我们可以说我们在这,有正相位而这有负相位。

So we would say we have a positive phase here and a negative phase there.

精确得控制光子相位是基于独特得组合负和正的折射率器件。

This exact control of optical phase is based on a unique combination of negative and positive refractive indices.

但仔细观察，就会发现在他们的划水技术中，没有踉跄，没有暂停，更没有被钩住和死点——他们拥有优秀的节凑和时机，正无缝地从一个相位转到另一个相位。

But look carefully, there are no lurches, pauses, hitches or dead spots in their stroke technique - they have excellent rhythm and timing, moving seamlessly from one phase of the stroke to the other.

It's going to be positive in terms of its wave function or in terms of its phase anywhere where y is positive.

只要ｙ大于零它的波函数,或者说是相位为正。

And in terms of thinking about the phase of this p orbital, the phase is going to be positive anywhere where z is positive.

对于ｐ轨道的相位，在ｚ大于零的地方都是正的。
