A set of simultaneous differential equations for the oscillation is obtained in a general form which contains harmonic constituents of successive degrees. Although the writer can not solve the equation rigorously, some features of the coupling are qualitatively examined. A simple normal mode of the free oscillation is also studied by taking into account only the S10 and S30 type magnetic fields.","subitem_description_type":"Abstract"},{"subitem_description":"前論文に於て地磁気永年変化に対応すると考えられる地球核内の電磁流体振動を論じる際に,ことなつたデグリーのポロイダルまたはトロイダル磁場間の相互の影響を無視した.この影響を見るために,もつとも簡単な場合として外部から一様な磁場を与えた時の導電流体球の電磁流体振動を論じた.その結果一般的方程式を求め得たが,各デグリーの成分が互に関係しあう連成振動となり,その固有値を求めることは容易でないことがわかつた.そこで比較的簡単な帯状振動について特に考察したところ,定性的には有意義な結果を得た.また第5次以上の振動を省略した場合について,近似的に基準振動を求めた.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"132661","nameIdentifierScheme":"WEKO"}],"names":[{"name":"力武, 常次"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000034028","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162258","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, University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"RIKITAKE, Tsuneji"}],"nameIdentifiers":[{"nameIdentifier":"132660","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":"ji0332001.pdf","filesize":[{"value":"900.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0332001.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/34028/files/ji0332001.pdf"},"version_id":"4109fdc3-41d6-4341-b69e-9db34ab0b2ef"}]},"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":"Magneto-hydrodynamic Oscillations of a Conducting Fluid Sphere in a Uniform Magnetic Field","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Magneto-hydrodynamic Oscillations of a Conducting Fluid Sphere in a Uniform Magnetic Field","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["5053","5054"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-05-30"},"publish_date":"2008-05-30","publish_status":"0","recid":"34028","relation_version_is_last":true,"title":["Magneto-hydrodynamic Oscillations of a Conducting Fluid Sphere in a Uniform Magnetic Field"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:09:14.424183+00:00"}
