SHIMOYAMA et al. (Chem. Lett., 10,2013,1987), where a>1 and b are constants. It is shown that the linear relation results from dissociation of organic polymer in the grains before accretion to parent body-sized objects by radiation that penetrates through the grains such as cosmic ray. Condensation of volatile molecules composed of C and N is also examined as a possible process to form precursors of organic compounds in carbonaceous chondrites. From an analysis of a model thermodynamic system, it is conjectured that this process can also realize the linear relation under certain conditions.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004519","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA10784627","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science/Department of Physics, Faculty of Science, Kyoto University"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1990-10-01"}],"displaytype":"detail","filename":"KJ00000036325.pdf","filesize":[{"value":"2.0 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000036325","url":"https://nipr.repo.nii.ac.jp/record/4519/files/KJ00000036325.pdf"},"version_id":"ad2266d0-9fab-4cdb-8d1d-46774f39c117"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"On the formation and processing of carbon and nitrogen compounds in carbonaceous chondrites","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"On the formation and processing of carbon and nitrogen compounds in carbonaceous chondrites"}]},"item_type_id":"1","owner":"4","path":["587"],"pubdate":{"attribute_name":"公開日","attribute_value":"1990-10-01"},"publish_date":"1990-10-01","publish_status":"0","recid":"4519","relation_version_is_last":true,"title":["On the formation and processing of carbon and nitrogen compounds in carbonaceous chondrites"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:19:40.299230+00:00"}
