而为了检验任何一个结构是否有效，看它们是不是好的路易斯结构，我们要做的最后一件事就是检查形式电荷。

And the last thing we do for any of our structures to check them and figure out are these valid or not valid, are these good Lewis structures is to check the formal charge.

时钟的运转是通过检验点电荷与不同类型场源电荷之间的相互作用。

The runnings of the clocks depend on the interaction between a field-experiencing electric point charge and different field producing electric charge configurations.

So again, we should be able to check all of our formal charges and make sure they add up to 0, which they do, and that makes sense, because we have a neutral atom in terms of thionyl chloride.

因此同样地，我们可以检验一下,我们所有的形式电荷是否正确,确保它们加起来等于零，而它们确实是这样，这是合理的，因为亚硫酰氯是一个中性原子。

Also, formal charges can be checked, as I just said.

另外，我们可以检验一下形式电荷是否正确，就像我刚才说的。
