The rate of permeation of tritium is determined by fugacity of tritium dissolution and diffusivity of hydrogen in metals. Atomic tritium permeated through the metals is released into water by oxidation of atomic tritium to water form. The effects of stress or strain on tritium permeation is very small.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究（Ｂ）;  研究期間：2014～2017;   課題番号：26289364;   研究分野：材料科学、トリチウム理工学、材料-水素相互作用;   科研費の分科・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-26289364/"}]}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"OTSUKA,Teppei"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 准教授"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大塚, 哲平"},{"creatorName":"オオツカ, テッペイ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-11-20"}],"displaytype":"detail","filename":"26289364seika.pdf","filesize":[{"value":"2.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"26289364seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/19705/files/26289364seika.pdf"},"version_id":"e1d5c09e-ba11-4b10-9e87-dc76f0780824"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"トリチウム","subitem_subject_scheme":"Other"},{"subitem_subject":"透過","subitem_subject_scheme":"Other"},{"subitem_subject":"腐食","subitem_subject_scheme":"Other"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"金属の水腐食によるトリチウムの取り込み・透過機構の解明","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"金属の水腐食によるトリチウムの取り込み・透過機構の解明"},{"subitem_title":"Tritium permeation induced by water corrosion of metals","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4459"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-11-20"},"publish_date":"2018-11-20","publish_status":"0","recid":"19705","relation_version_is_last":true,"title":["金属の水腐食によるトリチウムの取り込み・透過機構の解明"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T21:35:49.677524+00:00"}
