The effect is a phenomenon in which the largest particles end up on the surface when a granular material containing a mixture of objects of different size is shaken. In this research, the behaviors of various size particles are analyzed by numerical simulations using multiparticle model.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064734066","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11567475","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院工学系研究科航空宇宙工学専攻"},{"subitem_text_value":"アーサー・D・リトル (ジャパン)"},{"subitem_text_value":"宇宙航空研究開発機構月・惑星探査プログラムグループ : 宇宙航空研究開発機構宇宙科学研究本部"},{"subitem_text_value":"宇宙航空研究開発機構月・惑星探査プログラムグループ"},{"subitem_text_value":"宇宙航空研究開発機構月・惑星探査プログラムグループ"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Aeronautics and Astronautics, Graduate School of Engineering, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Arthur D.
