项目摘要

The purposes stated in the application are, first to systematically mark with new radiocarbon dates and archaeological chronology in the Kinki District where ancient cultural and political centers were located, to reshuffle the relics and ruins here using the newly made scale, and second to make and release to the public their spatial and time-series database.The results already or nearly obtained are : a new Li2C2 method was developed to produce a response of melting Li and carbonized samples and consequently synthesize benzene, 2. a series of wood samples coexisting with chronologically used sherds of the Yayoi period have been dated in the Kawachi Plain of Osaka where an inland sea or marshy area had been extending and its resultant peaty deposits have kept relics and ruins well, and a radiocarbon scale of the Yayoi period has been made for the first time, 3. practical effects of the volumetric or weight ratio of scintillator solution to sample benzene in liquid scintillation spectrometry were examined for radiocarbon dating. It is concluded that solutions, containing the same concentrations, of the same ratio, 1.3 or more of scintillator solution to sample benzene show the same cpm/g and the same channel value of external standard spectrum, irrespective of different gross volumes of solutions. The addition of scintillator solution reduces background in 0.5 mL or so of benzene, and results in appreciably enlarged figure of merit, 4. an abecedarium for archaeological users of radiocarbon dating is published to advance in cooperation with chronological sciences, 5. the other studies are under way. Radiocarbon dating has been applied to restore the past sedimental environment. The framework for an archaeological and geographical databases of the Kinki District has been investigated multilaterally. Our homepage including the database will be opened to the public.

申请书中所述的目的是，首先在古代文化和政治中心所在的近畿地区系统地标记新的放射性碳年代和考古年代，并使用新制作的比例尺重新整理这里的遗迹和遗址，其次制作并向公众发布其空间和时间序列数据库。已经或即将获得的结果是：发展了一种新的Li_2C_2法，使Li和Li_2C_2样品产生熔融响应，从而合成苯。摘要在大坂河池平原发现了一系列与弥生时代的年代学碎片共存的木材样品，测定了其年代，并首次测定了弥生时代的放射性碳标度。考察了液体闪烁光谱法中闪烁液与样品苯的体积比或重量比对放射性碳测年的实际影响。可以得出结论，无论溶液的总体积如何，含有相同浓度、相同比例（闪烁剂溶液与样品苯的比例为1.3或更高）的溶液均显示出相同的cpm/g和相同的外标光谱通道值。闪烁体溶液的添加降低了0.5 mL左右苯中的背景，并导致品质因数明显增大，4。为放射性碳测年的考古用户出版了一本入门书，以与年代学合作推进，5。其他研究正在进行中。放射性碳测年法已被应用于恢复过去的沉积环境。对近畿地区考古和地理数据库框架进行了多边调查。我们的网页，包括数据库，将向公众开放。
