傅里叶谱 meaning in Chinese
fourier spectrum
Examples
- Engineering cases indicated : to apply the techniques of resonant demodulation can pick up micro shock pulses of hearing fault , and through analyzing the impact power fault vibration signal characteristics in the fourier chart of the resonant demodulation , the fault diagnosis will be easier
工程实例表明，使用共振解调技术可以有效提取轴承故障微小脉冲冲击，通过在共振解调傅里叶谱图上分析冲击功率故障振动信号特征，可以较容易地进行故障诊断。
