For detecting electric and magnetic fields radiated from the granite, four sets of electric and magnetic sensors were installed along the axis of the granite pillar by keeping a space between sensors and the granite surface. When an impulsive stress impact was imposed to the top of the granite pillar, electric and magnetic pulses were detected at each sensor position. The rising time of waveforms of the detected fields was delayed at far positions from the stress impact point. From the time delays, the propagation velocity of the shock wave in the granite was calculated as a speed of the P-wave in the granite. The present experimental result has clearly shown that the granite can excite electromagnetic field by the stress impact.","subitem_description_type":"Other"}]},"item_2_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"1","subitem_description_type":"Other"}]},"item_2_description_16":{"attribute_name":"アクセション番号","attribute_value_mlt":[{"subitem_description":"KJ00008062719","subitem_description_type":"Other"}]},"item_2_description_2":{"attribute_name":"ページ属性","attribute_value_mlt":[{"subitem_description":"P","subitem_description_type":"Other"}]},"item_2_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"研究論文","subitem_description_type":"Other"}]},"item_2_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Paper","subitem_description_type":"Other"}]},"item_2_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA11815191","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-3980","subitem_source_identifier_type":"PISSN"}]},"item_2_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"京都産業大学コンピュータ理工学部"},{"subitem_text_value":"京都大学防災研究所地震予知研究センター"},{"subitem_text_value":"京都大学防災研究所地震予知研究センター"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"筒井, 稔","creatorNameLang":"ja"},{"creatorName":"ツツイ, ミノル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"18105","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"柳谷, 俊","creatorNameLang":"ja"},{"creatorName":"ヤナギダニ, タカシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"6816","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"加納, 靖之","creatorNameLang":"ja"},{"creatorName":"カノウ, ヤスユキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"6817","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":"2018-01-28"}],"displaytype":"detail","filename":"KJ00008062719.pdf","filesize":[{"value":"477.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00008062719.pdf","url":"https://ksu.repo.nii.ac.jp/record/2615/files/KJ00008062719.pdf"},"version_id":"9395acc0-ed39-44f7-ac2f-63a344acdba7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"地中電磁波パルス","subitem_subject_scheme":"Other"},{"subitem_subject":"室内実験","subitem_subject_scheme":"Other"},{"subitem_subject":"花崗岩への圧力衝撃印加実験","subitem_subject_scheme":"Other"},{"subitem_subject":"励起電磁界検出","subitem_subject_scheme":"Other"},{"subitem_subject":"地震波速度","subitem_subject_scheme":"Other"},{"subitem_subject":"Electro-magnetic (EM) pulses in the earth","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"laboratory experiment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"impulsive stress impact to granite, detection of EM fields","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"P-wave","subitem_subject_language":"en","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":"花崗岩に衝撃を加えた時の電磁界放射実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"花崗岩に衝撃を加えた時の電磁界放射実験","subitem_title_language":"ja"},{"subitem_title":"カコウガン ニ ショウゲキ オ クワエタ トキ ノ デンジカイ ホウシャ ジッケン","subitem_title_language":"ja-Kana"}]},"item_type_id":"2","owner":"3","path":["190"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2018-01-28"},"publish_date":"2018-01-28","publish_status":"0","recid":"2615","relation_version_is_last":true,"title":["花崗岩に衝撃を加えた時の電磁界放射実験"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-09-28T00:58:17.402396+00:00"}
