估计准确度 meaning in English
accuracy of estimation
Examples
- Moreover , the higher harmonic order is , the lower distinguishability , and , as a result , the assessment accuracy becomes bad . considered its prominent localization both in time - domain and in frequency - domain , wavelet is used to the field of assessing harmonic impedance for the first time . we choose chaari wavelet because of its special band frequency characteristic , which can stratify signals synchronously and locate the distortion time precisely in assessing harmonic impedance
选取chaari小波为母小波，利用其特殊的带通特性，对在公共连接点( pcc )采样得到的电压，电流畸变波形进行同步分层， “突出”信号的畸变部分，提高了被分析信号的“信噪比” ，以利于谐波阻抗估计准确度的提高。
