The roll is increased and severer than shipping state when the frequency of wave is similar as the natural rolling frequency of ships.

船舶在系泊或低航速状态下，当涌浪周期接近船舶自然横摇周期时，船舶摇摆比航行时更为剧烈。

And the effects of parameters such as joint deformation and incident frequency of wave on the intensity variation of EME were investigated.

同时，研究节理的变形和入射波频率对电磁辐射强度的影响。

However, the thickness of the system and the Angle of incident waves also influence the frequency of wave-guide and the quality factor of resonant modes.

就同一种准周期结构的系统而言，系统的厚度和入射波的入射角度对滤波频率以及共振模的品质因子都有重要的影响。

So, if something cycles through five wavelengths in a single second, we would just say that the frequency of that wave is five per second.

如果一个东西在一秒,内经历了五个波长，我们就说这个波的,频率是每秒5次。

Alright. So, since we have these terms defined, we know the frequency and the wavelength, it turns out we can also think about the speed of the wave, and specifically of a light wave, and speed and is just equal to the distance that's traveled divided by the time the elapsed.

好了，我们已经定义了，这些术语，我们知道了，频率和波长，现在可以来考虑,波的速度了，特别是光波的速度，速度等于它走过的距离,除以所用的时间，因为我们。

This development is made possible by a new wave of technology: radio-frequency ID chips the size of pepper grains, broadband wireless and Web-based "dashboards" enabling monitoring and management.
