W₁ = W₃ρ₁(1-p) / ρ₁-p(ρ₁-ρ₂) W₁ : weight of pottery except for a filling material W₂ : weight of a filling material W₃ : weight of pottery and a filling material p : proportion of a filling material (0<p<1) ρ₁ : density of pottery ρ₂ : density of a filling material (plaster) In addition, density of potteries( ρ₁) and a filling material( ρ₂) was calculated. The result was as follows. ρ₁=1.85 1.00 < ρ₂<1.80 And these numerical values were substituted ρ₁(1.85) and ρ₂(1.10, 1.30, 1.50 and 1.70) for a above formula. For reference, a number of plant seeds impressions per 10kg of potteries from one site were calculated to compare with another site by using this formula. As a result, the difference between the numerical values of filling materials(1.00 < ρ₂<1.80) had little influence on comparison between them.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"60576","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MORIYA, Ryo"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00027584","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院人文社会系研究科・文学部考古学研究室"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11190220","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18803784","subitem_source_identifier_type":"ISSN"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Department of Archaeology Faculty of Letters, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"守屋, 亮"}],"nameIdentifiers":[{"nameIdentifier":"60575","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-12"}],"displaytype":"detail","filename":"kouko3004.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kouko3004.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/27593/files/kouko3004.pdf"},"version_id":"b9dfe9ec-e0cc-421f-8adf-7d114298f305"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"種実圧痕の定量分析に関する予察 : 補填材重量の検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"種実圧痕の定量分析に関する予察 : 補填材重量の検討"}]},"item_type_id":"4","owner":"1","path":["3298","3296"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-04-21"},"publish_date":"2016-04-21","publish_status":"0","recid":"27593","relation_version_is_last":true,"title":["種実圧痕の定量分析に関する予察 : 補填材重量の検討"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:05:34.613431+00:00"}
