The motion recorded is studied with respect to its mean kinetic energy as a function of the velocity and the number of the colliding shots and also of the logarithmic decrement of the pendulum. The results of experiments are compared and found approximately agreeing with those expected from the theory, in the case when the number of collision per second is small. When the number is very large some discrepancies are observed which may be explained by the increase in the effective mass as well as the effective damping of the pendulum on account of the swarm of shots surrounding the vibrating mass. It is pointed out that the general formal characters of the motion of the pendulum here studied are essentially similar to that of some or other types of motion of the earth as recorded by seismographs. An important bearing of this fact upon the fundamental problems of seismology is briefly suggested.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"135148","nameIdentifierScheme":"WEKO"}],"names":[{"name":"寺田, 寅彦"}]},{"nameIdentifiers":[{"nameIdentifier":"135149","nameIdentifierScheme":"WEKO"}],"names":[{"name":"中谷, 宇吉郎"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/0000035042","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京帝国大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00029699","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408972","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"453","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute, Tokyo Imperial University"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"地震研究所"},{"subitem_text_value":"理化学研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Terada, Torahiko"}],"nameIdentifiers":[{"nameIdentifier":"135146","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakaya, Ukitiro"}],"nameIdentifiers":[{"nameIdentifier":"135147","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-27"}],"displaytype":"detail","filename":"ji0050008.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ji0050008.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/35042/files/ji0050008.pdf"},"version_id":"30edfa8a-36ca-4314-a55b-da9c9f26a6d7"}]},"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":"Experiments on the Effect of an Irregular Successsion of Impulses upon a Simple Vibrating System","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Experiments on the Effect of an Irregular Successsion of Impulses upon a Simple Vibrating System","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["5277","5278"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2008-06-06"},"publish_date":"2008-06-06","publish_status":"0","recid":"35042","relation_version_is_last":true,"title":["Experiments on the Effect of an Irregular Successsion of Impulses upon a Simple Vibrating System"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:09:51.325544+00:00"}
