Because the DM-10 and B-100 use no global negative feedback, the damping factor is very modest.
由于糖尿病- 10和B - 100使用没有全球性的负反馈，阻尼因素是非常温和的。

Excitation adjustor which can eliminate negative-damping is designed according to the oscillation mechanism of the synchronous machine and the factors which affect the excitation control.
根据同步发电机的振荡机制及影响励磁控制的各要素设计了可消除负阻尼的新型励磁控制方法。

Paralleling negative stiffness can not only decrease the isolator's natural frequency, but also improve the damping characteristic and increase the internal resonant frequency of the isolator.
