The method is based on expanding an exact frequency equation into its asymptotic form by the use of the asymptotic formulas for the spherical Bessel functions and spherical Neumann functions which appear in it. An Earth is assumed to consist of a uniform solid mantle and a uniform liquid core. The equations are expressed in different forms corresponding to the different ray geometries in the Earth and are denoted in terms of reflection and transmission coeffi- cients and intercept times of relevant P and 5 rays.","subitem_description_type":"Abstract"},{"subitem_description":"弾性球の伸び縮み振動の特性方程式は,高振動数,高位相速度の仮定のもとでは大変簡単になる。これは,波線理論的には球内のP波とS波が分離するからである。しかし位相速度を有限に保つ場合には,P波とS波がcouplingをしている状態にあるので,その漸近式(高振動数近似)も複雑になる。ここでは単純なモデル(均質な固体マントルと均質な流体核より成る)で満足することにして,後者の場合に対する式の導出を試みた。方法は,正規モード理論による特性方程式(球Bessel関数,球Neumann関数とそれらの一次微分関数で表現される)を,そこに現れる関数の漸近式を用いて展開するというものである。方程式は,最終的には,実体波の反射係数,透過係数,intercept timeというような波線理論的な量て表現されており,それは球内の異なった波線伝播様式に対してそれぞれ異なっている。","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"78356","nameIdentifierScheme":"WEKO"}],"names":[{"name":"小高, 俊一"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000033071","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":"地震研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Odaka, Toshikazu"}],"nameIdentifiers":[{"nameIdentifier":"78355","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":"2017-06-13"}],"displaytype":"detail","filename":"ji0552001.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0552001.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/33071/files/ji0552001.pdf"},"version_id":"9d01f971-683b-4abd-8061-9b10efc2deaa"}]},"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":"Asymptotic Frequency Equations for Spheroidal Oscillations of a Spherical Earth with a Uniform Mantle and Care : Modes of Finite Phase Velocity","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Asymptotic Frequency Equations for Spheroidal Oscillations of a Spherical Earth with a Uniform Mantle and Care : Modes of Finite Phase Velocity","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["4833","4834"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-10-04"},"publish_date":"2010-10-04","publish_status":"0","recid":"33071","relation_version_is_last":true,"title":["Asymptotic Frequency Equations for Spheroidal Oscillations of a Spherical Earth with a Uniform Mantle and Care : Modes of Finite Phase Velocity"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:54.960310+00:00"}
