另外，呈现负阻尼效应的快速自动电压励磁调节装置的大量普及使用，则更进一步加剧了这一状况。
In addition, popularizations of fast automatic voltage regulator which show itself negative-damping even more worsen this situation.
结果表明，在换能器不同振动模态下，等效并联电容电阻并非恒定值，而且实际支承工况下换能器系统工作时存在负阻尼效应。
The result shows, under different vibration mode, equivalent parallel capacitance and resistance are not constant value. There is negative damp effect in transducer system at the operating mode.
