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。
The constructive interference effect between symbols is decreased with this technique.
利用这种技术可以有效的降低符号间相干干扰。
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。
All right. So we see constructive interference, of course, we can also see destructive interference.
好了，我们看到的是相长干涉，当然我们也会看到相消干涉。
So in this case the cross term represents constructive interference between the two 1 s atomic wave functions.
在这种情况下交叉项代表两个，1s原子波函数的相干干涉。
So if we have constructive interference between the two, what we're going to see is our molecular orbital looks something like this.
如果两者是相干干涉，我们看到分子轨道，看起来是这个样子的。
Constructive interference of atomic coherence leads to electromagnetically induced absorption, which is a new kind of coherent effects.
原子相干对吸收的相长干涉导致电磁诱导吸收，这是一类新的相干效应。
So let's think of them a little bit more by graphing the amplitude of the wave, and seeing how we can have this constructive interference.
让我们把波的，振幅画出来考虑一下，我们怎么能得到这种相长干涉。
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。
In this case is it constructive or destructive interference?
在这种情况是相长干涉还是相消干涉？
