Finally, a complete solution of separation of mechanical sources with narrowing-band in frequency domain is proposed.
最后，提出了基于频域分段窄带化的机械源分离整体解决方案。
2
The spectral linewidth narrowing is due to the common effect of squeezing and the radiation reservoir of the photonic band gap.
由于腔场压缩的出现与光子晶体带隙的共同作用，腔场发射谱的线宽变窄。
3
The pulse amplitude of narrow band operating approaches to that of broadband operating, it means that, the energy loss caused by narrowing spectrum is only a few.
