频率分量 meaning in English
frequency components
Examples
- Choose the frequency from 14 to 16 bark as the embedding positions which below the masking threshold . then change the dct coefficient with the certain strength of
选用中低频14 16bark段在掩蔽阈值以下的频率分量作为嵌入点,对该嵌入点的dct系数以一定嵌入强度作修改来实现秘密信息的嵌入。 - This dissertation put forward a method of eliminating noise and reconstituting broken wires signal and inquired the space - frequency range of the signal ripple resulted from tensile stress on the mfl signal curve
提出了去除干扰重组断丝信号的方法，分析了漏磁曲线上应力波纹的空间频率分量。 - Fourier transform method use high order frequency to analyse and imitate nonlinear and non - stationary data . emd method based on local characteristic time scale of the data is more fit to analyse nonlinear and non - stationary data than fourier transform method
Emd基于信号的局部时间特征尺度分析原信号，克服了傅里叶变换用高次谐波频率分量拟合非线性、非平稳信号的缺点。 - In order to avoid spectrum error due to energy leakage , the thesis research on identification of parameters of two close frequency components in discrete spectrum analysis , and simulation result shows the validity of the method
针对由于能量泄漏造成的频谱误差，深入研究了密集频谱的频域参数识别法，从理论上加以推导，并通过仿真证明了该方法的有效性，可以识别1个频率分辨率以内的两临近频率分量。 - So the pipe system sends out noise because of resonance . especially the frequency 250hz of pulsating water is in close proximity to natural frequency of pipe , so the 250hz is a dangerous frequency to the pipe system . there is another reason why the noise is reached to 110db ( a ) in pump room that the noise is magnified by the cistern because of the resonance of cistern
特别是激励频率为250hz的频率分量恰好与管道系统的固有频率相接近，其引起的管道振动对噪声的贡献最突出，同时也与水泵房房腔的固有频率相接近，从而引起房腔共鸣发声，使噪声进一步被放大，以至于噪声最大处高达105db ( a ) 。
