A transition layer in this basic analysis is modeled by a homogeneous isotropic elastic layer, and the phenomena is explained by the reflection and transmission coefficients. Representative numerical examples of the coefficients to the soft layer and the hard layer show us some clues to evaluate the transition layer materials. Numerical results are made sure by the energy conservation law of wave motion. Perfect penetration of wave energy (N on-reflection phenomena) appears depending on the wavelength. The penetration accompanied by the resonance of the layer is caused even though the incident angle is larger than the critical angle of incidence.The basic analysis and formulation described here may be helpful to make further study of ultrasonic non-destructive evaluation of complex materials.", "subitem_description_type": "Other"}]}, "item_10002_publisher_30": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "秋田大学鉱山学部"}]}, "item_10002_source_id_27": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03898040", "subitem_source_identifier_type": "ISSN"}]}, "item_10002_source_id_35": {"attribute_name": "NCID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00010307", "subitem_source_identifier_type": "NCID"}]}, "item_10002_version_type_37": {"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": "大好, 直"}], "nameIdentifiers": [{"nameIdentifier": "3960", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "随, 広軍"}], "nameIdentifiers": [{"nameIdentifier": "3961", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "OHYOSHI, Tadashi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "3962", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "SUI, Guang Jun", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "3963", "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": "2017-02-16"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "oyoshi7.pdf", "filesize": [{"value": "612.6 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 612600.0, "url": {"label": "oyoshi7.pdf", "url": "https://air.repo.nii.ac.jp/record/1165/files/oyoshi7.pdf"}, "version_id": "2168cb75-53a9-41cb-82b0-ffbec0073edc"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "弾性波", "subitem_subject_scheme": "Other"}, {"subitem_subject": "遷移層", "subitem_subject_scheme": "Other"}, {"subitem_subject": "反射", "subitem_subject_scheme": "Other"}, {"subitem_subject": "透過", "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": "弾性波の遷移層による反射と透過", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "弾性波の遷移層による反射と透過"}]}, "item_type_id": "10002", "owner": "3", "path": ["775"], "permalink_uri": "http://hdl.handle.net/10295/1061", "pubdate": {"attribute_name": "公開日", "attribute_value": "2008-08-25"}, "publish_date": "2008-08-25", "publish_status": "0", "recid": "1165", "relation": {}, "relation_version_is_last": true, "title": ["弾性波の遷移層による反射と透過"], "weko_shared_id": 3}
