voltage spectrum meaning in Chinese
电压频谱
Examples
- Studies of photoelectric property about nanocomposite oxide with sno2 and a - fe2o3 using sol - gel method we prepared nanocomposite oxide with sno2 and a - fe2o3 , we analyzed it ' s property with xrd uv spectra surface photo voltage spectra ( sps ) and field induced surface photovoltage spectra ( fisps )
一fez仇复合氧化物纳米粒子，并用xrd 、紫外可见吸收光谱、表面光电压谱( sps )以及场诱导表面光电压谱( fisps )进行了分析和表征。 - For ac discrete digital signal , the zero - calculating method is applied to calculate the true zero in the periodic signal . for the measurement of ac and dc voltage spectrum , the faster fourier transform ( fft ) is used . to measure dc voltage ripple spectrum and frequency modulation of ac voltage , the digital filter is used
其中对于交变的离散数字量，采用零点捡出技术计算周波信号的真实过零点；对于交直流电压频谱，采用快速傅立叶变换进行频谱分析；对于直流电压脉动和频率调制，采用数字滤波器进行滤波后再做分析处理。
