- The power magnitude of main peak frequency of dynamic tapping torque can be used for on_line detecting the tap wear. 提出了在频域内采用动态攻丝扭矩主要峰值频率的功率值实时检测丝锥磨损的方法。
- The products are primarily used in 1.F.T,therefore appropriate T.C types shall be used to match ferromagnetic cores.If not,peak frequency will shift. 一、本品主要用于中周配套，因此选用电容器之T.;C（温度补偿）类别应与瓷芯相匹配，如不匹配，易造成高低温谐振飘移。
- Common methods classify animals by their difference in sound pulse rate, wave form structure in time domain and main peak frequency in frequency domain et cetera. 传统的鸣声分类时一般依据不同种动物鸣声信号在时域波形上的波形结构和脉冲率等的不同，功率谱上相对幅度最大所对应的频率即主频的不同来进行分类。
- In addition, considering the origin, the mechanism and the framework of the pulse signals, peak value, peak frequency, center of gravity (cg), gravity frequency of power spectrum, AR model parameter, the value of SER and Renyi entropy were extracted. 并且根据脉搏信号的产生机理、性质,提取了功率谱峰值、功率谱重心及其频率,AR模型系数,SER值,Renyi信息量等多个特征量。
- The logarithmic cospectra uw and wT fall asf-4/3. The behavior of the reduced peak frequency fm shows that the turbulence range moves toward high frequency due to the terrain influence. 协谱uw,wT及近地层的uT协谱在惯性区服从-4/3次律。
- During the stepped and dart leader propagating from cloud to ground, the peak frequency band of the average energy spectra reduces from high to low frequency band, indicating that the size of the breakdown is increased gradually. 梯级先导和直窜先导过程初始阶段辐射能量主要集中在较高频段,而接近地面时则集中在较低频段,表明先导在向地面发展过程中放电尺度逐渐增大。
