The result is accord with geological sample and sediment chart, so this method can be applied on sediment classification of narrow-bandpulse echo sound signal.
分析结果与地质采样结果及海图均吻合，说明本文提出的方法应用于窄带脉冲信号的海底底质分类是适用的。

The pulse amplitude of narrowband operating approaches to that of broadband operating, it means that, the energy loss caused by narrowing spectrum is only a few.
窄带运转的脉冲幅度接近宽带运转，这意味着由于谱线压窄引起的能量损耗不大。
3
The invention realizes three-band output, and the cavity structure can ensure high energy and narrowpulse width three-band laser output and also can reduce element damage.
