So if we're subtracting the interference term, what we have here now is destructive interference.

如果我们减去干涉项，我们得到的就是相消干涉。

So if we write out every term individually, what we end up with is essentially just the probability density for the first atom, then the probability density for the second atom, and then we have this last term here, and this is what ends up being the interference term.

如果我们把每一项都写出来，最后得到的就是,第一个原子的概率密度，然后是第二个原子的概率密度，然后是这最后一项，这就是干涉项。

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。

And again, if we write out what all the terms are, we again have 1 s a squared plus 1 s b squared, but now what we're doing is we're actually subtracting the interference term.

同样，如果我们把所有的项都写出来，同样我们有1s平方加上1sb平方，先现在我们做的是,我们要减去干涉项。
