spectral components meaning in Chinese
光谱分量
Examples
- The ability to provide control for time - varying spectral components of a sound is of critical importance for sound synthesis
能够控制声音的时变频谱要素对声音合成来说是至关重要的。 - During the acoustic logging data process , the information of time - frequency of related spectral component can not be provided generally by means of fourier transformation ( ft )
摘要在声波测井资料处理的过程中，傅里叶变换通常不能提供有关谱分量的时间局域化的信息。 - Based on the existing spectral independent component analysis ( spectral ica ) and non - negative constrained decomposition , a moving time window is introduced , and multiple dominant spectral components are extracted within the short - time window
结合已有的频域独立成分分析方法以及带约束的非负分解处理，引入时间滑动窗口，在短时窗内动态提取多重主导功率频谱。 - 2 ) fourier amplitude spectrum analysis : ( 1 ) the fourier amplitude spectra decrease with the increment of depth ; and the components of fourier spectrum become complex in near - surface . ( 2 ) the fourier amplitude decrease faster in shallow soil level , and smaller in deep soil level . ( 3 ) compared with the deepest bedrock fourier spectrum , spectral components of higher than 5 hz decrease with depth decrease
2 .地震动傅立叶振幅谱沿深度的变化规律( d随着深度的增大，傅氏谱振幅逐渐减小;越接近地表傅氏谱的频谱成份越多，形状越复杂;傅氏谱振幅值在浅层沿深度的下降梯度较大，在深层下降较小; “土层/基岩”场地的基岩内_匕下两测点的地震动频谱沿深度几乎不变，傅氏谱十分相似; d基岩以上的土层测点，高于shz的高频成分减少。 - In the single - photon resonance case , for large area input pulses , the spectral components oscillating around 32 appears in the spectrum due to the strong secondary excitation making the two - level model invalidity and the multi - level model should be used to describe this molecule
在单光子共振情况下，即入射脉冲频率等于1 、 2能级之间的共振频率，对大面积入射脉冲，由于强的二次激发的作用，电场频谱中出现了在32附近振荡的频率成分， 32是2 、 3能级之间的共振频率，说明对大面积入射脉冲二能级模型已经失效，需要采用多能级模型来描述分子介质。
