Study on the production age and distribution of Ezo Nishiki

绫藏锦（日语：绫锦）是中国制造的丝织品。在前现代时期，它们通过库页岛和阿穆尔河下游地区输入到北海道县。在北海道和青森县发现了大约50件锦缎。研究表明，这些织锦多为清代（世纪）以后的推测。然而，文献研究表明，中国制造的丝织品在元代（世纪）和明代（世纪）也有进口。本文的研究目的是明代叶佐织锦的发现，叶佐织锦是北方贸易的证据，因此引起人们的注意和研究。以往的研究所依据的是，设计格式与文章的相对年龄相比较。本研究的目的是通过放射性碳测年法来确定其绝对年龄。在研究计划中，我们对萨哈林、北海道、青森和秋田县的叶佐织锦进行了研究。我们提取了分析材料的可能性。对14件锦制品的绝对年代进行了鉴定。所有的织锦都是清代的资料。总之，明代的资料没有被发现。

Brocade of Yezo (in Japanese Ezo Nishiki) is Chinese-made silk fabrics. These were imported to the Hokkaido Prefecture via the Sakhalin and the lower Amur region in the pre-modern time. About 50 brocades were found in the Hokkaido and the Aomori Prefecture. The design studies showed that most of these brocades were surmised since Qing era (the 17th century). However the literature studies showed that Chinese-made silk fabrics were imported also in Yuan era (the 13th century) and Ming era (the 15th century). The intention of this study is the discovery of Brocade of Yezo in Ming era.The Brocade of Yezo is the evidence of the northern trade, so they were noticed and studied. Previous studies relied on, the design format and the relative age based on article compares. The intention of this study is elucidation of the absolute age based on radiocarbon dating.During the research plan, we researched the Brocade of Yezo in the Sakhalin, the Hokkaido, the Aomori and the Akita Prefecture. We extracted analysis material possibility. The absolute age of 14 brocades were elucidated. All brocades were data in Qing era. In short, data on Ming era were not discovered.
