Today our countdown clocks and countdowns continue to oscillate between genesis and apocalypse.

今天，我们的倒计时时钟和倒计时继续在创世记和天启之间摆动。

This is the de Heer circle, when rotating continuously, it also appears to oscillate back and forth.

这就是德赫尔圆，当连续旋转时，它也会出现来回振荡的现象。

Wind causes the mast to oscillate, or move back and forth. It does not spin around. So it creates no risk to birds and bats.

风让桅杆震荡或来回摆动，并不旋转，所以不会对鸟类和蝙蝠构成危险。

After 100 days, they thawed the organs with an alternating magnetic field, which caused the nanoparticles to oscillate and evenly warm the tissue.

100 天后，他们用交变磁场解冻器官，这导致纳米粒子振荡并均匀地加热组织。

This same instability also enhances our frequency selectivity, for a given hair cell tends to oscillate best at the frequency at which it normally trembles when it's not being stimulated.

同样的不稳定性也能增强我们对频率的辨识度，因为某个毛细胞摆动的最佳频率，一般是它在不受刺激时自然抖动的频率。

As we discussed in Episode 21 – on Files and File Formats – this signal is the magnitude of displacement, of a diaphragm inside of a microphone, as sound waves cause it to oscillate.

正如我们在第 21 集关于文件和文件格式中讨论的那样，该信号是位移的幅度，即麦克风内部隔膜的位移量，因为声波会导致其振荡。
