A paradox that an anomalous 'resistivity' contributes to acceleration of electrons is resolved by taking into account its different effects on electrons in different parts of the distribution function (PAPADOPOULOS : Rev. Geophys. Space Phys, 15, 113, 1977) ; bulk electrons carrying a field-aligned current are anomalously scattered and decelerated by collisions with turbulent electrostatic waves and contribute to maintain parallel electric field, which in turn accelerates electrons in the tail of the distribution. Among the possible instabilities the electrostatic ion cyclotron instability has the lowest threshold velocity for the wide range of T_e/T_i including T_e/T_i～1, which is valid in the upper ionosphere. The electrostatic ion cyclotron wave is destabilized by a relatively small field-aligned current in the upper ionosphere (KlNDEL and KENNEL : J. Geophys Res., 76, 3055, 1971). A numerical model of the field-aligned acceleration by SATO (Symposium on Plasma Waves in the Magnetosphere, 66,1978) is reviewed in order to emphasize an important role of the ionosphere ; the existence of a resistive external circuit (ionosphere) is necessary for resolving the 'chickenegg' cause and effect relationship among parallel electric field, anomalous resistivity and formation of runaway (accelerated) electrons precipitating downward into the ionosphere.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00008112","subitem_identifier_reg_type":"JaLC"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00181831","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00857289","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_21":{"attribute_name":"国際十進分類法","attribute_value_mlt":[{"subitem_subject":"551.510.535/.537","subitem_subject_scheme":"UDC"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Geophysics Research Laboratory, University of Tokyo"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"東京大学理学部地球物理研究施設"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1980-02-01"}],"displaytype":"detail","filename":"KJ00002477172.pdf","filesize":[{"value":"16.1 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00002477172","url":"https://nipr.repo.nii.ac.jp/record/8112/files/KJ00002477172.pdf"},"version_id":"cd4d5622-ca3f-4d8f-a19b-2675ea2dd8e1"}]},"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":"異常抵抗による沿磁力線加速(Review)(a.入射粒子とオーロラ)(第2回極域における電離圏磁気圏総合観測シンポジウム : Part I)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"異常抵抗による沿磁力線加速(Review)(a.入射粒子とオーロラ)(第2回極域における電離圏磁気圏総合観測シンポジウム : Part I)"},{"subitem_title":"A Review of Field-Aligned Acceleration by Anomalous Resistivity (a.
