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 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。
