1) harmonic series of sounds
声群谐波
2) harmonic noises
谐波噪声
1.
The derivative of current deviation is directly controlled by voltage vector,and the control Pattern change over is made according to theamplithede area of current deviation so that the speed of current following is improved, and theharmonic noises are suppressed.
由于采用电压矢量直接控制电流偏差的导数，并根据电流偏差的幅值区域切换控制模式，从而不仅能提高电流跟随的快速性，而且抑制了跟随电流的谐波噪声。
3) harmonic self-bunching
谐波自群聚
4) harmonic energy group
谐波能量群
1.
According to the harmonic energy group, some parameters that are suitable to the analysis of non-stationary harmonics were pr.
该方法对信号进行恰当的小波包分解,使非稳态谐波的频谱落到某个频率子带上,将子带内的频谱作为一个谐波能量群。
5) harmonic to noise ratio
谐波噪声比
1.
The estimation of harmonic to noise ratio(HNR) in transmitted sound signals by wavelet transform was proposed.
应用小波变换估计传导语音的谐波噪声比,研究了不同发声方式、发音及声带病变对传导语音谐波噪声比的影响,并与口腔语音的谐波噪声比进行了对比研究,发现发不同元音时,传导语音谐波噪声比的变化范围是5dB,口腔语音谐波噪声比的变化范围为20dB;不同发声方式的传导语音谐波噪声比的变化范围可达18dB,口腔语音的变化范围为12dB。
6) sub-harmonic noise
次谐波噪声
