1) acoustic band-gap
声波禁带
1.
It is concluded that:one,the bigger leakage pres- sure,the faster sound pressure decay,and two,the bigger leakage aperture,the bigger breadth of acoustic band-gap, the lower center frequency of acoustic band-gap.
以通过管阵列的泄漏声波信号为对象,分析其经过管阵列传播后的频谱特性,得到声波的变化规律:泄露压力越大,声压衰减的越快;泄露孔越大,声波禁带宽度越大,声波禁带中心频率越低。
2) phononic band gap
声子禁带
3) acoustic bandgap
声禁带
4) stop-band
波矢禁带
1.
It is shown that the formation and variation of the stop-bands in wavevector diagrams are strongly dependent on the light wavelength and the structural parameters.
实例计算结果表明，波矢量图中的波矢禁带的产生和变化强烈地依赖于光波长和结构参量，随着周期长度的增大或光波长的减小，波矢量图将变得更加复杂，并将产生更多的波矢禁带。
5) elastic wave stop band
弹性波禁带
6) acoustic wave entrainment
声波夹带
1.
A new approach is proposed for the measurement of micron grade and sub-micron grade single particle size by the use of acoustic wave entrainment.
文中提出了一种新的利用声波夹带测量微米级和亚微米级单颗粒粒径的方法。
