The electrostatic charge attenuation velocity of material reflects its leaking performance, electrostatic charge attenuationtime is used to evaluate anti-electrostatic performance of material.
材料的静电电荷衰减速度反映了其静电泄漏性能，所以可以用电荷衰减时间来评价材料的防静电性能。

Wavelet transform involves the two-variate function of frequency and time, which makes it convenient to simultaneously compensate for attenuation of seismic energy in frequency and time domains.
