The correlation with the production technique of the gold copper ware and the quality of the material from the ancient tomb (KOFUN)

金属制品是材料的供应和制造方式所必需的特殊生产系统的遗物。因为特别特殊的材料，如金银和加工采取技术技术，金铜器很难认为它是在个人和小群体中制造的。公元5世纪左右从朝鲜半岛引进的技术，在古坟时代更是发展成为高新技术。在此基础上，本研究从考古学和自然科学的角度对金铜器的材料质量、制作工艺等进行了分析。在以往专门进行的x射线荧光分析的基础上，对青铜中铅和含铅铜进行了同位素比分析，以帮助研究材料的循环。对装饰用的大剑和镀金马具进行铅同位素比分析是比较困难的。所以，我们通常从耳环上取样。作为研究对象和分析对象的耳环在日本流行于6世纪，它是从各个地区古墓群的组成物中提取出来的，然后应用x射线荧光分析和铅同位素比分析。结果证明，铜制耳环的古墓（古墓群）有倾斜，其中含有铅和砷。证实了古墓群之间的相关性。在关注缺陷数量的同时，今后将对其进行精度较高的调查，同时也要对标准的存在进行调查。

Metal objects are the relics that a special production system is necessary for the supply of the material and the way of making it. Because especially special material such as gold and silver and processing take technical technology, gold copper ware is hard to think that it was being made in the individual and the small colony.The technology imported from the Korean Peninsula into about the fifth century inside always develops as a high technology through the Kofun Period more.Based on the above conditions, this study is analyzing the quality of the material, the production technique, and so on with the gold copper ware from the viewpoint like archeology and natural science. The isotope ratio analysis of lead contained in bronze and copper including lead was enforced in addition to the X-rays fluorescence analysis which had specially been this time since before, and used for a help to research the circulation of the material. It was difficult for sampling from decorative big swords and harnesses with gilding for the lead isotope ratio analysis were. So, we usually picked sample from earrings.Earrings made the target of the research and the analysis are popular in sixth century in Japan, it is extracted from the thing which composes the group of ancient tombs in each area, then applied the X-rays fluorescence analysis and lead isotope ratio analysis.As the result, it was proved that there was inclination in the ancient tomb (the group of ancient tombs) which had the earrings made of copper contained lead and arsenic. Correlation confirmed between groups of ancient tombs. It pays attention to the amount oflaw as well with will do the investigation whose precision is higher from now on, and wants to proceed with the investigation as for the existence of the standard as well.
