In addition, we established explicit formulas for the construction of wavelets with arbitrary number of vanishing moments.
此外,我们为了构造具有任意消失矩的小波建立了一个显示公式。

The stopband zero suppression is a stricter design constraint than the vanishing moments, and can more effectively manipulate the stopband characteristics of filters.
阻带零点抑制是比消失矩约束更为严格的设计条件,能够更有效地控制滤波器的阻带特性。
You've got moments of fire and clarity, and go from greatly valuing yourself, to feeling your resolve vanishing like morning fog.
你有过洞若观火的时刻,从极好地评估自己出发,去感受你的决心像晨雾一样消失。
