项目摘要

Age of carbon in an iron product is regarded to originate on age of the charcoal which was used at the time of iron manufacture. A way ^<14>C age measurements of an iron product is utilized using this precondition. But, it is actual for the verification the precondition is right that it is not performed.In order to verify this precondition, they went along iron-manufacturing experiment first of all. Carbon was recovered by amount purity from the iron lump and so on which was got by this iron-manufacturing experiment efficiently and they went along ^<14>C age measurements by an accelerator mass spectrometer. The measuring result showed charcoal before use and roughly identical age, and a career of carbon verified to originate on the charcoal which was used at the time of iron manufacture.Secondly, they went along verification using the iron-manufacturing ruins excavation iron lumps whose to fix age of ruins from excavating Sue ware is possible. As a result, age of charcoal in an iron lump and the rust showed roughly identical age, and the prerequisite efficiency which becomes foundation of a way of ^<14>C age measurements could be recognized from ruins excavation data.From a thing of the above, it is thought that age of carbon in the iron lump which was done refinement originates in an annual ring formative time of the wood which was used at the time of iron manufacture. In other words, by clarifying rearing age of the trees which is raw material of the charcoal which was used by refinement process, it was possible to give refinement age of an iron product.

铁产品中碳的年龄被认为源于制造铁时使用的木炭的年龄。在此前提条件下，采用了一种铁产品< 14b> C年龄测量方法。但是，对于验证的实际前提是不执行。为了验证这一前提条件，他们首先进行了炼铁实验。从铁块中回收碳的数量纯度等，这是铁制造实验有效地得到的，他们沿着^<14>的碳年龄进行了加速器质谱仪测量。测量结果显示使用前的木炭和大致相同的年龄，并且碳的职业证实来自于制造铁时使用的木炭。其次，利用炼铁遗址出土的铁块进行了验证，证明了通过挖掘苏器确定遗址年代是可能的。结果表明，铁块中木炭的年龄与铁锈的年龄基本一致，这为从遗址挖掘资料中识别出^<14>C年龄测定方法奠定了基础。综上所述，可以认为炼铁过程中铁块中碳的年龄源于炼铁时所用木材的年轮形成时间。换句话说，通过澄清树木的饲养年龄这是精炼过程中使用的木炭的原料，有可能给出铁产品的精炼年龄。
