Yet such a problem has not been much studied for the reason that it involves mathematical difficulty and more probably has escaped the notice of investigators. So far as the author is aware, successful attempts hitherto made are for statical problems by Wangerin and a few others. Although the existing formulae in mathematics are not sufficient for solving the present subject, yet the author has succeeded to carry out a mathematical investigation more or less satisfactorily. The present investigation consists of three sections : the first is on two-dimensional propagation of waves from an elliptical origin, the second on the transmission of waves from an origin of prolate spheroid and the third on that from an origin of a oblate spheroid. In the following analysis, special attention should be given to the vibratory motion at the origin, wave fronts at infinity and the distribution of energy of waves in all directions.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"135245","nameIdentifierScheme":"WEKO"}],"names":[{"name":"妹澤, 克惟"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000035080","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":"Earthquake Research Institute"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sezawa, Katsutada"}],"nameIdentifiers":[{"nameIdentifier":"135244","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":"ji0020004.pdf","filesize":[{"value":"613.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0020004.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/35080/files/ji0020004.pdf"},"version_id":"91de6295-267f-4091-843f-4432e3b5aa60"}]},"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":"Propagation of Elastic Waves from an Elliptic or a Spheroidal Origin","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Propagation of Elastic Waves from an Elliptic or a Spheroidal Origin","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["5283","5284"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-10-13"},"publish_date":"2009-10-13","publish_status":"0","recid":"35080","relation_version_is_last":true,"title":["Propagation of Elastic Waves from an Elliptic or a Spheroidal Origin"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:09:50.409591+00:00"}
