The theoretical variance can be easily obtained when the number-proportion of particles to be mixed is previously given. However, the theoretical variance based on the particle mass-concentration in samples is difficult to obtain and it cannot be treated in the same manner as the number proportion, especially when the particles are composed with different size or weight each other. In this paper, the relations of the theoretical variances between number-proportion and mass-concentration are investigated in order to evaluate the randomness of particle-distribution in a mixture by comparing the observed variance with the theoretical variance. In addition, the method for estimating the theoretical variance of samples by a stratified sampling and the mixedness by the analysis of variance ratio are given in case that the theoretical variance is not known beforehand.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_77_publisher_11":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"室蘭工業大学","subitem_publisher_language":"ja"}]},"item_77_relation_15":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"40003627666","subitem_relation_type_select":"NAID"}}]},"item_77_source_id_12":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05802415","subitem_source_identifier_type":"PISSN"}]},"item_77_source_id_14":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00238225","subitem_source_identifier_type":"NCID"}]},"item_77_subject_9":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"420.4","subitem_subject_scheme":"NDC"}]},"item_77_version_type_21":{"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_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":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"渡辺, 治夫","creatorNameLang":"ja"},{"creatorName":"WATANABE, Haruo","creatorNameLang":"en"},{"creatorName":"ワタナベ, ハルオ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-16"}],"displaytype":"detail","filename":"kiyo37_rikou_pp319-342.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kiyo37_rikou_pp319-342.pdf","objectType":"fulltext","url":"https://muroran-it.repo.nii.ac.jp/record/8087/files/kiyo37_rikou_pp319-342.pdf"},"version_id":"46177565-2b0b-4ca6-8ca6-c668b3215841"}]},"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":"混合度評価と質量基準粒子濃度","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"混合度評価と質量基準粒子濃度","subitem_title_language":"ja"},{"subitem_title":"Effect of Particle Mass-Concentration on Evaluation Mixedness","subitem_title_language":"en"}]},"item_type_id":"77","owner":"18","path":["151"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2014-03-04"},"publish_date":"2014-03-04","publish_status":"0","recid":"8087","relation_version_is_last":true,"title":["混合度評価と質量基準粒子濃度"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-12-15T03:23:39.333689+00:00"}
