The repaired pipeline system cannot be evaluated to water-leak phenomena under refillingprocess. Non-destructive evaluation of water-tightness in pipeline system is currently in urgent demand. In this study,acoustic emission (AE) method is applied to the evaluation of water-tightness in service and model pipeline systems. Theresults show that water-tightness in the pipeline system could be quantitatively evaluated by using AE parameters, such asAE generation behavior, AE energy and RMS voltage. Thus, it becomes clear that when a pipeline is being filled with waterafter the repair, the situation of water-tightness in the pipeline can be clearly identified through AE monitoring.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "162921", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Suzuki, Tetsuya"}]}, {"nameIdentifiers": [{"nameIdentifier": "162922", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Naka, Tatsuo"}]}, {"nameIdentifiers": [{"nameIdentifier": "162923", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Taruya, Hiroyuki"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟大学農学部"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00183393", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03858634", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "鈴木, 哲也"}], "nameIdentifiers": [{"nameIdentifier": "162918", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "中, 達雄"}], "nameIdentifiers": [{"nameIdentifier": "162919", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "樽屋, 啓之"}], "nameIdentifiers": [{"nameIdentifier": "162920", "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": "2019-08-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "64(1)_49-54.pdf", "filesize": [{"value": "1.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1200000.0, "url": {"label": "64(1)_49-54.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/28341/files/64(1)_49-54.pdf"}, "version_id": "c329ec91-b02a-46c5-a539-23da45a7b0c3"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "AE", "subitem_subject_scheme": "Other"}, {"subitem_subject": "非破壊検査", "subitem_subject_scheme": "Other"}, {"subitem_subject": "パイプライン", "subitem_subject_scheme": "Other"}, {"subitem_subject": "水密性能", "subitem_subject_scheme": "Other"}, {"subitem_subject": "acoustic emission", "subitem_subject_scheme": "Other"}, {"subitem_subject": "non-destructive inspection", "subitem_subject_scheme": "Other"}, {"subitem_subject": "pipeline", "subitem_subject_scheme": "Other"}, {"subitem_subject": "water-tighness", "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": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "非破壊弾性波モニタリングによる農業用パイプラインの水密性評価に関する実証的研究", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "非破壊弾性波モニタリングによる農業用パイプラインの水密性評価に関する実証的研究"}, {"subitem_title": "非破壊弾性波モニタリングによる農業用パイプラインの水密性評価に関する実証的研究", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1594"], "permalink_uri": "http://hdl.handle.net/10191/18625", "pubdate": {"attribute_name": "公開日", "attribute_value": "2012-07-02"}, "publish_date": "2012-07-02", "publish_status": "0", "recid": "28341", "relation": {}, "relation_version_is_last": true, "title": ["非破壊弾性波モニタリングによる農業用パイプラインの水密性評価に関する実証的研究"], "weko_shared_id": null}
