When the conditions 𝛾2=∑_e,i ms v^2 s0/∑_e,i kTs=1 and E0=0, (where the subscript s stands for e (electron) and i (ion), ms is the mass of a particle, vs0 the velocity at the plasma-sheath boundary, Ts the temperature and E0 the electric field at the boundary, (i) for miv^2 i0/kTi\u003e1 (or mev^2 s0/kTe\u003c1) the pure ion sheath is formed without any local excess of electron space charge, (ii) for miv^2 i0/kTi=1 (or mev2 s0/kTe=1) any sheath is not established and (iii) for miv^2 i0/kTi\u003c1 (or mev^2 s0/kTe\u003e1 ) the pure electron sheath is developed. When 𝛾2≠1 and E0=0 or ≠0 , then the formation of sheath is much complicated. Thus the conditions 𝛾=1 and E0=0 lead to the establishment of much simple sheathes among the various sheathes and are including the familiar Bohm criterion when ve0→0.   Furthermore, one may find that the ideal Langmuir probe curve, in which the conditions 𝛾2=1 and E0=0 are imposed, deviates from the classical probe theory.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/memfenu.16.55", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Faculty of Engineering, Nagoya University", "subitem_publisher_language": "en"}]}, "item_9_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_source_id_7": {"attribute_name": "ISSN（print）", "attribute_value_mlt": [{"subitem_source_identifier": "0027-7657", "subitem_source_identifier_type": "PISSN"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Miyajima, Shigeki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "103250", "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": "2021-02-04"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "16-04.pdf", "filesize": [{"value": "1.2 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 1200000.0, "url": {"label": "16-04.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/31296/files/16-04.pdf"}, "version_id": "6bda2ee0-9c7f-4255-a218-eb0ea0b31c8d"}]}, "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": "Note on sheath formation", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Note on sheath formation", "subitem_title_language": "en"}]}, "item_type_id": "9", "owner": "1", "path": ["2627"], "permalink_uri": "https://doi.org/10.18999/memfenu.16.55", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2021-02-04"}, "publish_date": "2021-02-04", "publish_status": "0", "recid": "31296", "relation": {}, "relation_version_is_last": true, "title": ["Note on sheath formation"], "weko_shared_id": -1}
