Response Spectrum)による判定法と速度による判定法がある。補正手法については、衝撃などの瞬時現象に最も適しているウェーブレットを用いた補正手法の手順を確立し、手法の信頼性について基礎実験による検証を行ない、本手法の有効性を確認した。","subitem_description_type":"Abstract"}]},"item_3_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"JP-2002-256871","subitem_description_type":"Other"},{"subitem_description":"US-Patent-Appl-10/652,034","subitem_description_type":"Other"},{"subitem_description":"EU-03255425.5","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
