In the calculation of radiation, molecular bands, atomic lines and continuum processes are included. These results are applied to a simple shock layer model to assess the effectiveness of the ablation layers for a blockage of high-temperature radiation from a stagnation shock layer composed of hydrogen and helium. The results show that the photoionization process of a Si atom is mainly responsible for blocking the radiation, and that the Si_3N_4 ablation layer is very effective in reducing the radiative heating due to high-energy photons.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0033587000","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":"0288-433X","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":"AA10455137","subitem_source_identifier_type":"NCID"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Faculty of Engineering, Gunma University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"SHIRAI, Hiroyuki","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":"2020-01-23"}],"displaytype":"detail","filename":"SA0033587.pdf","filesize":[{"value":"496.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0033587.pdf","url":"https://jaxa.repo.nii.ac.jp/record/31318/files/SA0033587.pdf"},"version_id":"438c8175-a74e-43a2-8e54-929af7423900"}]},"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":"Absorption Characteristics of Si_3N_4 Ablation Layer Plasma","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Absorption Characteristics of Si_3N_4 Ablation Layer Plasma","subitem_title_language":"en"}]},"item_type_id":"9","owner":"1","path":["1890","1991"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"31318","relation_version_is_last":true,"title":["Absorption Characteristics of Si_3N_4 Ablation Layer Plasma"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T01:03:40.280587+00:00"}
