This component is always accompanied by a sudden change in the solar wind parameters such as interplanetary shocks. The difference of bulk speed between the low energy component and normal one amounts to about 60-140km/s, and is strongly affected by the configuration of the interplanetary magnetic field. It is shown that this low energy component was produced by the gyromotion of protons, through an acceleration mechanism, e. g., Fermi process. Furthermore, it seems that there are two types of accelerative process, though these mechanisms are unknown.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166885000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9920","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354485","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"電気通信大学"},{"subitem_text_value":"京都大学理学部"},{"subitem_text_value":"電気通信大学"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"阿部, 琢美"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小山, 孝一郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"寺沢, 敏夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"奥沢, 隆志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ABE, Takumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OYAMA, KohIchiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TERASAWA, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OKUZAWA, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"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":"SA0166885.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0166885.pdf","url":"https://jaxa.repo.nii.ac.jp/record/33036/files/SA0166885.pdf"},"version_id":"c80884cb-ec0c-4cb7-8c81-19d61015b28b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"非熱的粒子","subitem_subject_scheme":"Other"},{"subitem_subject":"衝撃波","subitem_subject_scheme":"Other"},{"subitem_subject":"不連続面","subitem_subject_scheme":"Other"},{"subitem_subject":"速度分布空間","subitem_subject_scheme":"Other"},{"subitem_subject":"旋回運動","subitem_subject_scheme":"Other"}]},"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":"「さきがけ」による太陽風中の非熱的粒子の観測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"「さきがけ」による太陽風中の非熱的粒子の観測"}]},"item_type_id":"9","owner":"1","path":["1890","1912"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"33036","relation_version_is_last":true,"title":["「さきがけ」による太陽風中の非熱的粒子の観測"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:17:28.470207+00:00"}
