行14C测年的有效性。然而，由于我这次测量的样品的14C测年的离散度超过了测量误差，碳同位素的离散性使一些样品产生了离散性，一些时间差能够在用于铁器和铁器的木炭的14C测年中得到考虑。因此，为了提高对14C测年的准确程度，对一些样品进行了14C测年。对古代铁器的年代测定，出于我对这些现象的澄清的需要，在未来产生了这些现象。

We established the radiocarbon dating of ancient iron articles by accelerator mass spectrometer (AMS) method, and did that I gave the direct generation value to an iron articles with a purpose. The efficiency was good and extracted it in high purity without letting you pollute the carbon which was inherent in an iron sample and inspected the effectiveness of the radiocarbon dating of ancient iron articles.Through a forge blacksmithing experiment, I did the ^<14>C dating by AMS of the charcoal which we used for blacksmithing experiment and the iron sample provided by the blacksmithing process. We examined a generation value afterwards. As a result, the carbon history in iron showed the generation almost same as charcoal before using it for a blacksmithing experiment. Therefore I understood that a carbon history in iron was moved by charcoal used in the case of blacksmithing.Carbon in the ancient iron artifacts takes influence to carbon of the charcoal which I used for every each production process. And I was direct and was able to give the generation to an iron articles so that a carbon history in an iron articles was substituted for by doing the ^<14>C dating. In addition, I was able to identify the effectiveness as legitimacy of doing the ^<14>C dating of the iron articles.However, the dispersion that exceeded a measurement error in the ^<14>C dating of the sample which I measured this time, Carbon isotope discretion produces it to some samples, some time differences were able to be considered in a ^<14>C dating of charcoal used for blacksmithing and made iron articles.Therefore in order to raise an exact degree of the ^<14>C dating of the iron articles of the ancient times, the need that I elucidated produced these phenomena in future.
