The time variation of the form of the surface was followed kinematographically, especially for the cases when the amplitudes of oscillation are not small compared with the length and depth of the tank. In the case when the two liquids are of the equal depth the wave form may be reproduced approximately by the superposition of the second harmonics only, of which the amplitude bears a definite ratio to that of fundamental wave. When the depths of the two liquids are unequal, the third and fourth harmonics appear with sensible amplitudes. The ratio ai/a1 of the amplitude of the i-th. harmonics, ai, to that of the fundamental mode, a^1, may be represented as an algebraic function of (i-1)-th. order with respect to the distance of the equilibrium boundary surface from the middle height of the tank. When the amplitude of oscillation exceeds a critical value a train of short waves appear on the boundary surface, which is especially conspicuous near the node of the vertical motion where the relative horizontal velocity between the two liquids is greatest. This may be explained as the Helm holtz waves on the surface of discontinuity.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA4415983000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京帝國大學航空研究所"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162779","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"梅津, 藤市郎"}],"nameIdentifiers":[{"nameIdentifier":"422782","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":"2020-01-24"}],"displaytype":"detail","filename":"SA4415983.pdf","filesize":[{"value":"534.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA4415983.pdf","url":"https://jaxa.repo.nii.ac.jp/record/35790/files/SA4415983.pdf"},"version_id":"ccfecbd0-6da3-4de6-8303-d2ac2c6733e7"}]},"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":"二液の境界面に起る定常波動に就て","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"二液の境界面に起る定常波動に就て"}]},"item_type_id":"9","owner":"1","path":["1890","1906"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"35790","relation_version_is_last":true,"title":["二液の境界面に起る定常波動に就て"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:12:04.278948+00:00"}
