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。
