In dvd focus servo system , the warp of the disc induces periodic disturbance whose frequency is same as the rotation frequency of the disc
摘要在dvd聚焦伺服系统中，光盘翘曲会导致产生与光盘转动频率相同的周期性扰动。
Time domain synchronous averaging can reduce the signal not coherent to rotation frequency effectively , and extract the repetitive signals directly related to machine operation condition
而时域同步平均可以有效衰减与回转频率无关的干扰，提取与工作状态直接相关的周期信号。
We apply the continuation theorem to the dnls equation and prove that when the damping force 6 and the driving force h satisfy h > , the discrete multibreathers with the rotation frequency exist , where >
然后将此定理应用于高维dnls方程，证明了当阻尼和外力h满足h时，存在频率为的离散多重呼吸子，其中。
The ship radiated noise is analyzed and its 4 features are extracted from the envelop spectrum . the envelope of ship noise waveform can be demodulated utilizing hilbert transform , and the spectrum components with line rotation frequency of propeller shaft are extracted effectively by bispectrum , 1 ( 1 / 2 ) spectrum and 2 ( 1 / 2 ) spectrum analysis
对于通过希尔伯特变换解出的舰船辐射噪声包络信号进行高阶统计量分析，有效地提取出了舰船噪声的双谱、 11 / 2维谱、 21 / 2维谱等方面的特征。
