相长干涉 ( constructive interference ): 讯号互相干涉后产生更大的振幅。若两波刚好同相干涉,会产生最大的振幅,称为完全 相长干涉 。

This situation is called constructive interference.
这种情形称作相长干涉。
This situation is called constructive interference .
这种情形称作相长干涉。
So in this case where we're adding it together, this is going to be constructive interference.
在这个情况下,我们把它加在一起,这是相干干涉。
So, we'll start by taking a look at constructive interference, and another way to explain this is just to say again, molecular orbitals are a linear combination of atomic orbitals.
我们先来看一看相长干涉,另外一个解释它的方法就是说,分子轨道是原子轨道的组合。
And all we mean by constructive interference is that literally those two waves add together, such as the maxima are now twice as high, and the minima are now twice as low.
相干相长,相干相长也就是,说两个波加在一起,所以最大值变成2倍那么高,最低值变成2倍那么低。
Since we're talking about wave functions, since we're talking about the properties of waves, we don't only have constructive interference, we can also imagine a case where we would have destructive interference.
因为我们讨论的是波函数,因为我们讨论的是波的性质,我们不仅有相长干涉,我们也可以想象在,某种情况下会有相消干涉。
