常見例句雙語例句The amplitude ratio of the mainlobe to sidelobe of window function is an important index and so is the maximal energy ratio.窗函數(shù)的主辨與旁辨的振幅比和最大能量比都是窗函數(shù)的重要性能指標(biāo)。Q values of P, S and coda of varied rocks have been measured by methods of amplitude ratio, energy, and coda from pulse propagational spectra.本文采用脈沖傳播譜振幅比法、能量法、尾波法分別測多種巖樣的P波Q值、S波Q值及尾波Q值。Based on propagation theory of plane wave, it is suggested that coherence in a crack could be indicated by the amplitude ratio or the coupling dynamic stiffness (CDS).依據(jù)平面波的傳播理論提出由振幅比或裂隙耦合動剛度表示裂隙的粘合程度。 返回 amplitude ratio
