However the transparency ratio, which is here defined as a ratio of the transparencies of each sample measured on the same condition, can be a objective standard for estimating turbidity. In the present paper, the concept of transparency ratio is derived from the Beer‐Lambert's law and the validity of the transparency ratio is verified by field data. Geometrical calculation for the intensity of incident ray through a transparency apparatus brought a practical table for modifying transparency and led to the conclusion that the modified transparency should be used to obtain the transparency ratio for turbid water.","subitem_description_type":"Abstract"},{"subitem_description":"透視度は測定者の主観や日照条件に大きく影響され，\nこれを用いて水質汚濁を客観的に評価するのは難しい。\nしかし同一条件で測定された個々の試料の透視度の比を\nとることによって濁度を推定すめための客観的な尺度と\nなり得る。本論文ではBeer-Lambertの法則から透視\n度比の概念を誘導し，現場測定値を用いてその有効性を\n確認した。加えて，透視度測定における光路を幾何学的\nに計算し，透視度比による水分汚濁評価の精度について\n考察した。その結果，透視度が小さいときにはTable2\nに示した補正透視度を用いて比を求めることで透視度比\nの精度が向上することがわかった。こうした透視度比は\n一般市民の感覚を損なわない上に慣用的な透視度以上に\n水質汚濁の指標になりうると思われる。","subitem_description_type":"Abstract"}]},"item_4_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学生物資源学部"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-0471","subitem_source_identifier_type":"PISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10073846","subitem_source_identifier_type":"NCID"}]},"item_4_subject_16":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"519","subitem_subject_scheme":"NDC"}]},"item_4_text_18":{"attribute_name":"その他のタイトル","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"An Estimation Technique of Water Pollution with Transparency Ratio"}]},"item_4_text_63":{"attribute_name":"ノート","attribute_value_mlt":[{"subitem_text_value":"Agropedia提供データ"}]},"item_4_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Departmental Bulletin Paper / 紀要論文"}]},"item_4_version_type_15":{"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":"伊藤, 隆広","creatorNameLang":"ja"},{"creatorName":"Ito, Takahiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"溝口, 勝","creatorNameLang":"ja"},{"creatorName":"Mizoguchi, Masaru","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":"2017-02-18"}],"displaytype":"detail","filename":"AN100738460001404.pdf","filesize":[{"value":"349.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN100738460001404.pdf","url":"https://mie-u.repo.nii.ac.jp/record/5803/files/AN100738460001404.pdf"},"version_id":"0fcb5acb-8a47-462f-800b-b057633af1ad"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"water pollution","subitem_subject_scheme":"Other"},{"subitem_subject":"transparency","subitem_subject_scheme":"Other"},{"subitem_subject":"transparency ratio","subitem_subject_scheme":"Other"},{"subitem_subject":"turbidity","subitem_subject_scheme":"Other"}]},"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":"透視度比による水質汚濁の評価法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"透視度比による水質汚濁の評価法","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"13","path":["457"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-04-26"},"publish_date":"2007-04-26","publish_status":"0","recid":"5803","relation_version_is_last":true,"title":["透視度比による水質汚濁の評価法"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2023-10-12T06:05:26.417949+00:00"}
