证据显示，太快地吸入过多的氧气可能夺走单电子的分子，形成自由基。

Evidence suggests that pumping in too much oxygen too quickly can strip the molecule of a single electron, creating a free radical.

But now it's going to make more sense because in that case we were just talking about single electron atoms, and now we're talking about a case where we actually can see shielding.

但是现在能讲得通了,因为在那个情况中我们仅仅是现在我们讨论的是,讨论单电子原子，看到屏蔽的案例,我们能看到屏蔽。
