As these waves pound against the sea floor, they generate a constant vibration with a frequency of about ten millihertz, much too low for humans to hear but easily detectable with seismometers.

当这些压力波撞击海床时，会产生一种频率为0.01赫兹的连续振动，而对我们人类而言这个频率太低了，所以根本听不到，但却很容易被地震仪侦测到。

Maxwell showed that light was a vibration in the electromagnetic field, and that it travelled at a constant speed, c, in a vacuum.

马克思·威尔指出光是种电磁波，其在真空中的传播速度是个常数c。

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.

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。

It stressed that there was occasional, but no constant vibration during either game.

The constant vibration and roaring of the engine had left me numb and had worn the paint off my helmet where it rested against the inside wall.
