The essential part of the apparatus is a sample tube surrounded by a helical xenon flash lamp stored in a cylindrical mirror, with an optical filter system, if necessary. A high-voltage capacitor bank charges the flash lamp, which is discharged in turn at triggering by high-frequency current. Polymer sample films were degraded by a number of flash irradiations repeated in sequence, in vacuum or in an inert gas. Degradation products were analyzed by a highly sensitive gas chromatograph with a hydrogen flame ionization director. Typical results on flash degradation of polymethyl methacrylate in vacuum and in nitrogen are shown.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA2400949000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学宇宙航空研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Aeronautical Science,University of Tokyo"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0372-1418","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":"AA00675986","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"KAMBE, Hirotaro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"WATANABE, Hiroaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAGATOMO, Shigeru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ITOH, Yutaka","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":"SA2400949.pdf","filesize":[{"value":"606.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA2400949.pdf","url":"https://jaxa.repo.nii.ac.jp/record/34484/files/SA2400949.pdf"},"version_id":"bfa02f21-d147-4425-9cf1-9f970a75f3f5"}]},"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":"An Apparatus for Measurement of the Flash Degradation of Polymers","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"An Apparatus for Measurement of the Flash Degradation of Polymers","subitem_title_language":"en"}]},"item_type_id":"9","owner":"1","path":["1890","1992"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"34484","relation_version_is_last":true,"title":["An Apparatus for Measurement of the Flash Degradation of Polymers"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:41:08.827501+00:00"}
