翻译成地道的英文表达：对建筑造成重大危害的地震波频率主要位于0-10Hz[33]，通过上述模型，计算了四种不同类型双梯度波屏障的透射谱（图7），其中灰色阴影区表示衰减域。

The seismic waves that cause significant damage to buildings primarily occur at frequencies between 0-10 Hz[33]. Using the aforementioned model, the transmission spectra of four different types of dual-gradient wave barriers were calculated (Figure 7), with the grey shaded area representing the attenuation zone.
