In high pressure, the relation between the thermal conductivity k and air pressure p is \nk=A log p +B \nwhere A is a constant independent of a particle diameter, B is a constant depen­dent on a particle diameter. In the pressure range which is lower than 10-²mmHg, the thermal conductivity of the powder is almost independent of air pressure. \n(2) When the packing densities are same, the smaller a particle diameter is, the smaller the thermal conductivity is. If the particle diameters are extremely small, the values of the thermal conductivities become independent of the powder materials. \n(3) The smaller the porespaces in powders are, the larger the thermal insula­tion effect becomes. As the nature of powders for vacuum thermal insulation, it is necessary that particle diameters and porespaces are small.","subitem_description_type":"Abstract"}]},"item_7_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00011839","subitem_identifier_reg_type":"JaLC"}]},"item_7_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"金沢大学工学部 = Faculty of Technology Kanazawa University"}]},"item_7_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00044309","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0022-832X","subitem_source_identifier_type":"ISSN"}]},"item_7_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"若島, 久男"}],"nameIdentifiers":[{"nameIdentifier":"18436","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"桑名, 一利"}],"nameIdentifiers":[{"nameIdentifier":"18642","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":"2017-10-03"}],"displaytype":"detail","filename":"AN00044309-3-2-49.pdf","filesize":[{"value":"132.4 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"AN00044309-3-2-49.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/11852/files/AN00044309-3-2-49.pdf"},"version_id":"2f7d2573-9a05-4f53-be7a-8fb1c0c5991b"}]},"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":"多孔物質の特性とその応用に関する研究 III","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"多孔物質の特性とその応用に関する研究 III"},{"subitem_title":"On the physical properties of porous meterials and their applications Part III : Supplement of Part II","subitem_title_language":"en"}]},"item_type_id":"7","owner":"3","path":["1039"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"11852","relation_version_is_last":true,"title":["多孔物質の特性とその応用に関する研究 III"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2024-05-20T04:30:25.996332+00:00"}
