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。

And what is plotted below is the actual wave function, so you can see it starts very high and then the decays down.

下面这画的是，波函数，你们可以看见它开始非常高,然后衰减下来。

Then you get successively deeper, II through IV, slow, irregular, high amplitude delta waves, and then once you reach stage IV you start going up again, up through stage III and II.

然后睡得越来越深，从第二到第四阶段，慢，不规则，高振幅的δ波，等你到达第四阶段，你又开始返回，第三阶段和第二阶段。
