摘要
To study scale characteristics of heterogeneities in complex heterogeneous medium, this paper constructed random and uniform media models. Scale characteristics of three kinds of seismic waves, namely direct wave, scattered wave and reflected wave, in random and uniform media were studied and analyzed by wavelet transform. The results showed that three kinds of seismic waves behaved different scale characteristics, and direct wave behaved large scale characteristic, and scattered wave was second, and reflected wave behaved small scale characteristic.
