Current in resistors is in phase with voltage.

电阻器中电流与电压同相。

Since the voltage and current peaks occur at the same time, the two are said to be in phase.

由于电压峰值和电流峰值 同时出现，因此称两同相。

By seeing how in or out of phase two light waves  are, an observer can infer the relative speed of the waves.

通过两个同相异相，可以推断出相对速度。

If undisturbed, the  beams will be in phase, meaning their frequencies will subtract each other, and no light will arrive  at the photodiode.

如果不受干扰，束将同相，这意味着它们频率将相互减去，并且没有到达电二极管。

The gravity waves moving through the inversion  created enough lift that a strong updraft was formed and it moved in phase with the peak of the  gravity wave.

通过反转重力产生了足够升力，形成了强大上升气流，并且与重力峰值同相移动。

In that case, vertically polarized light would actually be a superposition of these two diagonal wiggling directions, at least when both are in phase with each other, and they have the same magnitude.

在这种情况下，垂直偏振实际上是这两个对角摆动方向叠加，至少当两彼此同相并且它们具有相同幅度时。
