Harmonics of these normal forces will resonate the naturalfrequencyresonant modes of the stator structure so producing acoustic noise.
这些简正力量泛音将共鸣定子结构的自然频率共振方式如此导致音响噪声。

Resonant sensor system is a kind of quasi-digital measuring device utilizing the effect that the naturalfrequency of the resonator changes according to the measured frequency.
谐振式传感器是利用某种谐振子的固有频率随被测物理量的变化进行测量的一类准数字式装置。

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