翻译成地道的英文表达：基于实际分层土的有限排周期表面波屏障透射谱分析发现，在0-3.2Hz和8.2-9.4Hz范围内形成了两条衰减域（图4b），这与频散曲线的带隙计算结果基本一致。

The genuine layered soil limited-slab periodic surface wave barrier transmission spectra analysis reveals the formation of two attenuation domains in the range of 0-3.2Hz and 8.2-9.4Hz (Figure 4b), which is consistent with the bandgap calculation results of the dispersion curve.
