the different states want corporations to register and therefore the rules are such that they protect the corporation with the poison pills I can't get into all these different things - -stagnant boards, poison pills- and I think if you just change some of that we could be like, for instance, England is much better.
每个州都想让自己的企业注册,所以现在的规则就是,各州都用毒药丸保护企业,我不能干涉所有的这些东西,-没有进步的管理层，毒药丸-,如果你愿意改变其中一些方面的话,我们就会像，例如，英国企业的情况比美国好多了。

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.

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。
