Okay, so water. We did its Lewis structure last week, remember?

好的，那么水。 我们上周做了它的路易斯结构， 还记得吗？

Overall, the bonds are in both places so the actual structure is essentially an average of the two draw-able Lewis structures.

总的来说，债券在两个地方，所以实际结构基本上是两个可绘制的路易斯结构的平均值。

Resonance occurs when electrons are distributed around the molecule in a way that makes it impossible to draw with a single Lewis structure.

当电子以一种无法用单个路易斯结构绘制的方式分布在分子周围时，就会发生共振。
