那么，这些就是在我们需要在,不同的路易斯结构之间做选择的时候,我们如何用形式电荷来进行判断的各种方法。
So, these are the different ways that we can actually go ahead and use formal charge when we're choosing between different types of Lewis structures.
我们还可能遇到另外一种情况，那就是在我们需要进行，选择的两种路易斯结构中，形式电荷具有相似的绝对值。

那么在我们的第一个结构中，我们发现氮的形式电荷量是五减去四4,再减去二，因为我们开始有五个价电子，因此它的形式电荷量是负一。

在部分耗尽型SOI结构中，SOI中顶层硅层的厚度为50-90nm，因此沟道下方的硅层中仅有部分被耗尽层占据，由此可导致电荷在耗尽层以下的电中性区域中累积，造成所谓的浮体效应。
In partially depleted SOI, the top layer is between 50- to 90-nm thick. Silicon under the channel is partially depleted of mobile charge.
