The method to suppress the low-frequency components of the encoded sequence was proposed.
介绍了该编码的编码和解码步骤，并给出了控制编码后序列直流分量的方法。
Compared with classic wavelet technique, the proposed method can adjust not only the low frequency components of earthquake wave, but also the high frequency components.
和传统的小波分析相比，该方法不仅对地震波低频分量进行精确调整，还可对其高频成分实现类似的调整。
However SF6 introduces a significant resonance at 200 Hz to 250 Hz and, for noise dominated by low frequency components, such as traffic noise, this might be detrimental.
只是，六氟化硫（SF6）在200赫兹到250赫兹这个频段会产生很大的回声，而这对于主要为低频率成份构成的噪声比如交通噪声的应用而言可能会有害。
