In order to investigate plasma-quenching ability of various gases, Four kinds of environmentally-benign gases such as N_2, H_2, Q_2 and CO_2 was injected into Ar PMITP. The results indicates that inclusion of CO_2 decays drastically the stable operation region of PMITP. This means that CO_2 has a higher plasma-quenching ability compared with the other gases treated in the experiment.\n2) Effect of gas inclusion on transient behavior of pulse-modulated induction thermal plasma\nGas inclusion affect transient behavior of PMITP, which is also markedly related with plasma-quenching ability of gases. We measured time evolution of radiation intensity of Ar line emitted from PMITP with added gases. As a result, CO_2 inclusion made transient behavior of PMITP delayed. This also indicates that CO_2 has high plasma-quenching ability.\n3) Effect of gas inclusion on time variation in Ar excitation temperature\nThe time-resolved radiation intensity measurement permitted us to estimate Ar excitation temperature of PMITP. Two-line method of Ar spectral line was used for this temperature estimation. The results revealed that CO_2 inclusions decayed Ar excitation temperature markedly compared with the other gases.\n4) Temperature measurement of laser-induced plasma\nIn order to study the dielectric strength of high-temperature gas, laser-induced plasma technique was adopted. Temperature was evaluated from Boltzmann plot method on the assumption of local thermal equilibrium. From the result, laser-induced plasma temperature can be estimated.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:13450111, 研究期間(年度):2001–2002","subitem_description_type":"Other"},{"subitem_description":"出典：「パルス変調誘導熱プラズマを用いたSF_6代替環境調和形消弧媒体の開発」研究成果報告書　課題番号13450111\n  (KAKEN：科学研究費助成事業データベース（国立情報学研究所）)\n　　　本文データは著者版報告書より作成\n","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00034793","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=90303263&st=21","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-13450111/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-13450111/134501112002kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-05"}],"displaytype":"detail","filename":"TE-PR-TANAKA-Y-kaken 2003-93p.pdf","filesize":[{"value":"5.3 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"TE-PR-TANAKA-Y-kaken 2003-93p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/34806/files/TE-PR-TANAKA-Y-kaken 2003-93p.pdf"},"version_id":"7f6dc1de-5601-4b5b-92ac-763ac923941d"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"パルス変調誘導熱プラズマを用いたSF_6代替環境調和形消弧媒体の開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"パルス変調誘導熱プラズマを用いたSF_6代替環境調和形消弧媒体の開発"},{"subitem_title":"Development of environmental-friendly arc quenching medium alternative to SF_6 using pulse modulated induction plasma","subitem_title_language":"en"}]},"item_type_id":"9","owner":"3","path":["2831"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-05"},"publish_date":"2017-10-05","publish_status":"0","recid":"34806","relation_version_is_last":true,"title":["パルス変調誘導熱プラズマを用いたSF_6代替環境調和形消弧媒体の開発"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T14:41:33.611574+00:00"}
