broad band response 中文意思是什麼
broad band response
解釋
寬帶反應-
754 horizontal - component digital broad - band records in western north america are processed. the acceleration response spectra are calculated and used as part of the database. the response spectrum values are estimated by the earthquake magnitude definition and are used as another part of the database
將美國西部地區作為參考地區,對美國南加州地區的數字寬頻帶記錄進行了搜集與處理後作為觀測資料,共754條水平向記錄,與利用震級定義所估計的反應譜值一起,用統計回歸的方法建立美國西部長周期加速度反應譜衰減關系。 -
Then the transform method and the digital broad - band data from china is applied to obtain the wide period attenuation relationships for horizontal acceleration response spectra of eastern china and western china in rock sites ( c, = 5 % )
最後用常規的轉換方法,並加入我國158條水平向寬頻帶數字記錄,建立了中國東部和西部地區的水平向基巖寬周期( t = 0 . 04 - 20s , = 5 )加速度反應譜衰減關系。 -
The reliability of the observation data in long period range is particularly inspected. this is done " by verifying the instrument response characteristic, examining the signal - to - noise ratio, comparing the recovered ground motions and response spectra from the velocity type and acceleration type digital broad - band records
對于速度型和加速度型的數字寬頻帶記錄,從儀器特性、恢復的地面運動對比、信噪比研究、反應譜對比等方面研究這類記錄在長周期段的可靠性。
