In the drag net, the length was 6.1 m; the ratio between the diameter of a twine (d mm) and the mesh size (l mm), namely d/l=0.021. The results obtained areas follow: a) The current velocity inside the net body (v m/sec) was ascertained to be almost invariably higher than that at the net mouth (v_0 m/sec); this tendency was noted to be especially remarkable when the cod end was kept opened. The value of v/v_0 obtained from the theoritical formula on the velocity ratio inside and outside the net, namely [the formula is omitted] was ascertained to be 1.21, in case of the theoritical value, and 1.11 in case of the experimental value: here the difference was noted to be almost zero, considering the possible errors in measurement. b) The relationship between the net resistance (R kg) and the towing speed (V m/sec) was ascertained to be: In case of the closed cod end: R=213V^{1.48}. In case of the opened cod end: R= 184V^{1.37}. By this was shown the fact that the variation of the net shape in the net shape in the former net was less than that in the latter one.","subitem_description_type":"Other"}]},"item_7_full_name_3":{"attribute_name":"別言語の著者","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"肥後, 伸夫"}]},{"nameIdentifiers":[{}],"names":[{"name":"毛利, 公朗"}]}]},"item_7_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学"}]},"item_7_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0453087X","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_9":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00040498","subitem_source_identifier_type":"NCID"}]},"item_7_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"665","subitem_subject_scheme":"NDC"}]},"item_7_text_24":{"attribute_name":"公開者よみ","attribute_value_mlt":[{"subitem_text_value":"カゴシマ ダイガク"}]},"item_7_text_25":{"attribute_name":"公開者別名","attribute_value_mlt":[{"subitem_text_value":"Kagoshima University"}]},"item_7_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"HIGO, Nobio"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MOURI, Kourou"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-28"}],"displaytype":"detail","filename":"AN00040498_v24_p57-63.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN00040498_v24_p57-63.pdf","url":"https://ir.kagoshima-u.ac.jp/record/4662/files/AN00040498_v24_p57-63.pdf"},"version_id":"11af76f3-a932-4dbf-be6d-66b5bdd1d9f4"}]},"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":"Studies on the Drag Net IV : On the Towing Experiments of the Big sized Drag Net","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Studies on the Drag Net IV : On the Towing Experiments of the Big sized Drag Net"}]},"item_type_id":"7","owner":"3","path":["40","4833"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-05-09"},"publish_date":"2012-05-09","publish_status":"0","recid":"4662","relation_version_is_last":true,"title":["Studies on the Drag Net IV : On the Towing Experiments of the Big sized Drag Net"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2024-01-30T05:47:07.289049+00:00"}
