energy spectrum analysis meaning in Chinese
能谱分析
Examples
- This algorithm applied to real system produces a good result . third we investigate the method for feature extraction , and put forward two methods base on wavelet analysis : coefficients character obtained by wavelet multi - resolution analysis and energy spectrum analysis using wavelet pack technique , from which a feasible feature vector is created
研究了基于小波的特征提取方法，提出了两种基于小波变换的特征提取方法：基于小波变换系数特征和基于小波包分解的能量特征，从而得到了故障信号的时域和频域特征。 - To solve cylinder liner crack problem of a certain large marine diesel engine , the crack was studied and analysed being aimed at the cylinder liner which created the crack by means of colouring crack detection , electron microscope scanning , energy spectrum analysis , chemical composition analysis and so on . also the temperature distribution and the stress condition of the cylinder liner were researched and analysed utilising measurement on board ship and finite element analysis method . finally the main causes of the cylinder liner crack were synthetically analysed and determined
