翻译成地道的英文表达：基于分层土的周期波屏障结构产生了两条表面波带隙（图3a），分别位于0-4.13Hz和8.78Hz-9.51Hz，带隙宽度分别为4.13Hz和0.73Hz，其中由于第一带隙在0Hz附近，又被称为零频阻带。

Based on the periodic wave barrier structure of a layered soil, two surface wave band gaps (as shown in Figure 3a) are generated, located respectively at 0-4.13Hz and 8.78Hz-9.51Hz, with band gap widths of 4.13Hz and 0.73Hz. The first band gap is also known as the zero frequency stop band due to its location near 0Hz.
