[求助] 这段关于季氮作用的描述,应该怎样理解

Theoretical studies support the hypothesis that the presence of quaternary-type nitrogen favors O2 adsorption at carbon sites on the zigzag edges located adjacent to quaternary-type nitrogen . The incorporation of electron-accepting nitrogen atoms creates a relatively high positive charge density on adjacent carbon atoms;
nitrogen becomes more electronegative and creates a net positive charge on the adjacent carbon atoms .As a result, the adsorption of O2 on nitrogen doped CNTs becomes easier leading to an improved electrocatalytic activity of these materials towards ORR in alkaline media 。(注:quaternary-type nitrogen表示季氮,CNTs表示C纳米管)
本人电学基础比较薄弱,上面这段话有点不大理解,特别是中间那句,求各位大神指教~
