It has been explained by the decomposition of carbonate. The carbon content in the sample ignited at 550℃ for 6 hours was analysed by the CHN-Analyzer. The amount of carbonate calculated from the carbon value was lower than the difference; therefore, this difference was not explained by the decomposition of carbonate only. We assumed that the sample ignited at 550℃ for 6 hours contained H2O because it was shown to contain hydrogen by CHN-Analyzer. If the remaining H2O was removed at 900℃, then the difference in ignition loss of the two conditions was explained well. Consequently, we concluded that the ignited samples contained water of crystallization, and the difference in ignition loss at low and high temperatures is caused by the decomposition of carbonate and discharge of water of crystallization.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"浅海域の堆積物の強熱減量の測定で,550℃で強熱した場合,700~900℃で強熱した時より,炭酸カルシウムが分解しない分だけ値が低いとされている.しかし,実際にはかなり低い場合が多く炭素カルシウム以外に分解が抑制されている物質の存在が推定された.そこで,CHNコーダーを用いて,550℃ 6時間強熱した場合と900℃ 1時間強熱した場合にその前後の炭素,窒素,水素の変化から強熱温度の影響を検討してみた.その結果,次のことが明らかになった.550℃6時間と900℃ 1時間の強熱減量に明らかな差が認められたが,その差は強熱後の試料のCHNコーダー分析して得られた炭素量から,炭酸塩の分解だけでは説明できないことが明らかになった.しかし,強熱した試料から水素が検出され,その水素は試料中に残留していた結晶水に由来するものと考えられた. 550℃ 6時間の強熱後に残留していた結晶水が900℃ 1時間の強熱で逸散したとして計算すると,550℃ 6時間と900℃ 1時間の強熱減量の差を十分に説明できた.したがって,低温での強熱減量と従来の高温での場合との差は,炭酸カルシウムの分解だけでなく結晶水の放出によって起こることが明らかになり,このことは低温での強熱減量がより有機物量の指標として有効であることを示している.さらに,結晶水の放出温度の検討から,分析にあたって強熱温度を変えることは誤差を一定にさせるためにも好ましくないことがわかった.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Sea National Fisheries Research Institute","subitem_publisher_language":"en"}]},"item_10002_radio_30":{"attribute_name":"作成者","attribute_value_mlt":[{"subitem_radio_item":["吉","田"],"subitem_radio_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"js_k_43_105_115","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本農学文献記事索引(agriknowledge)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010501893","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00186380","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0021-4620","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"日本海区水産研究所","affiliationNameLang":"ja"},{"affiliationName":"ニホンカイクスイサンケンキュウジョ","affiliationNameLang":"ja-Kana"},{"affiliationName":"Japan Sea National Fisheries Research Institute","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Sato, Yoshinori","creatorNameLang":"en"},{"creatorName":"佐藤, 善徳","creatorNameLang":"ja"},{"creatorName":"サトウ, ヨシノリ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Sato","familyNameLang":"en"},{"familyName":"佐藤","familyNameLang":"ja"},{"familyName":"サトウ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Yoshinori","givenNameLang":"en"},{"givenName":"善徳","givenNameLang":"ja"},{"givenName":"ヨシノリ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"1898","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"40371900","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=40371900"}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"長澤, トシ子","creatorNameLang":"ja"},{"creatorName":"ナガサワ, トシコ","creatorNameLang":"ja-Kana"},{"creatorName":"Nagasawa, Toshiko","creatorNameLang":"en"}],"familyNames":[{"familyName":"長澤","familyNameLang":"ja"},{"familyName":"ナガサワ","familyNameLang":"ja-Kana"},{"familyName":"Nagasawa","familyNameLang":"en"}],"givenNames":[{"givenName":"トシ子","givenNameLang":"ja"},{"givenName":"トシコ","givenNameLang":"ja-Kana"},{"givenName":"Toshiko","givenNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"2692","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ignition loss;
