Perforated plates correspond to heterogeneousmedia.
多孔板相当于均匀介质。

Such amplitude variations would be predicted on the basis of principles governing seismic velocities in heterogeneousmedia.
按照在非均匀介质内确定地震速度的原理,应能预测这样的振幅变化。
3
A method for describing heterogeneousmedia and fractional Brownian motion are introduced. The spectral density function of fractional Brownian motion is used to simulate the heterogeneousmedia.
