Elastic waves passing through an aperture of a screen are diffracted in complex manners. 2. When the barriers are free from stress and the primary waves, propagated perpendicularly to the barriers, are purely dilatational, the diffracted waves are of two kinds, that is, dilatational and distortional types, energy of each kind of waves being of comparable magnitude. 3. When the barriers are very rigid and the primary waves are of the same nature as the above case, the principal diffracted waves are of the dilatational kind, resembling to the diffraction phenomena of sound waves.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"135139","nameIdentifierScheme":"WEKO"}],"names":[{"name":"妹澤, 克惟"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000035039","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京帝国大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00029699","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408972","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute, Tokyo Imperial University"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"地震研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sezawa, Katsutada"}],"nameIdentifiers":[{"nameIdentifier":"135138","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":"2017-06-27"}],"displaytype":"detail","filename":"ji0050005.pdf","filesize":[{"value":"444.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0050005.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/35039/files/ji0050005.pdf"},"version_id":"bfa84969-56fb-4303-b75c-873115abbe42"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"On the Diffraction of Elastic Waves","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"On the Diffraction of Elastic Waves","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["5277","5278"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-06-06"},"publish_date":"2008-06-06","publish_status":"0","recid":"35039","relation_version_is_last":true,"title":["On the Diffraction of Elastic Waves"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:51.919548+00:00"}
