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

金属器物是一种特殊的生产系统所必需的材料供应和制作方式的遗物，由于特别是金、银等特殊材料和加工需要技术工艺，金铜器很难想象它是在个人和小殖民地制造的。从朝鲜半岛引进的技术到大约五世纪内总是发展得很高，基于以上情况，本研究从考古学和自然科学的角度对金铜器的材质、制作工艺等进行分析。青铜器和含铅铜中的铅的同位素比分析，除了以前专门进行的X射线荧光分析外，还进行了分析，用于帮助研究材料的循环。装饰性大剑和镀金马具的铅同位素比值分析取样困难。因此，我们通常从耳环中取样。耳环作为研究和分析的对象，在日本流行于六世纪，它是从各个地区的古墓群中提取的，然后应用X射线荧光分析和铅同位素比值分析。结果表明，经调查证实，该古墓（古墓群）中的铜耳环含铅砷，存在倾斜现象。古墓葬群之间的相关性得到证实。它既注重法的量和今后要做精度更高的调查，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.
