因为固有谐振电路不用来设计合成器vco。
Synth VCOs aren't designed using naturally resonant circuits.
由于箱式浮体结构的低阶固有频率很低，相应的弹性振型的响应与刚体运动耦合，结构在波浪中没有发现明显的低阶弹性模态谐振。
No significant resonance of the low flexible body modes is found due to the coupling of the responses among these modes and the rigid body modes.
提出消除振动的主要对策，包括避免固有频率接近引起的谐振、减少压力脉动及接蓄能器吸收振动等。
The vibration dispose countermeasures which includes preventing resonance caused by same inhere frequency, lessening pressure puke and using accumulator to absorb vibration etc.
