So this means that we have two of the electrons are lowered in energy, but two are raised in energy.

这意味着两个电子能量降低,两个电子能量升高。

That quantity in parenthesis, I have a mass which is a positive number. Something raised Something raised to the fourth power has got to be positive.

顺便说一句,质量这个量是个正数,四次方的值,肯定是正数。

Well, we were raised by different parents and we have different genes We can't tell-- My brother and me might share all sorts of things in common but we have the same parents and the same genes, fifty percent of the same genes ? So how do we tell what's causing us to be alike?

因为我们的父母不同,我们有不同的基因,我哥哥和我,可能会有很多共同点,我们的父母是一样的,有50%的基因相同,那是什么导致我们相似的呢？

So we can compare the two electron configurations, and we can actually think about what we figure out from them, we see that two are lowered in energy, two electrons are raised in energy, so we have no net gain or no net loss in energy for h e 2.

我们可以比较两种电子构型，我们可以考虑,我们发现这，两个电子能量变低，两个电子能量升高，所以在He2里没有净的能量得失。
