更糟糕的是，因为没有面对面的情感提示，键出的字似乎有时候很难理解。

Worse still, without the emotional cues of face-to-face communication, the typed words sometimes seem difficult to interpret.

反转一个键的性质，这样一来素材中先前是键出的将变为键入，反之亦然。

Reversing the polarity of a key, such that material formerly keyed out will be keyed in, and vice versa.

So, there's actually another way to graph it where we can directly graph the dissociation energy or the bond strengths.

其实，还有另外一种画这个曲线的方式,可以直接画出离解能的大小,或者键的强度。

So let's just prove that to ourselves and figure out the bond order just using valence electrons.

让我们证明一下这一点,来看看只用价电子算出键序。

And, I know I need to come up with four symmetric equi-length bonds, and let's just see, let's draw the structure here.

我想我们需要,4个对称的等长的键，让我们画出CH4的结构。
