In case of the dyes, Uranine is very cheap for dyes, clear green color, and keeps clear clouds for about two hours in a sea. Accordingly we can trace easily edges of the clouds by boats. When we calculated the increment ratio of the cloud area, we used two different ways. They are instant gradiant (⊿A/⊿T) and mean gradiant (A/T). In mean gradiant way, the gradiant of diffusion coefficient was smaller than that of the rule of 4/3 (by Richardson), and the diffusion coefficients were 1.4×105 cm2/sec in Omura Bay and 1.6×105cm2/sec in Sasebo Bay at 900m-scale. When we apply the instant gradiant way, we must be carefull to measure the area of the dyes clouds. The gradiant of the diffusion coefficient by the velocity correlation method was smallest among the those we applied, but the value was greater than the other during about 2-3 hours. The diffusion coefficients of the correlation and the dyes methods were same 2.4×104cm2/sec at near 1 hour time-scale.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学工学部研究報告, (13), pp.13-22; 1979","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"59876","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Uto, Kouicoi"}]},{"nameIdentifiers":[{"nameIdentifier":"59877","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kurisu, Masato"}]},{"nameIdentifiers":[{"nameIdentifier":"59878","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nakane, Shigekatu"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学工学部"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00178418","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02860902","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"18805574","subitem_source_identifier_type":"ISSN"}]},"item_3_text_63":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"Faculty of Engineering, Nagasaki University"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"宇都, 幸一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"栗須, 正登"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中根, 重勝"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"kogaku00_13_03.pdf","filesize":[{"value":"585.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kogaku00_13_03.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/15987/files/kogaku00_13_03.pdf"},"version_id":"8b6f42da-fc48-40ef-8fb2-704592525454"}]},"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":"大村湾および佐世保湾における拡散係数","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"大村湾および佐世保湾における拡散係数"}]},"item_type_id":"3","owner":"2","path":["1270"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-09-16"},"publish_date":"2010-09-16","publish_status":"0","recid":"15987","relation_version_is_last":true,"title":["大村湾および佐世保湾における拡散係数"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-17T21:03:08.703219+00:00"}
